In your experience of mating brackets to rifles Peter, what proportion roughly did you find collimated adequately "as found", and what proportion needed some adjustment of the mating surfaces?

[Peter Laidler]

If it meant telescopic optical alignment perfection, then I'd say all of them. If you mean how many were acceptable and could be adjusted optically via a quick tickle of the drums, then I'd say 10% - but that's just a guess. There was a bit more leeway in the range mode because by definition, the grat moves through 60 clicks/a greater distance down its travel from 0 -10 into the optical aberration zone. But it wasn't much. I'll have to look in the No32 EMER but I think that there was only a 5 or so click left or right leeway from absolute telescopic optical alignment for the azimuth or deflection mode

Thanks, I assume you only adjusted the rear mating surfaces on the brackets? I say that since the the front four surfaces appear to be impossible to modify and still retain the parallelism necessary for them to fit together without any play(?)

And would the pad surfaces be adjusted, or only the surfaces on the brackets? I'm assuming only the brackets, since they were a replaceable part?

[Peter Laidler]

Just think about it for a second Robert........, please - and keep it simple! First, what are these 4 mating surfaces of the front pad you mention? There are only two. Radially around the male part of the pad mounting spigot and radially around the female part of the bracket mating surface.

You adjust the front pad area to bring the mechanical/optical alignment of the tele and bracket to the right. Adjust the rear pad/bracket to bring the tele to the left. Packing or shimming out of a pad was NOT an option.

While we only dealt with service rifles, the same principles apply to making a repro which are fully detailed in the thread I wrote a year or so ago

Thanks Peter, by "four" I meant the two on the front pad and the two corresponding surfaces on the bracket.

The issue I was curious about was the fact that the front mating surfaces are not designed to allow any 'pivoting' thereon as they have to be exactly parallel to each other to even fit together do they not?

Anyway, it was just a tangential question on my part and the mechanics of adjustment those who are interested can probably visualize.
