Anyone using a Clark hollowing system?

[Bill Wyko]

I have one but haven't had a need to use it in a few years. Anyone else using one? It's big and I only need it on larger turnings so I don't get much use out of it. I'm planning on starting a large turning so I'd like some input from any users of it.

I've got one but haven't used it in years. I was hoping to get some tips & tricks before I put it back into use.
