Eva Too – Hull Fiberglass

(3rd of 3 postings today) When our children were young, my wife volunteered to help with food preparation for some school event which included an evening meal. She called a food distributor to explain her task and ask how many servings are in a gallon can of baked beans. The woman on the other end of the line answered, “Oh honey, that won’t be nearly enough.”

This boat is covered with fiberglass fabric that is adhered with epoxy. After making the hull suitably smooth, the fabric is draped on the hull, smoothed, and trimmed. The weave of the fabric is loose enough that it complies very easily to the shape of the hull. I was expecting ripples and pleats, but was very pleasantly surprised to see the fabric fit neatly. After draping, the instructions call for trimming the fabric to within 1/4 inch of the edges of the hull. Right! The experienced stitch-n-glue builders probably work to that tolerance, but I’m apprehensive about making a trimming error. I got to within 1/2 inch on average.

That is, apply enough epoxy to wet the cloth, make it turn from white to transparent, enough to make it adhere, but not so much as to flood it, create runs and puddles. So  … the instructions say to mix up 8 ounces of epoxy (that’s a cup for you folks who cook), and I’m thinking “Oh honey, that won’t be nearly enough.”

There is actually a very good reason for that mixing suggestion. A cup is about the right amount for the working time needed to spread, smooth, re-spread, squeegee off, the epoxy. Any more than a cup and it will start thickening before it’s all spread. In the end, it took me about 2 1/2 cups. Whether that’s the right amount, I don’t know. Yet, there’s fiberglass stuck to the boat, no runs, and it looks like it was done by someone who knew what they were doing.

Oh yeah … spread drop cloths (trash bags in my case) on the floor under the edges of the boat before your (gloved) epoxy soaked hands get too sticky to handle the drop cloths. (Don’t ask how I came up with this tip.)

Oh yeah … (once more) the reason for trimming to 1/4 inch is to minimize wagging interference from the cloth hanging at the bottom, but more importantly to minimize the amount of epoxy it can absorb.

    I just had a little chuckle, picturing you flapping around the shop with trash bags stuck to your fingers… The boat looks awesome- glassing is intimidating at first, but you’ve done a fine job.

    Thanks Shawn.
    Well, I actually asked a beautiful woman to wander into the shop and spread the plastic bags.

    Looking great Bob! A wooden canoe is firmly pinned to my long term list of projects I’d like to complete someday. You make it look easy! For now, I’ll have to make do with my OT Camper 16. Though I have to admit that every time I read your blog it makes me want to get started on the canoe project.

    Canoes are a lot easier than cabriolet legs Bob. While I admit that a Porringer table isn’t quite my cup of tea, I did enjoy watching you build it and learned quite a bit along the way that can be used on other projects.

    There are so many variations of construction techniques that I’m sure you can find one that you’ll enjoy building … and using.

    You done good! (I hear that phrase around here sometimes, and I like it) :)

    What a wonderful outcome to what I pictured would be a very, very messy job! You managed it like a Pro. Like Bob R., I have always wanted to build one; but I might tackle a 1/4-scale project instead, at some point in the future.

  6. Bob Says:

    Al, you’re going to have to really slim down to paddle that 1/4 scale boat. :)

    Oh my, that might have come out wrong. I’ve never seen a 1/4 scale human and I think Al might not survive the transformation to that scale. No offence intended!

    CLC boats are so much fun to paddle; sanding the epoxy not so much. Makes me want to put mine in the water.

    Slimming down would *really* help — LOL — NO offense interpreted in ANY way, Bob. I must try to do the 1/4 scale model, to try out my skill set.
