I am not sure they would be much cheaper. Your talking big and expensive pieces of aluminum, plus mucho machining time. A 1" sheet for 1 60" x8" board would cost about $300 I bet, that's before you touched it with a machine.


A 1" x 10" by 72" slab is about $400, (that's what it would take to get a 1st gen C2 dagger out of it.), if you're buying it retail. Which who the hell buys anything retail. Probably be cheaper if you're getting it in a 20' stick too, and you'd be able to recoup a small percentage recycling the waste.

I'm curious what the machining would cost, or more importantly how long it would take. If the machine is $100/hr, would it take six hours to do it? I kinda doubt it in a CNC, and that's what it'd take to get it up to the cost of a C2 dagger board.

I like these discussions. Way more than WtheF are we going to do with the Alter Cup.


6 hours is probably reasonable - it all depends on the finish you are after...how many steps the machine needs to make. I had a mold made from two chunks of aluminum for a 5lb lead bulb for r/c sailboats. The mold was about 12 inches long and it took 18 hours of machining for the two halves (I don't think the programmer really approached it correctly though).
