I am an intermediate surfer going to build my first board, because I think im going to be pretty heavy footed im going for 6oz and 4oz on the deck with 6oz on the bottom. The board will (hopefully) finish up at 7’6" and 21" wide.
I was going to buy this 6oz and this 4oz, since the 4oz is narrower than the 6oz, and going on top of it, their dimensions say it wont overlap. From what I understand this will weaken the rails, has anyone got any more input on this?
The length of your thumb is a perfect gauge.
Mine are between an inch and an inch and a half, depending on where you look along the rail… narrower at the ends, wider through the middle.
Just to touch on something implied in your original title and question. A standard overlap for a cutlap is 2 inches. The big fat cutlaps are 3 " and I’ve seen guys do 4 " which is completly ridiculous. Not retro and total overkill. A nice free lap is 1 1/2" or 2". You can do as little as one inch on a free lap. If I were going to skimp and do a short lap; I would also free lap my layer of 4 oz. . Lowel
Dobby,
I did not do the math but assuming that is standard 4 oz cloth, and your board is not 4" thick, the 4oz should be 27" wide and will definetly wrap the rail and make it to the cutlap. In the case that your laps are super wide, or the board ends up wider, just lap the 6oz over the 4oz.
The first layer of cloth is cut at the rail apex and serves as a full length patch, the top layer is the one that is lapped. Then when you flip the board you will wrap the bottom layer over too. This will give you two layers of 6 oz over the rail.
You want your top layers to lap around the rail completely. The extra material helps prevent dings and pressure dents from your hands, and adds snap resistance.
Ha yeah, I was being an idiot! completely forgot it would be getting trimmed down to size!
Thanks for your help guys
I didn’t go to the link but typically you are talking about glassing the deck with 27" four ounce cut at the bottom of the rail(not lapped), Then a layer of 30" six ounce lapped , The bottom which is usually done first would be done with a single layer of 30" six ounce lapped,
There’s your answer.
Thank a lot for all your great responses, hopefully my blank will be arriving later today, then I can get shaping
