Lionel GG1 JLC (not "Legacy) truck restoration in brass.

Here is a link to the original thread in O-27:

https://ogrforum.ogaugerr.com/...-sideframes-zinc-rot

I note that we are talking about JLC GG1s, not "Legacy" GG1s.  I will try to change the title.

Dean Brasseur says that the JLC mold was modified for the "Legacy" and that is why there will be no more castings.  That may put this problem in an entirely new light.  Suppose the Legacy casting actually fits?  I will ask.

Bob, assuming the end result isn't priced too high, I'd commit to two sets.

If the Legacy casting doesn't fit, it might be able to be made to fit, that would be a lot simpler.

Has anyone put the Legacy and JLC  sideframes together to get a comparison. If it's close to scale there shouldn't be much size difference. Maybe there wont be much to do if you recast the Legacy to fit JLC.

When I got stuck with two $450 paperweights, I contacted Mike Reagan to see if he knew of any sources.  He confirmed that the castings were changed and he learned the hard way that the Legacy truck frames are not interchangeable with the TMCC ones.  I'm not sure how far off they might be, but I was able to locate a couple from a forum member and never looked into it any further.

While mine are currently in good shape thanks to the new parts, I'm not fully convinced that they won't fall apart at some point in the future also, so I'd be interested in this project if it makes its way to completion just to have some spares.  I don't like the idea of being stuck with two beautiful but useless locomotives should the trucks fall apart again.

I have a silver one in a box and hadn't taken it out. Kind of scared. LOL

We will figure this out.  Bob Stevenson has a preliminary guess at $270 per locomotive, based on new molds.  But the molds themselves will be expensive; it will take 1/2 gallon of liquid rubber,and that stuff is $230 per gallon!

I am trying to get my hands on a Legacy part.  I will know more on that early next week - or if you have a connection with Mike, see if he could send a casting?  If they modified it, perhaps we could modify it back?

Let me get a few photos posted - one idea is to use Wolfer truck sides and the Lionel tongue and bolster. For that, all I would need is a "bowed, but not crumbling" casting.

And photos.  Note the interface of castings on the Wolfer part.  Also note that the wheelbase and overall lengths are identical, although the Wolfer casting seems beefier.  The interior space is identical, which says to me that one can simply put Wolfer trucks under a JLC GG1 and be done with it.  The  reduced flexibility will be negligible, I think, but at least you would have a display model.

I am trying not to repeat myself - Bob's idea is to split the casting down the middle, cast the brass in two parts, and then solder and paint(!).  He would need to do one set to really nail down the price.  My thought is that the Wolfer sides could be mated to the Lionel ends - I think I am repeating myself - to reduce initial mold costs.

Herewith (and wow! to the programmers who set up the enhancement routines):

Bob, I know curiosity killed the cat, .....it looks like as you mentioned, the Wolfer castings could be used almost as is with a couple of brackets made from sheet metal to mount it to the power truck, then it’s just a matter of mounting the pilot truck to the Wolfer casting....and figuring out the  couplers .....being that the Wolfer casting already exists,  what might the cost be to just produce the Wolfer casting and just adapt to the Lionel .......thanks for looking into all of this! .....you’ve done a lot already!............Pat

I'm the one who started this whole thing and I am in for THREE sets.

I am hoping they will be a bolt-on with no machining required.

I can paint them myself.

That would be best.

If you adapted the Wolfer truck in its entirety I suggest that you make the GG1 a display item.  I will get a price for that option.  Some assembly required.

The neat thing is, you may have a choice!

But let's wait and see if we can un- modify a Legacy truck.

Very cool, thanks for looking into this!

Heard from Dean Brasseur again.  I had asked to buy a Legacy part to see if it could be modified back.  Here is his response:

I am sorry, the Vision truck sides will not fit on these.

So, Lionel is not your solution.  They have in effect washed their hands of this, but have no heartburn with us copying the JLC part.

Next step: I need to get my mitts on one of these castings that can be cut.  One that is warping slightly but not crumbling would be best.  Bob Stevenson is ready to make molds and do a "proof of concept" cast.

