Benz Refs stripped screw hole


Is there anything that can done for a cartridge with a stripped screw hole?

IIRC, the Benz is a wood body.......

(1)   Make a paste w/ some sawdust + wood glue
(2)   fill in the stripped hole
(3)   when it dries, drill a hole with drill bit that is SLIGHTLY SMALLER DIAMETER THAN SCREW!!

The hole will kindof self-tap when you insert screw for first time.   Should be nice and tight now.

Benz has a wooden shell but the chassis is threaded aluminium.
Threads are 2.5 mm so perhaps if you try 2.6mm screws might help ?
Had the same thing with a Dynavector Karat 23R (non-standard size) that I bought used. 
I used slightly larger nylon screws - they're soft enough that they won't do more damage
