Re: Internal groove?
Yes! I've drooled over a couple of "small" planers, but they're considerably larger than a small shaper. Not nearly enough room in my shop, so gave up on that idea.? Bill in OKC? William R. Meyers,

Re: Internal groove?
I've seen a table saw used to cut aluminum for motor mounts for McCullough chainsaw motors for my uncles racing go-karts. Not seen steel cut that way. Think the table saw would run too fast for that

Re: Triangular Gib Key For Unimat Vertical Column
What is the shape of the desired grove? Is it a triangle? If the use of a mill is available, then I would use a 45 Deg dovetail end mill to cut the grove in the column. Lay and clamp the column on

Yes.? Shapers were once pretty common.? The production drawback was the time wasted on the back stroke which, of course, does no cutting.? They are designed (usually a straight mechanical design

Re: Internal groove?
Long-stroke metal shaper. I've got a 10" Lewis shaper, and that would be too short, I think. Close, anyway. Grabbed my milling column for the DB200, and it's 11-1/4", or about 286mm. The collar is

I had seen more than once examples of making a keyway using a lathe like a shaper.? By traversing the carriage back and forth manually. Found this video showing exactly that.

Re: Internal groove?
Thanks Richard, and for the link. The page on ¡®Involute Broaches¡¯ shows some tooling of triangular section, looks like that is likely. Back and forth I guess, with a constant downward pressure.

Re: Two questions on manual thread cutting on Unimat 3
Hello: You're welcome. Yes, of course it is feasible. If I could do it, you can too. But it is not enough. I may have not properly explained this problem some / many (?) U3s have, so I'll try again.
