Group Subject

Is this group for ride on steam locomotives only or is it appropriate to discuss small stationary models no bigger than a shoebox.

My father had a small hobby shop, boats, IC airplanes U control and RC and he was know around town for electric trains. In the shop was a small lathe, as large as a jeveler but built as a model of a more classic lathe, about 3"x6". Lots of fun turning cannons but had problem finding tool steel so I ...

Re. clarifications on problems using SiC on Steel. Harold, your answer is the kind of deep dive insight you do not find easily. After digesting you explanations, I can relate now. I do get a nice polish, but it does feel like there is more rubbing than grinding, particularly if dressing was not fres...

Good post, thanks. Harold, you mention that Si Carbide is not suitable for ferrous because the SiC dissolve in the steel at high temperature. What happen then? What about using Sic for a final touch up where hardly any heat is generated. I usually rough my HSS with a SiO weel and then give a mirror ...

Reply to Steaming10 I did not imply that TIG is easier then gas, is actually more difficult than my original plan to use gas for brazing. I am a little concerned with having tanks, valves, regulators and hoses in a residential garage, a case of cold feet. I am more comfortable with a piece of electr...

Thanks to all, very helpful pointers. It all started after reading "Machine Shop Secrets", at one point the author states that a small MAPP torch is fine for most "small" shop jobs. I have one of those and got me interested. May be I can do more than sweating 3/4" copper pipes. To paraphrase a forme...

Thank you guys. I will check out the supply houses. Bill can you be a little more specific regarding the British boiler books? Where can you order them? I want to be able to braze steel to steel or steel to brass, something like two 1/2" square bars, 3-4" long to form an L for example. I do not know...

Help with Brazing

Forgive me for posting here instead on the welding group but there is so little activity there. I want to learn to Silver Braze small parts with a propane or MAPP gas torch. If I knew what I was doing I could buy all the supply on-line but I rather patronize a local welding supply that can add some ...
