Tunnel ram or no tunnel ram...
Did some drilling and tapping. PV channels had to be tapped to 8-32.
Also did some measuring and it turned out 2 bottom emulsion holes on each side are 0.033” and verified the top one at 0.029”.
I’m trying to understand this setup. What’s the role of bottom emulsion holes? Do they deliver extra air at wot?
