Looks like my lockdown project is going to be a Mandolin from scratch. I found a old dinghy centreboard in the garage roof which turns out to be 22mm thick sapele, probably 40 years old, which will provide the neck and a sort of centreblock. There's just one problem, I'm 40ish miles from my workshop and have few tools. I've spent a large percentage of the last week converting this centreboard which has few really flat surfaces, into suitable planks mainly by hand sanding. So so far about a week to do what would have taken me a morning if I had access to my father's thicknesser...
