Home made Raft Frames

I see there is a lot of experience on this board with home made raft frames. I've read most of the threads and I think I get the gist, but I had a couple of questions:

I'd like to put together a frame using aluminum pipe. Is there a better source than NRS?

Chip recommends a dowel inside the tube where a compression fitting will be used. What diameter? Are you putting a dowel in the whole length of the side rail? Just part?

I'm skeptical about fittings that use set screws. But the NRS low pros are too heavy. Does anyone bolt instead of set screw the speed rail type fittings?
these
Oar towers: NRS style, or DRE style?

I'd like to make a breakdown frame. I'd keep the fittings in place on the side rails, then use hoop clips to pin the cross pieces into place. Anyone done this? Any reasons it's a bad idea?

I'm inclined to use low pros on the bow, stern, and footbar rails, and speed rail type fittings for rails that support dryboxes or coolers etc. Thoughts?

Thanks all!

Mostly, I use a piece of dowel in the ends of the pipe where the fitting clamps down. I have driven pieces in (with a smaller dowel) to support the tubing where the drops attach. Only place where I inserted a dowel full-length was on the crossbars that support the seat (on my new lightweight frame of 3/4" IPS tubing).

If the dowel is a tight fit, it can be difficult-to-impossible to insert a long piece.

For fit, best to take a short piece of tubing to the hardware store and match the dowel. Some sort of dowel or other support is needed for the thinwall steel tubing that I use. Schedule 40 aluminum has thicker wallsó wouldn't hurt to dowel it, but I don't know if it's absolutely necessary.

Rather than those spring-hoop clips (@$2.00 or so), I'd go with 1/4" machine screws and acorn nuts. Same strength and you don't have that bail sticking up to catch stuff.

A fitting like this might do better if you are going to bolt it. I was thinking of doing the same thing on mine!

Hello

If you check out frontierplay.com they can give you a few ideas on how to make a frame. I used metal fence post bought at hardware store. I used the connection pieces from frontierplay. The set screws have no issues at all. It cost me 300 dollars for a 4 bay frame, oarlocks, oar mounts and chair. Its weighs about 20 pounds more then a NRS frame and 500 dollars cheaper. I took my frame down the Grand Canyon and it worked perfectly. I like the DRE oar mounts better, easier to adjust. You can also break down the frame by taking it apart. Takes 5 minutes or less. Hope that helps. Cox

For me the main reason to go to the DRE oarmounts was I needed height since I sit on a cooler. NRS only come 8" high, if they are even that.

ihowwent,

What brand or o.d. size of tubes did you mount your DRE to?

Thanks!

Are you talking about the boat tubes, or the piping? Sotar boat, 20" tubes, Frame built of NRS piping.

Sorry, I was referring to pipe. I'll probably be ordering my pipe today and thinking of going with 1 5/8" OD. I have a 8" NRS stand, but a little concerned that it might be a little short once I get everything together. I just wanted to make sure my pipe size selection would be compatible with DRE in case I need a taller stand. Your NRS uses 1 5/8".

If I recall doesn't DRE use 1.90 OD? How loose was the fitting when to slide it onto your NRS rails?

You just order the oartowers "FOR NRS", and they come with the proper speed rail fitting, nice fit.
