Revo Conversion

I've had several customers send me their Revo shafts so I can convert the threads to fit a 3/8-10 modified pin.
I've also had several cuemakers ask about the details of the conversion. Following are 4 pictures to document the procedure. It really is quite simple so let's get to it.

In this photo, you can see the black linen phenolic plug resting above the collet. It is .498" diameter and has shallow threads (I used a 1/16" pitch about .008" deep) to serve as glue grooves. The plug is 1.400" long and has a 9/32" diameter hole drilled about 1.330" deep. The Revo shaft has already been bored to .500" x 1.400" deep and also has shallow threads... with the same specs... for the same purpose.

The plug is partially inserted just to show how it goes. It will be epoxied in place.

After the epoxy sets, the bore can be opened up to .309" diameter and a skim cut taken on the face.
Note the similarity of the black linen phenolic used.
The threads cut in this shaft will be as reliable as the original's.

The proper threads have been cut & chamfered and this shaft is ready to use.

Before & After

And who doesn't want a matching JP?

This can be done to any Revo shaft but it's much easier and cheaper to start with a shaft having Radial threads. Removing the brass insert from a Uni-Loc QR Revo is more difficult and, therefore, more expensive.
