    I see, like that is it, as soon as I make a horrid comment about a HW35 and you're all over it but when I work my fingers to the bone compiling a list to help all fellow mankind, you all of a sudden get distracted, well I'm afraid to say that I'm most upset with you young man

    I shall now no longer be getting distracted by HW35 threads and will be putting my ill informed efforts into BSA threads instead.......and as that's the case, you may not hear much from me in future

    Fear ye not, young Pete m'lad.
    The next gun I'll be having a tinker with is that little Supersport that you so kindly sent me the two sprngs for.. The power's a little close for comfort. Setting it to a lower level should improve its firing manners a tad also.

    Bloody hell, I thought you'd already done that one or is this a second visit?

    NO- OD - ID - Wire- Coils- Length

    01- 21.0- 14.5- 3.2- 31- 280
    02- 22.7- 15.5- 3.6- 30- 291
    03- 20.8- 14.7- 3.2- 34- 304
    04- 22.6- 15.6- 3.6- 28- 252
    05- 19.0- 13.1- 3.0- 32- 290
    06- 19.7- 13.3- 2.9- 39- 341
    07- 20.0- 13.8- 3.3- 30- 255
    08- 20.0- 13.8- 3.3- 34- 295
    09- 21.0- 14.7- 3.3- 27- 280
    10- 21.0- 14.8- 3.1- 27- 230
    11- 18.8- 12.8- 3.0- 31- 230
    12- 18.9- 12.6- 2.9- 36- 295
    13- 19.4- 13.0- 3.1- 39- 340
    14- 22.7- 15.4- 3.6- 37- 358
    15- 17.5- 12.1- 2.3- 33- 254

    All measurement in millimeters.

    Hope it helps.

    cheers

    Pete
    Well I've just received a no8 spring and measured the ID and it measures 13.3mm at one end and 13.4mm at the other but looking at the list, if you take 6.6mm (2 x 3.3mm wire size) of the OD of 20mm then that works out to be 13.4, so I'd say the list is wrong, I'll correct it now.

    Pete

    Spring recommendations for specific guns are not always the best option. Several springs may be recommended for a gun but what is reguired is one that is the best fit inside the piston. If there is too much gap between the piston and spring a severe twang can be the result so beware and always measure the piston inner diameter before ordering a spring.

    I credit the members of the BBS with enough intelligence not to recommend a spring as being suitable for a particular rifle if it caused a 'severe twang'.
