Re: Lathe for turning wheels

Ryan, do you have the bottom half of the compound tool holder? A local guy here in Seattle has something that might fit. Let me know and I’ll ask him. It would be a freebie.

Cagney Electric Train Set

A fellow on Facebook has just posted the rarest Miniature train set in the world- an electric/mechanical Cagney amusement park loco. I’ve never seen photos of this before - indeed these photos maybe the only that exist! Apparently Cagney only made three of these, although they did advertise mechanic...

Re: Flat Car Plans

Very interesting that you plan to build your RR as a working road. Working roads often changes the dimension of what you do and how you build your equipment. One issue with gauge is there are some limits to how wide you can built with each different gauge. Build to wide a car and it tips over and sp...

Re: Flat Car Plans

Flat cars are pretty easy to free lance. All you really need are the general dimensions. Here’s a couple of construction photos for my 2.5” scale (12” ga) flat car build - based on a 40’ flat car this came out to 8’ x 32”. Same basic thing as 7.5” gauge. Just half again bigger. Note: in 7.5” ga, thi...

Re: Which pressure gauge to use?

Quick update on results of smoke box vacuum tests, using my home made manometer. I constructed the below seen nanometer last week and have made three trials with it thus far.

Re: Limited room for steam.

Some pictures and dimensions of your boiler would be helpful to assess possibilities for altering your steam dome and throttle valve. Generally boilers have a lot of froth and sloshing when steamed up to operating pressure. Eng. Porta, of the Argentine Railway’s Lempor exhaust system fame, described...

Re: Which pressure gauge to use?

Joss and Richard, thanks much for your input and suggestions. Looking forward to upgrading the Ottaway’s front end with a “state of the art” multi nozzle Lempor evaculator system. Apparently, Ottaway’s, as a standard class for amusement park locomotives, were originally not considered to be very eff...

Re: Which pressure gauge to use?

As Richard says, you can get draft into the smoke box from the top of the stack! I just tested my exhaust out the stack and found 1/3rd of my stack drawing air INTO the smoke box (blower offset a little) on the port side of my engine. I used a long strip of paper. The exhaust sucked the paper into t...

Re: Interrupted Cut Removes Tool Point

I often read about using soft jaws, yet I don’t have a clue what material to make them or the specific steps involved. Any good primers around someone can recommend?

Re: Possibility for a 2.5" scale dynamo

For 25 bucks you can’t go wrong! Buy it and see what happens... My guess is you won’t need a huge amount of steam to make this motor work. The led’s might work with just a wisp of steam turning the motor, less than 12 v perhaps. Start small and experiment, maybe with one or two 1/8” nozzles. You cou...

Re: Which pressure gauge to use?

Richard and Tristan, very interesting! Fascinating that your design works so well in pratice. Coincidentally, just finished reading the part of Koopmans book discussing double petticoats - and four nozzles- first implemented by Chapelon(?) on the French railways around 1928. Seems like your design c...

Re: Interrupted Cut Removes Tool Point

Iam thinking what Glenn said- and Harold also in the past has recommended taking roughing and finishing cuts on both sides to stress relieve your flat surfaces. I didn’t think that aluminimun would have the same kind of issues, as I don’t work with it much. Your expenerience is a great lesson. Glad ...
