    I disagree with this characterization of CAM software. They way you describe it is exactly backwards from how it really is.

    You start with a piece of stock and subtract from it with cuts to...

    I don't think anyone remembers passwords today, they use a password manager.

    I've been using keepass to keep my passwords safe for almost 10 years now. We started doing tiered passwords with...

    A dab of the ole high carbon hot-glue ought to keep those things going the way you want, no matter if it's forwards or backwards.

    I'd worry about re-engineering it when that bridge comes crossing.

    I was reading 7Kw motors and 1.5m on a side with NEMA34 steppers that have 0.0004 accuracy per full step and my brain exploded. I'm a quivering mess of jello now.

    But seriously, I know how big a...

    Methinks that Aligator lacing is too big for this belt. What size lacing did you get? How thick is the belt and how wide?

    Looks like you got conveyor lacing instead of belt lacing. They sell...

    Those high shear tools also generate a lot of upward pull when cutting. To get good results it's even more important to have a rigid setup. I have a Shear Hog and have used it on a variety of...

    Your original TPG insert looked like wiper inserts with a very large wiper interface. The theory is good, but application is questionable. I agree that you can salvage this cutter with some bog...

    Used machine tools are almost never in operation until the day they are sold. Someone make a conscious decision to separate themselves, and the first thing that gets neglected is the coolant.

    I agree, those Brothers use early 80's technology, 8086/8086 based. It's all through hole 5v stuff in the control, and the drives are custom discrete BLDC drives with resolver feedback. Unless...

    IIRC, Carvesmart has a patent on dovetailed jaws. I was skeptical of such a patent, perhaps someone challenged the patent and it was invalidated? Now Orange doesn't have to pay the Carvesmart tax...

    Hardinge CHNC lathes with the Siemens control would do that when the motor had issues. IIRC the wires to the encoder would break and it would go off yonder in a flash.

    I assumed the old shop was just a leased building that he didn't own. After the ins I assumed he bought some land somewhere. Maybe he bought the land under his old shop.
