m2 rf horizontal alignment

[ikiru]

So my m2 arrived and seems to be in good nick. The Horizontal is out on the rf though. I have heard there is a special tool one can buy or make to not do a hack job of turning the screw to adjust the rf. Anyone want to point me in the right direction? (a photograph would be great if there is a diy tool to be made).It would be nice to have this item in my bag for long trips away from leica repair people. I'm also looking for any other advice on this topic of adjusting the rf.

Thanks,
Jay

I watched a Leica tech adjust the horizontal alingnment on my m4-p's patch. He used a screwdriver. Actually two, one to remove the screw covering the allignment screw.

This page contains a good description on how you adjust the horizontal (and vertical) alignment:

It's quite easy to do by yourself if you're careful, and you don't need any special tools for that part.
The special tool is used for the vertical alignment on the newer models.

I posted a anotated photograph in my gallery to help confirm the infomation I found on the leica FAQ

screw 1 is the one that I must turn to adjust infinity focus.

screw 2 Is used to make sure that close focus is correct

screw 3...not quite sure... But I think I may need to adjust it. From what I understand it adjust the outward travel

When I mount a lens it is quite stiff (compaired to my friends recently CLA'd m2)
Should I do 3 first then 1 then 2?

Thanks,

Find something with clean, sharp vertical detail (like a building or a pole) that's at least a mile off (some people use the moon at night, that'd be great). A screwdriver can be used, but you will want to grind the blade at an angle so it's parallel with the slot when the staff and handle are on the necessary angle to clear the bottom of the body flange. And make sure the blade fits the slot intimately. The adjuster cam is very tight and an ill-fitting tool will slip and cause damage to the slot. A very little turn, just a couple of degrees, will cause significant adjustment so easy does it.

Unless someone has tampered with them previously (evidenced usually by damage to the slots) there is not likely to be any need to touch the other screws and doing so opens Pandora's box. It's usually only the infinity adjustment that goes out of whack. Once that's set, try a test shot at a measured object at close range. If it's out of focus then you can deal with the other adjustments...in which case I recommend sending it to a pro.
