I have swapped a toyota 3TC engine and 5 speed into my midget. I have to mate the toyota drive shaft to the midget drive shaft. I will have a drive line shop weld everything up and balance the drive shaft. The ID of the toyota drive shaft is 2 7/16" and the OD of the midget drive shaft is 1 3/4." The toyota drive shaft is as long as it can be and the midget drive shaft will get shortened by probably 15" to 18"
I am making a bushing that slips inside the toyota drive shaft and over the midget drive shaft. Here's my problem. I am making the bushing out of some round bar that I had on hand where one end is 1 3/4 OD and other end was 2 1/2 OD. It is held in the lathe with the 1 3/4 end.
If it weren't for this difference in OD's I would bore the bushing to 1 3/4 without taking it out of the chuck. I can't do that in this case.
I believe that I have two options. One is to put the bushing in a 4 jaw chuck dialed in to the OD. Then bore the 1 3/4 hole.
Or start the 1 3/4 hole in my current setup. When I get to around 1 1/2 switch the bushing over to the 4 jaw and dial it in using the center hole.
This is probably one of those 6 of one and half dozen of the other type decisions. I have been going back and forth probably overthinking this. Which would be better or does it even matter since either way I will be dialing in bushing?
