Laminating / Vacuum Table

[capaworks]

In the process of building a laminating table for a boat project I just started. Table size is 5 x 10 covered with 3/4" MDF.

I plan on applying vacuum against the table for infusion and/or vacuum bagging so need a surface that will be robust. I've read that the formica/contact cement solution works in the beginning but the formica will begin to crack after a while and can also bubble. I figure this is a three year table so I'd like to do it right the first time.

I was considering rolling tooling gelcoat over the MDF with duratec to try and minimize sanding afterwards. Has anyone ever done this? I do not need to have a perfect finish since I will be spraying LP over the parts.

If there are any other thoughts on how to surface the table I'm all ears.

One fella suggested glass but that seems a bit risky and expensive.

Thanks,

Glass works but is delicate.MDF is very porous and you will need some kind of impermeable surface.You could apply Formica with Cascamite rather than contact glue.Alternatively,you could use a sheet of aluminium,which can be cleaned with Scotchbrite and normally gives a good release.

Thanks for the idea..

The woodworking guys use durabond 800 which is also a fermeldahyde-urea glue similar to cascamite.
Found a 5x10 sheet of ultra gloss formaica for $100. So we'll go that route.

You can use particle board with melamine if you replace it regularly, it's cheap stuff.
