Use a table ban saw to hack off the 340 piston crown .

Your not kidding? I already bought me a precision Chinese hack saw...just vise it in and bring down the blade. I need to get back home and do the measuring. Got me a set of trw L2405f...forged stock. I need the 4" crank now and will get the measurents...money and time....thanks for being on standby. Sincerely jj
