I was under the impression that a spring compressor was not necessary for the HW95. I know for sure it is on the 97.

HW/Weihrauch HW95 rebuild
- Thread starter Bedrock Bob
- Start date
Think in terms of short spring I once heard, , maybe a soft suggestion. A . 30 coils of .125 wire x 780 with .300 delrin top hat fits factory guide like a glove.
.22. 15 to 16 ft lbs depending on barrel..
I’ve have been known to tinker.

You could probably do it without a compressor. Re-assembly would be a fight and things might not go together smoothly.
There wasn't much pressure taking it out (35 lbs) for very long (2-3") with the broken/sagging spring.
I'm putting it back together this afternoon. We'll see how much force it takes to get the genie back in the bottle.

Mine was dry!Should bebetter. I'm pretty sure those are the newer style HW seals, and every one I've seen on different posts are in similar disrepair..lol. Must be all the grease blowing a hole through them.

The operation seems to be a success.
I re assembled the rifle with the vortek kit. It went back together with no problems.
..........
If you can push it all in there without a compressor I'd like to watch. There was much more force against the new spring going in than the old one coming out. About 2" of preload and 40# force. A compressor is definitely the way to go. You could get it back together but the little dog that holds the "breech plug" in there could slip out putting the "square pegs" in there. A fixture to hold it is best for sure.
...........
I shot about 25-30 shots and it diesels a bit. Not crazy but a little smoke on each shot. After about 35-40 shots it diesels very little. Once I got the smoke worked out of it I set up the chrono.
I shot about 100 shots over the chrono. I had a few low numbers (smoky shots) but it settled nicely between 688-692. The last 25 shots over the chrono were within this range. Only a whiff of smoke once in a while.
Here were the last 5 shots over the chrono. Iron sights. Sitting in a lawn chair with elbows on my knees at 25 yards.
It shoots as well as it ever did and the shot cycle is much improved. The velocity is higher than it ever has been. If I can get 10k shots through it before I have to do it again I'll be happy.

It's a .22.
Now to re seal the gas ram Cometa 400. It's dropped 100 fps in 11,000 shots and is ready for some attention.

Looks pretty professional to me OP! Yeah, that spring was busted...didn't do your seal any favors either.
