I was woundering if any one has a way to put my design into a cad program, my local metal shop want big money to do that for me. 8"*8" 15 or 16 plate dry cell (if i use one reactor or 2 in 1),(and pending out put of my alt) stagered holes in bottom corners, top corners removed on nuetral, vent holes at top. Also i will blast my plates but should i do this after or before i give them to the shop? Do you recommend blasting both sides? btw im sure when i read my post later i will see all the info i left out lol
