Popular Post Bmac Posted March 28, 2020 Author Popular Post Report Share Posted March 28, 2020 Quick update on the SUP. Last post of progress was on Tues, and I haven't moved as fast as I was hoping. Partly because we've had some nice weather and work on my garden/yard/house pulled me out of the shop. But that's ok, I'm still moving forward and the amount of glueups has been tedious. After finishing the top decking I began prep for adding the lower decking and for "closing" up the board. I have a few things that need to be done internally before adding the bottom deck. First is added glue strips to the plywood framework, a real long process. Here are my strips prior to sizing, and in the end I used all these; Gluing up to the plywood framework, glue to the center and to the cross pieces; Next I need to make sure that all the chambers of the board are connected for even air pressure. Some simply holes placed in the center support; And some notches in the cross pieces. These notches allow not only air flow but also can act as drain knotches in case water gets in the board, not that I plan that to happen; And here's the board woth the ribs glued on and all ready for the deck; Couple other things to point out. Blocking for leash cup and air vent. I'll be using an combination device fitted with a goretex membrane. This membrane prevents water for coming in but allows air to escape. The hole in the block will be centered at the bottom of the larger hole I'll drill into the top of the board to insert the leash cup/vent; Next, I prepped the back and front of the board for blocking the will form the nose and tail. Here's the tail; Here's the nose; Finally, got the fin finallized, First cut out; Next mark the midline; Then shaped/feathered both edges down to that line, this is called the foil for the fin; So the next steps will be leveling the supports, alittle work on blocks for the nose, and the adding the bottom deck. Thanks for looking! 9 Quote Link to comment Share on other sites More sharing options...

Coop Posted April 1, 2020 Report Share Posted April 1, 2020 I built a surfboard years and years ago with foam and glass and obviously no concern about an air vent. Why a concern about it here? Due to the air mass inside heating up? Quote Link to comment Share on other sites More sharing options...

Why a concern about it here? Due to the air mass inside heating up? Yes Coop, say you left the board laying on the beach. The sun heats it up, the air inside heats up and since the board has been glassed and sealed with epoxy there is no where for the air to escape. This air expansion can cause the decking to delaminate off of the support ribs ot for the decking to split or crack. At least that is the theory behind the vent. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Bmac Posted April 1, 2020 Author Popular Post Report Share Posted April 1, 2020 I've had this build on my to do list for a while and I put it off, and now I remember why, because there are so many glueups. I've already been through two 16 oz bottles of TB III. So @Chip Sawdust is right, this does seem to be going slow. But I have made progress so here's the update. Top deck is done so it was on to the bottom deck. This glue up is a little more tricky since the top deck prevents getting good clamping pressure onto the ribs. So some creative clamping did the trick. Center board is the first to be glued; And working my way out from there; Once I got most of the lower deck glued up I wanted to get the nose boards put on. Started with cleaning up the front of the board. Before cleanup; After cleanup; So now that I have a nice surface to glue to I started with adding my boards. In this pic you can see I was able to tie my clamps into the board frame where I had not yet put my decking on. This worked out great and I don't think I could have done this as effectively if all my decking was in place. Also I left the first boards very proud of the deck. I used this lip to glue on successive boards. So then it was a matter of glue up after glueup, alternating 8 boards. Here's the end result with some rough shaping to get the nose boards flush with the deck; Next a little rough shaping of the nose. Really like as I shape and round the front that the light color paulownia peeks out from the cedar; Now on to the sides. First I need to flush up the deck and the frame and make the top deck even with the bottom deck; Now that I have a nice surface to glue too I start adding strips; In this pic you can see I'm adding a second strip to the first strip. After getting two strips added to the top and bottom I'll "connect" the top to the bottom with 1 last strip, then it will be all closed up. And finally, here's how the tail is shaping up; So I have got a lot done but it does feel like slow going. I can get a couple glue ups done, then I need to wait a few hrs before moving on. So in between glue ups I've been working in my yard. Just redid my garden beds. So I have been productive in more ways then one; Thanks for looking. 9 Quote Link to comment Share on other sites More sharing options...
Chip Sawdust Posted April 1, 2020 Report Share Posted April 1, 2020 @Bmac I was teasin you about having it done because you tend to get stuff done so quickly. This would take me a year and a half, and I’d have to save up to buy all the clamps you’re using! Now where are you gonna mount that 5HP outboard? Doesn’t look like you’ll need a long shaft so that should be easy to find.... I’m thinking this will be fun to waterski behind due to the small wake.

pkinneb Posted April 1, 2020 Report Share Posted April 1, 2020 Very nice!! So I assume you will glass/epoxy this so it is water tight, is that correct? Quote Link to comment Share on other sites More sharing options...

