cam bore bars

[PEPPE]

There is plenty of posts about mains line bore bars. Little informations about cam bore bars.
which ones are the better? what about feed mechanism and adjusting of the cutters?

Never used one, only know to check that my case isnt cut for em, or that I ahvea mislabled box of bored cam bearings masquerading as stds.

I did once use a tool for "boring" the middle cam bore back to std size if the webbing has started to collapse from age. that was hand fed, just chuck it in a drill.
