    Default HW97 spring compressor/jig

    Hi

    Does anyone have pics or measurements for a jig I can build to compress and secure the mainspring safely and protect the rifle while disassembling my HW97?

    It has about 1000 pellets thru it now and remarkably accurate but it kicks a bit and still twangs a lot. I have a spring guide and a few other bits to play with...also considering a good polish. However I want to do it safely and without damaging the finish on the rifle.

    Any other suggestions?

    Thanks in advance.

    Yes, thanks. One of those is part of the plan I am forming. Ideally, I want to build the clamp into a wooden frame that holds the receiver steady.

    Thanks all for suggestions. Watched a few youtube vids and the HW97 seems straight forward with no jig really required...... but they are all for sub 12ft.lb UK springs. I'm not sure how much more force/length to expect from mine which runs about 15 ft.lb.

    Since the back end screws off, how does one restrain the spring ?

    Thanks

    No jig needed... just expect the unexpected and you will be ok.

    Just remember however, to be careful when reassembling. Ensure that you seat the back end properly before beginning to turn it in. The threads are very fine, and one wants to avoid any possibility of a cross-thread.

    A Sash clamp and 2 planks are awesome tools to have.

    No clamp required. I've opened many rifles without issue. As per bloods recommendation be careful about cross threading. Here comes a strange sounding solution and I hope I describe it properly - My personal method is to use the floor and two feet to secure the threaded end and then use body weight to slowly loosen and tighten the thread. Keep either end of the tube wrapped in old towels to protect the parts from getting scratched/damaged.
