Hi there guys,
New to the board building process and currently up s**t creek with the glassing so I’ve a few questions.
For a bit of reference, I have shaped a
6’1" x 21" x 2 3/4" Retro Fish with swallow tail. The crack of the tail is about 4" deep. Fins poitions 7.5" from tail (swallow tip) 1.5" from the rail and a 1/4" inch toe in.
Using the Shapers Aus Fish building kit, and I’m based on the Gold Coast, Aus. Currently summer temps.
The shaping of the board and setting of the fins went pretty well for a first time… I think.
However the problem starts with the next step.
I have proceeded with the lam of the bottom.
A 4oz cloth, purple and white resin swirl and cutlap. I tape off the deck and flipped the board over, pulled my first sheet of glass, brushed out smooth and did relief cuts. I also added patches over the fins and a patch round the swallow tail crack.
I mixed approx. 800ml Shapers Laminating Resin with 2g Sunbake UV additive. I split this in 2 and added the white and purple tints to each cup respectively and then catalysed with MEKP catalyst at 1% ~ 4g per cup. I mixed well, and then applied the resin, running lines of each colour up and down the board.
I squeeged lightly to start and then applied more pressure. This process was a lot harder than all the youtube videos made it out to be. I persisted and tried to work all the bubbles out, however when it came to lapping the rails, id almost run out of resin, so i quickly whipped up another batch and poured around the rails and did my best at sarurating the cloth to tuck.
Anyway, i didnt work quick enough it all started getting gelified, so i got as much tucked and neatened and popped it in the sun for a couple minutes where it hardened pretty quick.
But what im left with is a bit of a rough cut lap with some bits of cloth not saturated with resin and some slight pooling.
My questions are:
If i sand back the roughest parts of the glassing and patch with a piece of cloth and some resin will this be okay to hot coat and gloss coat overthe top?
I found the catalyst worked very quick, (damn you aussie summer). Can I not add catalyst and just use Sunbake at the ration I have? Whilst working out of sunlight, have a little more time to get the lam right and then proceed to put the board in the sun?
For my filler and gloss coats…
What is the ratio of wax in styrene to resin? Can this be done with UV additive instead of catalyst?
And how much resin should coat one side of a 6’1" board.
Sorry for the War and Peace novel, im just welcome to all the advice.
