Posts: 88 | Thanks for sharing your project.
I am about to repaint my Arafura Cadet with Norglass.
How did you apply the topcoats?

Posts: 73 McLaren Vale, SA | Hi Matthew, I tried a couple of types of small rollers, close cell foam and a small nap 4mm "urethane" roller, results were similar and probably as good as you will get using a single pack polyurethane and roller/brush finish [spraying will give a smoother finish] I don't have spray equipment. Both Norglass/International state that prep is 90% of your painting time,yup, your undercoat/primer can't be too smooth as the topcoat will highlight any blemishes. The can states up to 5% painting thinners to help it flow, the website says 3%, I did get some tiny bubbles so maybe mine had a bit too much thinners, plus I had a warm [35C] weekend when topcoating, Hope this helps, Roy. | | | Re: Boat repaint 1770

Posts: 182 Grafton, NSW | Hi Roy,
We have two plywood boats, and on the rear beams the bolts come up from the bottom and the nuts are inside the beam. (Can't have bolt heads on the top of the rear beam because of the traveller track).
Having nuts inside the beam is problematic as the inside ones are almost impossible to hold with a spanner. So I welded nuts onto pieces of square 3mm ss so that the nuts can't turn inside the beam. I also ground the ends of the bolts to a point, so as to make it easy to locate the bolts into the nuts.
The bolts on the rear beam of 1434 had 1" square Aluminium washers under the heads of them, but years of tightening had caused the washers to crush into the timber. (No doubt the holes in the timber are also elongated, like yours.) So I replaced the 1" square Al washers with large rectangular 3mm ss washers, (about 40mm x 75mm) so as to spread the load on the timber, and did them up really tight. I suppose I should fix up the elongated holes like you did, but maybe I won't.
Regards, Greg.
PS If you are having trouble getting you arm stuck in the hatches, try using a lubricant.

Posts: 44 | I was able to get the beam bolts to go though to the top of the beam and still having the traveller track span the width of the beam by carefully routing a small section out of the bottom of the track (harken track) so that the track can sit over the top of the bolt heads. It means that you need to remove the traveller track to tighten the bolts, but it may be a stronger way of mounting the beam. If you do it this way, a piece of SS tube for the bolts to go through between the top and bottom of the alu beam stops the alu beam being crushed when you tighten the bolts.
