I think you covered it all so what else is there to say? The only thing left for me to add is on the model 200 Legacy used a .040" pitch gearing combo to cut contours with a cove bit and a template follower.
Legacy also use to sell a gear package called the "Lathe Drive Package" that had a pitch of 1/32". It looked like it cut a pretty smooth cut. It has not been around for a long time. The caveat is there is a lot of hand cranking involved. Consider this, the spindle becomes the drive and you have to rotate the spindle 32 times per inch. A twelve inch contour is 384 rotations. That's a boat load of cranks if you ask me! Personally, adding a drive to the spindle is on my list. I'm going to use a dc lathe motor. I have the Delrin bushings in all of my machine so I'm not going to do much until I get those upgraded. Then I would use my other motor to drive the carriage for a semi-automated solutions. -Tim ----- Original Message ----- From: curt george To: Legacy Google group Sent: Friday, July 20, 2012 2:29 PM Subject: How to get the best finish cut on the Legacy Hello Everyone. Its been a little quite as of late, (I know its summer and lots of people are vacationing. As a matter of fact I too will be gone next week My self. ;-). ) How to get the best finish cut on the Legacy, This one has been on my pet projects list for a long time. As everyone here knows, (at least I hope you know.) Legacy has in the past added a second motor onto the head stock of there machines in the past, On the Wood chuck this was done by the of mating up a drive gear of the motor with the indexing plate of the Legacy/Woodchuck. and on the models 2000-2200 this was done with a belt/motor linkage. And some of our members Big Bill, Russv,& M.Pung have also done there own versions. The concept is pretty simple, Move the turning faster so you can... lots of things. sand the turnings on the Legacy, have the drive screw move the carriage more slowly while the spindle is turning.(more rpms, less of a cut per rev., the better finish.) And it makes template following much easer. And the list could go on... If you don't believe me, try this trick, I use to get a much better finish on the legacy when I did not own a motor drive, I use to spin the spindle twice of every one rev, of the carriage. Or better yet, I used one of my children to spin the spindle as I moved the carriage. (I did this a few times, Now My kids wont come into the garage.) (I don't know if that's a good or bad result to this test?) ;-) The gear linkage is to fast/slow (depending if you are looking at the spindle or carriage moving.) A third way is to have the motor driving the spindle and pull/push the carriage at a slow pace You can get a very nice finish this way.Or you can do it the other ways around, drive the carriage with the motor and turn the spindle by hand... (I've not done that one yet. Just thought of it. ) ;-) So any new ideas on how to tackle this problem? I'm sure there are a 1000 way it could be done. Lets talk about your way or ideas on how to get the Legacy to make the best cut possible.
