My wood came today for making cross stick booms.  This is a few sheets

of 2.5mm 5 ply Finland birch.  I am using this with my 4th and 5th

graders this year as well as selling some myself.  In the past I have

used paint sticks but this will be way better quality.



I cut some into strips for making the booms tonight.  The strips are

11 inches long.  I have found that I can get 120 boomerangs out of

each sheet of 61 X 61 inch wood.  One sheet will just do my students

this year.  So cool!!!  If you have not tried the 2.5 mm 5 ply for

short range cross sticks I can highly recommend it.

Rusty,



Glad you are doing better.  I too have A-fib, but mine is (for now)

easily controlled with medication.  It does not slow me down (still

riding my bike to work everyday).



Best wishes to you.

Steve,

I agree, most people can live a long time with A-Fib; it's not a death sentence. I had it three times before; this is my forth. Still, I do notice I get much more tired, quicker, and can tell the difference right away. At 80, I'll not complain too much. I still think that, "Every day is a good day when you don't wake up dead!"

The 2.5 mm 5 ply booms sound interesting, what are the dimensions, airfoils, finishes? For years, I made 10 inch cross sticks by buying 1" x 6" straight grained clear pine, cutting into 10" lengths, rounding the top and bottom cross cut corners and then slicing into 1/16" thick slices to yield 1/16" thick blades 10" long and 3/4" chord. Sanding between a urethene skate wheel and a 4" diameter x 8" long pneumatic drum made the finished thickness about 1 mm (or about 0.04 inches). Painted tips and a hot glue gun, and wood slats clamped and glued in a custom designed clamping jig both assembled AND added dihedral to the finished boomerangs. With my set-up, I could make 150-200 per day! Most of the time, the wood was free cutoffs from other construction jobs.

Kids love these, don't they?
