Nice work Rob, thanks for the inspiration and I appreciate your craftsmanship. I'm working on a board now, and it's nice to pick up a few tips from you :)
hello, well done job. I would like to know if is better a spray antiskid than roller paint antiskid and the real difference between salt as you used instead of quartz powder. Thank a lot. Carlo
What were the problems you had with this kind of construction after using the board heavily? Did the Styrodur / inner glass layer delaminate in some areas?
Hi Rob. Great videos thanks. Love the music, but aren^t you getting on a bit to be so speed all the time ? What are you taking my friend ..... Happy Xmas - lots of wind and a very good new year. PS: I have a factury nearby my house that makes glass bottles. The very best antislip for surfboards I found is finely crushed glass (microns) that you can pass through a sieve on top of wet epoxy. Its very durable and "abrasive", but salt is good too I suppose. Cheers.
Hi Rob, Very nice and inspiring videos on windsurf board fabrication! I like your workshop! I am curious what is the bill of materials and how many hours does it take? I am thinking to start eventually making boards as a hobby. Also do you have some good references (websites, books) on making windsurf boards ? Cheers, Dominique
De gebruikte verf voor dit board is watergedragen (gewoon van de Gamma) . 2 componenten lak zoals DD lak is wel sterker, maar het voordeel is dat je het heel gemakkelijk kan bij werken. De bodem heb ik na 1 jaar gebruik bij geplamuurd (krasjes en deukjes ) en opnieuw gerold. Ziet er weer uit als nieuw.
Hey Rob, from the looks of it this is not your first board and for the most part you're doing it just as I would plus some pretty clever ideas I'll definitely copy in the future. I just don't understand why you're using "wrong" materials when proper ones are easily accessible. Styrodur (XPS) is not a good sandwiching material, apart from being too soft it's also prone to venting gas throughout its life making it prone to delamination due to pressure. You can get Airex or Divynicell or other expanded PVC sheets easily in Europe (where I'm guessing you live). It's bit more expensive but not so much to make it worth mucking about with XPS. Also salt as anti skid? Acrylic dust is available (I can usually find Veneziani around here) and unlike salt it won't melt in contact with water. I can't really tell from the video but it seems to me you're not overlapping your glass on the rails from bottom to top and vice versa. You should really have a nice overlap of top and bottom laminate to make sure the rails are as strong as possible. You're also missing the breather fabric when doing vacuum bagging. I don't know how much that black stuff you use instead of peel ply can soak up - maybe it does the job, but to get a good resin to fiber ratio you need the breather to soak up excess resin. Also, try poking a grid of small holes 3-5cm apart in your sandwich core material (with a hypodermic needle), that way excess resin from the inner laminate can be sucked out as well. Happy surfing and building :)
Awesome videos. Great looking board and cool name 🤘

Awesome video and music!!!! Thumbs up!!

Rob, you never said what kind of paint you used?
What were the problems you had with this kind of construction after using the board heavily?
Did the Styrodur / inner glass layer delaminate in some areas?
Hi Rob, please, what is better to use before paint? After I laminated some repaired cracks. Epoxy with microballoons or polyester filler?
Big cracks first with epoxy/microballoons and than filler. Small cracks and dents only with filler.
Thank you for fast response.

hey Rob, wat voor verf gebruik jij voor een epoxy board?
De gebruikte verf voor dit board is watergedragen (gewoon van de Gamma) .

Rob Rock Windsurfboards Super, dank je wel. Ik keek al naar allemaal dure vsrfsystemen, hoeft dus niet! Oud course race board, veel verf nodig...
Wel even een test maken! En echt heel goed schuren.
Rob Rock Windsurfboards Zal een stukje testen! Bedankt voor de tips. Hopelijk in het voorjaar knallen op Meerwijck!
zou graag eens contact opnemen indien mogelijk een mailadres of iets dergelijks?
good job and clever 5 lbs too heavy though,and wear a respirator! thanks for sharing
I had to silence the music, to me its awfull...but what you are making is like a piece of art. Good job!
Nice job but you have the scale on a carpet. Meaning that board is heavier than it shows on the scale. You should have putted in a tile or concrete
