How to modify a LEGO pneumatic switch for optimal air flow by Techbricks.nl

[funes79]

I tried this but the switch leaks. So I do not recommend to open the switch, just to drill bigger holes which will help the airflow. I dont know how they assemble the switch in Lego, but they have to create an extreme force to push the lever when they glue it.

quick question, will this modification work with the other version of switch? cause my switches leaked after modification.  PS: i know your website lol

Thanks for the video, my engine wont run without this.

[SMGJohn]

I cut my finger off. Is this suppose to happen or maybe I was just to careless??

[WorldofMindstorms]

If you modified your switch and cylinders but also needed a T split in between, would you need to modify that as well to keep the speed?

[ruben4884]

I build a motor to and I want 4 modified switches but I can't open it. can i maybe buy it ? I have 3 switches but i don't now if it the right one.

i used this to get my pneumatic locomotive working and now it finally does! Thx a lot!

A small tip: Nail clippers are surprisingly effective on legos.

Dude i swear about 15 times in the video, the way you were using that hobby knife, I thought you were going to stab yourself!

[jakebartelmay]

dude you should break out the dremmel tool and save the fingers

[WpA09]

why not putting the glue on after you put the back plate back in place?

Skip to 3:49 for when he opens the switch.END.

yes sorry i whas a litle angry because my switch whas destroyt i have deletet my comment

[techbricks]

@1100lolbroek: No thanks for calling me a liar ;-) It is indeed very difficult to modify a air switch. It can easy result in a valve that is leaking air or one that doesn't move smoothly. As I explain on my techbricks dot nl web site it cost me a couple of valves myself before I had successfully modified them.

[Symnogtx]

I know that modified switches leak a bit, but si it possible to modify them without leaking?

[techbricks]

@Symnogtx : check my techbricks dot nl web site for more info.

[Symnogtx]

Is it possible to modify the switches without that they leak, even at 5 bars?

[SpeedyGonZohan]

Now on your website you say you use a glue that you mix up yourself (for re-sealing teh back plate on) An at 8:31 you say use an Epoxy. Which one do I use?

[techbricks]

@SpeedyGonZohan : I use epoxy glue. Before glueing you must mix the two components of the glue.

[SpeedyGonZohan]

Now on your website you say you use a glue you mix up (for re-sealing the back plate) and at 8:31 you say use Epoxy glue. Which one should I use?

[ofcadoneghe]

Do you cut also the pin in order to remove the back plane?

[techbricks]

@ofcadoneghe : Sure you can, but I alway try not to break ik at all. But that doesn't happen very offen.....

[omgsean1]

@techbricks sometime happen to some people did break them during modify switch

[japsujipsu]

show what is the difference

[techbricks]

@japsujipsu The difference between a LPE with modified switches or without them is this: He runs very fast or he runs poorly or not at all....

THANK YOU!! just what i wanted :D
