I have complete most of the chisels and I am very happy with their performance. But definately see some areas where I can improve.

The currently the set contains:
Straight 1/2” rod with round carbide cutter
Straight 1/2”rod with square carbide cutter
Curved 1/2” rod with round carbide cutter
Straight 5/8” rod with HHS insert
Curved 5/8” rod with HHS insert

From Hollowing Chisels

Straight 1/2” rod with round carbide cutter:

This worked well and left a good finish but I prefer to use a gouge for final surface, I will mount this cutter on a 3/8” rod to see how it performs with the extra clearance.

Straight 1/2”rod with square carbide cutter:

This work excellent for roughing but in hind sight should have gotten the radius cutter.

Straight 5/8”and Curved 5/8” rod with HHS insert:

These worked like a champ for removing material but did not leave the surface smooth. Albeit the piecewas punky wood. I also need to get square inserts, I ordered round inserts which I had to grind the top flat and put a fingernail grind on. The grinding of the top I believe increasing the chatter of the tool.

I also got some 1 3/8” aluminum rod, cut it to 18” length, drilled 3/8” and 1/2” holes on the end of one and 5/8” hole on the other.

I also still have a number of rods for future tools, I am sure that I will be using them. I already know I want a chisel with a more extreme bend to get under the lip of a hollow form.

Hey Ben! Those look great.

How are the small tips ground? I can’t really tell from the pictures.

What kind of chucking do you have on the lathe? If you have something that holds well, you can also turn your AL handles and give them a bit of shape as well. Lots of fun but a bit slower than turning wood. How big a spindle you have on the lathe? (Through the spindle especially)

I have a straight tool with a 1/4” square HSS bit. I love it. Maybe I’ve was lucky but mine did leave a nice finish. I was fairly hardwood and I was taking light cuts. Sometimes I think this is all magic and we are subject to the whims of the wood elves/nymphs….
