Surfboard Shaping [2 of 2] Rail Bands and Bottom Contours

Shaping a shortboard single fin. Surfboard dimensions are 6' x 20.5 x 2.5. The bottom contours are single concave to double concave to vee off the tail. I've only shaped a handful of boards and am not an expert but this shaping process works for me. I'm still getting used to working with a planer which is why I also shape by hand using sanding blocks to help with accuracy.

I love surfing, building with my hands and making videos. Bendheim Boards is my outlet to fuel these passions. I'm self-taught and am not an expert, but these videos show the process that works for me. Follow along for new videos every month!

I am so happy I found your Channel I wanted to find a shaper on KZbin and here you are! Lol this brings back memories of when I was a kid watching Juan the owner of Western Flyer shape boreds. my dad was really good friends with him. I have a board he made that is 2 of 5 that he did for him and a few of his friends called the Siesta Key Edition its a 6'x2' noserider ill never get rid of it as long as I live

[@lugocota8292]

Looks awesome! You should try lowering your side lights so they're 5 or 6 Inches above your shaping racks. It will make a massive difference. 🤙

[@BendheimBoards]

Thanks maybe I’ll play around with them a little.

[@wolfhawaii1]

Nicely done, the planer got a bit hungry on the concave, but good recovery.....you may want to do a final plane pass on the stringer after final sanding just to make sure it is not a high spot in the glass, to minimize sanding issues. I did around 750 mostly longboard shapes in Hawaii in the 90s and early 2000s, got the urge to make myself a couple of new ones.

[@BendheimBoards]

Thanks that’s good advice. I’m still learning so I love hearing from other shapers. 🤙

I’m a little late, but I’m loving these videos. I’d love to get into shaping, as I’m jack of all trades kinda guy. Any “beginner essentials kit” you’d recommend, and what grit sandpaper are you using to hand sand the rails? Than you for your time and the videos. Great work!

Hey man, always good to see your videos. Questions for you, where did you learn to shape? Did you learn alone? Do you have any tips or how can I find advice to shape my own? Appreciate mate!

[@BendheimBoards]

Thanks! I’m mostly self taught and learned through research online and watching videos on KZbin. I took one class from a shaper as well. Check out the links in my video description for a few helpful references. It would be great to learn under a shaper but I didn’t have that luxury. You can also ask questions at the supply shops you buy your materials from. The more boards you make the more comfortable you become. Good luck!

[@birabito5701]

Teacher, your class is amazing! Is the bottom deck line measured as far inside? Thanks!

[@chrisomahony851]

Tanner, awesome videos man, super helpful. Might be dumb question, but what is/ how does one craft on of the pencil set ups you got? Did you have to make yourself or is there some sort of follow along to DIY one? Either way, keep making content!

[@BendheimBoards]

There’s no dumb questions man! Here is what I used: Marking gauge: www.foamez.com/product/e-z-marking-gauge/ you can make your own out of scrap foam. Hard to explain but you basically make an L shaped piece of foam and punch the pencil through the top of the upside down L. Hope that helps.

[@jamesleigh7104]

So cool Bru! Next level. Did you keep dividing the rail contours in 2? Is that how you knew where to draw those lines?

[@BendheimBoards]

Thanks! My rail mark was 1.25”, deck marks were 2” and 4”, tuck was 1/2”. After that, yes I just keep dividing them in half and can freehand draw the lines by just eyeballing it.

[@jorgetapialara7837]

Puedo usar cepillo en poliestireno (eps)? Muy agradecido por la enseñanza, lejos es el mejor video. Sería genial que hicieras uno shaping en eps.

I prefer PU blanks but maybe one day down the road I’ll shape an EPS blank.

[@gonzaloahumada3630]

Hey Tanner, thank you so much for the video and knowledge shared. i saw that the rails style or type you did is 60/40 but im not sure how to measure or get the type of rail done. how do you know the measurements for the rails?

