right, I'm afraid I need to return our enjoyable discussion on bench design to the far less entertaining real world and report a minor catastrophe on my bench build. Remembering I had some cut brads left over from when I did the floorboards in the spare room I nipped out earlier this evening to do the glue up on the legs.
No doubt exacerbated by the daft choice of nails, existing cracks in the top of two of the legs widened significantly - the one at the back in the pic (on the left) is the least bad: the crack pushed the inside corner towards the rail so that the shoulder of the half lap no longer connects with the face of the leg, and that the leg is pushed out of square. Sadly I did not notice until I had driven the first nail completely home, at which point I decided I had little choice but to continue.
The one at the front looked okay until I banged in the last nail when the crack suddenly opened up. At first sight this one looked correctable in as far as the outside edge was pushed away from the rail and could be chiseled/planed back to where it should be, but the split is very wide and presumably the joint is no longer any good as the nails have nothing solid to hold on to in the rail part. Also, this bit of leg has to receive nails from the apron and bearer which I fear might cause it to shatter all together.
I have a horrible feeling these are 'start again' errors, but any advice gratefully received.
I am so despondent that I can't even muster the energy to reply to Jacob's latest grumbles
