David, I too used brass shims to tighten a Parker. The following has some merit and worth watching. Go to the 7:15 minute mark: https://www.youtube.com/watch?v=O_gI3WX6Uww

I am still looking for an oversize roll joint if they are available anywhere - thanks - Dave

If you need an oversized roll joint I can make one for you

David,

As mentioned earlier in this thread. As well as in other threads if you search for the topic. I do stock oversized roll joints in various sizes. They are $125 each.

In order to know what size you need, The size of your current joint must be measured, and then you need to know how off face it is with a feeler gauge. This will allow me to know what size joint is needed to take up the slack.

Of course the joint itself needs minor fitting to install into the frame. And then the hook fitted tot he new joint and then the barrels fine fitted to the breech.

We have found the best way to take them up on face is to laser weld the barrel hook and/or forearm surface depending on the situation. Tends to be a cost effective option at about $200-$300.

I have used several of Dudleys oversize roll joints and in my opinion its the only way to rejoint a parker ,if that's where the wear issue is and its no more expensive than the other method ,(if I had access to laser welding my thoughts may change ) ....welding the hook is second if the first option is not viable
