I completely disagreed and suggested that the reason people buy this small evaporator is because they only have 50-75 trees but want a professional grade (but smaller) evaporator to work on!! There is no question that we would have gladly paid that money for the 1/2" insulation to ensure "fit and finish".
I'm stuck for this spring but will likely rip everything out this summer once I get a reliable lead on where to get the proper 1/2" insulation. It's really too bad, this arch is so well engineered, crafted and assembled. Selling it with the 1" insulation really takes away from final product.
Oh well, as long as it makes steam we'll be happy.
Why would they not just sell you the 1/2" originally then? $150 is peanuts when your buying an evaporator. My guess is they just don't have or can't get the 1/2". What CDL location did you buy this from? I would get in contact with someone at CDL and find out what size the arch was designed to have. When spending big money on something that is sold by a huge and reputable maple dealer that has been in the business for a long time you expect that they can get a hobby arch right.
You can't go wrong using larger insulation though. It will hold more heat and sides might not discolour as much. That's one way to look at it.
