Im going to just get a block of 1 1/4" x 3" steel and start milling when its dont it will look like what im thinking. If I could design on a computer I wouldent be sitting here broke. LOL Im not sure what you have there but its cool that you can do it.
I would not recomend using bolts to hold any part of the bolt together especialy a weight all that coing backand forth coming to abrupt stopes ect is a accident looking to happen. that 24hr build scared me it got nurmious issues that can be un safe when it fails.
