Hi to all,
I am the proud new owner of a Rocky Mountain 16' self bailing raft and am interested in building a frame for it that is less expensive than the NRS or Down River. I have seen some other threads on the topic, but still have some concerns. First, here is what I am looking at:
My idea of a 3 bay frame
2 88 inch sidebars - ($79.20)
4 67 inch crossbars - ($124.0
4 90degree elbows - ($44.04)
4 tees - ($51.84)
2 NRS oar towers - ($74.95)
2 NRS oar locks - ($74.95)
NRS seat mount- ($52.95)
Highback tractor seat (59.99)
Total (not including tax and shipping) -$562.00
Shipping on the pipe is $30
Shipping on the elbows and tees is $17.00
Not sure about NRS shipping
So I think that for just over $600, I could have a customizable full size 3-bay frame. I do have some questions and concerns:
NRS and Downriver use two different types and diameters of aluminum. NRS uses 6061-T6 aircraft-grade aluminum with an outside diameter of 1 5/8 inches (= 1.625 inches). Downriver uses 6063 alloy schedule 40 T6 aluminum with an outside diameter of 1.9 inches.
I Think that it makes sense to choose a pipe that has an equal or very similar diameter as either NRS or Down River so that we would be able to use their oar towers and seat mounts.
The aluminum pipe that I am looking at is the 6061 schedule 40 aluminum pipe, with an outside diameter of 1.66 inches. I think that the .035 inch difference between my pipes and the NRS pipes would not affect the U-bolt style attachments on the oar towers and the seat mount. Let me know what you think.
Also, the pipes that I am looking at are NOT ANODIZED. I think that anodizing allows the metal to be a little more resistant to corrosion, but I am not sure how much of a big deal it actually is. Let me know what you think.
