| Jul 24, 2017 at 20:28 | comment | added | Graphus | The screwed-on cleat/batten can't be left in place as it constrains cross-grain movement, the classic movement issue with tabletops (that so many modern designs fail to account for... including so much stuff built with an over-reliance on pocket screws). | |

| Jul 24, 2017 at 19:59 | comment | added | aaron | @Graphus is the OP talking about an edge joint? if so, there's no relative movement of individual boards, so why would the screws confine movement? also, i don't really see how pocket holes need clamps - not if you're dealing with (1) an edge joint and (2) conventional self-tapping, washer-head screws, and (3) properly counterbored pocket holes. The screws cinch things right up! | |
| Jul 24, 2017 at 18:40 | comment | added | Graphus | @DavidK Pocket-screw jig or not you need clamps, so to say they're well worth investing some money or time into is a bit of an understatement ;-) A version of the simplest type above are very quick to build, literally about 10-15 minutes for a pair (less if you don't care about aesthetics). So they're an excellent use of your time, and if made from 2x material they're super cheap. My first pair were made from pallet wood so they were actually free, not including the nails I used as pivots (didn't have any strong dowel at the time). So call it 2c for two 28" clamps, which ain't bad. | |
| Jul 24, 2017 at 18:40 | comment | added | Graphus | Suggest an edit to your no. 2 Aaron, the screws will constrain movement so need to be withdrawn after the glue sets. (Personally, I'd have two reservations about this method for a panel assembly. I wouldn't trust that this could equal clamping force without using the same number of cleats/battens that would otherwise be clamps. Second I'd hate that after this there were screw holes in the underside of my tabletop.) | |
| Jul 24, 2017 at 17:36 | comment | added | David K | The design I'm working from actually uses pocket holes, but I opted to use a tongue and groove joint instead of square boards. Can I still use the pocket holes with the tongue and groove? | |
