The last days have been spent "carefully" glueing up things. 40 individual pieces of timber into the 12 main leg section components.....
This has gone reasonably well, not perfect, but no horrendous failures. One of the long horizontal sections (the middle batch) has a slightly short middle piece, but I figure I'll fix this when glueing up, as I want to work from getting the outer dimensions correct and I'll simply patch up whatever gap remains.
Putting these to one side I started on the three box-like sections that make up the centre of the base, these are all being done individually and then will be glued together. Here's the first one in the veritas frame clamp, which I found really simple to use and adjust.
This was repeatedly checked for being the correct length, width, and then across the diagonals which I'm glad to say I managed to get spot on after a few minor tweaks. One downside that I didn't spot was that whilst I thought it was sitting perfectly flat on the surface it turns out that after drying it has twisted ever so slightly. I am hoping that this can be corrected once I start the next stage of glueing.
At least the dimension across the glued up parts was spot on to the mm - 388 needed, 388 achieved.
The outer boxes were slightly more complex, as each has one side that's made up of 5 components. Fortunately this was pretty easy to clamp up, and turned out OK. Phew. The red clamps are to stop it arching.
Once dried, I checked its overall length against the plain side, and job done.
I'm now glueing up that box section. The third one won't be done until I've done a dry run with the two finished sections and the parts of the third, as I need to make sure the overall length is spot on, so I can slightly narrow (or widen) that last section by a mm or two if needed.
So next up was a dry fit of the two main leg sections. I'm pleased, certainly not disappointed, although there are gaps. The good news is that the most of the gaps and places where two glued together boards aren't joined absolutely in line will be hidden by either being underneath the bench or covered by the shelf at the bottom.
More importantly, the dimensions of the first set, i.e. height because that's the important one, is spot on to the mm. The other one was 1mm out on one side, but then I realised that was because that's the piece that had an error and I'd not left a compensating gap. I nudged it up with a hammer and job done. I just have to remember that when I add glue!
This was by far the worst effort.....
I don't think it'll look quite as bad once I've tidied it up after glueing, and anyway it'll be attached to the underside of the base so not even visible.
On a final note I have to say that I really like the look of plywood as it feels more functional and "workshoplike" than a solid wood bench. I haven't decided what finish to use on it yet.
This has taken me a lot longer than I thought, but looking back if I'd gone any quicker I'd probably have just incorporated more mistakes.
next job is glueing up the two leg sections, once those are done I'll join them together. That will be my first use of pocket holes and I need to do a bit of practice first as my initial attempts were terrible.
