The thing I love about cycling the most? Making your own solutions to occasional problems. The ghetto tubeless bomb.

Compressor is in storage but tubeless tyres still need to be mounted.

 

1 2.25l coke bottle, 1 removable core valve, 1 normal valve, 1m 6mm hose, 1 hose clamp, 1 6mm drill bit and a bit of silicon. Pinch hose. Connect hose to wheel. Pump to 100 psi. Unpinch hose. Listen to the pop as tubeless tyre sets.

Nice - been wanting to try that. How'd you get a good seal between the bottle top and the two valves? Looks like you added some washers, did you seal with silicone too?

Added washers only to get the thread to the right height and to level the valves. I did use silicone on the valve stem before I pulled them through the holes and then applied a fair bit more into the cap making sure the valve holes stayed open and on the cap thread.

 

I use the jo blo mountain to fill which only goes to 70 psi which is adequate for my road tyres. The high pressure pump is lower volume but gets the bottle to 110 psi after a few thousand pumps.

 

A bigger top might work better for sealing as a bigger flatter surface. Something like an orange juice bottle. But that might require some duct tape to strengthen the plastic.

PLEASE PLEASE DO not do that 

 

Even at 18 psi if that thing blows the shards CAN kill you

Please see this thread, I made one out of a fire extinguisher that CAN SAFELY go up to 205 psi

 

This is enough for four 2.4 29' tyres.

 

I'll tell exactly how to build it ,but I really don't want to hear about someone that got killed by pumping up a coke bottle.
