E-Board

Special ordered over three months ago, and just in time for the new year, my two sheets of King E-Board came in. This is from the same company that makes King Starboard (a handy, plastic material that can be cut and assembled like plywood). E-board is designed to simplify wiring and plumbing installations. It is …

Enter More “Traditional” Building Materials

Marine plywood. Compared to Coosa Board, plywood is cheaper easier to paint holds screws better but it is also heavier weaker with bonds using epoxy more messy to cut Plywood will be used for semi-structural/non structural uses where there is no bonding/glassing to the hull. Moreover, the really cheap, …uh, ‘less expensive’ Chinese marine plywood will …

Coosa Conservancy

When you work with anything that involves cutting, you end up with scraps and leftovers. When it is stuff that is as expensive as Coosa board, you tend to be reluctant the throw out ANY piece that MIGHT be useful for something in the future. As a result, I have a whole bin full of …

New Materials

This is a new building material from those wacky, but always innovative, Aussies down under. A high density, closed cell, polyurethane substance. Very stiff and easy to cut. It has some interesting qualities: heat formable easy to cut 100% waterproof ready to paint provides thermal and acoustic insulation I can think of a few places …

New Materials

Things are getting to the point (at least in the main salon and forward) where we need consider a different building material besides Coosa Board. In this project, Coosa board has been used for portions of the interior structure that is glassed to the hull. Reasons for Coosa over plywood are 1) resistance to rot …

Gotta Love Modern Chemistry

Methacrylate, the new ‘Super Glue’? A two part structural adhesive that will bond just about anything to anything (except rubber). Different formulations with cure times from five minutes to two hours. Very, very strong. Stronger than any of the resins, epoxy or otherwise. The most recent application on this project was the finishing of the …

Got Glass?

300 Pounds of Fiberglass We ran out of bulk glass last week. The last time we ordered this stuff it was sold in quantities measured by the yard (that order was about 50 yards). I thought that was a lot then, but with less than 25 percent (approx) of boat project jobs requiring glass complete, …

More about this Coosa Stuff

If you have been following this blog, you know I rave about this Coosa board. A glass reinforced polyurethane replacement for plywood. cuts easily light resin really sticks to it does not absorb water will not rot strength comparable to plywood (actually, a little less in some characteristics). Well. there are a few other things …

More Fasteners, Fillet Strips, etc

Got some more fasteners. Stainless steel. Machine screws this time. With washers and nuts of various types. Square drive of course. Though I have run out of storage bins. Also got a box of fillet strips. These are foam strips that go under the glass tabbing of bulkheads and basically anything that glassed to the …

Glass Shop

A little more shop organization this weekend. Hung some pegboard to help organize the glass tools (rollers, mixers, scissors, etc). This week will see some experiments on resin infusion for glass over foam. The floor pads may lend themselves very well for easy setup for infusion. To set up the experiment, I tooks some scrap …
