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.

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!

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.

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.

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.

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
