The Home Machinist!

10 years ago I did a 1911 from an unmachined raw stainless frame. It took two starts over several months to get it done and together. Certainly not a project for just anyone. It ended up being one of those things I just had to do. Got a few more frames that might get done someday. A real sense of ac...

some years back one of our local pawn shops got in a large lot of mainly Starrett stuff. I got to look thru it but the pawn shop had decided to list it all on fleabay. They were delusional they would get close to new price for everything. For years going to live auctions and sales I had found that e...

I built a large static add a phase to run a 7 1/2 hp motor on one of my bigger lathes but then got a 10hp motor and converted the static to run the10hp as a rotary add a phase. While not true three phase, going to the rotary setup is far superior to just a static unit. I have put a few VFD's on othe...

Can you reach inside the smokebox with a right angle drill and make your holes

I have made long thin HSS tools that I could get behind the wheel in the lathe and trim the axle behind the wheel down to the size that the wheel needs to move back alittle more. Once you have clearance go to the press and give it a push right around the center of the wheel. If they are cast wheels ...

3/8" Penberthy injectors are still available.

This I already know

Do you think you will be doing an injector bigger than the 1/4" size. Between larger locomotives, steam tractors, and other steam driving things I think there would be a decent market for a 3/8 and maybe 1/2".

If its a single phase motor you could be having the start switch sticking once in a while. The start windings draw a good bit of amperage that is NOT included in your motor nameplate ratings. It could also be a start winding beginning to fail. The high inrush and large magnetic fields can jiggle and...

My first guess would be that the expansion due to the heat from the steam is causing it to bind up somewhere. Was it technically made for steam or just a model of a steam turbine? Expanding steam can get a turbine spinning real fast, this being brass makes me wonder if it was ever intended to be pow...

This is the first I had heard of his passing. There was talk about some of his equipment being for sale of recent but no explanation of why. Lee Wright was a good friend of Marks and he built quite a bit of Marks equipment and helped on building his railroad. Hopefully someone will come along with m...

If you have a mill I would set up the piece and indicate it in and then center drill, repeat other end.
Or if you have a collet set up there is always using a square collet.

I have always followed the rule that if you have a 5/16 injector, run 3/8 lines up to the injector. 1/4 injector go 5/16 lines. The larger the water supply lines the less effort it takes the injector to draw water in.
