And so it begins...

Took this thing apart quite a while ago and got stalled out. Everyone stand by for dumb questions.

Sweet!!! Looks like a good start!

You wouldn't happen to have a list of O-rings would you? Probably not, but worth asking haha

Edit: Yes, it looks to be all there and in pretty damn good shape. I need some LP hose, a braided line, some fittings. My plan is to return this one to a functional stock - no modifications unless required to get it going. May freak bore the barrel. I want to take this thing in all its turn of the century goodness.

This looks familiar .

There are a few mods that are generally considered to be necessary, and I would suggest gutting at least the HPR assembly and run an aftermarket reg.

Is the factory HPR that bad? What is the normal pressure range for one of these things? Is gutting the regulator a.reversible process (i.e. the internals could be reinstalled should their be need/want)?

I am trying to keep this thing as factory as possible, even if peak performance cannot be achieved. I appreciate any help/suggestions. I had two of these way back. One was bone stock and the other had been modded when i purchased it. So I am familiar with them to a point but never did much to this platform personally.

In short, yes, it's that bad.

Depending on internal mods they generally run at 400-500psi... gutting the reg is reversible, depending on how it's done.

It's not really a "peak performance" thing, I've heard of and seen 30-40 fps swings with a stock HPR setup. It makes them much nicer to use. You can leave the LPR alone assuming the piston and reg seat are still ok, they're usually adequate unless you're trying to push the cyclic speed up.

The other crucial thing is the anti-friction mods to the hammer and carrier assemblies.

Understood. That is quite a +/-. Do you have a recommended method for a non-destructive gutting?

What does the anti-friction model entail?

Also, there wouldn't happen to be a list of orings somewhere would there?

If you want to retain the factory appearance, remove everything from the HPR block, plug the vent hole in the reg spring cap, and loctite the cap and adjuster onto the reg block. You'll still be able to revert back if you want later with a bit of heat.

The anti friction mods require a bit of fab work. Check the RM info sticky for a picture of what needs to be done, I'll work on a more detailed post as to what is required.

I still need to figure out oring sizes... I've never paid attention to size, I always just installed whatever fit and sealed in the past.

Not having a RM anymore makes it harder to create informative writeups.

Looking forward to that info, I still haven't done the Mad Marty mods for Maggie.

Jordan I can do the mods with your guidance, and take pictures, if that helps.

Sounds great!

I've got an extra carrier I can mod but no hammer, so I'll do what I can here and walk you through the rest.

Alright, the body is loaded.

Questions for Jordan :

Can you recommend a source for LP hosing?
Can you recommend a source for the LP hose fitting (barbs)?

Thanks to Dragunov151 for kicking me into motion lol

It's the same stuff Cockers use, so you're covered there as far as easy accessibility goes. maggot has some great stuff that's available in multiple colors.

All the pneumatics take 10-32 thread barbs. I prefer to swap the old plastic stuff for metal... AirSoldier Products has some nice 90° elbows I've used in the past... I can grab a link to them if you need one.

I just went and looked at my Rainmaker, and breathed a sigh of relief I don’t need to take it apart :P
