Hey Allen,
First figure how high you want the primary to be from the platform.I made my
first one only 1/2" off the base and it's hard to get a stick or rag
underneath to clean the dust an stuff.An inch would be easier.If you're
using 1/4" tubing then cut the strips about 1 3/8" wide. For 1/4" spacing
between 1/4" tubing divide the # of strips by 1/4" then stack them on top of
each other at these intervals and tape them together and drill all at one
time.Fur instance, if using  4 supports then divide 1/4 by  4 which equals
1/16".Stack and tape the 4 supports together with the ends "stairstepped"
1/16" from each other.Then mark each hole 1/2" on center 1and1/8" from the
bottom on the support on the top. Drill all the holes 1/4" in diameter then
recut the strips at 1and 3/16" from the bottom lenthwise so the tubing will
snap into the supports.This way you can always unsnap the primary.You can
also just stack all of the strips together evenly and move each strip out
1/16" from each other on the base but remember the last  (first) strip will
need one more hole drilled than the rest because the primary starts and ends
on this strip. Man I just reread this and it's confusing check out my
primary support at http://hot-streamer-dot-com/temp/DSCN0025.JPG  Everyone does
it differently so you should piece together everyone's ideas and incorporate
it into you're own unique style.Oh yea, don't trust my math!