Popular Post Bmac Posted April 5, 2020 Author Popular Post Report Share Posted April 5, 2020 So where I left off with this project I was gluing up the "rails", or the sides of the board. If you remember I added 2 strips the length of the board, staggering them and then connected them with a third and larger strip. So now that the glue ups are finally over, it's on to shaping. And believe me i'm glad the glue ups are over! So for shaping I'll use primarily just a few tools, the RAS doing the bulk reduction, rasp refining the shape, and a sander with an interface pad on to smooth; With the RAS I can get the shape pretty close, here's a pic of a small section of rail where the RAS still has some reduction left to do, but you can see how well it's done on either side of the unreduced area, you can also see the 3 distinct strips and how they are staggered, or stepped; Here we are with the RAS work completed and if you look closely the outline is not perfectly smooth. The rasp work will fix that; Now here are some pics after sanding, you will see 3 different results, first in this pic you can barely tell where the 3 strips begin and end; in this pic you can see the strips but the joint looks tight; In this pic I didn't get the joint closed up as well as I would have liked and you can see a very pronounced glue line; Now I'm not happy about that last pic, but the glassing and epoxy will take care of that. In the boards I've done, I've found it's very hard to close down every joint the whole length of the joint when you are curving and bending long strips into place. You just never seem to have enough clamps. Finally here are a few pics of the final shaped board; What's next is, glassing, adding the fins, vents and handle, then a final coat of epoxy. Oh, and then I need to make a paddle, or paddles rather. Thanks for looking. 10 Quote Link to comment Share on other sites More sharing options...
Mark J Posted April 5, 2020 Report Share Posted April 5, 2020 Why more than one paddle? Quote Link to comment Share on other sites More sharing options...
Bmac Posted April 5, 2020 Author Report Share Posted April 5, 2020 22 minutes ago, Mark J said: Why more than one paddle? Good question, paddles are very dependent on length for individuals and their height. Ideally you want the paddle 9-10” longer than the person’s height who is using it. Also, if used in the surf you want a paddle that is shorter than one you use in quiet water. Since my family members are different heights and we expect to use it in the back bays and in the surf I’m going to make 2 different paddle lengths that hopefully cover those different uses and heights. My one son who will likely use it in the surf is taller than me by about 4” and my daughter who will likely use it in the bay is about 3” shorter than me. So if I use my height and make two paddles based off my height I should have my bases covered. Also, I have to make a jig to bend strips to form the paddle, so if I’m doing that I figured may as well make at least two, and if it’s simple I may may more. The bend will be approx 10 degrees at the junction on the shaft and the paddle head. 1 Quote Link to comment Share on other sites More sharing options...

I know you would need a long bag but it might solve the clamp shortage. Well I'm not sure, never used a vacuum bag but this is a cumbersome thing. Also the pieces/strips for the sides often need positioning after each sucessive clamp placement. So I may have a 5 ft strip, glue is applied to the strip, clamped in position at one end, other clamps to be used are lined up ready to go, next clamp placed, strip positioned, clamp snugged down. So on and so on, some strips may need 20 clamps. Often I'm bending the strip in 2 directions, around the board and to follow the sweep or curve of the board. If a vacumm bag could be used I like the idea of even uniform pressure from all directions that is offers. Quote Link to comment Share on other sites More sharing options...

Popular Post Bmac Posted April 8, 2020 Author Popular Post Report Share Posted April 8, 2020 Well I'm in the process of glassing and epoxy coating the board. At the same time I'm glassing another surf board with my son, I had built that earlier this spring. I'm getting sort of tired of this build, I miss my chairs and the glassing process and sanding process is somewhat tedious. So as a distraction I started on the paddles. For the handles it will have a 10 degree bend at the paddle head, the handle will be somewhat oval, 1.5" by 1.25", and the top of the handle will have a "T" type end. Started with the jig for the 10 degree bend; Strips of paulownia and cherry where prepped about 3/16ths thick and glued; All glued up. Made this blank 3.5" wide, I'll be able to get two handles out of this blank; Jointed and sized both handles and now onto the paddle head. cut out pattern for shape; Using strips of red cedar and paulownia here; Glued and then shaped; Still need to shape the handle more and work on the "T" top. Thanks for looking. 9 Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted April 8, 2020 Report Share Posted April 8, 2020 How does that angle improve usage over a straight blade? When you mentioned a bend, I was expecting it to be on axis perpendicular to what you show. Obviously, I don't live near the water....

Chip Sawdust Posted April 9, 2020 Report Share Posted April 9, 2020 Seems it would give a little less pull on the front of the stroke and a little more push in the back end of the stroke. But I’ve never paddled a standup board. In my canoe days my paddles were straight, and the old J stroke was de rigueur. But again, that’s sitting down.

JohnG Posted April 9, 2020 Report Share Posted April 9, 2020 My canoe paddle is bent like that too. It takes a bit of adjusting to get used to it but it’s more efficient. You can keep the blade perpendicular to the water for more of the stroke. 1 Quote Link to comment Share on other sites More sharing options...

Is this a tried and true or your design? Well guys I build em but I've yet to use em. I'm following the tried and true design. It's my understanding, and hopefully my experience this summer, that the bend faces away from you when paddling. The paddle is supposed to enter the water in front of you and exit the water once the paddle becomes parallel to you. This angle allows for more efficient paddling, so I'm told. Doing research for this project I found a site on common paddleboard mistakes. Listed as #1 was using the paddle backwards. Now I'm sure you could make a straight paddle and have it work, but this is the preferred design. So as I learn to paddleboard this summer I may not know what I'm doing but at least I'll look like I know what I'm doing! 2 1 2 Quote Link to comment Share on other sites More sharing options...

You can combine your love of Maloof by adding a chair for the world's first sit down stand up paddle board, mid century modern edition! Or you could do something Queen Anne with the ball and claw feet white knucle grasping the sides of the board, or perhaps hanging six for the more lion hearted rider. 5 Quote Link to comment Share on other sites More sharing options...
Popular Post Bmac Posted April 14, 2020 Author Popular Post Report Share Posted April 14, 2020 Time to wrap this up and I'm excited to get my shop back. For the past week I've mixed more epoxy than I ever care to mix, and I still have a little more to mix. SUP has been glassed and epoxied, I also glassed and epoxied a smaller 6' board I had made last month. Just waited to do them together. Made 3 paddles and I still have some work to go on those but I'm waiting for another shipment of epoxy. So here's the final result, I'm really happy with it and I love the way the red cedar works with the paulownia, looks better than the walnut paulownia combo. Glad to get this huge project done. I knew it was going to be a big/long project so hence the virus inspired. Now on to another project. Thanks for looking. 6 Quote Link to comment Share on other sites More sharing options...
