Well, tonight my buddy Gorden and I had a couple of beers and decided to do a static test on one of the arms I cast. ( beer, power tools, cast aluminum what else do you do Friday nights!)
We chose the worst arm I had cast so far
This was after cleaning up the piece on the mill than drilling and tapping the arm
Well, it was the worst looking arm...
This picture shows how deep the bolt penitrates the arm
We than began to load it up
75Lbs This was the one with the sink holes!
I have to tell you, it was SCARY! Weights, beer, running shoes...I have been told my toe will be fine in a couple of weeks... It has now been three hours and they are hanging there, so I think these might be pretty strong.
Initially I wanted run the test to failure, but I , I , these are my first arms, I worked so long on them, I just couldn't destroy it.
the PIIIs weigh less than 300lbs, twelve arms, about 25 lbs static pressure per arm.
I hope you have had a good night...
Sarah, does this answer your questions?
More to come...
