They sound like the main drive and standard duplex gear for the old woodchuck model (MA-12). Yes Legacy made a change to the gear count during the middle of the model 900's. I don't know why, I could only guess that reduced tooth count on the newer machines (larger teeth) decreased manufacturing time. 88 versus 180 teeth and the larger teeth are easier to maintain definition and increase laser speed.

Does this happen on the small teeth version? -Tim ----- Original Message ----- From: 'joe biunno' via Legacy Ornamental Mills To: legacy-ornamental-mills@googlegroups.com Sent: Friday, May 16, 2014 1:38 PM Subject: gear question can anyone explain...i have two gears that seem a bit out of place...one is 7 1/2" dia., fine tooth, rectangular hole(headstock gear) but with no holes for indexing...the other gear is also 7 1/2" dia. and has the smaller 2" gear with four bolts bolting them together but the smaller gear is a fine tooth...could this set be from a woodchuck machine, which i do have?...for the record the paperwork i have says the machine was made in 1995 and is a model MA-12...obviously it seems legacy changed at some point to that larger tooth, headstock gear meshing with the smaller, 2", large tooth gear...was/is there a specific reason for the change?...is the fine tooth better than the large tooth?...any opinions out there?thanks...joe -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