Nobody volunteered a bowed casting for a trial run.  I will be returning Robert's perfect casting this week.  I still stand ready to help - I suppose Summer barbeque and boating have stolen our enthusiasm?

You know where I can be found.

I’ve tried to stir up one for you Bob.....I couldn’t get my hands on one...🙄......did you ever find out about the cost of the existing Wolfer/ Duddy castings ?........thanks ...................Pat

I only have a perfect one, and both of the people that I know that we'd like to get them for have castings that are already in pieces, I figured that wasn't going to solve the problem.  I don't have any interest in taking apart my perfect one to have castings cut up for molding, so unless another one surfaces for me, I don't know how I can help.

About 2 weeks ago I sent a pristine part for bob2 to use for a mold to make the new Power Truck Side Frame with Pilot but he decided that the part was too perfect to be cut up for a mold to be made.  I was willing to sacrifice a perfectly good part so that new parts could be made that would benefit a whole bunch of people.  Surely someone has a bowed but complete part that they can send to move this project forward.  Someone else needs to "step-up" as I did or there's gonna be more "shelf queens" in the future!

I know this would be a silly question........ but in this day and age would a 3-D cad drawing not exist on Lionel's engineering Dept. Server....... If so they could easily create a STL file and upload it to a 3-D printing service like Shapeways and sell outdated parts in that manor, But what do I know I am only a tool & die designer by trade and have been working with 3-D cad software or almost 20 years.

Mike - you are way out of my league.  I only know lost wax, and even then only enough to get somebody else to do the investment and pour metal.  Cutting Bob's perfect casting was not even discussed - we agreed I would return it intact.  It would kill me to cut it, then find out that the entire process would be too expensive to be viable.  I have not yet packed it for shipment - I will wait until next week.

No word on the cost of the complete Wolfer truck cost.  I don't want to become a pest.  Bob Stevenson is ready to make molds and cast the first set of the Lionel part.  We have not finished our discussion on two piece vs. four piece.  He is the expert, but I foresee problems with the two piece approach.

But hey - if the state of the art is such that a 3D printer can duplicate this casting in wax, that is a non-destructive approach, and we can surely cast that in one piece in brass or bronze, with very little shrinkage.  If Mike can stick a good casting in the bowels of such a printer and deliver a wax or plastic copy for, say, $50 each, we are still in the ballpark.

The 3D printing option that Mike is stating is very interesting.  BOB2, since you have had direct contact with Dean Brasseur, could you ask him about Lionel sharing the CAD drawing of the truck?  Even flat black, replacement plastic trucks from more than a few feet away may look and work just fine.

Bob, I'd love to see you succeed in this process. I've looked for a truck, but no luck.

Two things,

1. Why can't ya'll make a casting of the entire piece with out cutting ?

2. Order the vision line truck and cut and modify it to work.

Good Luck,

Ron Howard

If you can get someone to make a 3D scan of your good truck, then there's no reason why you cant get it 3D printed. 

I have bought brass parts from the Ways of Shape. They print it in wax then cast it in brass. The natural finish is quite good, without any printing lines/waves.

The big step is going to be getting the high quality scan of the part into a computer. 

Again, I am not an expert in lost wax.  I have limited pleasant experience getting such things done.  True experts have told me it is better to do this in pieces.

I have zero expertise in 3D printing.  If you go that way, I simply cannot help.

As far as Mr. Brasseur is concerned, I have had two contacts with him.  One, he gave me implicit permission to duplicate this casting, and two, he unequivocally indicated that Lionel does not want the Legacy part evaluated for modification.  I have no working relationship with him - he seems like a nice guy, so if and when you decide to go the 3D printer route, have someone who knows the topic contact him.  If you do print a one-piece wax, I am sure I can help get it cast in brass or bronze.  Have the printer increase the size by one half of one percent, to account for metal shrinkage upon cooling.

So, question?  Assuming someone can get this thing coded in some machine language for printing in a 3D printer, what is a good guess for cost each part in wax?

