Hi Ken,
Instead of mounting my camera directly to the Jackar adapter, I use a Slik quick-release system (the DQ-20). I mount the DQ-20 to the Jackar, and the camera to the QR plate. In order to make this work, I had to make two small mods to the QR plate.
1. On a stock QR plate, my camera sat too far back from the eyepiece, causing vignetting. So, I removed the mounting screw in the QR plate and enlarged the mounting hole into a slot. This allowed the mounting screw to slide forward, moving the camera nearer the eyepiece. I used a table-mounted, woodworking router to make the slot. The only tricky piece was figuring out what I could mount the QR plate in so as to keep my fingers away from the router bit.
2. Once I had the slot, the stock mounting screw no longer worked, because the folding tabs on the stock screw were obstructed by the side of the QR plate itself in the forward-most position. So, I replaced it with a 1/4"-20 socket-headed screw at the local hardware store.
Hopefully the pictures clarify the description.

Hi Dave,
Thanks for the quick reply.
I have the Jackar and had been wondering about a similar set up.
Excellent.
