Since the base & plate would be subject to less shearing compared to a
Vandercook, the same base that works well on a Vandercook should work well
on a hand press.
The machining of the printing base will have to be very tight; specifically,
the parallalism and flatness of the base will be crucial to maintaining
consistent impression across the form. The non-magnetic base I sell, the
Boxcar Base, usually has less than 5 ten-thousandths of an inch variation in
thickness, flatness, and parallelism across their surface.
I should mention that Buntings are also very well machined. But an advantage
of the Boxcar Base is that you can purchase a much larger base for your
money. As an example, I just fulfilled a custom order of a 19.5 x 16 inch
anodized base for $580. This is less than the price of an 8.5x11 Bunting
Base. Tight tolerances are very hard to hold over such a large aluminum
surface, but this base turned out with less than 6 ten-thousandths of an
inch variation in thickness, paralellism, and flatness.
You can contact me off-list if you are interested in the price to
manufacture a base to the size of your press bed.
