Several people have asked me if the two section screw found in the Russian can replace the single screw design of the Kayfun in order to make the Kayfun’s pin adjustable without messing up the internal build.
The answer is… well… I haven’t been able to do it.
The problem I’ve run into is that each device has a different insulator at the 510 connection.
You can’t just switch the screw assemblies, you have to switch the insulators as well or the post on the Kayfun will stick out too far (see photos below). The Kayfun’s is easy to remove, however the Russian’s is in there and GOOD. I tried to use a drill bit to push it through, no luck. Tried banging on the drill bit, no luck. With the drill bit in place, I tried banging on the 510 connection with a Jewelers nylon mallet. It moved, but I couldn’t get it all the way out.
Fearing damage to the 510 connection, the insulator (which you can already see is a little chewed up in the photos below from me trying to get it out), and the Russian itself, I gave up.
If anyone has been able to do this, let me know.
Thanks!
