Just the plastic ones that are usually used for applying bondo.



I like them because it is easier and faster to work the resin into the cloth.

This doesn't really show everything because it is a time lapse, but you should get the idea.

Again (my usual disclaimer), this is the way I like to do things and that doesn't mean it is the only way, it's just "my" way.

Here is some more on "my" methods... The wetting out part starts about 3/4 of the way down.

the thin cheap plastic cutting boards work pretty good too, & you can cut them into any shape you want.
put a nice radius on them for fillets too.

Looks to me like youre using epoxy. Will those squeegies work for vinylester?

[Callyb]

Yes they will. I thought you were using epoxy for some reason... I don't know what kind of times you have been getting until it starts to kick, you will have to make a judgment call as to whether or not you will have enough time to wet it out and get it in place before it kicks. Just remember that if you chill your resin you will get more working time and the faster you get it thinned out (out of the pot) the longer you have also.

[4shore]

Been getting about 45 min if i kick at 2% i would imagine a little longer today if its stays cool. Any concerns with using vinylester below 70 deg?

[Callyb]

I would think that you would be okay. I would consider the temps being to your advantage.

Just checking to see how you are coming along with the glass...

Hey thanks for checking up! I have been building up the isolated low spots as time allows. It has taken two layers of 1708 and i have a couple spots that will need one more layer and then I will be ready to lay the big sheets.

I have had varying opinions on how to do this from sources i respect for their knowledge.

1. Start small with the area that the skin was removed and continue to overlap until the entire transom is covered

2. Start with the largest piece and work back to the smallest to create a taper and then fill the taper

3. Build up the removed section only, bevel it where it meets the old, tape and fill that and then cover the whole transom with 1.5 oz csm and fair.

One more thing. I have about two gal of vinyl ester left and then i have to get more. My supplier is 2 hours away in norfolk. Is two gal enough to get this outside skin done?

You will have to figure out what you total amount of glass is going to weigh and that is how many of ounces of resin you will need, plus about 15% or so for waste.

Personally, I would do the lamination in the order of #1., but it can be done whatever way you want to do it I guess.

[4shore]

It's a 1:1 ratio?

that seems too easy!

[Callyb]

Yup, sure is... The ideal lamination is 50% glass, 50% resin.

use the cheap roller covers from box store like Rick said. I don't use the foam ones use the hair ones they don't melt or fall apart. 70 should be fine but pay more attention to how cold it's going to get at night. If its going to get 60 or colder get some visqeen and drape it over the area your working and place a halogen work light in there to keep the temp up. I have done this plenty of times this spring with the yo-yo temps.

In preparation for some big layups im doing i was checking over some smaller patches on the transom that i had laid to even it up and noticed small pin head sized bubbles in some spots. i guess it off gassed on me when i wasnt watching. They are kinda dispersed thru the patch area, no big collections in one spot. I wouldn't think it would be a big problem right?

Any tips for reducing these off gas bubbles when doing large laminations? I'm getting ready to lay down 2 layers of 1708 and 2 of 1808 on the transom tomorrow.

After I do my layup using a roller I come back with a roller with a bristle brush on it. It helps to release all the bubbles through the wet out glass. You can pick one up at a fiberglass supply store. It works like a charm and really speeds the layup process.

[4shore]

U do this between layers or after youve layed it all?
