When making studs and sleeves for the Cross-Twin engine I was having trouble with consistency in length using the collet chuck. I was using a spindle stop but it seems that the clamping of the collet in the chuck was moving the parts. I have looked at buying a stop for the collets for some time but decided yesterday to have a go at making my own. I used my new favorite steel for the body of the stop and drill rod for the movable stop. Stressproof steel is so nice to work with.
The thread on the inside of the 5C is an unusual size -- 1.041-24.
There are some of the stops that are threaded but I wanted a sliding stop that would be held with a set screw.
Sketched up the parts -
Started from a 1-1/2" bar.
This steel cuts so nice!
Cut the 1.041" for the threads with the relief groove.
Cutting the 24 tpi threads. Test fit the thread with a number of the collets as some are tighter than others.
Body has been threaded, drilled and reamed for a 3/8" sliding stop. Tapping the #10-32 set screw so that the sliding stop can be used to finish the lathe work and hold the body to mill the flats for the wrench.
Finishing on the lathe.
Using a collet block on the sliding stop to hold for milling the flats.
Not tested yet but high hopes that it will work better than the long spindle stop.
