Review on 🔩 HHIP 3900-5129 ER-4 Collet Block by Richard Alemayehu

This is a well made and accurate tool at a very competitive price. It arrived the very day I needed to make the tension wrench and was much more convenient to use than adjusting the platter. I had to fiddle with the exact dimensions of the part due to some differences in chuck mounts (!), but the block did the checking of the fit and resetting the fixture in the vise all at once - you couldn't do that with a turntable. I also ordered a hex. I have always been happy with H&H tools.
