|Thread: Adjustable Dials for Feedscrews|
Yes, in hindsite aluminium would have been the better choice but I was using what was in the scrap bin at the time. Also thought I might put in another pair of slots for more spring loaded pads but I had enought trouble getting it assembled with two. Also in hindsite I really didn't put much effort into perfecting it in the first place.
Thanks for the tip on marking.
PS: reading thread on stirlings, you Kiwi?
I can teel you what NOT to do with your dials!
I resurrected an old lathe (a whole other story) and put metric dials on all the feeds - there were none originally. The apron feed dial ended up about 90mm dia and 20mm thick. I turned this up from mild steel, put a couple of slots in the back to hold a couple of springs and nylon pads to 'friction lock' the dial to the shaft. Looked good when it was nickle plated.
In practice the dial is so heavy that when I am traversing the apron the inertia caused it to move out of position every time I start and stop.
Next job will be to try and squeeze in a thumb screw to lock it on the shaft, and remove some of the 'meat' from the back side to lighten it up.
