One of the most useful tools for making intarsia is a Dremel/Proxxon or similar rotary tool and most people will have a 1/2" sanding drum bit? well I use them all the time and last year I bought one of these https://www.ebay.co.uk/itm/Dremel-SC407 ... SwWMhaT6v0
The idea is it saves time changing the abrasive drums without having to use a screwdriver.......well anyone who has one of these will probably find after a month or so the abrasive drums won't stay on the blue rubber drum because the rubber wear smooth so no grip
I have loads of rotary tool bits including a set of Dura-Grit bits which are expensive but last years, today after trying to sand some work i got fed up with the Dremel rubbish and noticed that I had a 1/2" Dura-Grit drum bit and tried to slide an abrasive drum onto the dura'grit bit and it fits perfect and not only support the band right to the edge so you can use the full width of the band but because the Dura-Grit has a rough surface it won't slip!
it doesn't damage the Dura-Grit and is easy to change bands then remove the band and use the Dura-Grit (it is a bit smoother than the abrasive bands and leaves a nice smooth finish to your wood).
So don't waste your money on the Dremel rubbish and save up for a Dura-Grit like this http://www.ebay.co.uk/itm/DURA-GRIT-HOL ... SwOyJX37AF
then buy your 1/2" sanding drums NOT from Dremel but from Nail manicure shops on Ebay just as good as Dremel but VERY cheap.
