I noticed on an other form a re-motoring of a Mi=Loco Hudson and as I have an interest in these and 17/64 scale I thought it might make a good threadScreen Shot 2015-05-13 at 9.41.22 am I purchased this one a couple of years, unfortunately this is what it did look like, it was smashed in the mail and i did'nt win this on the bay at the time, but the smashed and returned item did get relisted, its currently under repair, any one have a chassie??     (cTr....Choose the Right )

Come visit the March meet 3-18th  & 19th ... I'll have old school 17/64ths on display and a short run of outside 3rd rail..... always looking for new interesting pieces

http://www.marchmeet.net/

here is a video of my Scalecraft K4   17/64ths in action

https://www.youtube.com/watch?v=prwn04aGsIg

 

Below Min-I -Scale  /Congress Tool and Die  circa 1937  Hudson in 17 64ths 

IMG_1336

 

Scale Craft K4  first introduced 1934 ?  or 33?   built to 17/64ths ..but listed in flyer as 1/4" ... it towers over the Scalecraft or Lionel Hudson's  built to 1/4"

IMG_1477IMG_1485

 

In my humble opinion 17/64th's is the way to go for O gauge  ... as it is the correct scale for the track gauge ...

 

To quote Lee B Green  ( Mr 17/64ths)   " Make it Perfect or Don't Make it "

Screen Shot 2016-07-16 at 6.53.55 PMThanks Everyone its great to see people have an interest in Mi-Loco and Mi-I- Scale and 17/64 scale in general, I picked up some Mi-I-Scale passenger cars they might be the only ones in Australia, now Im going to be proved wrong!!!Screen Shot 2016-07-16 at 6.52.34 PM

Carey Im going out to measure, my ScaleCraft K4 you have me intrigued, I loved your video and just keep watching your Hudson go back and forth.    ( cTr....Choose the Right )

Here are few more ads etc from Mi-Loco and  Min-I -Scale

Cheers Carey

PS Any one who has a Lionel  City of Portland , Hiawatha , and the scale 0-6-0  also has 17/64ths  within your collection.    Did not you ever wonder why the Hiawatha looks down on the little 700E ?

Earliest ad for Mi-Loco  June 1935

Latest for Min-I-Scale  Nov 1938

 

This is based only on what I have found to date ... the window could be pushed out on both ends  with more research .

 

Cheers Carey

Really nice photos of the K5.  I am gong to light off the big computer and see if I can post a K5.  The one I did had aluminum superstructures, and cast iron main frame and drivers.  Elegant, when finished.

I believe these two were the major suppliers of 17/64 scale.  I note that both call it "17/64 Scale, O Gauge".  That is the way I have always heard it described.

Lionel did the UP Streamliner in 17/64, and about half the Adams Diesels are 17/64.  I believe the Williams PRR steam switchers were also 17/64.

Bob  I think my interest is nostalgic in nature, but that extra 5% in size is quite attractive. I think I would say that the mass of a locomotive and its rolling stock, in the real thing, is part of the attraction that leads to the hobby itself. So bigger is always better, but we all have our ATLANTIC 002restraints right ?ATLANTIC 005ATLANTIC 006 Here's a loco I bought  that I believe was built from this article and of course it is 17/64 scale as many of Mel Thornburghs articles where. Thanks to those who posted pictures of models other than Mi-Loco or Mi-n-Scale.    (cTr...Choose theRight )

Big computer - we shall see . . .

Big Cab Fwd

This is 17/64 scale, O Gauge. It is all brass except for cast iron drivers, and motor/gears.  It was my third attempt at scratchbuilding, and has won prizes.  Main frames are red art bronze castings from Lobaugh Challenger parts; tender truck side frames were cast from my masters by my father, who was teaching art casting in Tucson at the time.  Runs like a watch, fits the track, and has illuminated class lamps.

That is the first photo I have posted here since the format change.  Apparently the new format is not compatible with the iPad.  I discovered that I could snatch images from my files on this horrible Microsoft 10 computer when Photobucket became impossible to deal with, so now you again get to put up with my photos.  The MiLoco K5 is a print, so I shall have to get it scanned.

Bob   I never get tired of seeing images of your loco's and especially cab forwards. Don Beeman was another scratch builder like yourself that modelled to 17/64 scale. I remember a Pennsylvania T1 with a six wheel trailing truck like the Pennsylvania steam turbine. I wonder what happened to his scratch built loco's O! And he had modified and supper detailed Mi-n-scale passenger cars.      (cTr....Choose the Right)

Bob    It reminds me so much of the HO Round House loco I still have.

Carey     I made more measurements on the ScaleCraft K4, the boiler diameters are right on for 17/64 scale, if you lengthened the fire box 11mm at the cab end, and puled the cab back 4-5mm the whole thing is spot on 17/64th.  Its like ScaleCraft changed its mind on scales. The frame is 1/4 scale but the cylinders are okay for 17/64th.    ( cTr....Choose the Right )

Hello all 17/64th er's

Thank you for your kind words ... and ruler measuring the K4 ......

Clearly there was great confusion among the troops in the 30's  as to what was "O" scale .... 

the 1930's was a time of great public layouts  that attracted huge crowds ( the days before TV, and in the deep of the depression ) .   The real railroads seemed to have real money to throw around  creating these monster layouts to promote train travel ....and indirectly model trains .    Many of the early manufactures  both competed and worked together filling the various layouts with engines and rolling stock . 

