One other point which is worth adding. Don't make your own bolts either..
There is a story [old wives tale maybe] going around up here in Canada about a fella who was
a true homebuilder. Made alot of his own bolts from high grade steel.. but cut bolts are a different monkey
from rolled bolts.. [even if they are from 4130 or some such] short version is that he's "headed west" due to a bolt failure.
FWIW
