I have a 3-53 detroit diesel which I want to power my PTO operated chipper/shredder. The driveline to the chipper is already to go as I got an old yoke from a Chrysler driveline and welded it concentric to a 1 3/8 6 tooth spline adapter thru a concentric spud I made up which fit the IDs of the couplings. I need about 540 or 600RPM to run the chipper like it was on the back of a tractor, so I need about a 3 to 1 gear reduction from 1800 RPM which I plan to run the motor at. I have an old transmission from a 1972 dodge dart which has only 3k miles on a rebuild. first gear is about 3 to 1 so it should be ok and give me a neutral allowing me to stop the shredder when I want. Diesel engine has a ring gear on it which was used to power a backup generator for the water co. here. The ring gear has a 12in bolt circle and
8 bolts. The tranny has a 4 bolt bolt circle about 10 in dia. What is the best way to hook up these two units? I have an 11 in. Logan lathe, a Gorton 8 1/2d mill and a 10 in rotary table and figure to make an adapter from some steel plates and use the rotary table to drill for the different bolt circles. I figure I have to make two plates, one for each B.C. and then get them concentric somehow and weld a tube or something between them so I can tighten the bolts in from each side. Assuming the plate is concentric with the axis of the mill spindle, I planned to cut the plate circle out using an end mill and rotating the table clear around.then advancing the z axis of the mill until I cut through. I want the minimum amount of unbalance since I don't want any vibration which would probably mess up the bearings in the machinery. Not sure how thick the plates should be. Is there a better way to do this? Am I missing anything?- posted
