But...but...it's plastic. It'll break. It'll stand up to maybe...100 shots maximum and then something will break.

i know it will, i plan to replace broken pieces with cast aluminium at first, sear ca be easily made by steel.
And i will count bbs fired before it break, that will be interesting.
case should be ok, with only static loads

 

Yeah. That might work. Interestingly, on my well mb04, it wasn't the sears that broke, but the actual trigger. You might want to replace that as well. Also, ou can get cnc machines (relatively) cheaply, so I would use that instead of casting.

i design sear to transfer most of the load to case, sear is longer at bottom, in normal designs sear has equal length, in hope that will not brake the other 2 component. trigger pull its lighter then my m24.

 

Casting will be fine as long as you use decent cast grade material and make sure your forms are good and your pours are fluid. A great many airsoft parts are cast then CNC finished, then marketed as "CNC Machined." Fooling all of you.

Honestly if your going to invest in a CNC machine, you better be thinking from a business perspective as that is the only way to justify the price tag of a remotely decent one that will not give you problems. (You should ask me how I know, and be prepared for a long discord call of 3-4 hours minimum.)

Though for the price you can get manual machines with a decent amount of tooling for the price tag of a CNC. (and yes I do mean multiple!)

 

Had thought about this myself! Boy, would it be fun to make some custom hopup chambers! But alas, there's no way I can afford 4-5 figures in the next 10 years! It would be one sweet business idea, however!

 

i have a design for M24 if you want

 

can i have it

 

that the plan, less proprietary parts=better

 

It would be cool to make a trigger that can fit both in the tm aws and the vsr10. They are kind of similar anyway. What would be impressive is if you made one that fit in the Well Mb01 and the vsr10.

I will try to fit the one from my M24, i think is like one from mb01.

 

I think that the spring guide stopper is slightly different but otherwise they are similar.

For the printed trigger box shell, if you do want to do a casting, print it with those burnable filaments and use the 3D print as an investment for casting. Print it with as much hollow as you can, coat it with the ceramic slurry or just with plaster. Burn it out in the oven and the do the casting with it once you bed it in sand. Just oversize the print to compensate for the metal casting shrink.

 

ok after open my M24 trigger box i notice the trigger sear present some wear, its made of alu alloy and spring sear of steel. so i decide i want to make a trigger box with lightest possible pull, and easy to machine for future >
so i design trigger and spring sear form a 6x6mm steel bar and for spring stopper will be a M6 screw with minimum modification
piston sear will have a small piece of plastic glued on back for spring tension to further simplify metal working.
M24 sear its way to small to fit in this design. may be only if case is made of aluminium and the sear is turned upside down. but who want a sniper with a heavy trigger pull?

 

here some update, i use 6x6 steel bar and a 2 mm plate for trigger sear for wear resistance
now i work at a new design with plasma cutting in mind. may metal shop has a plasma, laser, water cutting machine then a cnc , at this point will be cheaper to make it out of steel then aluminium.

 

CNC??? Plasma Cutter??? My goodness, my dream airsoft shop right there. Good luck

 

here a beter stronger version. not tested yet.

 

hello, where is the stronger version. Did you upload it in thingiverse ??

 

added update with steel spring guide stopper steel piston sear and composite trigger sear.
this is the most tested version so far (about 1000 bbs)

 

Hey, I was wondering what kind of piston do you use in a VSR?
also, the springs you used look like from an AEG?

 

its a vsr piston and a vsr spring in vsr cylinder.

 

I can't be sure of what piston he is using, but I am fairly certain that he is using 9X13mm APS-2 style springs, similar to the SSG10 and Lambda FAT springs

 

@arcticd it seems that you forget to include the triggerbox cover in the thingiverse package.

 

i added the cap thx

 

it seam this plastic box is more resilient then i thought. still nothing brake, trigger is funny and springy but that all.....still amazed by it not broking with 3J spring

 

That's awesome, now that I've got a printer I may have to make one!

I imagine you used PLA for all this? I recently bought some PET-CF which would probably be great since my car gets pretty hot sometimes.

 

Good luck!
