I use the thickness planer by running the iBamboo on a sled.
The sled is the about 1" thick blue foam used on the side of buildings cut about 8 inches wide. It snaps in two at this width I think. I wax up the underside with furniture polish.
Leave the bamboo long because there will be some Skype ??
On each end. Remove 10 to 15 thousands at a,pass.
The use of some sort off coarse collection helps with clean up.
I usually remove material till the edges are,1/16 .
Then cut out the bow shape and run through again till edges are thin again.
Finish ends on belt sander after cutting off excess length.
