I think you are find for a “hobby” shop. Try not to run more than two large machine at a time and unless you are using electric heat there will be no problems. Be sure your wiring from the panel to the outlets is also up to the load you will put on it. I would suggest #10 wire all around but #12 will work on the 120v outlets. Be sure you follow the code and you should get a permit because if you do have a fire your insurance company may not pay should they become aware of wiring installed with out a permit.

Fortunately my shop is similar to a1Jim’s except it should have added more 240v outlets. I have had to add a couple using surface mounted cables )-;
