Yeah I sent him a PM already, if he doesn't have it there are a few Rangers for sale on here I'll start asking people for pics of the inside of the valve.

I know he has a few Rangers for sale, don't know if they are this style valve though. I know he doesn't have the parts in the "graduation sale" not listed anyway.

I'm bound and determined that if we put as much effort into making Nelsons more efficient, as people have put into making Sheridans more efficient, Nelsons will get more shots than the best Sheridans.

I know we are going way off topic here but. This is the message I got back from Dan,

IDK, the closed type was probably just a theoretical improvement that was never questioned or tested very hard.
Thinking about it a little more, it probably wasn't an issue of fragile paint, but rather people cranking the velocity up in the days before chronos were required practice. After all, this was the reason for the 'venturi' bolts that Air Power first created.

Not at all "OFF TOPIC" when you consider the context Nish. We're talking about development of the Nelson valve..., and what Michael has been able to produce so far. Which by the way I'm very appreciative about.
It's great he's willing to help.

THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...
tlane77 He's got a woody for your woods.

Well now I stand corrected! thanks for the info haveblue, oh and thanks for cutting the 1/4" hex on these "tpc" best things ever!

Jack I agree in part. All the same I would like to move our off topic stuff over here http://www.mcarterbrown.com/forums/c...eperchaun.html

Just so ASP's parts aren't drowned in our theorizing.

Have Blue, I'd love to have your input on this stuff.

The cupseal was going to be the next part of the valvetrain I was going to look at - I machined slots in a CCI cupseal a while back in an attempt to improve flow around the cup edge, and I think I sent it off to someone to test. Either that, or it may actually be in my own Phantom yet and I've forgotten about it.

I did experiment with volume reducers in the valve chamber long ago, but they wound up impeding flow rather than reducing wasted space. I've got ideas on fixing that, but like everything else, I just need time.

One thing that I'm curious about is using the old style long CCI powertubes with the open faced TPC - will the extra length (and minimally reduced volume) improve efficiency, or is the slight expansion through the TPC beneficial? Perhaps the lower reciprocating mass of the newer, shorter powertube helps improve efficiency? Could the Trracer stub 'valve stem' and hammer with integrated powertube be the ultimate in Nelson valvetrains?

I'm going to quote that and post it in the thread I jsut started but I'll answer it here to. Double check with him but I believe Splattttttt found that the longer power tubes provide better efficiency. I've heard though that Trraccers were very efficient.

The devolumizers that RTR developed work really well. at one point I compaired mty Phantom to my Gargoyle with the exact same setups the only difference being the valve insert.

I think simply cutting the brass cup down so that the lip around the outside was level with the seal would be a cheap minor improvement but not the end solution

the new trracers do not use that stupid old snub nose power tube. they use a full length power tube with HUGE ports. i love the new power tubes and have several on order for some testing.

there is still some improvement to be made to the nelson valvetrain but i think we are nearing the max total shot count available in one 12ie. i theorize its around 60ish. (velocity will also play a big role)
