What wood for mast core?

I plan on carving a wooden core for a mast on my CNC machine, then covering it with carbon. Anyone have any advice on what kind of wood? I'm thinking poplar.

Re: Building my next mast

I love trimming a carbon/epoxy part. All that lovely dusk to get in your skin.

Re: Building my next mast

You need your carbon running at 45 degrees to prevent twisting, but at 90 degrees (along the mast ) to prevent flexing. It is hard to get a mast stiff enough when going longer in a homebuild, that's where the production masts have the edge. Thanks. I am going to alternate between a high K tow cloth...

Re: Building my next mast

Think you need a bigger board... pretty wood molds though Smaller, actually. I built that one out of an old windsurfer that I broke on a hard landing. And I overbuilt it. Its HEAVY. I am going to build something smaller and MUCH lighter. The molds aren't wood. They are PVC, and covered in finishing...

Building my next mast

I'm prepping the molds for my next mast. This one will be about 84cm. My previous one was about 54cm, and I've pretty much outgrown it. 20180518_200229[1].jpg From what I have gleaned on this forum, the best way to get this stiff is to lay the carbon cloth so the fibers lie at a 45 degree angle. The...

What direction were the fibers? How many layers of what weight cloth?
Outer layers were twill weave but I also threw in a lot of carbon scrap with the fibers going the length of the mast.

Re: How thick can I lay carbon fiber?

I made the carbon skin over my foam core WAY more than 1mm, but I have a very twisty mast.

Re: Against all odds - Ragnarok 2018

I managed to finish 2.2 laps. You really need to get ahead of the pack before the 1st gate. This is what it looks like if you get stuck in the middle and have to wait: RagnarokGate1.jpg Ragnarokgat1.jpg Then you need to pick your course carefully so you don't get into any wind shadows, or get stuck ...
