    Walther LP53 help wanted

    I would appreciate help and advice regarding my tatty old LP53 with a missing end cap and no rear sight that I wanted to cobble together as a plinker (possibly to be then passed on to my Grandchildren for them to use). It's in poor condition all over and not worth spending too much on (especially as I don't know if it would work if I did somehow or other find an endcap for it). Am I likely to find an original end cap at a reasonable cost (I've looked around on the net myself but no luck so far), or is it possible that (for instance) one off a Diana Model 5/6 might fit and I could cobble the LP together somehow with a few home made parts.

    Practical ideas would be appreciated thanks, but please note that the item is in poor cosmetic condition all over and all I want to do in the first instance is to cobble it together to investigate viability of doing a better job at some point in the future.

    Thanks, Vic Thompson.

    Maybe someone knows for sure what endcap might safely interchange but if not my two thoughts are try anything you already have to see if that works or secondly take a trip to a large stockist of parts & see if they can find you a suitable replacement., maybe a trip to Protek? Guess spares are pretty rare & it's likely to be expensive even for a breaker example.

    Part 27 here but sadly out of stock

    Maybe someone could measure the size and thread of a cap for you Vic?



    You may strike lucky with a cap off something else-----maybe a S2 pistol or similar? Im pretty sure someone on here would be prepared to make to a simple threaded cap and you could sort out a guide that is separate to the cap.
    Maybe if you know the thread, someone may know of a nut or something that fits something else-------wheel nut or pipe fitting etc?

    Any decent gunsmith should be able to whiz one of those up on the lathe, or if not a gunsmith a small engineering shop.
    The threads will be metric I assume.

    I did think about making one myself but it's just too much hard work. Regarding anyone else making one for me, the price would be prohibitive and might not be as successful as a proprietary unit anyway. Long since gone are the days for me when I could get one knocked up at work whilst I waited for it.

    Fresh ideas on the matter appreciated and particularly pointing me in the right direction to at least borrow one if not actually buy one. I myself don't have any real ideas left now as to where I might pick one up from.

    Vic,

    You know that one of the Weihrauch sights will fit the LP53.

    Thanks for the reply to my listing Steve, ideas regarding the rear sight get me half way there, but I'm still pretty stuck as regards getting a cylinder end cap. It's the usual problem for me, every time I come to look for a spare part (or two) to finish a particular job off, they're never available but quite often I come across things that I wanted ages ago but couldn't find at the time.

    Sods law says:
    When you've given up and ordered a new one at prohibitive cost you will trip over a secondhand one for pennies or find the one you thought you'd lost sat on the bench under something else...


    Just a note though, Diana Miod 5 end caps are totally different to the Walther LP53 so no use trying to find one of them to fit, they won't!
    Sorry I can't be more help, could possibly make one if I knew the sizes but I would have to charge and it'd be a long time before it gets to the front of the queue.
    BSA Super10 addict, other BSA's inc GoldstarSE, Original (Diana) Mod75's, Diana Mod5, HW80's, SAM 11K... All sorted!

    Hi Vic.

    As daft as this sounds, have you tried your nearest Hydraulic Hose specialist ?

    I find a lot of metric hydraulic hoses have a metric fine thread form in many different sizes so you could find the Walther has a common metric pipe thread.

    This is what you need in the appropriate size. :-

    Or even the nut off one of these would do it with a washer inside it. :-

    All the best Mick

    I thought something like that might do Mick.

    Standing back and looking at this like the sort of projects I seem to end up with, Id be trying to find out a few things. I assume Vic that you have no idea whether the gun was working or not before the end cap went AWOL?
    If that is the case, Id assume you want to roughly put the gun together to see if there any other problems?

    A couple of things Id try/ or appeal for are (1) if somebody actually knows the size and thread of the cap---which would help for looking for something like Mick has suggested (2) if anyone who has a gun lives close enough to you for you to visit or them to visit you, to try if their cap would fit your gun Ie, your threads are ok. (3) failing the above, if someone could measure both the OD and the Depth of a cap to give someone a clue , for if they have an unknown one in a spares drawer.

    I wouldnt be worried at all about a guide fitted to a cap as you could always sort something like that later.

    Im surprised someone hasnt got a dead gun knocking about which would give you a chance of putting something together out of the 2.

    Often with these things you do not want to spend much at all until you know you are in with a fighting chance of getting a working gun together-------then there is the problem of would getting the bits be dearer than getting a working gun.

    Good luck with it

    Vic has a cylinder cap from a Diana 6 that I sent him, and although it seems to have the correct diameter and thread pitch, he tells me has has not been able to get it to screw on as yet. He is working on measuring and cleaning up the threads, and so may be able throw some light on why they do not mate.

    As stated, John sent me an end cap off a Diana and it looks about the right size and thread, but I'm not very good at measuring internal threads at the best of time so there's scope for error. I don't actually know the manufacturers specification of the threads but I believe them to be M29 ? x 1 mm. The major dia of the external thread is 28.7 mm, and the major dia of the internal thread is 27.2 mm. My maths is rusty but to me that lines up more or less as the two threads being fairly similar, if not actually so. However, after looking at the Walther thread in better light than previous and after having cleaned it, I believe that it's damaged so my next task is to clean those threads up using a crude Die and check once more.

    It's amazing how much thought from various individuals has gone into helping me sort my problem out (which I'm very appreciative of), but I might be flogging a dead horse as if when the Walther thread is cleaned up the Diana end cap doesn't fit I'm still back to the stage where an actual LP53 end cap is needed.
