Diana Bullseye ZR mount O ring placement

[HectorMedina]

Senior Medina,
If Diana could engineer the ZR mount to incorporate four bronze bushings in the aluminum housing at the exit points of the sliding rods I believe that would be a solution worth pursuing. That would be a cost effective modification in my mind without creating a whole new design.

Drill out the four points and press in four bushings for the rods to slide in.
Maybe a $120 mount instead of a $80 mount? No drilling or set screws needed by the perfectionist shooters.

Myself having worked for the Germans for six years of my career I'm sure it would get some pushback. Especially from the engineers with the last name ending in ski. LOL

At present, the effort has been to get the maker get better and better at keeping good tolerances and quality. The current crop is not bad as far as hunters and plinkers are concerned (which covers 95% of all airgunners).

Bushings would be a good solution, but what happens with wear?

Screw adjustable buttons have the advantage that you can take up the wear, like any gib in a machine tool would allow you to do.

I'm making a few Accurized ZR mounts per month, so I know the demand is there.

It's not the first, nor it will be the last, time that DIANA does not pay too much attention to my suggestions.  ;-)

Thanks, keep well and shoot straight!

I found some 6mm ID X 8MM OD bronze bushings. I'll install when I can devote time to this. I wanted to be able to screw them into the mount for easy exchange of worn ones but that is proving too difficult. Press in bushings will have to suffice.
I am also working on a two piece barrel tuner. Lower half secures the barrel shroud and has outer threads at the end. The upper half is of larger diameter, has internal threads and screws onto the lower half. Looks like a proper tuner IMO.

Yes it does.
My battle with "adjustable" tuners was unsuccessful because the vibrations of the action. No thread proved to be up to the task. Fine ones, coarse ones, acme, whitworth, all of them ended "dis-adjsuting themselves with use. AND it was that "self-dis-adjusting" that caused the demise of the commercial one.
Maybe you can solve the riddle, hope you will.

Keep us posted!

Sorry, I had a couple major family events happen so haven't been able to devote any time to this project.
Hector, you have to sometimes think out of the box to solve a problem.
