Exactly Alan, we all have our reasons why we can't work on sets as much as we'd like to, if at all sometimes. BTW, my workshop is unheated and as you'd expect, due to gaps around doors and under roofing etc it is pretty much the same temperature as it is outside - sub zero at times. I use a Calor type room heater and it works a treat. Not expensive to run neither. Not wanting to sidetrack the thread into heating territory, but just a quick tip based on my experience!
