The adjustable Tool Holder looks like the design I worked with the late Art Volz for shapers. I silver soldered the end on my unit.

That depression is to prevent a knot raising up when you bent the holder during the forging process.

OK, that makes sense. I'm trying to remember now whether or not the ones without the depression showed any grind marks in that area. Probably did...I can't really recall.

Very nice work Lane, and I enjoyed following your thread on the restoration of that shaper VERY much. Thanks so much for sharing !

I have that question also. I'm going to guess he used the shaper, if not then a square broach. How about it Lane?

No how about a drilled hole and some good square files. About 1 1/2 hours of file work on each hole.

That is some very nice file-work, those are some great looking holders.

I did a small square hardy hole through a RR track anvil and have no desire to replicate the experience, I plan on using these next time I need a square hole: http://www1.mscdirect.com/eCommerce/...g+Bar+Adapters

Probably cost less than the new files.

Lane,

Nice file work was an understatement, you must have the arms of a gorilla. Using a drilled hole and a file did occur to me but I soon dismissed that as a choice. I agree, nice (outstanding) file work.

The vice bins are a nice idea. Maybe we should have a Chip Control thread?

I am building a very small air compressor. Not sure if it will be a legit useful tool, but should work. I've only finished the cylinder bore and piston blank so there's not much to look at.

Re: Small compressor- ok, but we'll need some pics!!!

lane,

What is the reason for the depression on the top of the Armstrong style tool bit holders? I have seen that on some holders and not on others.

Thanks.

I cannot say with 100% certainty, but I strongly suspect the radius is there to reduce stress and to decrease the likelihood of cracking during heat treatment.
