 |
|
I have to drill out a couple cherry max rivets. In the past I have first driven out the central shaft and then it is easily drilled out. Â But these 2 are being difficult. Â I figure I'm not doing the right way.
What's the best thing to use to drive out the shaft?
Should I try to drill it out a bit first with a small diameter drill and then hit the shaft?
Any suggestions would be appreciated.

Tom,
The bugger with these things is that the center shaft is of a harder material than the remainder of the rivet. Depending on where the shaft broke when it was being pulled, you may not need to drive it out. In one case, I used a broken drill bit (with the broken end squared off) as a punch to drive out the mandrel (shaft). In another case, the mandrel broke off deeper inside and I was able to use progressively larger bits to drill out the head - start small so you're taking off minimal material with each successive drilling and the rivet has less of a tendency to spin.
YMMV,
Ralph

a properly set cherry has a locking ring that is holding the the stem, cherries can be a pain to drill, for a button head i have always found it easier to sand the tops flat with a die grinder before i have to drill them. else make sure that you center punch them well before you start drilling. and use a short 3/32 punch the standard lenght punch is not strong enough and they bend/break. cut one down to about 3/8 of an inch.

This is the way I do it:
Drill into the locking ring. Dislodge it with a drift or similar tool. Knock the pin out. Drill out the head of the rivet like you would do with a solid rivet. Pop off the head and punch the remaining rivet through with a drift.

Peter:
Not sure what you mean there. Which end is the "locking ring" on? Do I drill on the factory head end or the shop head end?

Check this website.

This should clear it up.

Hi Tom,
I've found that you can use a sanding disk in a die grinder to sand the locking end (shop head) down a to the point that you can drive the pin out with a spring loaded center punch. Just sand off enough of the shop head to release some of the stem's friction. I use an old punch that no longer has it's point attached. I stick a used cherry max stem in the punch where the point used to be & drive the stem out of the rivet. It takes about 10 or 20 snaps with the punch, but it's easier on the surrounding structures. Then as you know, it's easy to drill out the rest. Good luck.
