Making Simple QC Tool Holders
black85vette:
I liked the links to the Rolls and other designs but I guess the thing I like about the original post is that without a top handle it does allow a quick change. I had also wondered about the flange because I have the T slot on mine too.
The idea of two holders in a 2.5" square makes a lot of sense to me.
Russell: nice collection of tool holders. Looks like a SERIOUS wrench to go with it.
How about making one of the tool holders to take a tangential cutter instead of a tangential holder mounted in a QCTP holder? Just an idea.

RussellT, Nice!! I was planning on boring bar and cutoff tool "specials." And I particularly like the wrench.
re. welded on JT-33 stud (for a Jacobs chuck). I don't want to use that one for anything else. That's what makes it "Quick Change!"

The wrench was a bit of an afterthought. I wanted to try it so I tightened it up using a couple of short tommy bars - but it moved. I suppose I could have fastened the flange/washer to the post and keyed the washer so it wouldn't rotate in the T slot. Instead I just did it up tight. :D :D :D

I finally gave up on a good finish with the carbide, since even it was eroding from the mill scale. I finally just used it to scrape off the scale, ignored the deep grooves it was making, and decided to give all the blocks a final dressing with an HSS tool bit. That went better.
What a bunch of abrasive crud! Next time the scale is removed first before any machining -- thanks for the tip PhilF -- I'll look for brick cleaner. I think muriatic acid is available as such also in our local hardware store.
After the blocks were cleaned up, I placed one in the 4 jaw to center it. I marked all the blocks on one corner as a reference when placing them in the chuck. I opened only jaws 1 and 4, and the marked corner of the blocks all went against jaws 2 and 3.
The first block was centered in relation to the tailstock center, and then I replaced the center with a Jacobs chuck to start drilling for the post hole.

Drilling the pilot hole. All pieces were drilled at each step before changing the drill bit to a larger size. The finish size of the hole was to be 1.25".
