I'm not having good luck today putting up sheetrock. Been years since I put any up and I'm trying to finish my new shop today. Couldn't find my old drill type dimpler that I used to have, go I bought a new one. Only doing a 24'x28' room so I figure $9 would be better than $90. I absolutely could not get it adjusted to work reliably. So...went to HD and picked up the Ridgid screwgun for $80. And the same thing happens. One screw will go in perfect, the next one ratchets out just proud of the surface. Can't seem to get any in right along the bevel edge, might as well use my drill. I'm having a heck of a time here!! Whats the secret? I try to drive the screws in straight with my body right behind the gun. That works the best, but my gosh, you've got move for every single screw. What do I need to try?? Thanks.
