    At risk of upsetting the vast majority of people who think a springer should be heavy, I decided to challenge myself and build a lightweight TX, that incorporates some of the alterations I have made and tested over the last few years , my aim being a low recoil/surge accurate light TX.
    So I have manufactured an aluminium action,
    spec: All ally action, under lever, & shroud, Ally and steel 22mm comp tube , skirtless Piston (utilising a modified aussie Hw 45 seal) Decided to go skirtless to give me a wide choice of spring, thats not to say it will stay that way! 90mm stroke extremely short ( 4mm) transfer port, that has an internal o ring in the end of the comp tube , the comp tube has a steel insert that sits flush to the barrel when cocked seating the pellet , and at present a cut down Mark 3 spring,
    Under lever has magnetic catch to minimise interference with the barrel, I think that's about it, oh the barrel, is a cut down CZ s200 making it 2" longer than a standard one , fitted into the new shroud makes the gun 20mm longer than a standard full length
    Shot cycle is nice and soft very fast , early days yet only put around a hundred through it .
    It weighs 7.5 lb. in the beech stock, standard is in the region of 9lb.
    Further this is going to be my FT gun if all goes well so I have made an ally adjustable target stock to go with it that is very light, no pictures of the stock yet as its away being powder coated , Pictures to try and show better what I have been up to , hope you like it.

    WOW, looks very nice indeed. Im jealous of you having the skills and tools to do something like this. Link works for me, perhaps you need to have a google account/be signed into one to see?

    Wow indeed - what an excellent achievement Nick :cool:

    While I'm firmly in the "mass is good" catagory when it comes to springers I can see you motivation to go lighter.

    Any idea how efficient the 22mm setup is? What piston seals are you using? I always thought the replacement aussie seals for the HW45 and 25 would be a good bet for such a conversion.. would love one myself but never get around to pulling my finger out...

    I think this deserves a lot more attention than it's getting!

    Very impressive!

    I'd be interested in finding out how it shoots.

    Steel is 3x stiffer and stronger than ally (generally speaking) did you make any allowance for that?

    Early Whiscombes were all steel, the newer guns were ally with the more highly stressed components made from steel.

    Titanium is probably the way forward due to strength/stiffness ratio but a pain to machine.

    Keep us posted on how you get on.

    Did the old Webley Eclipse have an alloy cylinder? I suppose mounts chewing up the rails might be a slight problem. Maybe you could get around this (and make the action stronger through not cutting dovetails) by having a raised BSF-style set of dovetails on a rail attached to the cylinder by 3 or 4 screws.

    Using the aussie hw 45 seal with a couple of modifications, no idea how efficient it is but it does shoot very softly for its speed if that makes sense :confused:
