I was primarily a hobbyist woodworker prior to retiring from full time work at the end of October 2017. While I did take a few commissions prior to that, it was pretty much "all for me". After retiring, I bought a CNC machine to add to my arsenal of Euro style machinery and other tools, including a bunch of Festool, and made it a formal corporate business. It was the best way to deal with taxes as well as allow for "separation of church and state" relative to liability. I still do a lot of things for myself including making electric guitars "for fun", but I've also enjoyed doing work for others. I should be clear that most of what I do for money is subcontract work with some exceptions. I much prefer things that way because other makers respect my hourly rates and it's a lot harder to come by end-customers who want the moon and are actually willing to pay for it. BTW, it's rare for me to do work outside of my shop other than on my own home. Again, with minor exceptions to install something that's built-in, etc.