Scale Craft .. had their K4's running at the Chicago World's Fair in 1933  at the Pennsylvania Railroad display...  re-motored by Icken for the  following years run .    So  17/64th's or very close to it  was running ...despite the Scale Craft flyer claiming  1/4" scale .   In 1934 when the  Scale Craft Hudson  was introduced  1/4" again was advertised ..but this time ( save the huge headlight ) close to 1/4" was modeled.  

 Fun to try and dig to find more information about these early days of discovery in the O scale world .

Here are a few photos of a Scale Craft K4  17/64ths  and a Scale Craft Hudson 1/4"   and a Min- I -Scale Hudson 17/64ths .

Ads from January 1938 ...  Hobby Shop offering both 17/64ths and 1/4" Hudson's ...also note the invasion of HO and OO gauges.... first signs of O scale slipping from the masses,  losing them to the little trains ...  

 

Notice the price difference ...O scale was big time expensive compared to  OO and HO.     AC Gilbert took  Josh Cowen to the laundry offering his HO  Hudson for half the price of the OO hudson

1939 lets review why few stayed with O scale

 

Ed Alexander, Hudson, custom built O scale  175.00 up

Lionel 700E 75.00

Min- I - Scale Hudson 70.00

Lionel  OO Hudson  25.00

AC Gilbert  HO Hudson   12.50

Probably the Europeans, but we do not build to 1:45 in the US as a rule.  We use 17/64 scale, which is ever so slightly smaller, and correct for O Scale track.

Most of us use Xerox machines now, which can be quite accurate. And hand-held calculators make conversions to rulers (scales in inches and tenths) quite easy.

Hello all you 17/64th ers

The March Meet was great ..with some new finds . 

Below are some photos of the Mi-loco  ( sand cast no rivets, aluminum  ) and Min-I-Scale  ( die-cast with rivets much finer detail, zmack  casting --think carburetor) .

Here with have the hopper and box cars (both 17/64ths )

 

 IMG_1687IMG_1688IMG_1689IMG_1690 

 

Also a line up of Scale Craft , Mi-Loco , and Alexander K4's .... Alexander is 1/4" scale ...others 17/64ths .

Cheers Carey

If it helps, that tender is a 1/4" scale import.  Sorry about the track; since re-gauged.

Garmin 002

This one is 17/64 scale, and is nothing more than two 0-6-0s and a lead truck.  Note that you cannot see the drive line - I am using an Escap motor to power two NWSL gearboxes.  No prototype, but similar to logging locomotives found near Mt. Shasta.  I also put together a 2-8-0, a Mogul, and a Ten-Wheeler using the same ideas as in that 1990s article.

I am delighted that you guys are continuing to feed this thread.  This sort of stuff is my major interest in the hobby, second only to my Lobaugh collection.

Hello all

I'd agree with Bob ..the Alexander is on the small size ...certainly compared to the Scalecraft and Mi-Loco's...  a much more delicate machine .....  and quite a bit lighter than the others ..hope it can pull a few of the Alexander cast coaches. 

Another find at the March Meet was a scratch built T1 .....it is big ..one of two found together .... so the builder must have really loved the design to  build a pair of them . Unknown history ...so if anyone out there in the world knows something about this early stream-liner , I'd be very grateful for the information.  Dual motors,  brass, sheet stock , some small castings ...I assume 3rd rail pick up when she  was young. ( judging by those holes between the front drivers), inner set of drivers sans flanges .   I does run ....  

Cheers Carey

Hello17/64th fans ..today we have a comparison of the Mi-Loco ( sand cast aluminum--sparse on detail ) with the Min-I-Scale (die cast Zemak ---these weigh a ton..but look great !....good detail ..count those rivets) ..passenger cars ..

Mi-Loco ... coach only ... separate steps 1935-6

Min-I-Scale  coach and combine ...steps cast with body panel 1937-8

Both companies use the basic 2 part body ... seam down center of roof, skeleton under frame and added truck bolsters.   

After you see one of these in the flesh you'd never consider placing a Madison car in the same room as your 700E again.

Darn shame 17/64th's did not win the race .

Cheers Carey

17/64 is 1:45 for all intents and purposes. It was just a way of using the more accurate German domestic market scale ratio for O gauge  by quoting it in an Imperial measurement by early US modellers.

Some modellers must have had some interesting fudge methods with such an awkward measurement. Pocket calculators were thin on the ground at the time :> The most likely  answer is the engineers amongst them would have done 1:45 on their slide rule.

I didn't release there where two different  manufacturing methods working on the rolling stock and passenger cars with Mi-loco and Mi-n-scale. The pictures tell a lot, my passenger cars are definitely Mi-n-scale but they are riveted on the roof just like your Mi-loco cars. The varations for such a short lived enterprise are surprising.   Here's one of my Hudsons its missing some original parts, they have been replaced with 1/4 scale parts. See if you can pick them!Screen Shot 2013-07-15 at 12.18.00 PMScreen Shot 2013-07-15 at 12.16.21 PM    Bob you have to be pleased when it runs first go, it looks terrific , I really have to finish some of my projects!!!!
