I have to route some 3″ ABS through a couple of 2×10 floor joists. I know that I can’t bore a hole larger than D/3 but I have no other option. Do you think the inspector will sign off if I double up the floor joists? Any bracket options out there I should know of? Thanks in advance guys……
The Makita LS1219L makes precise repetitive cuts and can handle wide and heavy timbers.
