So I decided I would have some fun and build my own gun instead of getting an assembled one. (also helps my wallet :shot I'm shopping around and I'm trying to decide weather I want to Buy an assembled gearbox or buy everything and assemble it personally. (I don't have a problem working on gearbox's just a few experiences that nearly ruined me DARN YOU A-R LATCH!) I've mainly been looking on evike for what I might get. I was able to find some gearbox's that looked good for around $80, while building one will be a bit more pricey because I'll get picky.
Thanks!

Have you explored airsoftmechanics.com & mechbox.com? There are a lot of little tips and tricks in those websites to help save a lot of headaches.

Which version are you leaning toward if you are going to build your own? Or do you have a body you're planning to put it in?

Also, if youre going to research parts look into who ACTUALLY builds the parts. i.e. I got a set of Bravo high torque heliquel (sp?) gears for cheap (at the time). It turns out that looking into Bravo, their parent company makes car parts in the same factory, so they have been rock solid gears, and at 1/2 the price of Systema etc.


Also, learning what parts work in other hobbies can save A LOT of money. i.e. learning to pull your own pinion gears and learning to mod eletric motors opens a whole world of other motor options that can be cheaper and/or a lot more powerful than the "airsoft" motors.

Thanks for the info!
I forgot to mention some of those details.
I am going to use an M16 body that I got. (its coming in the mail, I'm not sure the brand but I don't think that should matter?) so I would be needing a version 2.

So here is my initial build, I went to the evike website and just started grabbing stuff with good airseals and high torque. In total I'm looking at around.. $225 :nuts:

This is by no means final. Please give me suggestions or alternatives.

I wouldn't buy a brand new gearbox unless the one in your gun is plastic. Also there is NO such thing as too much torque. What motor would you be using?

Also a tip for the ARL is to turn the bevel gear into the ARL so it stays in place. (and put some grease on it that helps it stick in place) Get SHS gears. Angels custom is not too good. SHS gears are a dream.

Also that is a 7mm gearbox and you want 8mm bushings?

 

[rcon112]

I'm getting a body without a gearbox. The ar-latch was on an echo 1 scar, regardless of what I did it would not stay still... Even tried what you just mentioned.
The motor is a JG high torque.. came with the gun so I'll prolly just hang on to it.
Thanks for the 7mm ketch!

The cut off lever is designed for matrix's QD gearbox and doesn't work with standard v2 gearbox designs afaik.


I think with little effort you could get better parts then all matrix brand. Does it all have to come from one place. As well as save yourself some money.

If you are using a JG blue don't go with torque gears.

 

[rcon112]

I ended up just getting a G&P reinforced gearbox. From what I've heard its good, but I'll just throw in some parts when I get the money......

 

[goldentrigun]

I would correct your AOE, shim, polish the brass cylinder, and teflon tape the cylinder head.

 

[rcon112]

Yeah I no doubt will be applying those mods, I recently was repairing a few gearboxes for some friends and I couldn't get the AOE on their guns, because the tappet plate was preventing the gear from rotating to correct AOE?(i.e. first gear touching first tooth).

 

[Star_folder]

You should try correcting the AoE without the tappet plate installed, as it really has no effect on the AoE.

 

[rcon112]

I'm sorry, does the nub on the sector gear sits under the tappet plate? I think I tried it but the plate wasn't sitting flush. Oh well I'll give it a go when I get my gearbox in! Thanks again guys!