I am not an expert in 3D printing either, but check out these HO GG1 3D parts that I just found:

Foundry was just asking about you guys.  He is ready to do the first set at his expense!  All he needs is that cuttable casting - the one that is slightly bowed, but not crumbling?

I told him your ardor may have cooled a bit.  I was ready to invest, as was one other of your fellow forumites.  This makes it a no risk deal!  He of course would recover his initial cost on the subsequent sales.

Still no price on the Wolfer casting sets.  That would be your fallback if all else fails.

I wonder why we have not heard from a hobbyist with a JLC and a Legacy model?  Could it possibly be that one could just completely replace the mechanism?  Or is Lionel not interested in that either?

Is the zinc pest problem only the motor truck section or is it also the pilot assembly, which is screwed onto the motor truck section. Is the lead truck zinc pest infected too?  Harry 

Harry, if you check with Walt, he has an example.  It's the side frames that cover the power trucks and also hold the pilot trucks and couplers.  The other parts seem unaffected in the afflicted locomotives.

My question is that the section that is the pilot and holds the truck on can be unscrewed from the truck side frame. Does the zinc pest effect the whole unit has shown in the picture or just the big side frame section?  If we need the front pilot section also, I can probably cast this also. The airline ? up to the pilot I can not do in one piece attached to the truck side frame. This is a 12" mold just to do the truck side section. Harry 

I'd take a look at Walt's JLC GG-1 sideframes, you can see first hand what is failing.  I just looked at my JLC GG-1, and that entire piece in the pictures is a single casting.  I don't think the small pilot truck mount is affected, but since mine isn't falling apart, I can't be sure.  I'm not sure what the "airline" is.

I was this close to "signing out" on this project, due to a lack of enthusiasm.  Robert and I now have a collective investment of thirty bucks (shipping is no longer cheap) and I have no personal interest in that the only way I will ever own a JLC GG1 is if one arrives free.

But I see there is still life here.  If Harry wants to do the molds and cast these things, that would be ok - nobody will get rich on this project.  But we really should coordinate!  

Robert may have a bowed casting.  If so, we will saw it carefully into two or four pieces, and then get Harry and Bob Stevenson on the same page so we only do this once.

Yes, it is my impression that only the main casting is failing.  The "air line" as I recall is a separate piece, and will need to be moved to the new casting when the pilot casting is attached.

Although I have no stake in this project, I find this thread very interesting, the efforts being made here very admirable, and sincerely hope it works out for all involved. Best of luck.

The mold is in progress to make the big side frame section for the motor truck. I will see how this works out . I had 2 complete units to make the molds from. I will not need anymore ( I hope ). I will keep everybody posted here on progress.  Harry 

Cool Harry, what process are you using for the molding?

Harry,

 It’s great to hear that you’re going forward with this project.  I’m the guy who originally sent the “pristine” part to Bob2 because I have a JLC GG1 that is infested with zinc pest and I was at the point that I believed that this project needed to get done because there was no other alternative at the time.  I’m sure there are many folks with JLC GG1’s that don’t know about this issue and when they finally discover they have a crumbling truck frame and there are no parts available, they certainly will not be happy.

 I’m confident that you have this project well under control, however if there is anything can do to help bring this much needed part to completion, please let me know!  Again, thank you for your involvement.

 Chief Bob (Retired)  

This is good news!  Please post photos of the completed project.  I will notify Stevenson that we won't need to proceed.

Would it be wise to wait to see if this alternate plan works out first?

I think you are right, enough said for now. I will hopefully have a sample in a few weeks. Harry

When my parts failed, it seemed to just be the main part of the side frames that failed.  The pivoting pilot part mounted to the front of it was sold as part of the whole assembly, so I changed everything.  I don't believe the pilot itself had issues though.  I did re-use the pilot trucks as well since they still looked fine.

Yesterday, I contacted a friend who has two JLCs and told him about this problem. He has 4916 and 4925; upon being removed from the box, he told me that both seem to be nice and straight with no apparent problems. One is brunswick green/broad stripe, the other is tuscan/broad stripe, I just do not remember which one is what number. Good for him, I hope that they stay that way.

