epoxy and fiberglass matt

[warthog5]

Melimene [sp?] is usually a thin sheet material, kind's like Formica which can be used too.

When building a layup table it need's to be made with material's that will not warp.

Typical for our use would be a panel that can be setup and taken down just laid on a few sawhorse's.

A sheet of decent 3/4in plywood and a sheet of 3/4in MDF [Mediun Density Fiberboard] glued together Then a sheet of Formica glued on each side with the exposed edges of the wood sealed should work well.

The Formica on the bottom side help's to keep it balanced and sealed from moisture.

Storage is important too and can be a pain with limited storage room.

I use the regular mold release wax to wax it. It's available from the fiberglass supply house's.

Strick use's a bunch of 3/4in MDF to build mold's, like the one for his leaning post and motor bracket.

He knock's 'em out quick. He's a mold building son of gun.
He's taken Bigshrimpin under his wing now, teaching him the ropes.

Ah....the infamous "Burro Brand" sawhorses show their faces once again. That means the California boys are busy mixing resin....and it aint for surfboards.

Looks like the cats out of the bag. Thats Bigshrimpin's project so I'll let him do the posting on that one. I've been holding his pic's hostage.

71kidcasper- To answer your question I let the duratec set up till it is still a little tacky then start the lay up. Never worked with gel coat. MDF makes good one off mold material.

Strick, If I wanted to use MDF for one off molds does it need to be sealed or coated with something so that there isn't any problem with release.

Is that a bracket that your building ???????

[warthog5]

Yep. I told he's a mold building madman.

Here's the 1st one Strick built.

RB - that's the MDF mold it's held together with epoxy and 1708 4" tape. The inside is all that matters. Seams are bondo and clay then the inside is coated with epoxy. The epoxy sinks into the MDF and dries hard. It needs to be sanded and coated again, waxed with part all or another mold release wax. Then you can layup the part.

This is treading on new ground for me . . . Chucks pretty much doin all the work and making me feel like I'm doing something to contribute (instead of just drinking beer).

The angles and the measurements were tricky. We drew the footprint on the back of chuck's 20sf to get the shape right. It's really going to look good when it's done.

I'm still at work now and I'll be here again sat/sun (my second 60+ hour work week in a row), so no worky on the bracket for me this weekend.
