Apologies to anyone who also frequents Knots, but I’ve had several conversations recently about Pocket Hole Joinery. I don’t like the commercial jigs because the joint always slips (no? – must be just me then) so I use this system. Not only do I not spend loadamoney on a jig, this method produces a better result. It’s not quite as quick, I’ll grant you, but it is hardly labour-intensive!
The great thing is that creep and slippage are greatly reduced (because the screw goes in pretty much square to the face of the board). Not totally eliminated, perhaps, but much, much less of a problem.
OK, first up are the jigs I use for sheet materials when making wardrobes and the like:
The main board has an aperture of about 31mm x 100mm, for use with a 30mm bush and a 3/8” bit. It’s clamped to the workpiece with a trigger clamp and I rout a slot to 5mm beyond the centre of the board:
If I’m doing framing I use my mortising jig from Workshop Essentials Volume 2:
When the slot has been routed I use the second jig shown in the first picture. The tongue locates in the new slot and allows me to drill a clearance hole in exactly the right place:
Of course, the screwdriver needs to be bent a bit, but these are proper Robinson-pattern screws and I use a short bit and several extensions. The play in the extensions means that the resulting shaft is wobbly enough to drive the screw in whilst having the drill clear of the work:
The result is this:
I’m afraid I can’t understand why anyone would want to spend a couple of hundred dollars to do this job less well!
