Re: Precision machinist

When I was in high school in the late 60's they were starting to phase out the shop classes then. I had to argue with the guidance counselor to let me take them since I was deemed to be in college prep, but I prevailed. They were what got me into a career of mechanical engineering and this great hob...

Re: Making a boiler without a lathe

The boiler should not be made from brass, use copper or bronze. The zinc in brass dissolves into the water over time and it becomes porous and weakens. Brass works for piping, tubing and external fittings, that can be easily replaced if they age out.

Re: Polishing inside of 0.25" cylinder?

I cut a slot with band saw in small diameter wood dowel and slip a small piece of rag in it. Put some brass polish on it and spin it with an electric drill as I push it and out of the hole.

Re: Regauging a 7 1/4" Minnie Project

It's a 2-4-2. The trailing wheels do not show up in the photos due to the width of the 2 1/2" scale cab. And yes it definitely needs the trailing wheels for balance. It would be a rocking horse with out them.

Re: Packing material

I used the graphite tape from McMaster Carr. It works fine. It dose not last as long as the graphite yarn packing. Fine for 1 1/2" scale packings. But the strands of yarn are easier to install in 3/4" scale..
