Overhead laminating.

[wanagofass]

I've got some overhead laminating to do on a dash core and gussets, just wondering if anyone has any tips on keeping the glass on the boat and out of your lap?...

Lay up on plastic then tape it up and roll over the plastic.
Or bag it.
2 gantrys and roll the boat over

[Noah Burns]

bagging would be the easiest way to get it done for sure.

Boat is derigged, I may just flip it.

I have thought about using epoxy and heating the surface before laying then adding more heat. I haven't tried it yet just an idea knowing how heat affects epoxy.

There are folks with more experience than me, but I have done some of this. Some considerations:

- considering using a lighter reinforcement and doing it in 2 layers laid up after the first kicks a bit
- consider using a thixotroped resin, thickening your own a bit, or otherwise looking at the viscosity so it doesn’t drain out as much
- use rollers as much as humanly possible - brushes will drain more resin onto you than the glass lol.
- wear laminated Tyveks because you’re still bound to get a bunch of goo on you lol....

I tried many tips. It’s still hit and miss. I tried spray glue, rolling it in a bag, painting some epoxy on then waiting. My most reliable method appears to be thickening resin with cabosil, spread it on with a notched trowel. Then stick the glass up, squish it in well so it holds the stuff upside down, a quick cup of coffee and then wet it out. If it’s a big area, sometimes it’s ready to roll out straight away by the time your done. I still sometimes come out wearing it, like a grp ghost.

I work with epoxy so how I do it might not work with poly or vinylester resins, not sure. I take a paint brush and brush on a little thickened resin (cabosil). Then on a laminating table I lay up all the layers of glass onto a piece of peel ply with plastic under that, then I put it up into place and squeegee it on, peel off the plastic and then squeegee some more on the peel ply. I'll go over it with with a metal roller as well.

With the plastic i can stay pretty clean. I've never done really large laminations this way, but it seems to work well in my experience

For a larger strip (say 2' wide) the only way I have ever done it (and it's still a pia) was to roll some resin on the surface and let it kick off most of the way. Not wet but real sticky. Roll your glass the long way. Start at one end and stick the glass to the sticky resin for about a foot and keep the rest rolled up. A dowel rod in the center of the roll helps. Wet out that foot to get started. Then un-roll and wet out 1' as you go. One hand wets with a paint roller other hand holds up the glass. Easier to have another person help , but can also be done making a movable support (2x4) to hold the glass roll pinned to the upper surface to free up both hands. Mat is easy, 1708 is really a 2 man job unless narrower strips are used.
