PVD Keg Trailer
Contents
Wheels
20" Sun L20 Single-Wall Wheelchair Wheels - $64.35 ea.
36 spokes. Radial lace.
These wheels are ETRTO 451, not 406 as most 20" BMX wheels are. This created a huge problem with tires, setting me back a while. ETRTO 406 is what most 20" tires are.
Axles
Edmond Wheelchair Repair and Supply
Preferably QR, waiting on wheels to know size.
Keg
2½ GALLON NEW BALL LOCK CORNELIUS TYPE KEG - $92.90
My partictular keg is a 2.5 gallon keg by AEB. 14½" tall, and 8½" wide.
Since the trailer should be capable of carrying a 5 gallon keg at some point, the max size should be 25" tall, and 8½" wide.

Genuine Innovations Cornelius Keg CO2 Charger
CO2 Cartridges
The injector will work with commonly available threaded CO2 cartridges.
These are very expensive at bike shops, upwards of $5 each for 16 gram units.
3/8-24UNF-1A thread. Note: Schreader valves are 5/16–32 thread.
They can be got for much cheaper, the key is to ensure that the cartrige is made up of pure CO2:
