lol Well, based on what I see so far in your design, it looks like it will work flawlessly. Nice solid parts. Once mounted onto a solid base, your sheeter should work perfectly. Will you post detailed/printable plans of your work once you are finished, so the rest of us can have an easier time constructing our own from the fruits of your labor??? LOL
Also, are the disks with the off center holes, rotary cams of some sort for thickness adjustment? Is your model a replica of the manufactured one that you posted ealier? IE: Is it the same design in principle? Will you put a finish (paint, laquer, powder coat, etc) on the steel at all once you confirm that your machine works the way that you want it? Are any of your parts stainless steel? Would you prefer or upgrade to stainless once you have confirmed?
I can't wait to see the finished results.
