probably a Peter question but hopefully will be another means to understand the specifics about wheeling machine function.
The upper wheel is usually much larger in diameter than the lower anvil. Why is this? Does it provide a greater mechanical advantage (leverage) to smooth and shape the metal being worked? Does it provide better clearance for the walnuts in a blocked piece to enter between the upper wheel and lower die? Is it a combination of multiple things?
One reason I ask relates to the kidney wheel lower I ordered via Peter & Hoosier when ordering my anvils. It's approx twice the diameter of a normal lower anvil and I need to make some adaptations to use it in earnest on my HandBuilt frame. The lower adjustment needs to be spaced to allow enough clearance to install and it would be safer to use it with a deeper cradle than the original one on the frame. It looks like it has a lot of potential.
With much better clarity regarding full radius vs flats, I would also like to better understand the function of diameter ratios between upper wheel and lower anvils.
