As some of you know, I have recently had the good fortune of acquiring a gen 116610 bezel assembly:
The construction of this particular unit has been a mystery for me, until today. I have struggled for the past couple of weeks in finding a way to remove the ceramic insert from the bezel itself. Having heard horror stories that RSC themselves have problems removing the fragile insert (often breaking them), this was quite the challenge. As a result, inserts and bezels come fully assembled now.
I have not seen or read any method where this surgery was successful. I have also heard rumors of a "special" tool that RSC uses that is only somewhat successful. However, I am happy to report that I have developed a process that I can repeat, and the bezel has now been fully, and safely disassembled!
I understand that very few will ever have a need to attempt this, but for those of you interested, here's how I did it.
After carefully examining the assembly, I gathered that I would have to somehow push the insert upwards while pressing down on the bezel to release the insert. Unlike rep inserts, the gen insert is held in with friction. as such, if one does not apply even pressure, the insert will snap. If you look closely, the middle of the insert overhangs the inside of the bezel leaving about 0.3-0.4mm of clearance:
Using this diameter, I had a die fabricated out of delrin, such that it would fit inside the bezel and rest under the inside lip of the insert:
In the same vein, I reasoned that I would then have to apply downward pressure on the bezel edge only while pressing the insert up. So I fabricated a die so that the entire bezel would fit inside a recessed channel, milled to the same contour of the bezel that would only apply pressure to the outer edge:
The key was to have the bezel fit exactly and not allow any wiggle room as I did not want to risk the die slipping off during the pressing process.
Now I gently put the two dies together to test for snugness. Perfect fit:
The "crystal" press I have been using is actually my wifes grommet/eyelet press. Its beefy and very solid. I had my dies fitted with the appropriate connection hardware.
I installed the bottom die and placed the bezel assembly onto the pedestal.
Followed by the top die:
Now the moment of truth! I will not lie, I was peeing my pants. Would be a shame to destroy a brand new insert! The result? Success!
Insert is perfectly preserved. I am somewhat surprised I had to resort to this. Definitely not for the faint of heart. But with my new tools, I think I can confidently repeat this safely in the future.
Upon close examination, the insert retaining ring is metal. For some reason I had thought this was plastic.
Reassembling will be relatively simple in comparison; All three pieces will go back together and simply pressed together.
I think there is a reason I have stuck with vintage builds. Working with these modern ceramic parts can be very scary!
I hope you enjoyed the show.
