Nicely laid out shop Greg, mine used to be as tidy as that, once upon a time.
Be careful with kerosene heaters, they produce as much water as the amount of fuel they burn, that is why they are popular with gardeners in their greenhouses, less watering to do. You are liable to start to suffer corrosion and wood warpage.
I use a very small electric oil filled radiator in mine, and on the lowest setting, once the machines have warmed up, it is a nice 60 - 65 degrees all through the winter and they only cost pennies to run, mine goes on in October and goes off in March/April.
BTW, as asked before, where is the lathe?
