开云体育Hi Gang: I think this tapper takes rubber flex collets. I don't see any included, but I'm sure you could make substitute collets. Even with
shipping, not a bad price, if the bid doesn't go too high. Carl. On 12/14/2024 12:35 PM, Richard Burrows

Re: Triangular Gib Key For Unimat Vertical Column
You're still going to need a relatively large milling machine. The table on my mini-mill is just over 15" long, and I'm not at all sure how close you can get to the ends. I got to use several Bridgeport clones with tables around 50" in my class, and it would have been a snap to do it on one of those. The post I have does have a feature that would help index it, though. That would allow moving it down the table to make multiple cuts if necessary. Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

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 it's side and cut on the forward face of the column, not the top!! Use the X to cut the length and the Y to cut the depth.

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.

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 but a hydraulic scheme came later) so the backstroke is faster than the cut stroke to help at least a little bit. Since this group has a small machine focus, there have even been hobbyist sized shapers, notably by Adept in England (almost made a small lathe popular with hobbyists), that are hand powered.? You can see that here: A planer (for metal, not like a wood planer) is another machine some may not be aware of.? It is a cousin to the shaper, but typically larger, much larger, where the tool bit is stationary, and a long table holding the work piece moves to and fro. Charles E. "Chuck" Kinzer

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 in steel.? A slitting saw on a horizontal milling machine would likely work for rough stock removal. Could also work on a vertical mill. I've got one of each, if I can get farther into my project list, I may be able to find out. Also have some side milling cutters for the horizontal mill. And it may be closer to operational than the HF mini-mill. One of these days I need to buy a machine tools that's ready to run! ? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.)

Cutting a grove on the milling column, a couple of methods come to mind.? You could use a carbide blade on a table saw, lock the column so it couldn't rotate and make a couple shallow passes with the table saw.? ?Another way would be to use a key way cutter in a router on a router table and cut a grove that way, or use a dovetail cutter to cut a triangular grove in the milling column.? ?As for the head only a small depth would be needed and using a dremel with a diamond burr would be sufficient to hog off material, and finish with a file using it as a gouge to cut the square shape.?

There is a Tapmatic 70x Reversible Tapping Attachment #10-5/8 Capacity up for auction on shopgoodwill.com
This might be useful for someone who has a larger lathe, I have a DB200 so this is to big for mine.
Looks like it could be a morse taper 2...
