Hi All,

Hope someone is able to provide me with some advice for my woodworking hobby. I have some hard and soft wood off cuts form a local tree surgeon which are mainly the full circumference of the truck horizontally, but hollow in the centre and I want to smooth the inside of the trunk but am unsure of the tools to use as manual sanding is not working and the extent of ridges and curved shape makes basic sanders unsuitable?

Any advice would be greatly appreciated.

Kind Regards

How about a spindle sander? You could either use a reciprocating model or one that attachs to a drill press.

I use Sabuur Tooth wood grindres for a right angle grinders. Removes it very quickly.

What do you plan to do with them? All you will have is a ring with a bark outside.

Sorry all, probably should have uploaded an image of it to help you guys…thanks for the suggestions so far. As you can see by the shape, it is a tricky one to sand inside

Put some kind of roof or top on it and it would make a great bird house :o)

what about a flap sander or some sort of round wire brush chucked up in a drill?
