Does anyone have a clever way of mounting barrels into the termite resin single 88 mounts? Last year for my Derfs I tried drilling a hole for a barrel, but the flexibility of the termite resin + being a small part caused all sorts of woes for me. Ultimately they all ended up with barrels, but I cringe every time I look at them (barrels aren't all centered up, some are at slightly odd angles, etc).
Maybe try using a drill press and a drill bit one size smaller than the barrels. Other than that not sure. I did mine that way and they turned out ok.
