    Also make liberal use of the tool check macros. One broken drill or tap can turn into a whole turret of broken tools super fast, and the time it takes to check after each tool is done is...

    Those are for if you need to offset the tool. For example if you're running a saw in an arbor, you don't want to come down on the center of the arbor, you want to offset it to touch a tooth.

    Adjustable power supplies are pretty cheap, cheaper than a car battery, and may be useful to you anyway when you start resurrecting the control. The big advantage is they current limit if something...

    Basler and Flir would be the manufacturers I'd look at first if all you need is a dumb camera.

    No. Old things ARE. There is no "might be." If it was made before 1933, it is in the public domain, unless it is a trade secret like the formula for Coca Cola.

    Once a piece is old enough to be in the public domain, I can't see why it isn't fair game, as long as you're not trying to pass it off as the original. There's one resolute desk. There are so many...

    Woodmizer are a customer of mine. That makes them tops in my book!

    They've always been a stand-up company to me, and usually companies treat their customers better than their suppliers.

    Well, yes and no. If your seal is perfect, then I agree, eventually you'll get a nice vacuum everywhere under the part and it doesn't matter. But if you're cutting a little close to your gasket, or a...

    I think a non-trivial part of the difference is that softwood is traded on the commodities market and hardwood isn't.
