I am building an iroko gun that will shoot a 7mil shaft and I will varnish it. The gun will be laminated with West System 105 epoxy (+ 205 fast hardener) and I will varnish it with epoxy.
I just can not figure it out what bit to use for the open track : will 8mil diameter round bit be ok?

I think that the epoxy varnish will add also a layer inside the track but don't k now how thick.
About varnish, I intend to use the same West System 105 epoxy but I do not know if I can use the same hardener as for bonding, the "205 fast hardener". I've seen that West System is recommending a special hardener for coating - 207 Special Coating Hardener, but maybe there is a trick for useing the same 205 fast hardener as for bonding.
