If I glassd a shortboard with say, a yellow opaque tint, can I just do a regular glass job without taping off and cutting laps? Are there any drawbacks such as seeing the thready laps, etc? Thanks- ryan p.s. How many cc’s of mekp would give me 30 minutes until gelling (about 3 quarts of resin), at 70 degrees?
Why in the world would you do either of those two things? You would have record breaking air and your board would be REALLY heavy if you kick your resin that slow. I think you would see a rough edge on your glass job if you don’t tape and cut. Why not just tape and cut and play it safe? I have done boards with a opaque bottom and a clear deck and ONCE I didn’t tape off for the cut lap on the bottom and I could totally see an inconsistant edge from the clear lap. Had to re-do the board. Maybe someone else has had better luck.

As for the 30 minutes before curing, I don’t necassarily need that long, just long enough to glass it correctly. I have pretty much only used UV resin until now and had all the time in the world. Switching back to catalyst, I just don’t want it to go off halfway through. Unlike some people on the forum, I am definitely no pro.
Ryan: In reading through you original post I think one thing need to be clarified. Ft. Bragg’s comment on the weight factor was based on your original comment concerning a laminating a short board and questioning the proper catalyst volume for “3 quarts”. This is way too much resin for a single side on a short board (say 6’6") hence her comment on the weight factor. 28 oz.- 32 oz. is more realistic and you will still get the floor wet. As far as catalyst goes it really depends on the conditions you will be using it in. 70 degrees is ideal, and 1% catalyst by volume as the standard. Hot weather=less catalyst, cold weather you either heat your resin or risk more catalyst and styrene to thin. Once you get out of the 65-80 degree range you can be in for surprises. (humorous to some and painful to others). By all means mix up a test batch WITH the pigment you will be using, take good notes and go from there. BTW- Ft.Bragg is THE_LAMINATOR from what I’ve seen, I hope we can count on her as a regular around here. TS>>> Thanks for your input.

Ft. Bragg- How does an extended kick time on the lam affect the overall weight of the finished product? P.S. Your input and obvious skills in this area of board building are certainly a welcome addtion to this group. ;} Tom>>> Why in the world would you do either of those two things?

I was just quoting from a few very famous people who I learned the ropes from. The longer the resin sits on the foam with out “Kicking”, the more it has time to soak into the blank hereby creating pin aire and a heavier blank. I also believe that if you kick the resin too fast that you won’t get a superior bond. Thats just a febale point of view but it really sounded good to me at the time. By the way…I WILL be starting to lam a few days a week as soon as I find a small toxic site to do it in. The several shapers here in Fort Bragg are…lets say…anxious to help out. Lates.
Mil gracias, it makes sense to me. But I meant what I said, you are undoubtedly missed by the brothers down south who relied on your skills. Thanks for sharing with us and I wish you the best. Tom

I do realize my original post of “3 quarts” was way too much. I am here simply to learn from people with more experience and wisdom, and truly appreciate all the information that is offered. I will definitely test it out first!
Ryan: Keep firing those questions, if you noticed we both learned something from your post. The issue of longer cure time causing unwanted weight in the lamination was new to me. I’m always humbled by the quality of talent that contributes here. Thanks for a great post. Tom>>> Hey Tom, yeah I meant no disrespect to the laminator at all.

we do miss you leslie but could you settle on a name, i would hate to accidently respond to the wrong laminatin woman.

I was just having fun and I thought that NOBODY would know who I am but I underestimated the power of the male thought process. I’ll stick with my email name. But NO heckling!

Will work for Money. Hey, I’m starving up here!. Work to be had but no place to do it and that means lots of beach (If you can call it a beach)time.
