Chili, I emailed the guy at Dairy Fab and asked him this question and he said the only concern he would have is what I said, the sanitary issue. Particles of crap getting in there. The problem with the old style, as I made, is tentioning the wires is almost impossible. I won't go into the specifics but I do retention them after soldering them on, working my way back and forth, anyway, it's very difficult as the frame bends a little each time. What I like about the mesh idea is that I don't have to cut 120 individual wires, they will always be tentioned to each other. The work then is easy. So I will come up with a price and take pre orders for the finished product and then make a test piece. I need to take pre orders as you said it's a $75 minimum order, the probelm is I talked to the company, it's $75 minumum on each pieces and I would need 1/4" and 1/2". I do have some recipes that call for 3/8" but I think that's over kill, 1/2" would work fine.
For those of you reading this I will reply to this post in a few minutes and give a price for curds knives of a certain size and will go from there as a general idea of price cost. I will repost this in the selling area, please respond to that area for a preorder and give the size you need, size of the frame and size of the mesh either 1/2" or 1/4". I've been manufactuering items my entire life so believe me when I say to take a ton of measurements to make sure the final product will fit into your vat. I always subtract 1/2" from each side to make sure the cutter goes through easy and doesn't bind. It doesn't need to fit perfect. Plus it probably won't cost more to have it extra tall, that way if you go to bigger batches you can use it for that. They will have SS handles if you want.
