New tool eliminates noxious epoxy sanding dust

I think the worst job in building a cedarstrip canoe is dry sanding the epoxy coating on the hull exterior to get a smooth, fair, ripple-free surface in preparation for brushing on spar varnish or spraying 2-part polyurethane clearcoat. So I've switched to wet sanding the epoxy on my hull exteriors ...

Re: Need sail made for 20' sailing canoe

When I acquired the 1931 20' Old Town, it had the usual canvas and cracking paint. I tore off the canvas and weighed it. 22 lb! This battleship's heavy enough without putting 22 lb of canvas and filler back on it, so I'm using 3.9 oz Dacron like Pam Wedd uses on her lightweight cedar/canvas canoes. ...

Re: NewSpring Clamps for Bead and Cove Stripping

Jim, Here's another system of using spring clamps to hold strips together to ensure hairline joints. Harbor Freight sells an immensely strong little spring clamp for under two bucks with serrated rubber ends that really grips the strip below tightly without marring. Couple that with pieces of 1/4" d...

Re: stemless vs ash stem test

I like Jim's idea of having a test to see which bow/stern construction method is stronger, stemless with alternating strip joints, or inner and outer stems of white ash. Jim sailed a canoe off his vehicle at 60 mph and the hull was destroyed but the stem survived intact. That's his entry in the test...

Re: Need sail made for 20' sailing canoe

Jim,
Todd would be my first choice. I've read his book and he lives less than 300 miles from me in Madison, WI. That's driveable, even with a 20' canoe–which I'm making a special trailer for.

Need sail made for 20' sailing canoe

I am setting up a 20' Old Town Guide canoe for sailing. I need a knowledgeable sailor and sail maker to help me find the center of effort for the canoe so I can locate the mast and leeboards, then I need a sail made. I live in northern Wisconsin about three hours north of Madison. Gary gary@canoecra...

Re: Help with Oil-canning

Add a full-length wood keel to give the bottom more longitudinal strength.

Re: How many strips to build a canoe?

I just finished a Prospector and counted the strips. This is a deep canoe (15") so the higher sides require some extra strips. The outside dimension of the hull amidships is 56". My white cedar strips are milled from 7/8" planed boards, a little thicker than most builders use. So that means I use le...

Re: tips for great varnishing

I learned long ago that to get a perfect varnish job, you need to prepare the surface perfectly, use a tack rag, strain the varnish and heat it up to about 120 degrees F. I don't care how well you've vacuumed the sanded surface, there are still tiny particles that only a tack cloth will pick up. If ...

Re: Ash bottoms for tough river?

Keep in mind that graphite is black so absorbs lots on sunshine if left outside overturned on a rack. It has no inherent UV protection so will get very hot in direct sunlight. Epoxy softens at about 150 degrees so the black epoxy/graphite/silica will definitely soften in summer sunshine in southern ...

Re: Keel Screws

I glass over the keel screws to ensure watertightness. I don't use decorative cups for the screws though I now it's traditional with Old Town and other makers. The cups were used by cedar/canvas canoe makers to distribute the force on the screw so they wouldn't pull through if the keel suffered a ca...

Re: Water-based stain under epoxy?

With Jim's advice in mind, I've made up two test panels. One for a trial of water-based stain on white cedar strips, and the second a test of a new epoxy I haven't used before (Clark Craft). I had to make up a test panel anyway for the epoxy so making another for the stain test was no problem. I'll ...

Water-based stain under epoxy?

Has anyone tried to apply fiberglass cloth and epoxy on a cedarstrip hull that has been darkened with water-based stain after final sanding? How did things turn out?

Anyone need 20' long white ash boards for gunwales?

I have access to an exceptional, large-diameter, straight 20' white ash sawbolt that a logger who loves canoes cut for me. It's now at a sawmill in northern Wisconsin near Spooner. We'll soon be cutting the log into 5/4 x 6" boards for gunwales for canoe builders. If anyone has a serious interest in...

Clear coat UV protection: I'm eight years into a non-scientific test on the UV protection of 2-part polyurethane auto clear coat vs spar varnish for epoxy/fibrerglass substrate, and the results are encouraging. I used 1 x 1 cherry strips to glue up a tailgate panel for my utility trailer. I coated t...
