Guys
lets think about this for a second.
sure it SOUNDS overpriced. but there is nothing that will simplify making headers more than this would. Why? because each section is a precut size, each section lets you measure or count the number of blocks to easily figure out how much tubing you need. each second has alignment tabs, and specific angles that will ensure that if you cut the metal to that size, it will look exactly the same.
FOR THE PROFESSIONAL, I think spending 2000 on a kit like this would be a worthwhile investment (2000 includes booster packs).
for the average one to 5 time use for a home builder, forget it.
Some people can do this by eye, but ask them how many tubes they've had to cut to get it perfect, or ask them how much material waste they have.
some will lie. and some will tell you "quite a bit, and that's where my cost comes in"
ALSO:
how many times do you want to have to cut a new set of smurf tubing. Sure it costs only a fraction of what this does. but lets say you do A LOT of these. what sounds more cost effective? easier to work with? time saving?
I think I'll go with the ice bloks if i were to do this as a profession, with TIG kit and all.
