Re: Copying a control knob by moulding
That sounds very good, but for brass inserts, this is where you need a little lathe. You don't even need a screwcutting facility for this job so one of the little 'toy' jobs would be fine.
Things like a bakelite knob with the inner collar cracked, you can just turn out the broken collar section, machine up a big brass piece to fill the space, araldite it in, then drill and tap the grub screw hole straight down the original hole.
