A Trust Fund would be very useful.

now if it were a sideline for an already functioning Machine and welding fabrication shop,

rather than, or in addition to, as said a bike shop, that would help too..

so fixing Skidoos and such through out the year will help pay the bills ..
as the heavy machine tools , lathes and drill presses and such, don't come cheap
then you need a lot of other jigs and fixtures..

Schadenfreude, at failed machine shops for that stuff [or estate auctions]
