Fin lamination

A NOTE ABOUT GLUE: If you read some of my earlier posts regarding my mock-up test hull, you'll know that I often used Titebond II to glue things instead of epoxy. That was because that boat was never going to see water. This time I am almost exclusively using epoxy. This is the real deal boat and will be sailed, so a waterproof adhesive is required. Specifically I'm using WEST System 105/205. Read more about it here .    ------------------------------------------------------------------ I started to laminate the fin tonight. Just the inner core made from 1/8" plywood, and then the first side of ply #2 made out of 1/16" plywood. You need to take extra caution on the first three or four ply's so that it remains really flat. The last few ply's you can stop using the 3/4" MDF form, but use it for the first several. Use the excess epoxy: Then use the extra epoxy to clear coat some of the frames. Between laminating the fin and rudder, you can easily ...

Small batches of WEST System Epoxy using marked syringes

I am using WEST System® epoxy for this boat, but I’ve also had great experiences with System Three®. Whatever brand you use, be sure to stick with it. Never mix and match resins from one company and hardener from another. Stick to one brand and follow their instructions. Specifically, I am using WEST System® Group ‘A’ size cans of 105 resin with their 205 hardener. This epoxy uses a 5:1 ratio of resin to hardener; therefore, you’ll buy a quart of 105 resin and a much smaller tin of 205 hardener. They are usually sold together. Using the WEST System® Mini Pumps: (They still actually put out a lot of epoxy!) I use their ‘ Mini Pump ’ kit which includes measuring pumps for each can. They are easy to set up and use, and will dispense the proper 5:1 ratio. CAUTION : System Three uses a 2:1 ratio, and some brands use a 3:1 ratio. Furthermore, each brand has its own ratios and you must follow them carefully! READ the directions closely for your brand. I assume you are using WEST Syst...

Rubber Band Clamping System for Planking RC Sailboats

I found a great way to clamp planks while making my Star 45's and Vintage Marblehead's. My building boards are 8" wide. I hammer in strong thumbtacks into the side of the building board. You could also use nails or brads. (See pictures below) The idea is that you can loop rubber bands over the hull, or through the hull, or around specific planks as needed to keep pressure where you want it. The rubber bands simply hook onto the tacks. See my pictures below. The pictures below are from a Star 45 that I built a few years back. Used the same technique then too. Good luck on your build! Peace!
