View Full Version : epoxy on doug fir mast?
10-29-2006, 06:09 PM
Well, I'm just finishing up on my solid doug fir mast for my boat which was laminated out of 5 strips of 3/4", finished dimension at its widest is 3" and it is 11' long. I'm wondering if I should apply a coat of epoxy before varnishing it - probably thinned so I don't spend the next year sanding the epoxy smooth. Any opinions? It's for my Pooduck.

since it is already made...yes..I would epoxy it......
Also I would have made the laminations with an equal number of laminates...

I'd say in the order of preference: CPES, thinned epoxy, and epoxy -- but then the varnish needs a good UV blocker.
What boat and what size sail?
I just finished a DF mast made of 2 2x4x16's glued together with Weldwood, but the 3" diameter only goes up about 4' and then tapers to 2" at the top -- and it seems really heavy to me for my 14' dory. I'm thinking of reducing the diameter to 2" for more of the length, but am not sure...

Thanks, Searover, but 3 coats of epoxy seems like a bit much for a mast on what will be mostly a dry sailed boat - heavy too. The idea is for some protection. I think one coat of thinned epoxy and several coats of varnish (I've been using Schooners on the rest of the boat) will be enough.
I chose 3/4" fir since I don't have a table saw, five lams made the requisite thickness. The mast starts off at 2", becomes 3" at one foot, and tapers to one and a half inches at its top. I found out, today (t is actually a bit less), that I should have cut the slot for the lanyard before I rounded it to make life easier but I think it turned out OK. Mostly I have been resembling a human belt sander lately. I took a 24" belt, cut it, put sticks on the ends, and did the old shoe shine trick up and down the mast. The half mask ventilator was a good thing to have, let me tell you,
Thanks for the replies everyone.
