THE BEST SHIMMING I´VE SEEN, not like Negative Airsoft who just shits in your face this guy actually teaches you...

Thank you for your kind words :) Let me know if there's anything you'd like to see in future videos and I'll do my best to record something useful.

Finally someone shows how to properly shim bevel to pinion, so they mesh well

Good guide. Also noticed the PB Swiss. Nice quality tools.

I was looking for v3 gearbox pinion/bevel shimming but that helped a ton, thanks! I pretty much understand that I need to balance the height of the bevel for v3 gearboxes

That was extremely consistent and very helpful thank you for your clear and understandable video.

Thank you for your clear and instructive video.

Awesome stuff , used this guide to shim my gel blaster (same as AS , different ammo) , worked flawlessly

Thank you! this was clear and precise af shimming. THank you!!!!!!!!!!

Keep the videos coming 👍👍

Can u show how you polish the rail the piston slides on

Good method there Sam, I use the same one essentially. This process is a little bit less precise with an MP5 as you cannot measure the play on the bevel gear with the motor grip in place, but you can still do it with a little bit of trial and error and looking down through the top of the shell in my experience.

Aye, modifications to the method are necessary for RIFs with a covered lower bearing like the MP5 and Scorpion Evo. I have spare lowers with holes drilled through them so I can set the height using the customer’s base plate. Otherwise you do have to ‘brute force’ the shimming by getting it roughly correct and adjusting it incrementally.

hey Sam! amazing content as always! thanks for sharing! Giulio

What do you do with in gearbox Mosfet units using this method. I’m wondering if you ever need to raise the sector more to clear the sensors?

@KingdomofAirsoftUK

That's certainly a consideration. I've yet to encounter a setup where the sector is necessarily shimmed so low that it would interfere with the lower PCB of a control unit and cannot be raised. In the rare case that might happen (we're talking 0.01% of cases here) you could use a TM NGRS style bevel gear where the ARL steps raise straight up from the lower teeth. That would allow the spur to be shimmed at any height and so the sector too :)

@@KingdomofAirsoftUK thanks Sam.

I always try to shim the spur as low as possible without making contact with the shell while providing enough contact with the bevel because the sector will be to high in 80% of cases. By that I mean it will either interfere with the shell or it will have to big of an offset with the piston rack.

That is the goal for every gear in theory, maximum tooth contact with no binding and perfect position inside the gearbox. We all know this is not possible given the tolerances Airsoft parts are made to so this is the method I developed to produce the best results for any given set of parts. The bevel/pinion interaction is non-negotiable so everything else must stem from that. If the bevel sits too high for an acceptable mesh throughout the rest of the gears then the only option is to change components, either a thicker bevel or a smaller pinion.

Could you make a video on how to polish piston slide area

Do you do this when you get a new gun.. or just when issues start to present themselves? I would guess factory tolerances would not be this detailed / precise. Any grease in there when you are done shimming? Great video! thanks

I generally do this on every gun I use and certainly every gun I upgrade or work on. It’s a great way to improve efficiency and stave off any potential issues before they can cause damage. Everything gets a thin layer of grease once the shimming is finished :)

How much change will come from adding a light grease to the box regards to that shimming job? Enough to impact the tolerances?

Not enough to mess with the tolerances :) I use Superlube PTFE grease (grey tube) and it works perfectly.

@@KingdomofAirsoftUK hi sam , have you seen the new superlube dropper pens? Thinner than the original but awesome stuff and have several uses ie tappet plate rails etc

I love the idea for the filler gauge! My problem I have all the time is when I rotate the bevel gear to test the clearance there are parts that make the shimming seem loose and if I rotate the bevel is gets bound. What should I do at this point? I initially see a lot up and down movement, add .1mm. now it binds and rotating the gear loosens it up again.

That sounds like something isn’t sitting straight. I’d suggest either the bushings/bearings aren’t correctly aligned in the shell, one of the gear exiles is bent or there’s dirt/damage on the teeth. If you’re testing one gear at a time, that would suggest one of the first two issues.

@@KingdomofAirsoftUK this is my problem with every bevel gear and pinion I have tried ever. SHS, seigtech, crappy Chinese pinions, you name it. When I'm testing this it's only using the bevel to pinion gear. I has only seen one other KZreadr rotate the bevel gear when testing the side to side knocking with the bevel to pinion and notice that the gear on one turn can be super loose and the next be really tight. I also tried out your method with the filler Guage and it showed that I had about .38mm of open play so when I put .2mm it completely bound the pinion. I am by no means saying your method is wrong because it's the best method, but something is seriously up with every F'N gearbox I touch!

Did you polish the piston guides? If so, what does that help with?

@KingdomofAirsoftUK

I do indeed. It reduces friction on the piston and removes any casting defects or burrs that can wear parts prematurely. It also helps keep the grease clean for longer :)

So this method would work for a TM SCAR H as well?

@KingdomofAirsoftUK

Yup, it'll work on basically every airsoft gun out there. I use this method on every gun, including the TM SCAR-H :)

The process is identical. You still want a maximum of 0.1mm play but now some of that movement will be from the (tiny) amount of play inherent in the bearings.
