Laminating Tiller part 2

[Clyde_Wanderer]

Have now completed the laminating of the new tiller which went very well in my view.
Just for the record, I first coated the mating surfaces with epoxy resin so as to let it soak in, then added Colloidal silica to the remaining mixed epoxy, this thickened it up without weakening it or increasing its bulk, and increases the gap filling properties in the joints.
I had the 8mm strips clamped in the jig for nearly 4 wks before glueing and had no problem forming them after glueing.
Still some fine sanding to be done which brings me to the question of coatings.
1) should I give it a coat of epoxy resin, then sand and varnish? if so what varnish?
Should I wet or dry sand between varnish coats?

2) Should I just varnish it and if so what varnish if different from above?

Are you suggesting just varnishing and not using epoxy or both?
Is this epivanes a two pack?
Thanks.

Really doesn't matter what finish you use. Just make a condom out of canvas for it - then it will only be exposed to the elements while you are sailing and the finish will last for years.

BTW Nice job!

Beautiful job Eamonn. How much would it cost at your hourly rate?
New mast up yet?

Epifanes one pot. Canine's gonads.

3 coats of epoxy 120 paper, 5 coats of Epifanes 240 paper, 1 canvas condom, that'll do nicely.

That's a great looking job, congrats on that. Glad the strips worked OK and I think you did the right thing by using the same wood and not going for contrasting colours - what I've read suggested having two different types of wood can lead to problems later with splitting and delamination.

As for the epoxy + varnish, the wooden boatbuilding sites I've looked at suggest epoxy first followed by UV resistant varnish. There is a post about specifics for this approach at the end of a poll I started which names Wood Impreg 120 and Clear PU 360 UV, but I don't know where to get that in the UK.

When you say epoxy do you mean just epoxy laminating resin? it is SP I have.
Should I sand the resin wet and dry, or dry, before varnishing?
I have decided and bought Epicfannies varnish as I dont have time to search out other types etc.
Thanks all for your advice.

You know that makes sense

I think the stuff they use is thinner than laminating epoxy but you can thin laminating resin by either warming it or adding 10% acetone or methanol or other solvent. In the past when I've thinned using acetone the epoxy cured to a darker colour than the unthinned stuff so you may like to experiment. Also check with your supplier whether the stuff you had is subject to "blushing" because if it is you may need to sand it between coats.

I wouldn't even consider epoxying it. Good conventional varnish - Epifanes for me. When I first took on maintenance of my wooden boat I had was persuaded that epoxy was the stuff for coating - with uv protective varnish over it. However, despite bing reasonably careful about maintaining the varnish, all my epoxy eventually degraded horribly with UV exposure. I refuse to use it as a coating anywhere now. (I stiil think it's great for gluing and laminating.)
