>RebelCat 5 Update 7-29-09
July 29, 2009 -
Preparations - Ben in Canada asked what he could
be doing to prepare for the arrival of his DVD. I suggested
that he clear an area to work, get his tools together,
and buy the wood. Try to work only with DRY,
STRAIGHT wood - wet wood often warps and shrinks. I bought
the wood for RebelCat 5 at least a month prior to building with
it. I returned some wood for replacements when it warped.
So here is a list of the main wood pieces you
will need, whether you make the standard or extended version.
Buy this wood and let it dry completely, or buy kiln-dried
wood. Think 'straight'.
2 x 6 - 4 pieces 8'; 1 pc 6' (ends cannot have
2 x 4 - 2 pcs 6'; 1 pc 12' - total 24' (or 4 pcs 6' or 2 pcs
2 x 2 - 1 pc 10'

Note: A new design for both rudder and
centerboard will be added here in early October '09, so you may
want to wait before buying the 3/4" plywood. They are already
completed, but I test everything before passing it along.
Testing set for Sept. 25 through Oct 6, '09. New design is oak
plank and sheet aluminum.
If you opt for a wooden mast, be sure it is
solid, dry and straight. You can make your own mast from a 4 x
4, which is free of knots and splits, by using a plane or
electric planer to round the corners and taper it. Look at the
circles on the end and try to get the center of the tree. Or go
high-class and laminate hardwood planks, then plane that down.
Another system is to make a hollow 'box' mast from four or more
Read FAQ 15 and think about the kind of cat you
want, how many people it will carry, cargo, etc. Study the
Flotation Chart to see how you will get the amount of flotation
you need for the weight you will have. The standard RebelCat 5
weighs about 180 lbs, the extended version 250 lbs, both made
from 10" diameter pipe.
Look around for PVC pipe in 10" and 12" sizes.
You want PIP grade, thinwall, drain and sewer pipe, not
schedule 40. Prices vary, so check around. Look for traffic
cones with 10" diameter opening at the bottom. Don't buy either
until you see the video, just locate things. -MA
