Dang! I thought it was done with explosives.


The stuff I used for the bearing blocks in the spar where the pins go
is tough freakin' stuff, and made a mess of just about every sort of
drill bit we threw at it.

So, yeah, we did toss around the idea of det cord or shaped charges.
But sanity prevailed in the end.

Thanks, Bob K.


the landlord nixed the idea of using explosives.............I better
stop before echelon gets me!
