Okay, so if you’re 200lbs, and you’ve got 5oz glass with NO CF inside, I’ll be safe, and do 5 6oz coats top AND bottom. :~) Just kidding. I think a 6oz S cloth on top and a 4oz E on bottom might be fine. I even thought about (heaven forbid) ship lacquer or something like it and just going for it… I’m going to err on the side of caution and glass them 6/4oz. As for the missile thing, I’m hoping that the balsa wood rails will be a little lighter and maybe more forgiving if I get clocked by my own board.
jase, interesting to hear about your resin , i have used seabase poly and silmar poly , silmar is clearer i think , what make of poly is it you are using, its certainly cheap at £3 per kilo, i have been using epoxy to do these balsa boards and they cost nearer £20 per kilo,
i am just finishing my 3rd balsa at the moment 6ft 1 ins , 5 lb , will post some pics when done ,pete
Not sure who makes it as I think I threw out the can from my last batch, I know it is from Birmingham and it is loads clearer than either Silmar or Seabase x7 (Seabase reckon theirs is clearer than Silmar). It’s a shame you hadn’t asked a few weeks ago as I was down your end of the country since the 14th until yesterday, I could have ordered some in and got it over to you. Next time I’m down is late October I think, or I could have a word with the Geezer who supplies mine but I think where he orders from just supply to the trade.
Way Cool Pete, you’ll be the first Swaylockionian I’ve met in person. Where about in Cornwall are you as I rarely get past Bude. I usually stop around North Devon.
i live in st austell , cornwalls south coast, newquay is 16 miles,where i surf mostly, bude is about 40 something miles away , there are some good spots up in the bude area that i used to surf when i was younger, heavy rock reefs that don/t show any mercy,
the south coast of cornwall gets some good surf in the winter,when you see pics of porthleven all the south coast is working then but you have to be on your toes because the swells don/t last very long sometimes only half a day,
i met a fellow sway in newquay a couple of years ago , Joe Hart from bornemouth but he is the only one so far ,could be time for an autunm sway meet!, pete
Just a thought on the glassing of your HWS, I’ve had a nose at the site, the timber work looks great, don’t risk it with going light on the glass. I used a single layer of heavy cloth (unsure of weight but way heavier than the 6oz I used last time) and have two or three stress fractures appeared in the deck and the board has only been used in light 2-3 ft beach break and despite my screen name I aint that big. This could be that my glassing skills are lacking a bit but personally, I won’t risk going with a single layer on the deck of my next hollow. I’ll get some photos of the damage up tomorrow.
I think you and I should trade screen names, as I am 275lbs (but I’m not fat, just built like a brick s**t-house). I have had many wooden snowboards, and I tend to break the wood on them by going stupidly big in the park with them (http://www.pbase.com/bootslondon/image/23213125.jpg). I think I’ll take your advice and we’ll do 2 4oz top sheets with them and 1 4oz on the bottom. I don’t think I’ll be doing any hard impact like that on ours, but, you never know how hard I’m going to get slammed when I don’t make my drop. One thing I do know about myself is that sometimes I’m a little more eager than I should be in all things, even bigger surf, so I know I’ll get some good falls in on my board.
g’day all, I’m at the start of building a hws at the moment, just went to the glassing shop to get some stuff, I was going to use carbon fibre to reinforce the insides of the skins but fond out that it was $54.00 1m by 1m!!! so i decided to get 6oz e cloth instead for $7.00! will this be ok to reinforce the stringer with and also to do the insides of the skins or have I made a mistake in being a tight-arse and not buying the carbon?! can i use this cloth to do my wooden fin as well or will you see the weave too much? I ended up going for epoxy over poly too, I also got a respirator and some other stuff too, left the shop with my wallet $285.00 lighter!!!
6oz will be fine for everything, CF is very expensive, but now you’ve got everything you need, $285 is alright for price considering all the left over stuff you’ll have for the next one.
Hey Robbo, I know that a lot of the guys here have built hollows without any reinforcement on the stringer or the inside of the decking matterials and they all seem to be fine with it. I think from my own limited experience that what you put on the outside is a more critical point. My last board was reinforced with C.F. on the inside (stringer and deck and bottom) so I thought I could go lighter on the outside, won’t do that again. Seems that the board really needed that extra layer of glass on the deck that I didn’t put on.
hey fat, so what do you think of a 6oz on the inside of each skin, 6+4 on top and 6 on the bottom? + reinforced stringer and outside sub-rails? I think that should kill it? anyone else have a comment on this please?
Proper job! Just fit a horn so everyone knows you’re coming.
I do think that the sub (that’s the same as internal, right?) rails if you follow the Paul Jensen method are super strong anyway and shouldn’t need any reinforcing.
The way I would do it is to assemble the frame and bottom skin pre-glass with good glue then fibre glass the inside so the bottom skin and frame are glassed together rather than just glued. Glueing the deck after reinforcing would be adequate, just make sure you don’t use the same shitty glue that I did last time. I did this the other way round last time aswell ie carbon fibred the frame to the deck and just glued the bottom skin, the bottom skin has since come away from the frame and is in need of drastic surgery. I’m sure if I’d done it the other way round it would have been stronger.
hey hicksy, yeah I had thought of not doing the insides at all but because I am making the deck up with many strips of timber instead of ply I need some way of holding them all together and this seems the strongest and most practical way. finished my glueing jig today, next up… laminating ply using epoxy to get the length required for the stringer, getting exciting now! will post some pics when I work out how!
yeah thanks paul, I really had my heart set on the carbon fibre but the price difference was HUGE! $55 L/m versus $7 !!! so ive got 10m of 6oz fibreglass cloth now, what are your suggestions as far as reinforcing the inside skins, I can get some 4oz too if 6 is too heavy?
i’m going epoxy some ply together today to get the length i need for the stringer, how long do you think i have to leave it to go off before i can start cutting and shaping etc… thanks for the advice

4 oz. is what I’d use…
