Re: Crushing Aluminum
Yes, it will cause problems eventually, but if that's what you gotta do... well...
Use the largest possible bearing surface, and Not so it would encourage a direct break-off line.
I would use some quality gasket material sooner than rubber. Garlock?
The problem with aluminum is that it suffers from fatigue which leads to catastrophic failure. This was learned in a spectacular fashion in the aircraft industry.
Just my opinion... perhaps someone will have information of a long term success.
My goal is cheap, reliable, personal transport, below the tax collector radar. Fun counts for a lot!