Jake,

        That is the same info. that I have been receiving from other owners. I am sitting tight waiting to hear from my  "SCIENCE PROFESSOR".

On another note, we just finished the mold for McCoy standard gauge steam chests. A sample has been cast from a zinc pest casting which we ground, filled w/ epoxy and reshaped. I need to drill, tap, mount the new cylinders & see how it all fits. I just realized that the cylinder mounting plate is also suffering from zinc pest. It was a casting, nickel plated. I can make out of steel and get plated as I go.  We are not the fastest train, but we eventually " arrive at the station "   Harry

I look forward to hopefully positive results.  I'm not 100% confident in my replacement parts that I was able to acquire at a premium, so new pieces would bring some peace of mind about owning two of the locomotives that have had the problem.

Harry - nickel plate?  Do you have the capability to plate an entire locomotive?

BOB2,

         We have our parts  nickel plated where needed,  generally in lots as a fixed price for the lot. We use a method known as 'barrel plating'.  I normally wait for a batch of wheel rim stampings, grab rails couplers etc. to run as a unit to keep the piece price down. This limits me to 2 - 3 batches a year.  I do NOT do this myself. Nickel plating a loco. is a different job, A LOT more expensive I would believe. I had contacted several plating shops in NJ for prices on plating our wheel rims. They all averaged between $1.80 - $2.00 a rim if I had 1000 pieces or more individually plated.  So you can see a loco. would be super expensive. Price ?. I guess $200 - $300     Harry 

Harry, go back to the original thread.

Here is a link to the original thread in O-27:

https://ogrforum.ogaugerr.com/...-sideframes-zinc-rot

I posted pictures of the only part that needs replacing.  All the other parts are attached to the failing part.  No need to try and make everything.  A one-piece casting of the failing part, on the right above, should be all that's required.

I have the green 4925, so far I see no sign of any issues.  I actually put it in the foam cradle and poked and prodded everywhere after the inspection, but so far those castings seems solid.  I hope it remains that way!

My thinking is that if they are still good now, they will stay good. Since so many have turned out bad, they went bad quickly.

I'd be careful with the 4925 model.  That's the same one I have that had the issue.  When my NIB 4866 silver model showed up with destroyed trucks due to the zinc rot, I checked my 4925 on the shelf and it was cracking badly around the screw holes as well which is something I hadn't noticed previously.  If the new parts work out, you guys may want to buy a spare set to keep around just in case.

If the new brass sideframes for the GG1 come to fruition, is there any way the same process could be done for a sideframe replacement for the Williams/Bachmann O scale Peter Witt car? On the surface at least, it looks like these suffered almost complete sideframe failure as well, perhaps even to a worse extent than the Lionel GG1, although they were not nearly as expensive. A shame, because they were quite a nice model otherwise.

It could, but last I checked the truck frames for the Peter Witt cars are still available and its probably more cost effective to just buy replacements from Bachmann.  They would likely be easier to reproduce though.

I would contact QCar Co, they deal in trucks and sideframes.

Brass copies of standard size truck side frames are trivial for a good foundry.

The sideframes for the Williams Peter Witt are an assembly consisting of the two sideframes cast together with the bottom half of the truck, and Bachmann doesn’t list them in their parts list, they only show complete trucks which are listed as “sold out”. Besides, replacing them with like parts would only mean that the factory replacements will also crumble from “zinc pest” as well. Someone here mentioned Q-car, but their sideframes are separate pieces, not cast as a unit together with the bottom half of the truck in one piece.

Bill in FtL

I would't care if they were cast in aluminum its cheaper and being thicker it will have some weight. Aluminum wont deform like the original, that every one is talking about.

Hi All,

   Hope this project succeeds, so my silver 4966 may run again.  Presently a hanger queen sitting on the shelf.  Any word on where the project is currently at?

David, Harry is working on it, but he has a lot of balls in the air, so results will be somewhat slow in coming.  He does have the contacts to get the job done, hopefully we'll see these at some point in the near future.

So is the thought that if they are currently good, they probably won't rot?

Hope may be a better word.

