A while back I saw a post saying there was a Diana Model 6 for sale on eBay. Not many people were bidding on it, probably because it needed new seals. I ended up winning the auction for a great price. I bought new seals and researched how to disassemble this old gem. New seals came in and I started the disassembly. Came to a halt when I couldn’t remove the cog caps. Seemed like they were epoxied on there. Put it away for a few weeks as I contemplated sending it off to David Slade or trying to remove them with some leather and channies. Said to hell with it and was able to remove the caps without marring them. Luckily the cogs were in excellent condition. 
Next, I Jerry rigged an old dewalt clamp to be my compressor as mentioned in one of the tutorials. Removing the spring revealed a decrepit front seal that was stuck to the front of the tube. I let it soak in acetone then used a sharpened plastic cleaning rod to scrape it out. Smoothed out any sharp edges in the tube, replaced the seals, applied a little krytox and buttoned everything back up. The rear seal didn’t look too bad but I replaced it anyway. I noticed it doesn’t have a parachute like the new seal.
Took the first shot and couldn’t help but smile as the pellet travelled out of the barrel with no recoil. Shooting a recoilless springer is something that must be experienced by every airgunner. It’s like a magic trick. You pull the trigger and it doesn’t even feel like a pellet came out.
I dont have many .177 pellets on hand but it’s showing some good accuracy. I bet it could get even better with the right pellet. Here’s 5 shots at 15 yards with 10.3 JSBs. Shot off a split log.
None of this would’ve been possible with out the knowledge shared from @Motorhead, @Feinwerk, @marflow and @Bigragu. These guys shared the tutorials and tips I used to get this done. Also, thanks to the guy (sorry don’t remember your handle) who posted about it being on eBay. Without that post I wouldn’t have this unique piece.
*don’t know why my pics are not coming out.
