So with the recentish acquisition of the HM-46 late last year, Im spending a lot of time making tooling for the mill. A few simple things done, an arbor here and there, it was time to tackle something a little more abitious. I had a few new skills to pick up in this, Ive not cut or measured dovetails before and it was the first chance Ive had to use my rotary table to index the dial.

Its taken me quite a few months but its finally done. Its had a couple of test bores and it works a treat. Interestingly, I was prepared to make a tap to create a very fine thread for the radius adjustment screw but as luck would have it, the right animal actually turned up on ebay. 7ish bucks for a M8 x 0.5mm tap and I was laughing. Cutting the matching screw was a delicate act though, not a lot of thread depth between needing a spanner to turn it and loosy goosy. The first one turned up a treat, only for me to cock it up five minutes later when I was doing the two larger rings on the end. Oh well :(
Also in the stuff-ups department, dont mind the groves in both ends of the moving block...thats...uh...so I can turn it around and use it in reverse if need be? Its definitely NOT because I machined the wrong end by accident.
