That's tough!!!!
Know some that would say "Household tools" are nothing more than a parring knife and a old S.O.S. pad! /ubbthreads/images/graemlins/wink.gif
Others would expect a drill press as minimun (and that I'd agree with).
A lot depends on alot. :haha: Some can work miricals with a set of dremels, Exactos, and a few files and emmery. Others need a total machine shop.
Drilling and tapping, solder/brazing, and inletting can be a disaster to some,,, or a trial by fire for others.
Then you need to figure "expectations".
Back in the early '80's a friend and I each bought a CVA Kentucky kit.
He built his at the kitchen table! :: It worked well,,,, but looked like a $50 Special at Wally World.
I, being a toolmaker built mine in a shipyard;s machine shop during lunch and after (?) hours (sorta). Built-up the nose cap for one with brazing, Utilized a buffing wheel and compound, Bridgeport for pins, and a tracer for the butt plate. Engraved the thimbels, tang, guard, and nosecap. Also re-crowned the barrel, honed the bore, and made my own front sight. The 2 piece stock boast it's only a $75 kit (at the time), but, I'll bet I could get $55.00 for it! ::
