Hi Ron
I would be coating paper that is mounted to aluminum, and I could vacumn the mount so it would not move as you draw the blade over.. I don't think I would ever go over 30 inch but given that the paper would not move, and I actually am crazy commited, and I think your application kicks ass , do you still think it is possible for a couple of units to be made. There are more people in my group who would use this so we may be able to pull it off.

With film, that is not a real problem as you see from Jim Browning's web site. So, to date, the widest that I coat is 16" for 16x20 paper and I only have one of those blades. It would cost nearly $2000 but I have not costed it out so don't count on that price. You see, when you cut stainless bar stock, it warps and bends which means that the material has to be straightened and then polished to get the 0.001" tolerance that I need. This just about doubles the price as length goes up.

Also, the 16" blade weighs about 1.4 kilos, so a 36" blade would probably weigh in at about 2.8 kg. Have fun with that! Wow.

And, a 4" blade is not 1/2 the cost of an 8" blade. The cost goes up in a non-linear fashion.

So, with this method, unless you automate it somehow, you are out of your mind!
