Re: Lathe for turning wheels

The three phase requirement is easily met with a rotary phase converter, which is nothing more than a three phase motor started with a pony motor, or capacitors. With this setup, you'll get full power from the lathe motor. Static "phase converters" are not the solution, as they are nothing more than...

Truly a mind bending experience!
I agree. Susan and I had the good fortune to see it performed in Utah, many years ago.

Re: Speaker selection switch, and more than you wanted to know!

I had to chuckle when you said your system was overkill. Is there really such a thing? If I had means, I'd own one of McIntosh's 2,000 watts amps, although I have no idea what I'd do with the power. Thanks for your very welcome comments. H Well, you wouldn't have to worry about clipping! True, but ...

I wonder--is the engine fired with Char?

Re: Electrical wiring in the home shop.

Another thing just occurred to me I could tack the extraneous knockouts with a welder so they can't open and then drill wherever I want. That offers the opportunity to destroy the device. Not saying that it wouldn't work, but the knockout is generally offset (from the punching operation), so even i...

Re: Mill & Lathe: Where to Put Them?

Fact is, turning with or without a center can yield taper. That's the result of the bed of a lathe twisting. Lathes are leveled to remove twist . They need not be level to operate. You could set your lathe at an angle, and it would operate perfectly well, assuming it had no twist. H Are you saying ...

Re: Electrical wiring in the home shop.

Far as I know, the only big tool I have that has fuses built in is my lathe. Some of my tools are on VFD's and magnetic starters. I like to think there is some protection in there somewhere, but I don't actually know. Starters are generally amperage sensitive, and will trip when overloaded, so, yea...

Re: Driver machining order

I'd like to express a few random thoughts. Feel free to disregard, secure in the knowledge that I am anal about precision. Drilling holes isn't generally a precision operation. The spacing between the axle bore and the crank pin should be identical for all wheels, otherwise you can expect binding of...

Re: Mill & Lathe: Where to Put Them?

It also occurred to me that it could conceivably be useful at some point to use the mill table to support the end of a really long lathe workpiece. Careful! You're coming down with mental health! :wink: Anyway, here is my question. Should the mill back up in the corner, or should I have the table p...

Re: 1911 Project

I have always said that how one works is a good indicator of the degree of quality that will be achieved. The workmanship being shown here is amazing. Well done, Glenn, although I'm certainly not surprised.
