[RE-wrenches] Truss finder

[Christopher Warfel]

There are very good roof mounting systems that do not require finding 
the rafter. There was a thread on this within the past two weeks.  I 
understand the comfort of lagging into a rafter, but unless you can see 
the rafters from below, you'll never know 100% you did not come out the 
side of the rafter, especially if the rafter is checked. We use the 
hammer, two pilot holes to establish the rafter edge if we are attaching 
to the rafter. That is a cool tool though that I never saw before.  Chris
