Re: Woods Skoota 32DM

I found using Quick Fair as a final thin skim coat to fill pinholes etc was a good use of it to save $$.

Most of my fairing was home made mix and it was always a fine balance to getting it right. I should have used a measuring cup and actually used a consistent recipe.

Re: Door material?

Hi, Both cabin and head doors on my 40' cat were 3/8" core Nomex with 200 gm/m2 carbon on each side. In other words very light. They weren't flimsy or distorted. I don't think your 12 oz with distort or be as flimsy as you think. You could always glass a few foam ribs to the inside to stiffen it up ...

Re: Respirator mask during the pandemic?

If rolling and tipping a respirator type half face mask with VOC cartridges is sufficient

if spray painting, the MSDS for the 2 part paints usually says to use positive supplied air. It can really damage your lungs once it is aerosolized.

Re: SOBX Little Big Boat GV15

Hi,

I think you've done the right thing relieving the tightness of the seam to eliminate any hook. Just look at in side view and see what it looks like. Is it a nice smooth curve? If so all good. If the curve looks lumpy then you should adjust a bit.

Re: Chrome pitting

Zamack is a zinc alloy. The chrome plating protects it for a while, but when it breaks down the zinc part of the alloy gets eaten away.

Like brass is an alloy of copper + zinc. In sea water it gradually "dezincifies", with the zinc going away, leaving a pink spongy copper remainder that is very weak.

Re: Woods Skoota 32DM

Mixing foams is OK as long as you sort of keep highly loaded panels the same type of foam. At least for ones that experience significant wave loads like hulls. For cabins and cabin furniture I'd be OK with any sort of mixing of them. A true purist would insist on scarphing the foam at a 3:1 bevel to...

Re: Chrome pitting

Those are pretty ugly pits (I think) from the photos. The odd thing is what looks like chrome plating peeling back from the countersinks?? You're pretty sure they are not zinc with chrome plating? That would be my guess. Scrape the base with a knife. s.s. will be very hard to scrape but zinc, being ...
