calling ego owners help required

[robof9]

i think john is remarking on mechanical dwell increasing, which yes it will do, but not alot, but that is why you can lower your pressures, valve does seal after each shot and doesnt leak down the barrel

well im giving it a go on saturday/sunday if not good then i will tell you if good then wayhey.

the 3 springs that i have are mixed in weight 1 very light, 1 light medium and one medium all compared to ego spring, i have some reduced in length and other which are same length.

as for efficiency, only time will tell

as for price theyll be low priced not sure, depends on interest

skeet thanks for the +ve comments, will talk with u later.

Yes robof9 I am thinking the increase is due to mechanical dwell. Which is the same as just upping the dwell setting on your board a bit, but with the disadvantage that the bolt may have started to retract as the valve is still open.

I dont think the spring has an effect at any other time in the firing cycle except when the valve is open and needs to close.

A interesting experiment would be to measure the force of your springs (at the compression they would be inside the gun) and calculate the force holding the valve closed. (area of valve * firing pressure) to see what ratios these have.

Also remember to do the bingo ball test, where you stick two balls in the breach, fire once and see how high the ball above jumps (if at all)




The holy grail of the bang valve marker is to reduce the energy required to open the valve properly.


I have seen a million different approaches, all but a very few have succeeded.

Please dont let my pessemism put you off though. As long as you take a scientific approach you will get the right answers...

MQ Valve in teh ego..sorted

Whats the problem with lowering LP and upping the dwell?

The higher dwell isnt any harder on paint bud, just slightly more inefficient if anything.

That is what I would do.

Higher dwell has no effect on paint, it only makes the gun a little louder.

Efficiency would still be head and shoulders above many other guns.




But yeah an MQ or newton in an Ego would be sweet.
The only thing I dont like about the ego is the kick (and bits coming unscrewed etc as a result).

 

[robof9]

there is nothing wrong with upping the dwell apart from solenoid wear, minimal probably, the upping of the lpr could cause more impact damage, as the bolt will be travelling faster on impact, (this of course relates to lightened bolt, pin users) evolve work on low lpr settings to reduce chops in the newton.

the reason for the project is for the fact that every one wants to remove all kick from the ego, hence ndz bolt, delrin pin, the trouble is the moving mass is very small, and alot of people are having probs getting desired velocity, this is what im adressing

but the testing will require more than my set of results

if i had come on and said great new product that reduces kick, replacement valve spring, most people would think , why not, it dont cost much, easy to change and i can always go back to stock.

i want to test 1st b4 i sell, that is my way, as itterated b4 it may not work, but this may eter others from carring out the tests in the future

i will bingo ball tommorrow with all springs, 2 diff bolts

also skeet, whack a mq in it(if it fit) and a e2 board viola closed bolt ego(moving lpr hosing of coarse), lol

Mate solenoid wear? come on the solenoid will last forever so long as the gun is maintained, having the piston stay in the open pisition milliseconds longer will surely have no effect...

The only way to really lose kick is to get rid of the rammer, its the heaviest part of the reciprocating mass, you could machine it down but its pretty small anyway, and if you make it too light you may actually end up having to raise the LPR to get the velocity high enough, its a bit of a balancing act when you have multiple stored energy components acting against one-another.

I think as above an MQ is the only feasable mod that would make any real difference, i would bother messing with the spring bud, cos at the end of the day it is the inertia caused by the ram/bolt operating (quickly accelerating/decelerating) that gives 'kick'.

Just my opinion tho.

So...how does the ego fair...kick wise...with no bolt..and just the rammer cycling?
Much different?

i do not doubt any opinions expressed, but trials will be made using the springs as i have them now, if the results arnt favourable, then fair enough, if there is no improvement fair enough, but it is a bit of an unknown at the moment.

i could boar you all with the calculations, but to be honest im gonna try it and see, dry firing this afternoon didnt really see any difference, will do the tests mentioned before, any others i should do?

all comments are welcome, good/bad no problem.

as i said before this is an experiment and if there is no gain then i wont sell it, if there is a gain then i will.

at least it will finally be answered

be interesting to what nicky t thinks about this mod
