No32 Mk3 locking rings

[Merlin266]

Hi
Excuse the obligatory "this May have already been covered" comment, bit I'm having trouble with my locking collars to enable lead screw adjustment. I've used Peters book for reference, but the I can't undo the bstrds. When I try, I can't physically hold the drum tight enough to stop it turning while trying to loosen the locking ring, I'm not keen on letting the drum hit it's stop then try to undo it for fear of making a right balls up. Anyone got any ideas

The probloem is that in the past, and you're not going to believe what I am going to tell you next, but some dozy twonks super glue them in place.

The BIGGEST fault is equally dozy twonks using whatever they've got in their desk drawer to try to undo them. Use the CORRECT tool, allow the drum to go to the end stop and be a bit brutal. When they're undone, come back...........

Sturdy snipe nose pliers are mentioned, will the do the job, used carefully. I have an original tool for the mk1 scope which is no good for the mk3 as you know.

Now listen carefully.......... Sturdy snipe nose pliers, leatherman tools, grandads fishing hook remover and the sewing machine combination tool that granny had ages ago have never been mentioned by me or anyone else in our Instrument shops. You cannot use bloody snipe nosed pliers carefully because a) they're round nosed and b) the thing the round noses are meant to rotate are glued/jammed in. Just make the correct shaped tool!

Only my opinion of course. Others may have different ideas

Well that's had me chuckling
Anyhow out of my plethora of aircraft tools, I have found a suitable tool and managed to loosen them off. All is good
Page 77 in the telescope sighting no 32 says " Using a pair of sturdy snipe nosed pliers, loosen off the locking rings half a turn"
Have I got a pirate copy of your book

[Peter Laidler]

No, but since then I have heard many many tales of woe and I haven't updated it. But on the plus side, there's a picture of the correct tool in the back. In fact the problem has been so bad in the past that I have had to have great lengths of the lead screw locking rings machined.

Thanks for the heads up Peter, I shall probably make some tools to suit. I won't be tightening them back up to 3 white knuckles and a f@rt.
The scope is new to me and I just want to go through the bore sight process.
Cheers

Hmmm Peter require translation of a Twonk are they our version of a Dipstick - A few snags short at a BBQ - Coupla roo's missing in the top paddock - Uses a fork to eat soup TIA

[Peter Laidler]

Nearly right Cinders. A twonk is a few steps further on than a dipstick! It's the same twonks that get an old telescope that is totally jammed up and then flood the drums with oil. Then it becomes becomes jammed up AND misted up!
