What if a job exceeds the capability of every machine you own?

There are rewards... and sometimes justification for new tools if you take some time to evaluate. Sometimes a simple high-effort solution is just fine though.

I did buy a new file. But, it is still a hand file. My elbows feel it for sure.

Heard of it, dun it, it is often more expensive in money AND time unless the shop is right next door.
