    Hi Mick

    Was a TX piston with a 30mm head ever an option?

    There is probably a fundamental reason why not but...

    Cheers
    Matty
    Opportunity is missed by most people, because it is dressed in overalls and looks like work.

    no

    he's just nicked a TX piston rod... And Pro Elite piston is non-rotating, in case anyone is wondering (30mm)
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    Just Hammerite it and get on with the build...

    Nicely done - looking forward to the end result, mate.

    Don't worry, Craig, the new bluing setup is working that well that I've boiled twice today already and if I don't get to boil later I'll have to shut it down for the night.

    BTW Cheers for the latchrod, and I'll machine you up a piston body ASAP.




    All the best Mick

    Have you considered a piston without bearing by the piston seal?

    As with many break barrel guns, when you cock an HW35 the tail of the piston is pushed upwards and the nose of the piston tends to be forced downwards, so the use of a front bearing keeps the piston parallel in the cylinder.

    No rush at all mate, get yours all sorted first and enjoy yourself.

    What are the advantages to having a fully rotating piston?

    At this rate I might be assembling it sooner rather than later, Craig.

    Yesterday morning :-

    This afternoon :-

    I did cock up a bit last night as I rusted too long and got some pitting on the underside of the action along the cocking lever slot.
    As it won't be seen when the gun's assembled I just bid it bollocks and carried on with the process.

    I'm hoping to have it up and running ASAP as it only needs assembling now, but I've got a little waylaid again.

    I'd never had any success with fume bluing in the winter months until I cobbled together the heated wheely bin I used to rust this 35 cylinder, so I thought I'd go a little further and make something permanent.

    I'm going to fume blue my next project while I'm assembling the 35, now the next gun's a .177" BSA club special standard which has the longest action of any of my guns, so I've set to and built a heated fume bluing cabinet long enough to fit that action in. :-

    In the bottom tank is an electric oil filled radiator with thermostat control so I can adjust the temperature, this warms the underside of the B&Q planter which is set into the wooden top of the bottom tank.
    The hinged lid is made out of thick timber to act as insulation and also to give weight to compress the B&Q draught excluder sealing the lid to the bottom tank when closed.


    And it only cost me £16.75 in parts.






    All the best Mick

    Good question, Matty, but the answer is no, it was never an option?

    To use a TX piston I'd have had to machine the front off the TX piston and then rough machine a new 30mm piston head for it, then weld the two halves together, and then machine the piston head to final size.

    Machining a one piece piston body is a piece of piss when compared with the above.





    All the best Mick
