Well, thank feck.
I lined the drawer with green baize felt, which was as complex as “apply glue, shove cloth in place, run knife around inside to trim”. Then I drilled pilot holes and screwed on the drawer pull. Took the drawer inside, put it in the frame, evaluated how bad the rocking was, and trimmed the two high legs and re-chamfered the new cut surfaces. No more rocking. Then I assembled the whole thing, put on the mattress and a fitted sheet, and that’s it, it’s done.
It didn’t turn out too badly I think, given that it started life like this:
Have to say thank you to Herself Indoors here for looking after Junior for too many weekends while this got done. There’s a small army of stuff around the house that got ignored while trying to get this finished, I think that’s going to be my shed work for the next few weeks (not to mention that the garden is in dire need of fixing and the shed itself is now buried in shavings and rubbish and needs cleaning and the car boot needs fixing and we really need to change the car while I’m at it and …. well, you get the idea).
All that’s left to do now is figure out how the hell to get this thing to my sister’s house…
EVEN MORE last minute fettling (levelling the legs, screwing on the drawer pull, lining the drawer) Close door of shed, lock it, walk away and never do another project with a deadline ever again.
