I have all the resources and skill to make a spring compressor but I simply use a furniture clamp on my RWS model 48.It works perfectly and I can spend more time shooting instead of building a special set up.I have also done it completely by the strong arm method while my wife set the pins that hold everything in place. That may not work on all rifles.
Avator, if you are logged in you can go to your post and use the Modify link to delete the content of your message(s).You could also modify the existing post and put a Warning in it explaining what happened. That may be of help to others who might be considering using that clamp.Sorry to hear about the failure and glad that you are OK.
I'll ask one more time, what is a "furniture clamp"?
