Good job, Cam. Incidentally, where do you get your sandpaper in those grades?
The 80 was on a roll I found in the garage, it made short work of the paint and didn't scratch up the willow underneath too much! No idea where that came from though!
The 120, 180 and 240 I did on the orbital sander, so they're the velcro discs you buy for sanders. I got them whatever hardware storr I happened to be near when I needed them.
The 320 and 400 I did by hand. That sandpaper came in a multipack of wet 'n' dry from (I think) toolstation. I've got some 600 and 800 in there too, but that would just be silly (and fibreglass sheets don't stick when you sand it that fine!)
Why sand when you can just buy new willow?
You sand your old willow so it looks nicer when you sell it, which gives you more money towards the new willow!
