I have a few Beemans (R7's/HW50S/HW35) and Weihrauchs I would like to open up. I have the skills, just don't feel like building one myself (what used to take me 30 minutes to do now takes 3 days and a few do-overs).

R7 has a light preload so these could work for holding and aligning the small end block screw. Not sure if the older R7's use that screw but should work in either case. Just be sure comp tube doesn't roll out on you while compressing.
On the 50's (and R9's) I place a rag on the floor then a P1 seal that is smaller in diameter on the rag then fold the rag over the seal to prevent slip and slide while turning the end block out of, or back into the locking tabs with manual down force..no compressor required for these.

For my springer disassembly/reassembly I use a padded Groz sash clamp that I bought at a WoodCraft store. Solid metal construction with a long jack screw to accommodate long preload if needed...........

I have a SunOptics compressor that works pretty well, although a little fiddly to setup. No idea if they are still available.
Personally, there is no way I'd use one that mounts on the scope rails. That's a disaster waiting to happen IMO.
what length is youre? And, do you have a pic of the varrel end of the receiver in compressor? THanks...
Mine is 50" long.............

Since the clamp is steel and cast iron I wrapped a foam sheet around the bar and have used the plastic cap in the lower right hand of this pic to put tension on the breech plug when tightening..........
I've also used a thick felt disk to put tension on the end plug when tightening...........
Ooooopppsssss.......forgot the "barrel end"...........
Thanks, they're like driving classic cars. Vintage American Iron. Here's another one of mine. I've used my lathes as a spring compressor too.
This is as close to a new machine as you will ever find. I got lucky. It was hidden away many years before I got it and restored it. Was left unused. Some small parts were missing.
Use the tailstock quill to compress the spring.
More than one way to skin a cat.
made this one out of scrap this week. ordered a new R9 and Hornet kit last week. Fedx is the worst.
@1hp Like it, but not sure how do you fix the rifle action to the compressor.

Question is not answered yet, I guess. ?

no universal action end. have to fab or mod as we go. making a mid-rifle fork type rest. also use leather or rubber to protect rifle.
And, I guess nobody here makes and sells home made spring compressos like I have seen... Lots of great suggestions, thanks.

I did the exact same thing. Make sure you pad the bottom bar so as not to scratch the compression tube and barrel. You can see that there is some padding shown in the photos by @nced. Also, it is a prudent measure to make sure that you secure the action of your airgun on the spring compressor.
Thanks for all of the replies.I have enough junk around here that I can fashion something to work... The sash bar clamps look like good candidates... I remember seeing one made of wood with part of a c-clamp bolted to it, that is probably what I'll go for.
First up will be San Rafael @2. I need to see what is going on inside of it and give it a lube tune.
@jacob-sumner I have seen on youtube a guy do a springer take down using his cars tire jack, worked like a champ.
IMO people overthink this. You're not changing a coil spring on a car strut. Even a magnum springer hss what, and inch or two of preload? The main benefit of a compressor is it frees up your hands to insert pins or screws. I made mine out of a large C clamp I cut the end off. It's pretty self explanitory.
@limbshaker I finally watched that nightmare video, I was waiting to see that thing going through a wall. He sounded a little nervous too.
Don't laugh. This is the most versatile and easy to use spring compressor I ever had.

The jaws are padded so it doesn't mar the metal. I used the 36" length for everything.
