I routed all the spar corners with a 9mm roundover bit this morning. It's the first time I've ever used a router. I was a bit daunted at first because it's a big 5kg Maktec MT360 (made by Makita) machine that I bought on EBay. However, I found that a big, heavy machine with power is quite easy to use as it tends to stabilise itself.

I did a couple of practice runs on some scrap and then ripped into it. Piece of cake, it's a lovely machine and it ate up the Hoop, leaving a great finish. I found the adjustments to be quite user friendly and easy to make 

Now I just have to sand and apply the finish.

The mast ended up 7.4kg. The boom and yard are 2.0kg apiece. The shorter one is the boom.

I've also attached a pic of the foils. The colour in these pics looks very red, but in fact its a port wine colour.

Time for a coffee!