1st samples are beautiful, BUT, too much shrinkage. We will be modifying the castings to make a new mold.  Mold man says why would you work for $5 an hour?  "JUST BECAUSE".  Harry 

Great to hear of progress Harry, that was pretty fast!   How much trouble is it to adjust the size of the castings.

I am looking forward to getting my hangar queens on the high rail. Great work Harry!

I take it you tried the non-shrinking mold material?  You still get a half percent shrink,but that is way better than 4 1/2%.

Great news, we may all be back in business again.

Any news on this project?

Patience Grasshopper, Harry's working on it.

Looking forward to a solution.  Mine frames shattered as I worked to reinforce them with epoxy.

I will not be working on the repro truck frames now until after the holidays. One of my sons has a medical issue that has slowed me down, and we just lost our zinc caster for the wheels. My injection molder has also moved.  The GG-1 part is taking a back seat for now.  Sorry.  Harry 

Sorry to hear that Harry.  Best to your family and especially your son for improved health.  After reading this thread I really need to get my JLC GG1 out of the box as it's been boxed for the last 3 years. 

We of course patiently await your return to this project.  No hurry on our part.

Prayers sent for your son, Harry...

Harry III is doing much better, he still has one thing they have to "fix" early next year.  He got very lucky, it didn't sound good when I first heard about his issue!

Any progress on getting these replacements made?   Thanks in advance for any replies!  

It's still being worked, the second set of castings were close, but not perfect.  As Harry stated, lots of things have conspired to slow down progress.  The project hasn't been abandoned, we're still hoping to see a finished frame sometime soon.

Soon?

Well, "soon" is a flexible term.

The GG-1 truck frames:

We have re-visited the truck frame production logistics. 1st. I do  have a set cast in  plastic ,  in a  resin mold by my 'science' worker.  We have trimmed out and mounted on a GG-1 and lo & behold it appears to be working smoothly. The trucks are mounted , but have NOT pulled a string of cars yet. I expect to put thru that job this weekend.  My problem is, and I want your in-put on this, good or bad!!  Would you guys accept a plastic type frame?  What would be $ practical.   I already have over $1K into this w/ the original Pewter castings & mold. Now we have another  new mold, vacumn chamber, pump etc. tied up into the plastic production.   I am thinking realistically about $100.00 a pair.     My 'science' employee works part time, 1 day a week, &  we are able to pour and trim only one pr. in the course of a day.  That is only 4 pair a month.    Your thoughts please.  Harry 

I wouldn't mind plastic. Cast metal for a $100 is a great price or is this the plastic cost?

This is a 'state of the art ' plastic, very tough type. Harry 

I'd be willing to pay as much as $200 for replacement frames. 

Harry the price for plastic would be about $100?

And I know a retailer who has two or three affected JLC GG-1's in for repair where zinc rot is one problem to sort. I don't know what they might pay and I certainly don't speak on their behalf, but I suspect if they can offer a solution to their customers they may order enough to fix the ones currently in house and pass along the cost.

Plastic is fine. $100 a pair is acceptable. I need several pairs.

I am in for $100 approx price for plastic

Yes. $100.00 for a pair.  Harry 

Here is a picture of a Lionel GG1 JLC with a pair of our new truck frames. We will be putting them through their paces over the next week. So far they look great and nothing seems to be binding. 

HENNING'S TRAINS

That's really cool, I have to take a peek at those next time I'm in.  Is that Walt's GG-1?  If so, I'll bet he's glad to see it looking like that!

Harry,

When you say $100 per pair, does that “pair” mean pair of sideframes (enough for one truck), or does it mean pair of trucks (enough for one loco)?

Bill

One truck does both sides, it's one piece.  The quoted price is for one locomotive.

Very interested in this.

I'd pay $150 for metal, if that were an option. 

Dave

I have at least three that need help.

I'm in for a $100 plastic pair.  

However, is there any hope a brass pair might still get developed?  Metal would be my preferred replacement. 

I've been in for three pair since I started this whole thread. Here's hoping and here's also a big thanks for doing this.

