Well, after building my air tanks for my pneumatic snake
, I needed a way to get them inflated faster then with the tiny lego pump. What's faster then a lego pump? A bike pump!

Step 1: Supplies

  • An old inner tube. Only valve needs to be working.
  • A tube that a lego pneumatic hose will fit snugly on.
  • Glue. I used hot glue.

Step 2: Assemble

1. Cut the innertube valve out.
2. Insert the tube into the end of the valve.
3. Glue.

Step 3: Done.

I found this to work extremely well. Filling my small air tanks took 30 pumps with my lego pump and 2 with a SMALL bike pump.
so.......do you leave the pump connected? and what about a valve for letting air out...im guessing you use the one that u buy from lego?
haha I wouldn't even dare trying this with my high pressure (~160 psi) pump. But that's a great idea... for even faster & easier refill you could look into the air canisters inflators!
My bike pump goes up to 240psi!
It wouldn't make a difference. The hoses will pop off any connectors if the psi gets over 40 or so.
Any chance you could get a psi measurement? It would be insanely easy to measure it while its setup like this. I always wondered what psi this stuff worked at when I was a kid.
It goes to about 40 psi when the hoses pop off. I usually keep it at about 35.
Just be careful not to over inflate it...
You can't really over inflate Lego pneumatics, the hoses just pop off.
