in that case i may consider boxing in the cnc some how with an insulated cover and a small heater to keep the chill off... but the main function of this garage it doesnt need to be kept at room temperature... i've worked in open plan factories with big shutter doors open at both ends, i work outside alot of the day so i consider myself well adjusted.

yes i understand what the problems are with this garage but at the moment in time i'd rather not worry about me being cold and worry more about getting a nice place to do some work in and get some stuff built... this has come a long way from what i had last year, i literally shared an outhouse with the washing machine and had 3 barrels of homebrew on my only worktop in there... so all things considered yes it's not ideal but it's an improvement on what i had.

if i had my own way i'd knock it down and rebuild it and insulate it much better, but that i am afraid is a job for when i have my own house, i prob shouldnt even be doing this but i'll deal with that if i have to
