Re: 3/4" Scale J1e

Hello My Friends Got a bit more done on the Hudson cab today. The cab sides had some more rivet holes located and drilled. Then the cab roof got some attention. As stated earlier the cab roof has three sheets. The center sheet and two outer sheets. The outer sheets have a large radius over the top o...

Re: 3/4" Scale J1e

Hello My Friends Had a great time playing in the shop today. Spent the day on the cab, and I didn't break anything or hurt myself. :D Life is good! In our first snappy the front sheet has been marked out and center punched for the rivets that will join the front to the curved angle that the roof wil...

Re: 3/4" Scale J1e

Hello My Friends First off, thanks for contributing to the thread. I agree with you that dimensioning from drawings can have it's shortcomings. If I were making something with critical dimensions like valve gear parts this method would definitely not do. But here I'm just making a little bit of balo...

Re: 3/4" Scale J1e

Here is some more. In the top snappy here we have our work piece nicely flanged over. You will note that it's still attached to a large sheet. This is necessary when forming, as if it were a narrow piece, it would creep under the form dies when the forming is happening. Now it will be marked with th...

Re: 3/4" Scale J1e

Hello My Friends Thanks for the tip Bill. I have a computer and a scanner, and have done this that way, and in certain circumstances I still do. But I just like my pencil and dividers. To me it's just fun to do things the olde timey way, the way them old cats at American Locomotive might have done i...

Re: 3/4" Scale J1e

Hello My Friends I hope you are all well on this Fourth Of July. Things are fine here in the high mountain desert. Here is a little dodge that you may find useful. Sometimes we are presented with drawings or illustrations that have no dimensions. Illustrations of locomotive appliances are an example...

Re: 3/4" Scale J1e

Hello My Friends Making progress here, the waxes for the running board- air reservoir supports are at the foundry. Molds were made for a gaggle of goodies, the running board supports, the bell and yoke, the Franklin precision power reverse, and a few other little trinkets. The castings should be her...

Re: Nickel Plate 762

Hello My Friends The green material is masking tape. It is used as a temporary spacer to allow for the thickness of the paint. As you know a difference in diameter will change the circumference significantly. So if you don't use this tape dodge and paint the jacket on the inside the mounting holes i...

Re: Nickel Plate 762

Hello My Friends
The throat sheet and back head wrapper were made of 1/16" copper. Thinner material is actually more difficult to form compound curves as it wrinkles more easily. They also have to be drilled and tapped where the side sheets fasten on.

Re: Nickel Plate 762

Here is some more. In this top photo you can see two of the running board-air reservoir, piping brackets sticking up through the running board. The running boards are edged with 1/4"x1/4" tee section brass. The running board material is some tread material that Jim had photo engraved. The Third phot...
