In case you are talking about spring steel (1095), or other materials in small quantities, I bought some of this on ebay at a very attractive price compared to getting it from MSC or McMaster. Only problem was, it came in 2" x 16" strips so there was more cutting required than if it was in a roll. W...

When a hss bit is cutting properly on the lathe, you will get a "frying bacon" sound. If you get a "rumbling" sound, it means the bit is dull or not set at the right height. And if it's screaming, it usually means that the setup isn't rigid enough, or the width of cut is too much for your lathe. Str...

Andy,
I have a lead on the original drawings and hopefully they will give details on the valve gear. Do you know which dimensions didn't work for Bruce and what he had to modify?

OK, that explains a lot. I think what I'm looking at is the style 5 frame with long travel because it is on a heavy mikado built in the teens (ICRR)
Thanks.
Now I need to figure out how the dang thing works!

Baker Valve Gear

Could someone please explain the difference between Baker valve gear style 5 frame and style 2? They look almost the same. http://www.railarchive.net/bakervalve/parts_14.htm http://www.railarchive.net/bakervalve/parts_60.htm I'm trying to figure out which was used on a particular prototype loco. Tha...

Collin, Static converters are fine as long as you don't overload the mill. At most you can get about 2/3 of the rated hp using a static converter. An alternative would be a rotary phase converter (RPC). You can get a lot of info on building your own RPC by googling "rotary phase converter". These ca...

Well, I expected a lot of ideas and you guys haven't disappointed me! A number of things I hadn't thought of like the square (OK, trapezoidial) ports and unrestricted supply/exhaust passages. I guess I have to confess that I'm after the sound and not the efficiency. If I wanted the maximum efficienc...

Designing for the "Big Chuff"

I've noticed that some locos have a very muted exhaust, and others have a very sharp, distinct exhaust sound. It's not directly related to the size of the loco, either. What design elements affect this? Is it valve design (lap, lead, clearance, etc.), boiler pressure, exhaust nozzle design, backpres...

Lone, I know nothing about this brand of lathe, but have a few comments. The ebay description is pretty specific about the motor; it says it is 3 phase. You can run such a motor on single-phase, but this requires a converter. If you only have 110 volt single phase, this will be a problem. The descri...
