Shop power - conduit & boxes or flush outlets and Romex?

[Radix2]

This is exactly what I'm thinking of.
My father is 80 and starting to slow down. Since my shop is (will be) heated, and his isn't, I expect some of his equipment to migrate to my shop. But I'm not sure what will be first - the mill and lathe that we own together? The welding gear? Sheet metal tools?

Unless I run 240 everywhere, I'll probably be making changes in the future. All the calls of "just do a little planning" are kind of annoying.

It really isnt a big cost to run an extra 12-2 across your wall to make 240v available at every box. Are these machines bigger than 3hp? 20A/240 covers most practical machines people have in home shops?

If you use Wago connectors, they lay in the boxes nice and make pass throughs less of a burden.
