First gear...
Trident is due to deliver a hunk of 3.5" dia 1144 bar to make the gears I need from along with some other stuff on Wednesday, but this morning I dug around my junk bins and found a puck of bronze large enough to do a test gear. It took a good amount of time to turn the blank, broach the key way and otherwise prep. I cut the gear on the CNC with manual indexing, two passes to rough and finish each tooth. The 66 tooth gear I cut used one of the new dividing plates I made as well. Overall it went pretty smoothly and it appears that the gear is entirely useable. I'll mount it up on the lathe tomorrow and give it a test run. On the left is the factory 60T gear and the right is the newly cut 66T gear: http://wpnet.us/First_gear1.jpg http://wpnet.us/First_gear2.jpg |