WOW TOP surfer 🤙🤙🌊🌊🤙🤙🤙🏄‍♂️🏄‍♂️🌊🌊🤙🤙🤙

[@lorenzocanlas5253]

Thanks for sharing this! A few questions: 1) approximately where did you mark the end of the concave with a pencil, and how much further before you start the vee? 2) do you measure the depth of concave or vee? Thanks!

[@BendheimBoards]

I just eyeball it. I overlap my single concave into a double and then to a vee at the tail. Depth between 1/8-3/16. Check out this video: kzbin.info/www/bejne/pGLFgmmMbNSrors or these instructions might help: greenlightsurfsupply.com/pages/surfboard-building-guide-page-2

@@BendheimBoards haa thanx gonna check that !!!

[@worstenbreaud]

Hey Tanner, I've watched your videos and shaped a few boards. I'm still struggling to understand the bottom tuck part, especially when using the greenlight charts because they use tucks like 3/4".. but if I measure and cut off 3/4" that's quite a big chunk and my rail will end up ridiculous 😂 what measurement do you use for the bottom tuck and how does it differ on short/longs

[@BendheimBoards]

It just depends on how boxy or knifey you want your rails to look. I usually try to keep a 1/4" untouched band around the outline of the board from the first rail mark down to preserve the outline before screening my rails. Yes, 3/4" is a very thick cut, I'd usually start around 1/4" tuck and then go off feel under your arm to make any further adjustments.

[@ExpandYourHorizonz]

When drawing your rail marks, what do you do on the tail and nose of the board when the thickness foils out? (It looks like the deck marks you did nose to tail?) And for the tuck, do you stop it a certain distance from the tail in order to maintain the hard bottom edge of the rail? Thanks for these videos, they rock!!!

[@BendheimBoards]

Thanks man! Great question. You have to gradually taper your rail marks to follow the thickness of the board. So my rail lines on the tail and nose are narrower - especially the nose. I mostly just eyeball it and freehand draw it rather than measuring it on the nose and tail. You are correct about the the tail edge. I mark where I want my hard edge to begin on both sides so my tuck line doesn't sand into it and then just make a gradual transition from the rail to the hard edge.

[@ExpandYourHorizonz]

@@BendheimBoards thanks for your answer, definitely helps! Last board I botched the rails so this next one I'm gonna try utilizing these techniques!

[@BendheimBoards]

Best of luck!

[@jacksaveall7640]

I followed you on Instagram... I want to get into this because I love surfing and this looks like something I would really enjoy... for foam blanks I was looking at Marko foam, is there another brand I should use?? also do I need the custom electric planer, or could I just find one on amazon and it would work.

[@BendheimBoards]

Awesome, thanks for the support! I use US Blanks, but Marko foam is just as good. If your worried about cost, I would start with hand sanding for your first board. Its a lot more work, but less room to make mistakes when hand sanding. The WEN planer I have was only $42 from home depot. Its not as good as the others, but I do a low volume of boards and it gets the job done.

[@vandecasteeletheo8249]

Hi tanner! Any advice on how would you do 50/50 rails? I kinda don’t know how to do this....

[@BendheimBoards]

The middle of your rail is the apex and the rail bands are the same measurements on the top and bottom of the board. Checkout Greenlight’s website that has lots of measurement info for rail bands.

[@jacobmirels9073]

Sick video man! What were your nose, center and tail measurements?

[@BendheimBoards]

14.5” 20.5” and 15”. It’s a blending curves template

[@jacobmirels9073]

@@BendheimBoards right on man! That tail looks wider than 14.5" but its probably just an optical illusion from the outline. You ever put a Vee bottom on a short board?

[@BendheimBoards]

@@jacobmirels9073 Nose is 14.5" and tail is 15" sorry, should have specified. Yeah, this board I did single concave, to double and vee out the tail. Wanted the vee with the single fin setup.

Heelo amizing work , i wated to ask you if i want to start shape how can i choose my dimensions for shortboard

Find a board you like and try to replicate the dimensions. You can use blendingcurves for a good outline template.

When measuring out your rails, how do you get those numbers and calculations so you know where to draw the lines and such? Additionally, what is that tool called that allows you to draw the lines the same length
