delta wet grinder- help!

I have aquired a delta wet/ dry grinder, a 23-700. Been playing around with a bit. Having trouble adapting the jig that came with it to my needs.
I used it to set an angle on an old chisel, I had to hot glue a block of wood to the darn thing. I am presently trying to get a nice even grind on a turning skew chisel, I again had to hot melt glue a block of wood to each side, to get the angles to work out. And it seems to be taking forever to get done.
Anyone have any luck making their own tool rest for the wet wheel? There is not much rigidity in the one that came with it.
How hard can I bear down on a chisel running on the wet wheel? I got so tired of hold the skew chisel tonight, I clamped it on the jig, loosened the base of the jig, than tied a weight on a rope, run thru a pulley, down to the handle of the chisel. (make sense? I hope) I than came inside, opened a beer, and started reading my newsgroups. After an hour of run time, I still do not have the shape I want on the skew.
Advice and ideas are hereby solicited.
