Hey all, I'm building the SUP and I've gotten to the rails, but just cracked the first piece I tried to bend into shape. I'm using 4 pieces not 8 on each side. Is it possible to get the larger pieces to bend that much? I soaked them for a day and used a wet towel and iron to steam them and still cracked it towards the nose. I'm using cedar.
Should I re-rip some smaller lumber so that I'm using 8 pieces for each rail?

Greetings kmaines! I haven't built an SUP but if the plans call for 8 strips and you are using 4 then it may be an uphill battle! I seem to remember that the SUP strips were to be triangular in section with 1" on the right angle sides...if you are getting bigger than that I would reconsider the size. Hopefully you've got some nice straight grained cedar without any knots? One possibility is to keep the larger strips and steam them 1 hour for each 1" in thickness at 220 degreess and them get them quickly to the board, bend them and clamp-em in! I'm assuming that you are starting the bend at the middle of the board and then working to the ends??? I know that for my 9-1 that sometimes I would soak the wood over the week and then install on the weekend. Even then those pesky little knots would bring on a crack. If it wasn't too bad I glued it, clamped it and called it a day Good luck and let us know how it went!

I also tried the large size and had no luck. I even broke about ten of the smaller size. I ended up soaking mine for 3 or 4 days. No steaming and very close clamping, towards nose and tail. The more clamps I had the better results I had. I ended up with 20 bar clamps and I still wish I had more. It was frustrating but I finally got all mine finished and I also just finished planing them. Lol, It took me 2 months to finish the rails.

Thanks so much for the feedback guys. The plans show 2 options for the rails: 4 or 8. I think 8 is the way to go. I'm going to rip some of the smaller size and see if they bend more easily.
Thanks!

I have done both. The size of the 4 are too big. I soaked and steamed them and still broke alot and didn't get them to squeeze together tight. I had to do a lot of after the fact repairs. I steamed the smaller ones and it worked fairly well. I had to make sure the grain was very straight and they bent right into place.

Thanks dsnow,
I'll try the smaller rails and see how it goes.

In the 11' sup plans they call for 4 1 1/2 strips, my problem is that I can't find 1 1/2 cedar anywhere! What is the thickness of the 8 piece method?

If memory serves me well the triangles were cut on 1" square strips. Remember to allow for the width of the cutting blade on the 45ยบ angle as this will distort the real size of the triangle. I've done a basic diagram to elaborate! I soaked them overnight, took them out wet and glued them wet with Gorilla glue and in general it went quite smoothly. Your ribs and spar are looking great!

Hi 159, in terms of deck it kinda depends on wether your set up for weights or clamping is good and also how well you cutting has gone. In my case, I stuck the bottom together and then glued the spar and ribs onto that with no real problem....basically I could see what I was doing and see and make sure the ribs were making contact with the bottom - used a strip of pine across the top of the robs and one underneath the bottom and clamped. However for the deck I preferred going one by one because...my cuts on the strips were not brilliant (there were some which had been ripped to 5.5mm, some to 4.5mm and also my edges weren't super clean etc.) so I wasn't convinced I was going to get a good contact between the ribs and the deck plus I wouldn't be able to see it. So, to be able to sleep at night I decided one at a time gave me more control and allowed for my "inaccuracies". Furthermore it allowed me to fill the inside with foam (before glueing the last couple of strips) which I wanted to do also to prevent a mistake of leaving the air valve open at some point. I glued one in the morning, one when i got back from work and sometimes a third before going to bed, so it wasnt that slow Like I said, if your cutting is pretty good and you've got a good clamping system then it is a lot quicker all in one go but if like me its not quite there, one by one is a solid option and is pretty easy to control. Looking forward to seeing your next step!

Thanks . That's exactly what I was thinking but I figured I'd ask someone who has experience. I have all my lumber cut for the bottom deck so when I get home from work I'll glue it all together. You've been a great help thanks a lot man.

My plans call for using a piece of cedar 1 1/2 inch thick for the 8 rail triangles. (4 per side) Of course mine is 1 7/16.... but I see comments about using 1" thick rail material....and as many as 8 triangle pieces per side??? I can still return my 1 1/2. Any thoughts before I start cutting?

I would use the 8 pcs of 1" triangle , a lot easier to bend , make sure you presoak them for a least a week

I'm I the midst of of this rail failure process. Does the bigger 4 rail system work? I've broken three pieces that I soaked for 28 hours in hot water. I really wanted to get this phase of the construction over but now it seems it needs a redesign to the 8 piece rail system. Grrrrrrrrr.

Apparently the STEAM is the key not necessarily just the water. Since I have most all the parts...plus time to do it. I'm going to try this. www.youtube.com/watch?v=50uXPPt8-VI
