I just bought a 1975 vintage Anayak FV2 mill, imported to the US by DoAll. It has so much grease, muck, and yuck on it, I need to clean it. So far I've tried citrus based solvent, paint thinner, automotive, parts cleaner...... Applying it via green and brown scotch brite pads. Any suggestions on a degrease process?

Called Series II Interact 2. Ah. The "Super Beetle" of the Bridgeport line. Better in so many ways that the previous model, then for some reason they quit making it and went back to the original design, though somewhat adjusted/tweaked. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------ Message: 3 Date: Fri, 27 Mar 2015 21:10:23 -0600 From: Gregg Eshelman <g_ala...@yahoo.com> Subject: Re: [Emc-users] Possible New Lathe To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Message-ID: <55161b9f.1080...@yahoo.com> Content-Type: text/plain; charset=utf-8; format=flowed On 3/27/2015 9:08 AM, Bruce Layne wrote: > In communist Russia, lathe turns YOU on! > > I'm looking forward to seeing your newly converted CNC lathe.

I'll have the gearbox off my $50 9x20 but need another. 9 speeds on one box feeding a second box with 9 speeds... I wonder if any combinations would be duplicates? I milled out the channel in the saddle last night but not as drastic as Denford did on the ORAC Compact 8 clone. I'll be using white acetal to make the nuts and replace the wee little cross slide screw with a 3/8x10 ACME and the leadscrew with a 1/2x10 ACME. Cross slide motor out the back and addons made to not restrict the slide travel, not like how Denford cut off the rear of the slide at the nut because the ORAC had a plate attached to the rear of the saddle. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------ Message: 5 Date: Fri, 27 Mar 2015 21:30:50 -0600 From: Gregg Eshelman <g_ala...@yahoo.com> Subject: Re: [Emc-users] Possible New Lathe To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Message-ID: <5516206a.2070...@yahoo.com> Content-Type: text/plain; charset=utf-8; format=flowed On 3/27/2015 10:44 AM, Gene Heskett wrote: > > > On Friday 27 March 2015 11:08:18 Bruce Layne wrote: >> I'm looking forward to seeing your newly converted CNC lathe.

Without it, the velocity computed by subtracting last position from current position has huge jumps when each count comes in.
