Being always in search of a different mouse trap and needing a small project in the shop. And to keep peace within our marriage since this pandemic has promoted to much togetherness. I decided to improve on the spring compressor currently being used.
My main objection to the current tool is not enough travel when when removing or replacing springs in air rifles that keep gracing my doorstep.
I dug around in the metal pile and found an old bronze prop shaft I had purchased from our local ?? 100 miles away scrap dealer, thats what I get for living in the forest.
It looked like the perfect cantidate for a long threaded shaft for the tool I invisioned. The hacksaw made short work and soon the lathe was blessed with facing ends and center drilling said shaft.
I ground a tool for the square thread shape of the existing thread, set up the lathe and started cutting thread, made about 10 passes then got distracted which is easy for me at 76 and brain farted the thread dial and screwed up the shaft. Felt like a nincompoop apprentice again !! Back to the hacksaw and another piece of shaft and settled down to paying attention to the task at hand.
After finishing the final cuts I lapped the shaft and the piece it screws into together with 120 grit for a nice smooth tight fit, OK pretty satisfied that this whole process had taken 3 evenings when in my working shop I would of knocked this out in about 45 minutes and called it good, but that was many many years ago and much bigger and better lathe, old WW II Leblond.
Made a handle and assembled the tool, it looks good and will now try it out and report on its success or failure.

I used to use a pipe clamp like that, the drawback being the short threaded piece which doesn't allow for much preload. Looks like you did a great job. The only things I didn't like about using the pipe clamp is the small foot print of the piece where you butt up the end of the compression tube, the short length of the screw and no convenient way to hold the clamp and compression tube together to prevent the compression tube from slipping off and letting the spring fly. Never had an accident, but there was always a bit of a pucker factor involved when using it. Now I'm using the Sun Optics compressor and am quite tickled with it.

I'm a peaceful man and prefer the pursuit of peaceful sports. Those involving teams and balls of any sort tend to be deleterious to one's body and promote violence by both spectators and participants. The shooting sports, however, tend to promote self control and are peaceably participated in by those who know that their greatest challenge is their need to continually hone their own abilities.

Congratulations on a job well done. I have no lathe and would have no idea where to begin doing something like that. I did a bit of woodworking and cut down a cheap C clamp to arrive at a similar destination.

Paul, I use a camlock strap from our old whitewater rafting days to cinch the compression tube and clamp together, that way no chance of flying around the shop.
Yes Thomas, I would of done as you did but needed some escape time out of the house and out in the shop,
Your avatar pic, an old Royal Enfield or Norton Atlas?? or maybe an older Bonneville??
Again, Thanks to all for getting me back into shooting once more,
Steve
