Replacement DRE Rail?

I hope you guys can help me out. I'm looking to grow my DRE frame just 2-3 inches by replacing the two bow to stern rails. I know they are aluminum but past that can anyone point me in the right direction as to what kind of aluminum and where I might be able to find replacements at a reasonable price? Once I have it it should be a simple matter of creating the holes for the pins and griding down the edges a little. There are not any bends and both sides are the original female receivers.

Thanks,

Matt

A stretched my frame a few seasons ago and here is what I was able to find....

The aluminum tube used on most frames is designated 6061-T6. Depending on who made the frame the they probally used
1 1/2" (1.900" o.d.) nominal or 1 1.4" nominal

Sorry, previous post was corrupted, here is a second effort.

A stretched my frame a few seasons ago and here is what I was able to find then....

The aluminum tube used on most frames is designated schedule 40 6061-T6. Depending on who made the frame the they used one of the following sizes. Measure carefully and be sure of what you have. (note: nothing on a 1 1/2" pipe will measure 1 1/2"!)

1 1/2" nominal (1.900", 48mm o.d.)
1 1/4" nominal (1.660", 42mm o.d.)

SpeedRail fittings are made by 'Hollaender' here is a link to their pipe sizing guide. http://www.nurail.com/2010/images/nav-on_09.png

ALS Industrial Supply, 303-355-2391 was the best price I found on fittings in the Denver metro area. You will need to go on the Hollaender web site and pick out the fittings so you can order them by item number.

DRE in Wheatridge will sell tubes of either diameter cut to length... http://www.downriverequip.com/asp/product.asp?product=807

I also found a metal distributor in Brighton that was willing to sell cut lengths to the public. They normaly deal with professionals so do your homework, they have little time for 'noobs'.
ALRECO, 11299 Brighton Blvd, 303-287-7210

Note: the tubes sold by DRE are anodized, the ones from ALRECO are not. The non-anodized tubes will rub off on stuff leaving a dark grey mark that can be difficult to remove from your raft.

If you only need to stretch things a few inches you might consider a 'break down kit" type of splice...
http://www.nrsweb.com/shop/product.asp?pfid=1200+RBD&pdeptid=1178
This is a solid bar that fits inside the tube and is pinned with through bolts. You could get (or fabricate) an oversized one that would easily add a few inches.

I would just get what you need from DRE, doing it once, doing it right is always the best way. Or try NRS they sell the pipe by the foot. The anodizing is key to keepin the black crap off your boat! I always go with, you get what you pay for.

It may be that you can get a hoop with swaged (sp?) ends that will go into the ends of your existing tubes. Might grow a little more than you want, but maybe you could cut some off of yours to compensate?

Kengore, thanks for the info. I called DRE a while back and I remember them quoting me something like $200-$300, which seemed crazy. Maybe there was machining figured into that... Anyway, I only need 2 5 foot lengths which by your link should only be about $60.

Badazws6 - I'm not sure how things might have gotten cofused, but the 2 x 5' sections of 1.5 inch anodized alum. pipe would be $67.90. ($6.79 per foot)

I hope that clears some things up for you.

- Matt

I've been talking to DRE and I'm not sure where the mix up was but the cost for new rails is a lot lower then I thought. DRE as always is being very helpful.
