THere was an article in FWW (Fine Woodworking) in the early days about building your own drum sander. I believe they have an archive you can search on there website. finewoodworking.com
Lynx,
This book has plans http://tinyurl.com/bl7xb However, it requires you to push stock through rather than being power driven - reckon it's very tiring!
hi lynx,
have a look at the u-beaut woodworking forum from aussie, there has been one or two made here and a bit of info may be gained.
i took the easy way out and bought one!
seeyasoon mik.
forgive my ignorance... but sureley by the time you have spent the time and money building one of these you could have bought a proper one for not much more?
