How can I build a retractable medical oxygen hose reel?

Hi Rich,

Is this for a portable system or for a more restrictive home system?

From what I have been reading it does not look that complicated, but by far they sources are say it is better to buy 1 from a reputable company. This reference is by an inventor who, if you contacted her, she might be able to offer you suggestions on the "how to's", the name and phone number is in the link. Safety and flexibility are concerns that most people have to lead a more normal life when they are dependent on medical oxygen. Best to you. Hope this helps.
