Re: FAST mast building ideas
whoo boy. That is a quick need.
Ask someone to "borrow" their flag pole for a weekend.
Really quick, really dirty?
My 16' flagpole consists of 2X4's glued with Titebond II, I bet that
armed with a power planer you could knock off a longer one in a day.
1. get a fistful of 2X4's
2. cut something resembling 8:1 scarphs to stagger throughout.
3. drill holes on one side for sheet rock screws to pass through.
will pull opposite board in for tight glue line.
4. apply glue, wait
5. plane to desired dimension.
If you live where it is warm, use epoxy if you have it.
If you intend to chuck the piece when done, use titebond. FYI -
flagpole has been on the deck exposed to the elements for two years
with no glue line failure. Albeit, I am not beating to windward in a
race.

candidates. Thanks to all who replied. Jamie, I think I may follow something
along the lines you suggested (I was leaning that way already).
To David: Thanks.. But 10 days? That is longer (by far) than it took to build the
hull so I can't put that much time into the masts. Actually, that isn't really the
issue. The issue is the festival coming up August 2-5 that I have to attend. The
scooners should be nervous. Will explain afterwards hopefully with photos to
the list. Thanks again to all.

I used a cut tree for the mast on my Teal, it worked fine. Actually,
pound for pound, I think wood is stronger 'in the round', versus cut
into lumber.
Go to Bolger2, click on photos. I have a folder there
titled "Chebaccos" showing how I built my Chebacco mast. This method
was suggesed by PCB's when I wrote about making a hollow mast. It can
be made from nominal 2x6 lumber, you have to rip a 1" slice off the
side of 2 boards, then you glue it up. The 1.5" thicknesses, with the
1" slice, give you 4".

I emailed the vehicle licensing dept. of the State of Washington,
asking what the requirements would be for me to register my Old Shoe.
Here is their response:
Good afternoon,
Yes, you will need to register the sailboat even though it's under
16ft, this is because of the motor. If you did not have a motor, then
you would not be required to register the sailboat.
To register your sailboat, you must have all the sale receipts for
the materials that was used to build the vessel. Take these receipts
into any vehicle licensing office to register. The office will have
all the required forms that you will need and also the office will
issue a serial and a WN number. Once you do this, then you will ready
to sail her. There is no inspection required.
Thanks, and happy sailing

Guess each state is different.

I plan to build the 4x4 (actual) mast for my Chebacco by cutting a notch in the corners of scarfed 2x4s. This will add the needed 1/2" and leave a 1x1 hole in the center for wiring. Since all the loads are carried by the outside of the beam, no significant strength or stiffness will be lost.
Above the tabernacle pivot, the square cross-section will be rounded. The taper doesn't start until near the top of the spar (gaff rig) and will be effected by tapering the 2x4's from there to the mast head.
I'm considering hogging out some of the wood from the center to enlarge the center hole and lessen the weight, but ... We'll see.

Subject: [bolger] FAST mast building ideas
All,
I find myself needing to build some 3 1/2 x 3 1/2 by 20' masts QUICKLY.
Anybody got any tips? My first thought was to just glue and screw some 20'
2x4s together but that would only yield 3 1/2 x 3. I have no idea whether this
departure from the specs would be critical. Please, this has to be quick and
dirty so no elaborate suggestions.
Thanks,

Buy wider width and rip them to 2x4. The wider boards tend to come
from better logs as well, with fewer knots, or at least knots that can
be eliminated when ripping down to width. It also takes care of the
round edges of most 2x4s

Where have you found 20' 2x4s? The longest I have found have been
16', though it's not that hard to scarf them for longer lengths.
Just be sure to stagger the scarfs between the two boards
To bring the thickness up to 3 1/2" you can always add a center ply
of 1x4, then plane down the outside slightly to make it the right
dimension.

I just finished my 21' Birdwatcher mast. it is 3.5"X 3.5" with a
taper. constructed of 1X4 fir decking. Working outdoors, this could
be finished in a week. I scarfed 10' and 12' boards and staggered the
scarfs throughout the mast. It is incredibly strong, particulary built
as Bolger described with solid section on the bottom 6' and top 5'.
This week will be the other spars. Looking for clear 16' 2X4 or greater
width that doesn't cost an arm and a leg!

How about gluing up a sandwich of 2x4 - 1x4 - 2x4 giving you a total
of 3 1/2 x 3 3/4. Then, either power-plane (or saw or sand) that 1/4"
off, or leave it be. You'd get extra strength but a bit more weight aloft.
As for whether you can get away with only 3", you probably could 99%
of the time, till that fast-moving squall came through and you didn't
have time to reef . . . Also depends if you get good clear wood with
no knots or weaknesses, or construction grade 2x4s with all their
flaws. In that case, err on the side of extra.
