what gears for m140 spring

[old_and_slow]

I have used the search and it hasn't come up with the answers for me.....

My question is - What gears do i need to fit to be able to safely use a M140 spring in a locked to semi auto ICS V2 gearbox?

Are 32:1 suitable?

Which manufacturer is rated as being reliable?

i am aware that there are other issues with high power springs in V2 gearboxes before anyone goes off topic on that issue

Cheers

Re: what gears for m140 spring

just saying but m140 is a tad hot dont you think?
Erm shs high torque girls should do mate combowed with an shs high torque motor

Agreed, however I am building a DMR and use Battle Lakes which allows 450fps semi auto aegs with a 25m engagement.

Once the spring settles I am hoping for somewhere between 400 and 450.

Up to you really, 32:1, 300% would make things quite easy on the motor.

If you wanted to you could run them on 200% torque gears or even standard ratio, but you would need something like the SHS cnc gears and an Ultra torque motor, a big battery and something to stop the front of the gear box from leaving the party. You would need to think about half tooth pistons too. Gear set depending of course.

I didn't think standard ratio gears would support such a strong spring?

Re: what gears for m140 spring

best thing to do if not already.
polish your upper gearbox (scratch remover) polish till bleeding point!
swiss cheese your piston.
ensure 100% no airleak - O ring nozzle, e.t.c
super smooth cylinder.
"correctly" relube the piston, slide and cylinder. i use teflon spray on the tracks. madbull 6.01 stock length. <-- optional

do this before upping your spring strength and buying new gears.

Yep, done this, thats why i'm onto the spring and gears now.

Re: what gears for m140 spring

what is your current fps?
internals?
barrel lenght/size?
spring?

wich ics do you have?

Re: what gears for m140 spring

They will but it's a little hard on components compared to torque sets for obvious reasons.

I have found those ICS M4's to give high fps genearally anyway. Up to 380+ with an M100.

Something I hadn't seen befor was 400 in a G and P with no bearings and an M100.

After all, you've seen what can happen to a V2 gearbox front, even at stock levels

Re: what gears for m140 spring

Thanks Midas, you have given me all the answers I need.

Anikid - the question regarding my current fps, internals, barrel length size and spring are all irrelevant to my original question.

Re: what gears for m140 spring

they are quite relivent as how much more fps you need to gain, certain parts may not be the best (1/5 cylinder). having a short length barrel (super stubby length).
a m140 spring may = 500+
a m160 spring may = 300fps
the more we know on what you are running internaly the better we can help, ok =) (for all we know is that you are running on plastic bushings or 6mm bearings that will fail at higher fps thats all.

but if you just want an m140 go with any gears you can find as it will not matter for long.

Explain?

Re: what gears for m140 spring

Im running a m120 spring and madbull 6.03 barrel and getting 424 fps, Hits out to between 70 and 80M

All on standard g&p gears

haha its called having a predictive phone :L .
