When my current 1" gauge 2-4-0 is finished...the 7.25 loco goes on sale. Cannot justify keeping an extra vehicle to transport the bigger loco.

The 1" comes apart into two pieces weighing about 70# each and can be loaded into my subaru.
1" gauge??

Re: how to design an axle pump in 3/4 scale

Yes, the pump I posted is a little strange, but, it works quite well. It is not really a single acting or double acting pump. It is more like a 1-1/2 acting pump! The piston delivers more water in one direction than the other. When the piston moves to the right, some of the water recirculates to the...

Re: how to design an axle pump in 3/4 scale

Here's a drawing for the axle pump for my loco. It has a 5" boiler. 4-3/8 wheels, 1-3/8" cylinders with 2-1/8 stroke. My boiler is a bit shorter, but, I am pretty sure this pump would do the job. It is not a single acting or double acting pump, more like a 1 and 1/2 pump if you look at the drawing c...

Re: Silver soldering set up

On a related note, Builder01 mentioned heating only the copper, which I agree with. However it can Become annealed, and turn soft... i recently solder up some 45* copper pipe fittings to form a 90* angle. The fittings became annealed and very soft. Collapsed when I tried to install. In these cases,...

I find the black flux works better for me than the white stuff. The former seems to have a greater temperature range.
Yes, I have used both black and white flux. The black certainly has longer life for high temperatures. I use it exclusively. It's available on Ebay.

Re: Silver soldering set up

Vinegar is actually made of acetic acid, not to be confused with citric acid. Citric acid is purchased usually as a powder and is mixed with water. It is a bit more aggressive than vinegar and yet it still quite user friendly. I scrub my parts with a brass brush to get the last bits of oxidation off...

Re: Silver soldering set up

If you are just doing cone fittings on copper pipe, a small propane torch will give you enough heat. Put flux on both the pipe end and the inside of the cone. Push the cone onto the pipe. The fitting should not be too tight of a fit on the pipe, you want a little space for the silver solder. Play th...

Re: Covid Creations

I made a pair of "locomotive jacks" from scrap around my shop. Sometimes I need to lift my loco just a fraction of an inch for testing on compressed air or steam. These work great and are very stable.
