Got the sides cut yesterday and finished welding today. Checked for leaks and filled it with sap this evening! I haven't started to boil yet, but will tomorrow morning (not enough sap to mess with tonight). I hope it shows a significant improvement. I went from 6sqft to 17.25sqft of surface area. I have a 3/4" port to weld into it for my new valve, but I have to do some cutting on the evaporator to allow clearance for it.
