Ok. I thought there were updated parts to accommodate some of the issues.

So, running stock class is probably out. I have both stock and vertical feeds, so its not really a problem. Or I could run the stock feed with a bottomline and reg.

Is there a disassembly diagram anywhere? I don't remember getting much with my marker....but that was also years ago.

The video is about all you gonna get in term of "guide"

And forget about finding spare parts ... I made/modified what i needed to get mine up and running.
I would love to get my hand on a dead one to try to make parts for them ... but that is likely a long-shot/pipe-dream ...

I'd definitely be interested in picking one of these up someday...I remember there was a time when people were ditching them for like 50 bucks. Never seem to see them come up any more.

Good to know adjusting the internal reg all the way in can allow you to bypass it and use an external regulator.

After searching through some old save files i did find this...

Metadyne Manual3_1-1.pdf

Metadyne Manual3_2-2.pdf

I have the 35 pages but the file is too large to upload... any suggestions?

[XEMON]

Awesome!

Public link google file would work.
Shoot me a PM if you want help with it

I had taken mine apart a while back and forgotten to put the reg all the way IN, I had it OUT and was like "WTF, why won't my junk work anymore".

Lol.

I just solved my breaking/binding issues by cutting down my homemade detent a bit. Seems to have solved that for the moment. The balls would be squeezed quite a bit but it seems much smoother now and after shooting like 20 in my backyard it's been rocking fine.


Happy to see someone said 450 psi above too. I could've sworn you couldn't go above like 220 on them. Good to know.


Someone linked me to a guy who just made some nice internals for his on FB. He had his dimensions listed as well. If I remember I'll try to find them and post them.

Ok, maybe a really dumb question, but...

How do you adjust velocity?

[RuleOfSines]

1/4” Allen right up its backside. Clockwise to increase.

How the hell did I miss this thread I’m up to 3 one is bricked 2 work flawlessly.
I have 2 more coming from Canada eventually as well

the bricked one I need to redesign the hammer and spring or work out a different way to hit the piston thinking crossbow for it.

[Killerito]

So I did a thing today. Have 1 more fully functioning one
and one that’s functional internally but not mechanically.

That stock cover looks sweet.

Well, I’m finally back in the working Thumper group! After sitting in a box for years not functioning, number 338 is back and ready for play!
