Rear Hub Puller - Churchhill Copy

["Alan Salvatore" <6parts@charter.net>]

A year or two ago I purchased a rear hub puller that was made by someone who
had copied the churchhill tool.
I have seen the church hill tool at TRF.
I had brought mine to a machine shop to see if they could take apart a hub.
He used an air wrench on it and could not get the hub to release.
I thought at TRF they used a very large socket wrench or torque wrench.
Is anyone familar with this copy, and what have they used to put enough
pressure on it, to get it to work.

thanks
