A while ago I made post describing a mortar which was given to me. I believed it was a Hern. Rickk posts confirmed that. In my orginal post I made ref. to the drilling of the vent hole was a story in it's self. Rickk wanted to hear the story............so here goes.
Take a winter night, a garage full of motorcycle guys, lots of beers with funny names (I'm not a beer drinker), bring out a mortar for show and tell w/o a vent hole drilled, after a guy just got done showing off his new zillion volts, unlimited watts, mega tourqe new I can drill through anythilng battery drill. Now every group has to have an instagtor, ours is an PHD phycilogest. His low keyed comment " do you think that mighty nice looking drill really could drill through that?, (pointing to the mortar)
This of course causes a discussion, and conclusions based on beer more than anything else. So someone says I bet it cann't and then someones says I bet ilt can and now the beer betting, not the betting of beer but rather betting by those who consumed much beer.
Then the PHD (whose garage we were in) sez in a "stoned" voice "I just happen to have the proper sizsed bit right here(in his hand) of course this takes the discussion to another level. After a while it was decided to see if this new battery drill the size of which could havae provied enough power to lite upn the city I live in could drill a vent hole. "I though what the hell" what do I have to loose.
Well the guy with the drill revs it up like a kid with a hot rod at the stop light challanging all, then slips in the drill bitt gives it a couple of more rev's. A couple of beer filled guys hold the mortal on the floor, about as steady as they could wallk (they were not driving any motor vehs). The guy with the overpowered drill knelt down on the mortal with an unsteady knee and with a beer steady hand started to drill. He wasn't swayinhg to smuch and the bit was going through the metal, until it just borke nthrough. Yes, you gussed it. The bit broke.
Not to worry, was the concesious, we'll just drill the old one out. So a smaller bit was put in the drill and the "steady" drill crew went at it again, and yep, that bit angled off to the side of the broken bit and broke along side of it. O-Boy! now two bit's broken in the vent hole. The Stoned PHD guy who started it all, thinks the answer is a biger drill bit to drill both broken bits out. Well the zillion volt, mega tourqe drill seemed up to the take, but the orginal "steady" drill team was voted out, it was replaced by a less "steady" drill team. Well they wobble and drilled and wobbled and drilled until that bit borke off on top of the other two bits.
