changing the pin

[RSCA HOOLIGAN]

Hello ,

for changing the pin on your butt do you need to have a radial tap to do this ?
Or is the radial tap just to make the insertion in the shaft ?

Thanks ,

Christoph

Have you ever changed a pin before??

There is no advantage to a radial pin over any other pin..............

Well, joint pins don't HAVE to have threads down the forearm.
You can bore it to fit the bottom threads' OD.
You will have to grind flats and glue rings on the parts going down the forearm.
But, if your epoxy gives, that pin will come out.
And un-threaded joint screws are more prone to buzzing .

for changing the pin on your butt do you need to have a radial tap to do this ? Yes (to do it the right way).

Or is the radial tap just to make the insertion in the shaft ? No (in fact there is a seperate radial pin tap for the butt and one for the shaft).

There are two taps .
One is slightly undersized for the shafts.
You don't need two taps . The undersized one is fine for pin install.
The OD of the bottom threads of the joint screw less than 3/8.

The regular tap is useful for the A-joint if you use the regular radial connecting screw. It's all threads and not undersized.

Just make it .003 oversize and slather up some epoxy on the threads and indicate the nose.

Chucking up the pin in a lathe first and filing a slight taper to backside of the threads that are going into the butt and you don't fight anything. Let it find it's way.
