[RE-wrenches] Pilot Hole Template

[Jesse Dahl]

The 2x6 are not the "beams" the beams are 3x10 laminated beams that hold the whole roof up, confusing I know.  The beams are what I will eventually attach to.  

I like the idea, that would allow the drill to stay "straight" when I drill my pilot hole. 

Thanks!

Taper the 2x4s so the drill would have a 'V' shape to guide thru.  Throw a block on the top to keep them from spreading out.  This should keep your holes perpendicular with the roof/beam as long as you are directly above the spot you want to hit.

These are all things that were not thought about before hand. My hope is that the 3/4" plywood will help, blue board is very hard to crush on its face, so I can only hope it holds, if not, I don't know what they will do.....
