    Original Model 35 re assembly

    Does anyone have a trick on how to re assemble an Original/Diana model 35.
    i have tried and tried to get the two tubes to stay put.
    If you've ever worked on one of these, you will know what i mean.

    Is there anything on these on the "Idiot's guide to airgun strips" over in Collectables?

    There might also be some tips on Tom Gaylord's Pyramydairblog.

    Long time since I worked on a model 35. There was a good spanish language strip down on youtube I used. Couldn't find it, but found something similar:

    What exactly do you mean by 'two tubes' (as against 'two soups'?ldconfused): Do you mean the 3 ball trigger? There is info on the 3 ball trigger in the Collectibles guide for the Original 50 that will apply.
    Cheers, Phil

    Model 35 Reassembly using dummy pins

    From memory, I made two short pins to hold the two 'tubes' together and held the balls in place with grease.
    This assembly was put on the end of the spring guide and pushed into the main cylinder using a spring compressor until the ends of the short pins were visible through the holes in the main cylinder.
    Then the proper retaining pins were pushed into the holes which pushed out the short pins out the opposite side,

    Hope this helps,

    Best regards
    Bill.

    Original Model 35 re assembly

    I've just done one funnily the other week, as with the 50 the secret is to wind in the spring compressor with a small socket in the end of the inner tube between the end of the compressor to allow the tube to turn, wind it in slowly a few turns at a time & use a flat screwdriver to align the two tubes as they want to turn apart as you go, when you get the pin holes in line pop the rear pin in first till you get the second one in then refit the trigger & end cap. make sure you get the outer tube in the right way too not upside down too .Oh & grease the 3 balls holes well to stick them in place before you start too. it's really a three handed job tbh so a competent mate to align the tubes as you wind in the compressor would be ideal. The one I did had the one of the tabs at one side the trigger pivots on bent out so i had to tap it back straight to get the trigger pivot pin in so check they are parallel before refitting the trigger pivot pin. An airsporter spring brings them up to power i found but a little harsher to shoot so i'll be fitting a weaker one soon .

    I rebuilt a gecado 35 over 40 years ago but can remember having to use a strong thread and some real heavy grease for the 3 ball trigger all I can remember
    Strange how my avatars and settings keep getting either deleted or messed around with
