Hey,I have the same mount on my D54 as the one you posted on the last pic. What happened to it? What do you mean exactly it " ate it"?
dtdtdtdt, I never thought about the set screw in the aluminum tab...go going
I'm wondering me if I should build my own Bullseye mount with a complete set of miniature guideways and recirculating ball bearings. I already have the set and think I've to sacrifice a one piece mount for taking the 11mm base and screwing it under the guideway and the two collars on the bearings. Just asking myself If it should be completely free of movement back and forth retained with two springs on each side. It seems promising and almost no free play at all + you can put some torque on it without seeing it moving.What I don't like about the ZR mount (I've one) is its flexibility. You see it when pulling the scope when turning something like the zoom or AO. It's just going sideways but when doing a full cycle, it seems it goes back to place.The other thing I don't like is the impact on the cone when coming back, it still gives a shock to the scope. I would like something totaly free of shocks. When you buy a 100$ you don't care (maybe a bit), but when it's about 300-500, it's something else... I've seen that when tightening the grub screws retaining the rods, you can actualy adjust the remaining free play and making them tighter. Maybe it's possible to remove the cone if its done and only placing o-rings for cushioning it. I need to experiment all this stuff.
Use whatever units you like. But please don't quote velocities in furlongs/fortnight. I like to keep the numbers shorter for ease of typing.FYI. 259m/s = 850f/s = 1,557,818.18 furlongs/fortnight. Interesting ideas of the ZR mount, I hope you will keep us informed!!
A furlong is 1/8 of a mile and is now used only in horse racing. A fortnight is two weeks and was used in the UK for centuries. The unit, furlong/fortnight, was only used, to my knowledge, to teach first year chemistry students unit substitution in small Kansas colleges like the one I graduated from. It was important as a teaching tool during the era before SI units became more or less standardized in scientific fields to aid in teaching how to convert from one unit set to another. It can also be used to measure the running pace of Olympic-class snails. You how have a new UBI in your collection. UBI = USELESS BIT OF INFORMATION
Hector,I'm also on a French Airgun forum, Yep, Strasbourg is not too far away, I'm more in the middle near Colmar (but not in Pennsylvania lol).I've had a Hawke Vantage scope with the crosshair being broken up from the recoil and a poor Stoeger scope with the erector lense geting lose from the recoil too. I'm a bit vaccinated from the fine hairy crosshairs. That's why I like more the Airmax family with a laser engraved lense.I like a lot your idea about the shortened mount.The grub screws are those you mentioned, the 4 ones in the rings. By applying more or less torque on them, the free play gets reduced further (but not too far or it jams).About your maternal Grandfather, it's nice to have such a souvenir and being able to tell about.
