Sorry for the previous off-list reply (I didn't realise I hadn't replied
on-list...) and thanks for bring it back.
In any case, have you considered something like a bow saw with the blade
reversed? Or a hacksaw with the blade reversed? It occurred to me that
one needn't roll the roll entirely across the blade; one could roll
partway, move the blade forward (or backward) then roll under the blade
again.
Clearly, I'm thinking still of a toothless solution. These ideas may
also be brainless; just tossing them out!
Best of luck,
Donald.
