Hello all! 14 year long machinist/millwright here. Tool and die, oil and gas, automotive, manual and CNC machining, and machinery repair work. Have 10 years experience running HAAS mills. I've got a small side business that I have had for 11 years now selling some automotive parts that I designed and have made for me by a machine shop in a different state. My business has really exploded and the shop cannot seem to keep up with my orders and this corona stuff has really killed me getting parts. In a of couple years I am looking to move and build a new home and shop on a acre of land I purchased last year that is closer to the plant I will be working at. I am wanting to purchase a HAAS mini mill, put it on 240V single phase and do a 30x30 detached insulated/air conditioned shop behind the house. Its hot here in texas and I want to keep this machine cool and dry. I mainly machine aluminum with very little 303/304ss. My questions are what type of air condition and insulation setup are you guys with home shops using to keep things happy? When I get ready to build, im going to try my best to get 150-200amps of service to the house and put 60-80amps of service to the shop for the machine plus air compressor and support equipment. Any other suggestions for garage doors, weather stripping, etc.. please post up. I was thinking about a 18K BTU 19 seer split system wall mount ductless unit for AC? We are still in the design phase of building, so plenty of time to tweek things before concrete is poured. Appreciate any help/input.
