Raising the Mast


In our previous installment, I bored a lot of you to death with a windy essay on "plan drift".  You can wake up now.  Anyway a couple pix to detail what I did with the mast and how the stock installation should look.   First, where things stand pretty much right now.

 Well it looks spartan and in a fashion it is.  Since I didn't get the forward thwart to fit as tight as it ought, I will probably remake the part.  Also wound up splitting one of the upper rails.  Still it'll work for now.   That's is not the mast, just some lumber mocked up for a mass for checking vertical.
So, what's going on here?  The stock Teal design uses the thwart as the mast step and a small box with a square hole for the mast partner.  It's designed to go in one place and is meant for the stock sail rig, such as this:

This shows a pretty stock Teal, the handling of the mast step has been handled very nicely (though I notice that's not a spirit rig....).   This picture was liberated from http://www.duckworksmagazine.com/06/gatherings/scuzbums/index.htm  This is  Duckworks magazine blog, which is part of the rest of their site, and store  http://www.duckworksbbs.com/hardware.htm--which is where my epoxy, rope and glass are coming from, so I hope they don't mind this liberty.

The reason I built mine different was because I knew I was going to have decked bow and stern (those glued in frames).  I figured that the mast step rails could go forward and help secure a bowsprit (were I to go the jib route), so could be finished as brightwork, with room for stowing stuff below.  Since I had assembly issues with the first go round, the whole works (not the mast partner though) will be replaced with items of a better fit and finish (matching wood if going the brightwork route).  A couple blocks bridging the rails will retain the mast and partner.  Actually a more complicated than the original design, but now any rig could be hung on the boat (well pert near).  

Oh, and the mast too.  Getting back to the build, it started out as four 1 x 3's from Home Depot (who had 1 x 3s, for the person without the table saw).  Dig out the clamps and Titebond II and away we go.....  The mast is a three plank lamination that comes out to a 10' 8" mast.  The first two planks were held together with screws, but the third plank lamination had to be held with clamps and weights..It would be practical to do this part on a nice chunk of concrete or driveway, so as to avoid any bow in the finished product (I seem to have a 1/2" bend over the length of the mast
A few clamps and a lot of lead (I'm a letterpress printer with a Linotype, so finding weights is not a problem).
 So now I have a 2 1/4" stick.  Don't need all that wood, honestly, and who doesn't like a round mast?  So, a little creative cutting with the circular saw to rough off the corners and back to work with the hand plane--a couple hours later yields results.
If you look at the pencil, you can see the curvature--if all else fails, this will make one hell of a spar for somebody.
The finished product, though the top of the mast needs a finish trim.  The mast has an oval cross section, with the laminate layers running fore and aft.



So here it is, suppose it should be a bit more dashing at this point, but it's pretty boatlike so far.
