Info Request - Line SI Bushmaster

[BlackHalo]

Hey guys,

Just wanted to see if anyone knew anything about this gun. A friend of mine gave me a broken one and I wanted to get it to running condition.

The power tube / cupseal is broken, if anyone knows where I can get replacements. It's also missing the little spring that's supposed to be behind the cupseal.

Any other info on this marker would be greatly appreciated! I don't know much about nelson style markers.

Thanks!

They are Nelson-based markers, so if you just want6 to get it working again, you could swap in parts from a Trracer/Maverick. Original Line SI parts would be mighty hard to come by.

I think my local pro-shop has some of the old-style Nelson power-tubes. They were from Ram-68's, but are closer than anything else you are likely to find.

www.iisports.com bought up all of Ross Alexanders parts when he closed up shop. They are based in LA I believe.

The mainspring and cup seal spring are Nelson springs. Any Nelson based springs will work. There are a lot of replacement spring sets.

I want it =(

I need a pump you meanie...

I Am Not!

I'm not a meanie! I just happened to get here first! And I"m a collector. I'm ashamed to admit that an SI Bushmaster is one of the few models I DON'T have in my collection and this is an opportunity to change that. So you're right TK, NO way is this slipping past the ol' Jew. Nuh-uh. Phantom fixed-barrel, KP3, P-68 Piranha, Splatmaster, PGP move over, Josh needs a Bushmaster (that isn't electronic).

I believe that Palmers Pursuit Shop has a good supply of Neslon based parts. I bought a bunch of stuff for some of my old pumps about a year ago. Call them and check.

looks like you got all the info you need, so I will just show off....

They have some parts, power tubes etc. You can also check at the PHOG , Dont quote me on it but I believe you can swap phantom internals with changing out the sear. The guys at PHOG seem to know where to dig up every spare part for a pump.

I have some original NOS parts for that gun.

People still want these things? Out in the garage, I have a stainless version with collapsable stock somewhere......

[BlackHalo]

Wow

Thanks for all the info guys.

Josh2Xtremes - Sorry, I'm not really looking to sell it right now. If something changes I'll let you know .

G3pb - E-mailing you now! wooo

Krusty - I'll go check out airsoldier and PHOG

Angelpena - Nice, the one I have has the lever changer and a back bottle / bottomline kit as well. There's also 2 small thumbscrews on the top rear at around the 10 and 2 o'clock position holding the valve(?) section in. The bolt seems to be metal in the back and delrin in the front.

Mindjob - I posted on POG as well, I'll go see if PPS has anything.

Looks like I have the replacements covered.
Can anyone tell me how the powertube size / hammer spring / valve springs relate to velocity?

Thanks again!

[G3PB]

Springs...the lighter the valve spring, the longer the "valve" will dwell in relation to input pressure, basically, same can be siad for the main spring. For consistency, shot to shot, best to use the heaviest valve spring and the lighest mainspring that will still provide needed velocity. Also, depending on bolt, most will be adjustable...see if the part of the bolt that slides into the hammer is screwed in and has an allen socket through the bolt face.
The "delrin" front bolts should be adjustable as it's an aftermarket, if I remember correctly....been a long time.

Power tubes, the number relates to the air passage holes, they'll be 4's and 6's...the 6 provides more flow. I think tubes was Lapco's first product since the factory ones always tended to break at the passage holes...one always kept spares along with a ton of springs.
Velocity was controlled by these fews things and a part of being a good paintball player back then was knowing which combination of parts to use on any given day since Co2 is so temperature sensitive. Best thing to happen was when regs came into use, of course by then, most of us were rarely touching pump guns anymore.

The only one I've kept in real cherry shape is a Grey Ghost, set up California style back before the common use of a pin valve tank.

how many of you guys can still remember those?
