cut guide set up

 
I sterted off with out a cut guide thinking I could control the cut ok, which I did for about 12 inches before the cut went inside the line! luckily I have more wood than I need and can flip over after one mistake. The guide can actually be a little rough on the saw but the cost of the saw over the cost of the spar makes it a worthwhile control measure.

Spar thickness cut layout

 
This is how the spar is not set up to cut the tapered thickness (smallest dimension 18ft(l) x 6.5in (w) x 2in (t))
where is tapers from 0.5in at the tips to in the middle. Note the aluminiaaum cut guides clamped on about a quarter of the way in with the saw through the cut. Long hard slog that cut is I can tell you.

0.6 hrs solo yesterday in the Robin. Broken nimbo-stratus between 2500-4000 feet but clear over the coast so did some lazy eights, rolls and steep turns over Stockton beach. Couple of touch and goes
