@awesomeframers: Now that the HVAC crew is here, we are dilling and mounting blocks. Normally they would do their work and we'd side around the penetrations, but we don't aways get what we want. This was LP smooth prefinished siding. 6" @Diablo Tools hole saw and then we'll mount a block and drill the block. @Makita Tools USA XGT right angle drill makes it easy and doesn't break wrists. Bummer there is a seam there but life happens. Can't move the vent location due to proximity to windows. #makitatools #diablofreudambassador #framersareadyingbreed
