However, measuring and cutting long studs is slow and not that accurate with just a tape and a chop saw.
My instinct is to mount a laser distance finder on the left side of the chop saw blade aiming the laser to the right (I am right handed) and coming up with some kind of easily clamped/removed target that can be consistently placed on the right hand end of the board. That way, as the board is slid left and right, the laser would record the effective distance from blade to board end.
However, this would require the ability to dial in an offset into the laser distance tool to correct for the distance from the blade to the actual laser tool mount mount. IOW, the tool has to be calibrated for the "real" distance from blade to board end.
1) Do distance finders allow offsets like that to be dialed in? 2) Is there a better/faster/smarter way to do this? 3) Is there already a tooling system for just this problem?
P.S. This question is actually on behalf of a friend of mine who is a professional builder. I first suggested mounting a long auxiliary fence on the right side of his chop saw (with proper support) and then sticking on a self-adhesive tape to the top of it. He said he's already doing this but it's too slow for large projects. You have to run back-and-forth from the end of the board to the blade to get it right. In some cases, he's using sticks up to 20' in length so it's a fair walk.
