[RE-wrenches] Pilot Hole Template

Thu Dec 13 08:45:36 PST 2012

I like the easy feet for those difficult situations. Does the AHJ require a flashed connection to the roof?  The easy feet might not be allowed if they do.

Come pre-made with EPDM.  Just snap a line, set and screw.  Obviously you will need to do some math to make sure your decking material is substantial as well as anchored well to the blue board.  I have not used them yet, but will be putting up 20kW next month and will report back.  That being said, anybody else have experience to report with them?

>> We just finished a similar roof mount project but had the good fortune to be going into 6x14 beams at “ 48” o.c. “. I put the on center dimension in quotes loosely, and spent a couple hours prior to drilling the first hole checking layout of the beams, directly under where we’d be drilling. The ceiling rafters varied in layout an inch to 8” so this paid off!!!
>> We used a 12” x 3/16” pilot bit, for our 8” Simpson SDS galv lags. I eyeballed the angle into the beam, approx 10°, as we had 4 bolts in each 1.5” pipe flange base to land into the beams. The trick is having the 8” lag bolt follow the hole into the 2x6 pine decking and beam. This wasn’t as hard to do as we first thought it would be, and didn’t miss a one.
>> Hitting a 3x10 is going to be trickier, and your jig should help immensely.

I took a quick mount, inserted a 1/2" EMT coupling (after some filing) and stuck a 8" piece of 1/2" EMT in the coupling Nd tightened it down. Checked it with my square to ensure it is coming out of the flashing square to the world.  I haven't drilled a hole yet, but will update.

It took about 12 man-days to install 200 of the base plates and L-Feet on a flat roof with wood blocks on a metal deck with about 3" total from the rolled roof surface to the metal deck. We custom-cut patches to go over the metal flashing supplied with the base plate.

>> Hello,

>> The roof I'm currently working on is not a typical roof.  The construction is as follows:

>> 2"x6" tongue and groove exposed inside, with 4 inches of foam (blue board) and on top of that 3/4" plywood with asphalt shingles on top of that.
>>  
>> I'd like to make a template to ensure that my pilot bit doesn't wander when I'm going through the blue board.  If I miss the beams inside, the hole or the lag would be exposed.  
>>  
>> Anybody run across this? Ideas?  I thought of maybe using a qucikmount flashing, with a short section of EMT attached to help guide the bit....
