First of all, thanks for all the comments and good advice. The breaker box is located in the garage and there is no clear, open route to the basement and on to the shop. Here's what I am going to do:

Get an electrician to upgrade me to 200 amp service. Add a dedicated 20 amp and a dedicated 15 amp circuit to the shop. I'm guessing $1200 to $1500 for this and I suppose the utility will try to hit me up for the cost of a new meter.

In the meantime, I'm done ripping the maple and on to completing the new kitchen table.
