Re: Adapting the Unimat 3 Threading Attachment
|
I recently bought one of his ELS units, fully assembled and tested, $150+ shipping from Canada. Not planning on putting it on my Unimats, though. Going to put it on the Smithy CB-1220XL my brother insisted I need. I think it's a hint he wants me to make stuff for him. ;) Bill in OKC William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

There's another group on :?E-Leadscrew That should be cheaper and better. "ELS" - Electronic Lead Screw ¡ª is an alternative to full CNC for simple bench lathes ¡ª especially those lathes which do not have a "Quick Change Gear Box". For such lathes, it would be useful to have a cheap method of sychronizing spindle speed to lead screw speed. If this can be realized electronically, then all threading can be done without the necessity of changing manual gears. Also, all saddle traverse speed ratios become possible. The aim of this group is to develop a simple, cost-effective electronic and mechanical system for implementing ELS - which in theory would be cheaper than CNC, and which can be ported to hobby-class bench lathes. Member John Dammeyer has led the way in these discussions. He has designed a system, which is described in a comprehensive article "Electronics Gear Control" in the magazine "Circuit Celler" ¡ª Nov/2006, Issue 196, pp 36-43.
