The inch and a quarter schedule 40, 6061 T-6 aluminum pipe is also available online from onlinemetals.com, if you can't find it locally. They will sell you the pipe for@ $25.45 for 7 feet but then want $17 for shipping, (which I suppose will vary depending on how far you are from their nearest shipping point)..that would bring your total to $42.45 but save you the time and gas money involved in chasing it down. The other thing to know is that they will ship 5 pieces to me for $22 so that would bring the price of shipping down to less than $5 per section....so if you have several buddies who are interested in making a bar, that would be the hot set-up. There is also 2024 aircraft grade aluminum tube available, but that stuff is overkill and three times the price.
I'm so glad I found this thread ... I need one in a bad way ... I'm 5'6", 145 lbs and this would save my life ... I can sail solo knowing that I have a way to right my H16.
