You may even grow to love the endless ribbons twisted round your headstock.
I have done a few of those blanks
Yep, Pete. I just used 'acrylic' as a generic term and understand that it is polyester resin. I am an 'acrylic' novice so don't use the correct terminology.Technically it is a polyester resin so chemically different from the usual Acrylic coloured blanks sold for pens. It is a clear version of the resin usually used to make boats, motor homes and other fibre glass stuff.

Thanks for that Mark. Is car cutting compound too abrasive?Hi Alan, the secret to a good finish is patients...
I use Axminster mesh strips to sand to 600, but after each grit radially used I then axially sand the blank lightly(lathe off) then wipe the blank with a wet cloth to remove any residue. Once down to 600 I switch to liquid abrasive, I have been using Farcla which is a boat/ car paint finishing compound but of late I have found another from Machine Mart which works very well too. Again a little on blue towel rubbed in then polished with the dry part....there are 3 grades to this, which gets progressively thinner as the grit thins....Also i try to keep things cool and try to stop any heat build up.
All this is academic though as you won't turn anotherView attachment 41517

I turn them with a gouge and then switch to a skew. With the finish off the skew I can got straight to 400 grit paper or sometimes if needed 320 grit. After sanding a grit with lathe on I stop it and sand lengthwise along the blank, then wipe off the dust and grit. Lathe back on to #0000 steel wool and then off, wool lengthwise. Then I wipe the dust off before buffing with the three Beal buffing wheels. Tripoli, White Diamond and then the Carnauba wax. I buff across the blank first then diagonally both angles and finally lengthwise flipping the blank end for end so the wheel doesn't grab it from you. I clean off the blank between wheels so as to prevent coarser compounds from being carried up to the finer one next. They are nice and shiny and that's as far as I feel the need to go.
I do the same with a CA finish on wood.
