About to try my first tune...

Hey scp52,

Go to the GTA Library on read the article from CDT on lubing a springer.  Also, see his article on making a spring compressor.

Since I have tuned a few of these Hatsans, here is what I have used for lube.
- Go to ARH (see James Macarri - GTA Mall) and buy the Lube package for $22 (Clear Tar, Heavy Tar and Molly) - also buy his piston seals ($12).
- Go to Amazon and buy some Super Lube w/PTFE  $9
1) Use Heavy Tar on main spring only.  Use Molly on spring ends.
2) Use Molly on piston seal and 1" below (roughly) and use molly on 2" of other piston end/slot.
3) Use Clear Tar on all slots and pivot points.
4) Use Super Lube in compression chamber only.
5) Make a batch of Gene Sunday's Mystery oil per CDT article for trigger lube.

Use all lubes sparingly!  My guns all dieseled (sometimes badly) for about 100 shots w/very high velocity and occasionally a bang!  Just clean the barrel often with goo gone.
 
For $31 you will have a lifetime supply of lubes for your guns.

I'm a long way from being a Pro, but My two cents..........

Hey Kirk... Ya got me wondering here...
Ever since I got back into airguns and joined the GTA I've heard that alloy pellets, desiling and dry firing is not good for a springer. And I'm not questioning your methods. But, wouldn't firing a gun like you are describing 100 times be hard on it? I'm also a long way from being a pro... I guess that's why I'm asking.

I was being lazy when I posted the above -> yesterday, (I copied and pasted) from one of my June 2014 posts.  At the time, I had just finished tuning (7) Hatsan 95's and (1) Hatsan 135 at the same time, and was reporting on the results. 





My overall road map in tuning these guns was from CDT  http://charliedatuna.com/Airgun%20Info.htm as no one else had a play by play account written out about air gun tuning. This was my first foray into shooting/tuning break barrel pellet guns and I thought I should use the Master's methods.
So I would have to say the methodology was sound as it gets, but maybe my implementation was flawed, learned by gut instinct, working on other mechanical projects.  When CDT said use "sparingly", I guessed at what that amount was.

In retrospect, I used too much Superlube on the insides of the compression chambers; most of what I consider dieseling was just smoking (it really stunk too).  Out of all 8 guns, I probably only heard loud bangs from 5 of them (small explosions) total - usually on the first shot from the gun.  However, all guns settled down to be fine shooters -> never had a problem with any of the guns after the initial 50 to 100 shots.

So, to make a long story short, my above post represents CDT mythology verbatim, except use less Superlube in the compression chamber & less Molly on the piston than you think.

The first attempt is now on hold...ARH sent my order, got it today and opened it to find my spare seal and a small jar of moly paste instead of the jar of heavy tar I ordered. Already have a jar of moly here but looks like I may end up with 2 unless they want it back. Probably be Friday before I get an answer to my e-mail.

Keeping an eye on this post.

I too am about to do a first tune. Pyramyd Air has a 6 min video on a tune and BB Pelletier did an 11 part article that's very detailed you could check out.

My tune will be for my Hatsan 125 (Walther Talon .22 in name). Have seals and such coming. Don't know if Nitro ram in it is damaged and if so undecided if I'll put in original spring or try to find a place to purchase a vortex ram.

Best of luck on your tune and looking forward for your photo of process.

Garrett, good luck getting Hatsan parts anywhere in the US, they have a big thing about liability issues and owners doing their own work. I have come across a couple websites in Europe that sell Hatsan parts, the Vortex rams included and supposedly ship to the US if you want the Hatsan Vortex gas ram, this one is in Poland:
