What Did You Buy Today?

The rear shaft goes in an AXA holder.

Let us know how that works out.

Today I picked up a small Jacobs chuck...



It will hold from 3/8" to 1" shanks. It's in pretty good shape, just dirty. The jaws show minor use, but are still decent. It opens and closes very smoothly and has a MT4 arbor... that is perfect for my Buffalo Forge camelback drill press.

Not too bad for $28 I think...

Geez... I guess I was so excited about the chuck that I forgot about the other half of my daily haul...



3/16" letter and number stamps.

I will need to stop buying tools very soon because I am *definitely out of room*, & my financial landscape changes (degrades) after Thanksgiving.

Used 1” hole, 3” square Criterion boring head with 1-1/2”-18 threads.

I asked very nicely, & the eBay Seller knocked $15.00 off of the asking price.






This set me back $175.88, including tax and shipping.

What a clean looking boring head!

I just got this Shars No 00 Keyway Cutting Broach Set.

I'm using it to cut a keyway in a 3/8" bore with a 3/32" key. I believe the shim is only used for the 1/8" key, is that correct?

I purchased a similar but noname set. It came with two shims. For the pulleys I broached I found 1 shim wasn't quite enough. Two shims were slightly too much. So you will have to experiment. It will be obvious if you need shimming after the first broach. Fortunately shims are easy to make.

I'm thinking for the quick and dirty you could set the broach with a shim behind it in the bushing at the full-stroked position and measure the height from the back of the bushing to the edge of the broach. Take a caliper set to that dimension and set a jaw on the ID of your pulley/work and scratch the other side to mark the depth of the keyway.

Or, as WobblyHand mentioned above, just go for it and see if you need to add a little more shim. First pass without the shim, and do a second pass with the shim if the first pass isn't deep enough.

Nice. Looks like a super handy little broach set. I’ve always had broaches on the wish list but the cost vs utilization just never made me pull the trigger. I’m going to check that one out tho seeing as Shars is only a few miles from me.
Thanks for posting that.

I think I was correct in the 3/32" broach not needing the shim. See this page from the Shars catalog.
