You could always make one
   Old solid steel circular saw blades were made to cut...wood!

Paper thin Dremel cutoff wheels, if you make a pass and then go over it 
again several times (instead of trying to hog all the way though in one 
go) won't even draw the temper of tool steel.

When I needed a blade for a hollow #55 spokeshave I cut one from an old 
saw blade and it works fine.
   I have a picture here somewhere but.................somewhere lol