I have one of these for sale if anyone is interested. I took it out of the box once and it had the truck issue as we know. I am giving up on doing the fix. Make a reasonable offer and its yours. Thx

While my 2 engines currently seem OK (knock wood!), I'd probably be interested in a pair (maybe even 2 pair to cover the bases for both engines) as a backup in case one of them decides to start crumbling one day.  (you know, buy the part when it's available, not look for it after it's not available when you are more desperate for it )

Of course with the limited production numbers described, I would not try to buy one before all the folks with truly crumbled trucks get a chance to buy theirs.  At 4 sets per month, I'm assuming there is enough demand that could take years to fill.  While I personally seem lucky so far with mine, there seem to be far more people who have not been when they opened their boxes after years of storage.

But if the production can be ramped up, I'd go for at least one set at $100.  From the picture, those look really good.  Hopefully if it is established that there is enough interest the processes can be learned by more than just that one science person to make these.

-Dave

My thought's?  Not on price or material... I had known of the problem from the first report, and possibly that a group was working on a solution.  Then for forgotten reasons, I'd concentrated on other things.  Now, less than a week ago, I made a rare foray into "3-rail Scale" looking to find any concern about curve easements-- I had discovered that 21" Lionel passenger cars (O-54" capable so labelled) could actually be towed around the 39+" diameter of 0-27 style 42" curves.  By towed, I refer the fixed coupler on the rear of a postwar F3A-B set, and proved it on the family room rug with a few pieces of track and a B-unit.  (Watch this forum...)

So I saw the set of posts here ending in a great silence in June of 2018, and realized whatever else had happened (new thread?) I must have surely missed the boat.  Tonight, I noticed the old thread title in the sidebar-- turned out the boat had not left and I was only 12 hours in learning that.  As we used to say in the engineering office-- if you can't be good, it sure helps to be lucky.

So, it is easy to say that $100 for a pair, for my one engine, looks like a really good solution to me.  It's been run, just to make sure it did. and one pantograph locked in a position just not touching (5-1/8"?) at the generally agreed best pantograph height of 5-1/4" (21 scale feet).  The PRR usual height is 22 feet.  Since then it has been under its display cover (compresses the pantograph slightly, there being about 1/4" spring  play below locked position) about 7 feet off the 1st floor of the house.  Here the thermostat is set for 78-degrees cooling, 68 degrees heating, less of both at night.  Humidity is higher in summer-- don't recall the figures, but cellar temps were about 5 degrees less, and 2d floor at least 5 degrees more, which would modify the humidity accordingly.  Right now, AC not run today (but yesterday) indoor !st floor is 70F and humidity 60%. My TMCC GG1 (tuscan) is not showing any disintegration, but it is hard to get a close look at it for lesser damage.

This GG1 has been my favorite among the several choices, because of its correct scale length, height, and correct shape of the shell.  I was actually able to see that its overhangs on curves required only 1/2" added clearance per degree of curvature, rather than the usual 1".  The model does require the usual 1", but that is because the frame being replaced carries the pivot point of the drivers, while in the model the pivot point is of necessity located at the maintenance-free motor. 

I would be interested in the test of how the new frame works pulling cars, but since I am beginning to see that my compressed PRR mainline layout could use compression of train length, I would get your frame regardless.  (I'm going to compress the 4-track main line to two tracks-- there is actually a long stretch of this on the NYC-DC route.)  Finally, thanks for all the effort you put into this.  --Frank M

I will be in for 2 pairs no problem.  Just say where and when you need the funds.  Love to get my two congressional GG1’s going:

When and where can we start to order the metal or plastic type frames?

Really appreciate your efforts Harry. I prefer metal. If plastic is the only option, then plastic will do. How much longer to complete the project in metal?

I agree with the last comment in that I'd prefer a metal truck frame, but plastic would work if it's what's available and proves itself to be sturdy enough in your testing.  A plastic truck frame beats the heck out of an expensive paperweight.

I just looked over one of the plastic frames at the shop.  Conveniently, they're molded in black, so you don't have to paint them.  The plastic "seems" pretty solid, the pull test will be the proof I guess.  The GG-1 runs fine with them, that's the first hurdle.
