So the glue up of the side panels didn’t go quite as planned, most because one of the panels twisted. The cawls helped a lot, but there is still a minor twist in it. I had considered building a new side panel, but I think I’m going to persevere with it for now. I see a lot of clamping my future!
I also had a minor blow with some epoxy. I don’t use a lot of epoxy, so I’ve been buying the 5 minute stuff that comes in the twin syringe so you get equal doses of resin and hardener. Except I don’t think the batch I mixed to seal and stabilize the knots on one of the panels had enough hardener in it or I didn’t mix it enough. I mixed and poured it yesterday evening in preparation for today’s day in the shop, and came down this morning to a goey mess. The hole I sealed on the other panel was fine so I know the epoxy itself was good, but I had mixed the batches separately. I’ve managed to clean off the resin from the panel and I’ll have another go at sealing the holes. I’ve sanded the side panels with some 80 grit as it’s easier to do that whilst it’s flat. This has removed the majority of the epoxy mess, but my sander is too big to fit in the flat panel so I’m going to have to have another go by hand. I’ll probably sand all the way up to 220 in preparation of finishing as it’ll be easier to do before the glue up.
With the rabbets in the side panel done (very easy on my new router table :), I’ve glued up some panels for the top and bottom of the carcass to the desired width.
I finished today laying out the dadoes for the shelves. Next week, I’ll route the dadoes and resaw the stock for the shelves and dividers. If I have time, I’ll glue up the main carcass.
So my re-working of the epoxy has improved the situation for the long dark streak but the two holes that had already been filled by epoxy, I wasn’t so lucky. They were rather deep and I didn’t take the old epoxy which it turns out was a mistake. Overnight the old epoxy half hardened and had gone white. So I spent an hour digging out the old epoxy and cleaning out the holes ready to be refilled. I’ll try again to fill the holes again tonight.
The long dark streak through the middle of the board caused by a branch coming out from the trunk which I’d stabilized with epoxy. Epoxy is gap filling meaning as you apply it, it will flow into gaps. I pasted a layer of epoxy on the dark streak which set good and hard. Ordinarily I’d use my random orbit sander to remove the excess, but the panel is too narrow to get the sander in and anyway the round disc won’t go into the corners. So I’ve resorted to using a utility knife blade to remove the excess and whilst I’m at it used it as a cabinet scraper to smooth the surface. This is very effective and can get wood smoother than 220 grit sand paper. If I had a proper cabinet scraper it would be quicker and more efficient.
