Don't do it......your going to kill yourself........it will break..........you'll do a left turn into a car........which will swerve into a truck..........which will go head-on into oncoming traffic and kill countless people.
To do this correctly,you must first buy a mill,then a rotary table,a clamp set,some center drills,drills......Then after your done,send it out for some stress testing,remember,suicide is against the law,since it will probable fail to any good lawyers standards,your going to have to redesign one to except drilled holes in order to pass the lawyer test.......then your going to have to bone up on your enginneering skills some,unless you want to keep making them and running them through the stress tests until one passes.......then and ONLY then is it safe enough to ride around with.....
So I wish you good luck my friend with your drilling adventures....be save and contact a good lawyer......sounds like your going to need it!
And people wonder why there is no work in the U.S........
