About GarageShopCalc

GarageShopCalc exists because the question every garage woodworker, machinist and welder asks is the same: what actually fits? A one-car bay, a two-car bay, a car that still has to come in at night, a 120V circuit and a budget decide almost everything. We build calculators and drawings around those constraints.

How we make money

This site earns commissions as an Amazon Associate and as a Grizzly Industrial affiliate when you buy through our links. That does not change the price you pay. Grizzly sells direct and many of its machines are not on Amazon, so most machine pages offer both buying options and say plainly when one is the better fit. See the affiliate disclosure.

What we are not

We are not licensed electricians or engineers, and we do not test machines. Everything is researched from manufacturer listings, published code tables and owner reviews. Read how we research.
