No, provided the 4x4 is flawless. If it isn't. cut it into 2x4 and
laminate :). Seehttp://www.ace.net.au/schooner/build.htmand click on

Bolger is usually pretty conservative in his spar design - by that I mean
that he doesn't take chances by designing them too skinny. The reasoning is
that most guys will NOT have access to old-growth Sitka spruce or the like.
So his masts (certainly in his more recent designs) are designed to be made
from stuff you can get at the local lumber yard. Of course you should avoid
stuff with huge knots in it, but little ones are OK. Lengthways splits in
the wood also do little harm - The glue will fill them up anyway.
I made the mast of my Chebacco out of reclaimed timber from floor joists -
two at 2.5"x5" and glued them together (epoxy). Despite the fact that there
are a few knots in the wood, and nail holes filled with thickened epoxy, it
has held up well over the past 4 years, with never a sign of failure.
The only danger, as far as I can see, is to inadvertently make the mast
skinnier than the dimensions on the drawings - easily done with power planes
and the like. If anything, leave it a whisker thicker than on the plans and
you should have no worries.

Last mast I built I had to use 2 2x6's just to get enough nice stock in
the center to build a 3 1/4 inch (I think) mast. One huge advantage
going this way is you can slather up the boards with construction grade
glue (like Elmer's orange stuff) and drive sheet rock screws in it
instead of all those C clamps you still dream of owning. Wait a week,
pull the screws and cut off anything that isn't mast.
I've done the final shaping with nothing but a circular saw (8-sided
it) and a block plane. Took 2 hours. Had it taken 3 hours, I would have
had to stop, as the plane was HOT in my hand fromt he friction.

years now, and once you get the Orange places the rest run ascared.
Last mast I built I had to use 2 2x6's just to get enough nice stock in
the center to build a 3 1/4 inch (I think) mast. One huge advantage
going this way is you can slather up the boards with construction grade
glue (like Elmer's orange stuff) and drive sheet rock screws in it
instead of all those C clamps you still dream of owning. Wait a week,
pull the screws and cut off anything that isn't mast.
I've done the final shaping with nothing but a circular saw (8-sided
it) and a block plane. Took 2 hours. Had it taken 3 hours, I would have
had to stop, as the plane was HOT in my hand fromt he friction.
Laminating from smaller pieces a good way to reduce the chances of warping.
It should be cheaper too.

No matter how many times I measure my house, I can't figure out a way
to get a LS hull outside without taking down a wall. Since this seems
like an even worse idea than make her cockpits self-draining, it
doesn't look like I'll be able to do much more with the hull until
the weather warms up.
So it's on to the spars.
Payson calls for a pair of 16 foot 2x4's to make the masts. Is there
any reason a single 4x4 wouldn't do the trick?

No matter how many times I measure my house, I can't figure out a way
to get a LS hull outside without taking down a wall. Since this seems
like an even worse idea than make her cockpits self-draining, it
doesn't look like I'll be able to do much more with the hull until
the weather warms up.
So it's on to the spars.
