TipLap style tool sharpener

[Frank S]

A lot depends on where you are using them and what you need to use them for
the 5c uses a hollow draw bar where as stock can be passed through in the lathe such as a rifle barrel bore center guide can be adapted to the rear of the draw bar now the barrel can be held perfectly concentric to the bore in the lathe.
Obviously the R8 collects are made more to hold short stock or end mills and can be used either in a lathe of a millthat is the main difference to them in my opinion but if you put a dollar with it you still couldn't buy a decent cup of coffee now days
