strikes me as a bad idea. Besides, with round belts the belt will slip in the pulley before the pulley slips on the spindle. My 2?, Elliot On 5/3/23 4:10 PM, rcjge wrote: Hi Folks. --

开云体育Just fantastic work. ?Beautiful to just look at. ?I had to make a similar dovetail for a tool holder I needed for my Maximat but I used a shaper that I own. ?Don’t see those around shops much any more.

Re: Projects Built on the Unimat?
Tom, the outside surfaces were surface ground square prior to cutting the dovetails to facilitate accuracy of the finished tool. The dovetail cutter itself was turned in the Unimat and finish ground using my Quorn cutter grinder.Dick -- http://www.homemadetools.net/ ?SMALL TURRET TOOL POST PLANS? ?LARGE TURRET TOOL POST PLANS ?MINI- ?SMALL QC TOOL POST PLANS? ?QUICK CHANGE LATHE TURRET ?MINI LATHE COMPOUND PIVOT MODIFICATION |

Re: Unimat DB/SL cross slide disassembly…
Find a 5/16" or 8mm bottle brush. Nylon bristles will be easier on the alloy parts. If you're in the US, you can find this set at Harbor Freight,??and the 5/16" brush is about perfect. A bit of rubbing alcohol or a shot of WD-40 or similar will get any gunk out of the threads.? If you have one of the iron-framed tools, a .32 caliber gun cleaning brush would work well, but I'd not use it on the alloy parts.? 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.

开云体育My? Sherline lathe works with metric collets as long as I use the metric sized collet sleeve, but the Sherline collets will not thread onto my Boley drawbar.? The threads are a bit larger in diameter than the metric ones. Charles Daldry On 5/2/23 12:55, Ruben wrote:

Yes to your last question, anyway. :) 1mm pitch is 25.4tpi. I'd have to dig out a copy of Machinery's Handbook or other reference to calculate it.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.)

Wouldn't a .275-40 thread be more like a metric M7-0.6 thread?? It's my understanding that while Imperial threads are listed listed as threads per inch, metric threads give the diameter and the pitch distance between threads.? An M7-1.0 thread's Imperial equivalent would have 25.4 threads per inch wouldn't it?
