Mag + Freestyle

bolt

An O-ring is most likely not going to be long lived in that condition. Either machine some groves into the bolt or into the body to accept flat teflon seals. They will hold insane pressure and are far more wear resistant since the design is ment for that sort of motion. Flat seals are for lateral motion, lip seals for rotational and o-rings for sealing stationary surfaces. Hmm.. Yeah I think Ive got that right... its been a while.

o-ring where? ya lost me.

I think he is talking about on the bolt to seal the LP air that pushes the bolt back. The thing is, this design has been PROVEN in Freestyles, which simply use an o-ring around the bolt/piston to seal off the LP air.

board

as for the board design i dont know if your still using an emag, but the new xmod software has a higher rof and has a slew of new settings and modes..if that helps any..and id love to see this when its done..

[Mellow Yellow]

The board will be a Freestyle board. Probably Nox incase of problems with he dwell.

[the electrician]

no, for testing, I'm looking for a board that can power two solenoids with overlapping timing so I can study a theory I haveabout flow and the operation of this type of blow forward. right now I'm using the morlock that i originally have in my homemade electro-mag. it cannot overlap the timing on two solenoids. I prefer morlocks for everything usually, because they are more versatile the timing. in the end, I imagine any board that can control a single solenoid and has versatile timing control and a full auto feature for testing reliablilty at high ROF.

the theory that I want to test is complicated, but I'll try to explain.
normally, the supply air closes very quickly and the bolt moves forward. as the bolt moves forward, the air in the dump chamber pushing it, is expanding, losing pressure and energy. so the pressure is actually lower, that is discharge through the bolt, than what the operating pressure is. I thought that what if you controlled exactly when the supply air was shut off from the dump chamber? don't close it until right at the point the air discharges from the power tube through the bolt. roughly the same amount of air and energy, but at a little lower pressure. this lower pressure inturn let's you make the inner bolt piston a larger diameter, or lower the lpr pressure that holds the bolt back.less pressure is also less o-ring friction. I'm guesstimating that it would lower the pressure about 30 psi in the dump chamber.

also, when do you open it back up? you don't want to let the supply air into the dump chamber until the bolt is all the way back, then you want to get all the air in the as fast as possible.

so this test would call for overlapping, offset, dwell times for two solenoids to test the theory.
and another very important thing... flow into the chamber has to equal the rate of expansion in the power tube. a classic mag does not have that in it's current design. and it's not the reg that is the problem like people think. the flow is restricted in the passage between the reg and the on/off, then in the on/off itself.

as far as o-rings go, the matrix, the new shocker, the ion and the freestyle all use an o-ring for the seal with an integrated bolt/air cylinder design.

what about a e2 or e1 or zero b board can power 2 noids and i believe has over laping timing

[the electrician]

yeah I know about the e1 and e2 , but what is a zeroB board?

since it's really just for testing, I don't really want to spend too damn much, but you got me interested.

[stonersr26]

From my understanding the Zero B and E2 boards are the same except that the Zero B is made to fit in both E1 and E2 frames as they changed slightly. I'm pretty sure that is how it works.
