I know what you're saying. When I made this one I could not afford to buy one and probably would not have bought one if I could have afforded it.Thanks Gizno..Sorry i didnt realize the thread was that old till now..I am in the process of looking for a beam now..Have a line on a 6 x6 x 8 but that just seem too small..my only reason for wanting to build over buy is cause the stuff on the market seem cheaply made and slow as snot for the 2ooo+ price tag..The pump i plan on using with the 15 hp is 16gpm on the low pressure side and 4 gpm on the high pressure side..I could get away with a smaller motor but the 15 hp is pretty cheap knock-off motor and has an electric start :thumbsup:
IMO a 6" top is just flat out too small but would probably be ok for a vertical splitter.
