Bought this blade and mandrel from Revain at the same time. However, the pavilion I bought was complete scrap and milled crookedly. So buying this blade was pointless. HOWEVER, from what I've seen of this blade, it appeared to be of very high quality. I just can't trust import thorns on Revain to get it working. So I'll probably just buy the McMaster-Carr combo instead of knowing it works.
