How to assemble slot cutter router bits?

[Chris Padilla]

Me, I like an aircraft nut for these stacking router bit assemblies. It gives me more assurance that the assembly is not going to come apart in use.

Never heard of an 'aircraft' nut before and when I looked it up, I see that it has that nylon insert in it. I guess I never knew the proper name of these nuts!

Oh, yeah, put the cutter on so that the teeth cut when the router spins -- not backwards. No big harm if you do put the cutter on backwards -- it will just burn instead of cutting.

LOL! I just did that recently and wondered why it was cutting so poorly! DUH!
