If you’re using one tool + dust collection at one time, you could quite easily get away with a 60A service. You’d just need to replace the panel with one that is a) not a crappy fire hazard 1950s relic and b) roomy enough for the breakers you need to run.

You don’t need separate 20A breakers for the shapers unless you plan to use more than one of them at the same time. With 20A receptacles, you can put more than one on a circuit. Assuming single person use, you realistically only need two 240V circuits – one for tools, and one for dust collection. That leaves you plenty of capacity for 2-3 120V circuits for everything else.
