Strip time

My 200 year old, and listed, front door has been in a bad way for a long time.
I got fed up with the lack of tradesmen prepared to try and fix it; and because replacing it would require planning permission, and also be horribly expensive, as it would have to be made, I have started to try and renovate it myself.
Step one: strip the paint off.
A heat gun and 2 coats of stripper have started to shift it, but I'm leaving it overnight with a 3rd one on the remaining paint.
