Faded- why was the hemp so hard to sand? I’m told carbon fibre is hell when doing laps- is it a similar deal?
Ben- Nice arty shots of the layup- keep 'em coming as you yourself have been known to say.
thanks Kirk !
here’s a couple showing what a laminating resined panel looks like , compared to a filler ["sanding’’ to you guys ?] coated panel …

two down , three more panels to go .
my head is spinning at the moment though , so I think I will go out and get some fresh air for a while [I cleverly managed to spill about 100mls of M.E.K.P. ]
cheers

Hi consafos,
haven´t sanded carbon, so I can´t compare it. The surface of the flax cloth was very hard and it was difficult to break up the fibers. Maybe this is caused by the fact that natural fibers expand when they are wet?? And, like said before, you get frayed ends, the cloth doesn´t cut as cleanly as glass will do.
panel no.7 …
…just 2 more to go now ! [onshore winds , a godsend for getting fibreglassing done !]
So, all up , it “should” be
a pair of G7 fins
two pairs of G3 fins
one pair of canards
and perhaps a single hemp , or ? carbon fibre inlay ? back / single fin [I’ll have to see how the resin / cloth supply is stretching , by the time I get the next two panels done …]
cheers !

Roy,
Did you do peel tests on those fabrics? I tried acetate cloth on the weekend - strong colour ,easy wet out, low resin use but… peeled off balsa and glass like tape. Maybe I should wash it first?
Chip, man! you are looking way to organized. looking good… Hemp! Hemp! Hemp! just wondering what do you use to cut your fin shapes out with? do the blades wear out faster when cutting hemp fins? seems carbon fiber would be hell on blades…
Chip, I only read the first 3 and the last post so if any of my questions were answered earlier disregard this reply…I hate to read. more pictures please!
cheers!
g’day ben !
good to see ya back “on board” , mate !
Me , "organised " ?!!
oh geez… that’s a worry !
[funny how cropped photos don’t tell the WHOLE story sometimes] …if it makes you feel better shippy , I spilt the acetone today [last time …I spilled the catalyst ?!] .
What IS it with me and dangerous chemicals , I wonder ? [… I’m just glad I am not a scientist / lab technician , or something haha ! [disaster waiting to happen . ]
Regarding fin ‘cut outs’ ?
I use “carborundum” blades to cut out my fins , with an electric jigsaw. (The blades look like this …)
I haven’t ever had a problem with cutting out carbon fibre fins before … but then again , I only put three layers of carbon [max] into a 30 layer clear panel . It might be different if I was doing say 25 layers just of carbon fibre ? …I’m not really sure …
Regarding cutting out the HEMP fin panels …
…I am waiting to lay up the ninth fin panel , before I template the remaining three panels . Then I will have a "cut out morning " , some time soon [I will do it <span style=“font-style:italic”>outdoors</span> , this time , though !]
cheers
ben
just for you , shipster !
…panels 7 and 8 , one more to go now !
and just to put your mind at ease , Ben …
if you think my “kitchen sink work bench” looks organised , or tidy , or something similarly unmanly …HERE is what my loungeroom [about ten feet away from the resin pit] looks like …
bonus bookshelf , 7’ singlefin , and desk shot …
enjoy !
…hicksy , lavz , popeye , and kiricore have all witnessed it first hand , poor guys !
Hi Pinhead,
I don’t think I have ever used acetate cloth (not sure, does acetate = Rayon ?), but it’s always a good idea to wash the cloth first to remove waxes and stuff. Also are you laminating the cloth over glass? . . . if the glass layer underneath is cured epoxy then that might cause the cloth to peel off due to a poor bond . Wouldn’t it be better to put the coloured cloth under the glass?
Cheers
Roy
Roy,
Acetate is similar to rayon:
http://en.wikipedia.org/wiki/Cellulose_acetate
Yes, using it under glass. I’m laminating acetate and glass onto balsa. It’s very slick and shiny and not very strong. I tried polyester,it had very good peel strength - actually tore the balsa out, but sucked a lot of resin.
BTW saw this M5 stuff on Wikipedia - anyone know anything about it?
Chipper…I spy, with my little eye…an Oneula DVD. 
Anything good?
well spotted
it’s “vac bag board building”
very very good !! [I’ve only watched it the once , a mate has been trying to figure how to overcome the “regions” thingy …]
yep, bernie is the man !! thanks heaps mate !
cheers

update …
[bottom photo]
l to r:
back row …
GS type template [x2]
G6 template [x2]
middle row …
carbon fibre thruster side fins [x2]
GS or slightly larger version [x2]
front row …
2 canards [to go with the G6 , or GS templates]
to be continued ....[cut out time , next week]
cheers !
ben
for those wondering …11 panels completed , five still to go , so far …
I’ve still got to make a matching blue checkered fabric inlay GS template .
Then , maybe …
a resin swirl GS pair ?
Another carbon fibre GS pair ?
And a hemp BACK fin , to match the two G6 side fins … this will need to be a finboxed one , for my “bushfire” and “prawn” fishtail boards …
Once they are all layed up , and templated , and everyone is out , one day … then … cutting out time !
cheers
ben
Hi Ben,
Any progress on the fins? Looking good so far!
I wanted to update everyone following this hemp thread on what I’ve found in Santa Cruz. They folks down at U.S.Hemp on Pacific ave don’t have any of their ‘special weave’ in stock. They can place an order, but it’s an minimum of 300 meters, or over $5000. I’m trying to see if I can get a sample.
Meanwhile, I have a longboard refurbish that I’d like to laminate with hemp, and am going to have to place an online order. I’ve read the hemp threads from the archives, but wanted to get a little more input if possible. It seems that because the weave is so tight, it doesn’t wrap the rails correctly. Would it be better to get a looser material, more like t-shirt material? Or something stiffer, like a tight linnen weave. Any suggestions would be great, I’m probably going to place an order today.

I’m trying to get a new type of industrial hemp, made possible by new enzyme treatment processes…it’s not available yet but ill keep you guys posted. Might need a big order to get some. It should be very strong and hopefully relatively inexpensive.

hi Pat !
nah , not yet …
still waiting for everyone to go to work , so I can use the power saw and grinder [outdoors]

that seems a lot of hemp for them to order …can they not get smaller rolls / samples ?

I still haven’t glassed foam curves with it yet , so I am not sure . …‘Yoshio’ …where ARE you , mate ?? ( And , I wonder what postage on a few metres from aus to usa would cost ??)
Quality effort on the fins chipfish.
This may help i dunno. if you turn the fabric 45* so the weave is diagonal to the length of the board it will wrap around the sides much easier, its called turning the fabric on the bias, we do it in upholstery all the time to help create complex curves with one sheet of fabric. so if the panel is big enough to fit you should be able to do this on the longboard it may even work at 30*, just alternate between 30* and 60* on different layers.
