    It can't collapse if it stays round. Yeah, I know ... duh ...

    A friend of mine built an airplane from carbon fiber tubing. To prevent buckling, they glued 'biscuits' laminated from balsa and foam...

    Albrecht calls that a 'chuck', but it's a collet holder. They're a shallow taper, with limited grip range generally suitable only for endmills.

    I'm also in the collet whenever possible crowd. The...

    Mine seized up and destroyed the screw. And buggered the nut a bit. I had plans to rebuild it, and my spare, with an ACME screw, *AND*, convert them to decimal while I was at it. Found some 3/8-16...

    I planned that for my kf700, but never got around to it. Left off the half depth extension and sawed the fence rail off flush. Have never had a need for more than the 27" or so it leaves. And with...

    Are you trying to run it on 120? That's the only way I could see it needing 40A. The 40A range breaker should be a double pole at 240.

    I have a 3HP Oneida running on 240, off a 20A (I believe)...

    We have 2 from CNCRP. Both configured as 4 x 16. The newer one has the linear guides and the spindle they sell. Both huge improvements over the older one which has the v rollers and a router motor.

    Here's a chart on the relative potential of different materials rubbing together. Note wood and ABS are fairly close together, while PVC is way down the list which would seem to make it a far worse...

    We use the vc in a cnc router, don't know why. I consider them disposable.

    The 'right' way to do this is to provide an outside source of air for the router. IOW, a duct to the top of the router where it draws it's cooling air in. This would keep the chips and dust from...

    Mine tops out at 2500. No way I'll run it that fast with a chuck on it, no matter what the chuck is rated for. Collet chuck, sure.

    Depends on the chuck size of course, but 1000-1500 can be kind of...

    Probably so it bottoms (tops?) out on the o-rings on the shafts instead of the router hitting the top plate. Possible you could break the insert out if you jammed the router into it.

    Most of the time, you can get a tight v belt onto the edge of the pulley and run it back on by turning the wheel, like putting the chain back on your bicycle when you were a kid.

    Hotels are cheaper near the airport. Stay there, take the 'free' shuttle back and forth to the airport to get on MARTA. That's about the cheapest way I could think of. Just takes a bit of time...

    Mill? Like to trim the peened area off? Lay it down across the vise and mill it off. Could partially drill and tap before milling while you're at it. Holding the bare handle would be trickier, but...

    I get 15.834 angle, which gives a helix length of 11.429 and makes the paper effectively 3.119 wide. So 5.771 (18/3.119) wraps, plus another helix length of 11.429 to finish off the end = 77.387

    Standard reference for a straight line is a tensioned wire. Some thin steel wire, like maybe a guitar string, attached to a piece of wood with some way to tension it ... like maybe on a guitar ;-)
