advancing glassing technique

I’m starting to feel quite comfortable at glassing – at least concerning shortboard freelaps – it’s certainly a world of difference from the first couple of boards. I’m shooting a quart of resin with 15 cc’s at 19C (66F) – giving me about 15 minutes to get everything in place and a few more to catch any trouble spots… which is perfect timing for me on the shorties. A far cry from lightning fast, but it sure is a lot quicker then when I started glassing…

All things considered I’m happy with my progress, but what bothers me is that I’m still getting some dry spots… no more big areas, just those little spots that don’t fully saturate. I know it’s cosmetic, but annoying. I’ve made a lot of progress on them on my last few tries, to the point where you can’t really tell on a white board unless you really look… but yesterday’s had a deck fade on it which really makes them stick out more. This problem is certainly more frequent on the deck – two layers.

My basic technique is to dump about a third of my bucket on the center and quickly, and lightly, move it around, saturating everything up to the rails. I then let that soak in while I wet out all the rails. Next I come back to the deck (bottom) and rub the resin in with a firm stroke from the center out to nose/tail then rails (thanks PlusOne). You can hear the stroke. Then I wrap my rails. Finally I take what’s left in my bucket and smear a thin layer across the deck (you can still see the weave texture, just making sure I don’t leave those big ‘dry-er’ areas) and scout out any trouble spots.

It wouldn’t concern me, except that I feel I’m developing a good “flow”, I can move from step to step without thinking, things are feeling natural - I want to weed out problems now, before I fall into a habit. I have no idea how you guys are doing this in 8-10 minutes, I really feel now like I’m hardly missing a beat – with the exception of wrapping the laps, I’m sure I could cut a minute or two out of that.

Thanks for the help, past and present… sorry for the short novel.

RK,

Sounds like you are doing a great job! It takes me about 10 minutes to do short boards. I set a kitchen timer so that when it goes off I have about two minutes to “tidy up” the laps and nose/tail tucks. The resin I use takes about 8cc/qt - 70 degrees - 12 minutes! Perfect for my rhythm. I have been mixing in some suncure and once I get the kick from MEKP and all is well I throw open the door and uncover the windows. After about a minute I walk it outside and finish cleaning tools. Then its time to do the other side. Truly amazing stuff. No heat build up…just cool hard resin!

Those pesky dry spots seem to appear when I am really stretching the cloth taught with a firm stroke. In the nose area it causes the cloth to lift a little and suck air into the weave. I had been leaving too much resin in the lam so now I have been really working it tight and thin. Much lighter board is the result. I make a quick pass and look for these “dry spots” after the “bell” I also have good success with a yellow bondo spreader for flattening the lapline on free laps. the flatter it is the easier it gets to prep for the deck lam!

Good work.

Personally, I would’nt worry about how long it takes you to do a lam. It takes me 1/2 an hour to do a longboard by the time I fart around looking for dry spots and cleaning up the laps. Those little dry spots, you never seem to find them all. When I find them and if the lam is still green I mix a small brew and force some resin into them with a brush. This seems to work pretty well.Platty (David Platt)
