Lack of parts in my garage forced me to make a very simple ghetto setup…
Parts required:
* Tubing that fits snugly over a presta valve.
* A nail.
* Air from a donor bike tyre.
Hammer the nail thru one side of the tube about 1.5 to 2cm from one end. This will push the presta valve on the donor when you push the tubing onto the valve. That’s all the DIY there is 🙂
I used another donor bike as the air chamber. I got enough air with a 26″x2.1 at 65psi but it took a few goes as I wasn’t using washing up liquid. It’s not quite quick enough to do instant pop inflation. A plastic bottle with higher pressure as per the original suggested ghetto setup will be superior, but you could still make it with just one valve in the lid.
How to use:
Take the tube end without the nail and push it over presta valve of the wheel to be inflated.
Take the other tube end *with* the nail and push onto the value of the donor bike wheel. The nail should press the end of the valve and release the air.
