It's time to start assembling these carcases.
So far in this project, things have gone suspiciously smoothly, not the whisper of a hint of a suggestion of a cock-up. I should have known it was too good to last
I made a rod for the positions of the pocket screws. This way I only need to measure out once and thereafter I just copy the pencil marks.
The eagle eyed will notice that I am marking on the front edge. In fact this photo is staged because the original was out of focus, so I didn't really drill my pockets along the front edge...
I like and hate pocket-hole joinery in pretty much equal measure. It's strong and fast, but most of all I can take it all apart for transportation. But it certainly ain't pretty.
The little jig is well-made and easy to use. Line it up with the pencil mark
make sure it is flush with the edge
and with the stop-collar set correctly, drill away
Well, actually, there are a couple of problems.
The first is dust extraction, or rather the lack of it. I have to operate the drill with one hand and hold the DX hose with the other. At least it switches on automatically when I trigger the drill.
The second is the quality of the cut. It's not so bad when I'm drilling in line with the grain, but when drilling across the grain there is considerable tearout as the rotating drill pushes the veneer in on the RH side but rips it up off the LH side.
So it needs cleaning up a bit with chisel and sandpaper.
When you have dozens to do it seems like an annoyance.
The third problem is when actually screwing. The screw is at an angle, and that means it is pulling in the direction we do want, but also a little bit in the direction we don't want, pulling the board out of alignment. So clamping the boards up to within an inch of their lives is essential. I'm assembling on the plinth base (old towels- one I seem to remember buying on holiday in Greece in my 20s
- preventing scratching between the plinth and the carcase side) so that I can get clamps in properly.
Edit - this carcase is on its side, it's easier to assemble this way. The open front is on the far side, away from me.
And this where the cock-up revealed itself.
Remember when I lipped these boards? I cut them full-size before lipping, as I didn't know how much cleaning up I would have to do. I planned to trim to size later.
Well I forgot. So all the tops and bottoms were 2mm oversize. I have to
rip this off the back edge (otherwise I lose all my front trim) but I've already cut my pockets, so the screws end up 2mm further in than they should be.
Fortunately the screws didn't poke through the face surface, I got away with it, but it was more by luck than judgement.
So I have one assembled cabinet and not a screw (nor a gap!) in sight.
It weighs a ton, and it was all I could do to get it upright on my own, but at least I can now sort out the interior, dismantle it and get it out of the way before I do the other two; my workshop has panels everywhere.
A loooong time ago, in a previous life, I made a router jig to make pocket holes. It wasn't as fast as the Kreg, but it was very clean and although it was no prettier, the screw went in straight rather than at an angle. I'd forgotten about it until I did this and all these weaknesses reminded me of that jig. I think I should revisit it.
