Thanks for the compliments. I've not had a chance to finish off the design as yet (far too many other things going on at the moment). However, CruzThs was going to have a look at machining some from my CAD files. I don't know how he's got on with it (if at all). IIRC the design is pretty much finished except for the hinge plate mountings and the knob detail for affixing to the shaft. I can't see me being able to make any progress with it in the near future. Someone else will probably come up with another design before I get around to it. I'll have to see how my "copious amounts of free time (tm)" goes. I don't even seem to be able to get on the BBS very often any more.
