So you want to build a Mechanical Ion?

[Trbo323]

I'm assuming someone in here has experience with the SMAV-3. I'm thinking about another project and had a few questions about how it functions

I'm assuming the input is on the small end there, what I would need is output to let's say output A until it is pressed, then output to B . When released I need the venting of B

Venting of A may be a null factor whether it vents or not but I would like to know

Thanks all. Can, qev and bolt bought. I will rebuild the reg soon

The first concerns the epiphany's fire can, which has too high a working pressure to operate mechanically. I have the 3 inserts with it and you can even use it without an insert. Wouldn't that be a solution to increase the air volume and lower the pressure?

No. Even with all the inserts removed, the red epiphany firing can does not have a enough volume to reach velocity at mech ion operating pressures.

The second question, in connection with the first concerns the fire can NDZ. What does it have more than that of an original ion?

Volume. The NDZ Ion can has more volume then the stock Ion can, so it can reach velocity at even lower pressures then you would be able to with a stock mech Ion can. I'm not sure exactly how much volume, but my mech epiphany that uses it operates about 20/25 PSI lower then the mech Ion's I've built that just use the stock Ion Can.

Finally, you talk about QEV. Is it compulsory? Should I use it in front and behind?

QEV's are strongly recommended for mech Ions. The gun will function without one, but not well. You only need 1 QEV, the "front" one. Adding a QEV to the rear wouldn't do anything.

Even without any inserts in, Epiphanies run at too high of a pressure to achieve 280fps... the weak link is the 3-56 barb on the Smav, the hose just leaks and/or pops off over 200psi.

I tried, believe me.

Short of mechanically securing the hoses, whether you use some type of clamp or an adhesive, they will come off the Smav. Even with securing the hoses, the Smav is really only rated for 150psi max, and the valve gets progressively harder to actuate as input pressure increases over that max, IME.

#1 yes the Epiphany can operates at a higher pressure than the Smav 3 valve is rated for, but I think someone here did it. Would it be beneficial in any way? Not sure. The Ion platform is a gas hog no matter what.

#2 Not sure haven't dealt with one of those, but if it is for an Ion, not an Epiphany, it should be alright

#3 See my comment right above yours. You use it on the front can fitting only. The rear of the can "vents" through the breech when you fire a shot, unlike the front chamber which has to dump externally to allow the bolt to go forward.

After giving up on my ion mechanical project for a bit and wanting to finish things in progress, I ordered a mech kit from SSC. I had first thought of buying the parts but some only come in pack of 5 and I don't want to make my own kits to sell, I have so much going on that I don't want to disperse myself even more.

So I reread the whole post from the beginning and I have 2 or 3 questions to ask.

The first concerns the epiphany's fire can, which has too high a working pressure to operate mechanically. I have the 3 inserts with it and you can even use it without an insert. Wouldn't that be a solution to increase the air volume and lower the pressure?

The second question, in connection with the first concerns the fire can NDZ. What does it have more than that of an original ion?

Finally, you talk about QEV. Is it compulsory? Should I use it in front and behind?

[JeeperCreeper]

I have one without, and 2 with it. The QEV allows for a slightly lower pressure which is better for the valve in the long run. It's also snappier as the bolt can cycle forward just a bit faster.

Hey guys comming back i have mech my gog excty from a comment before , and i added a qev last week and haven't noticed any big difference, have anybody tested the qev for the added speed or efficiency?

[ChoSanJuan]

Yes! Been meaning to mention that. Glad someone did! It's like an old skool cocker. 😁

[JeeperCreeper]

I know I kept kinking the main line in myself. This made things so much easier to position the smav into a good spot for a nice trigger pull

[Cdn_Cuda]

Thanks, that’s a great tip!

[JeeperCreeper]

I just want to add a quick tip: use pen springs over your lines where you have bends to prevent kinks

[ChoSanJuan]

ChoSanJusn,
With your guidance, I just finished meching my old Ion.
Thank you!!!

YES! Congrats! Throw up a pic in the sticky. I wanna see!

Thanks i end up getting parts from a enmey, it works but got a leaky valve , so im thinking about maybe getting the smav valve intead , has anybody tested mech ion vs enmey?
