The Laguna plans call for (2) 14ft masts made from (2) 2x4s glued together side-by-side and then tapered shaped from 3" square on the bottom to 1.5" square on the top. While I am certain this mast works great, I had a little time on my hands and wanted to make some hollow masts. Lowes had a pretty knot-free 16' 2x10 for $11.22. That, and a bottle of TiteBond II and I was on my way. The first task is to get the 2x10 (very heavy - green Doug Fir) down to a manageable size. A 2x10 is actually 1.5x9.25, and a sawblade is 1/8 thick, so it is quite easy to rip the 2x10 into (3) equal planks. From there, I need to rip those planks into appropriately sized sticks. I decided to maximize the wood I had, so I ripped the sticks into the widest possible sizes - (1.5-1/8)/2 = 11/16.
