I have used linoleum on both my vandercook 4 and chandler price 10 x 15 for years. I found the easiest thing for me is to use unmounted linoleum and secure it to a wooden base with rubber cement. I reuse the wooden base on all linocut projects and peel off the linoleum to store it. I start with the old gummed-up base, put a layer of rubber cement on the linoleum and let it air dry for a few minutes while I get the ink ready. This leads to a nice, positionable hold. Although it is not as scientific as it could be, the makeready has been consistent throughout the years. I use packing under the linocut and wood base to make the assembly
type high and try to leave the rest of my packing alone. I probably could do better with a nice metal base and some good note taking, but it has worked well for me.
