Perform a Budget Engine Honing job at home with a $45 Flex-Hone Dingle Ball/Dingleberry/Bottle Brush Hone. If you are building a budget engine, it might not need an expensive trip to the machine shop. Honing with a ball-style hone, might be all that's need to freshen up the block on your budget engine. You this build, I only had about 0.001" of taper and out of round on the 350 chevy small block. So i planned to just throw a set on fresh piston rings after honing the bores. This hone called for a 500-800 RPM speed, so my Dewalt Cordless Drill was perfect on low speed. With a 500RPM rotational speed, one stroke per minute in the cylinder bore produced the perfect 45 degree crosshatch pattern. I used transmission oil as a lubricant, but a thin engine oil would work just fine, as well as the Flex-Hone Honing Oil. I honed for about 30 seconds on the first bore, and the hone became a little less abrasive as I went along. So i ended up honing the the last cylinder in the engine for nearly a minute. The honing removed less than 0.0005". That's 5 ten-thousandths of an inch, not 5 thousandths. So you don't have to worry about removing too much material. Just follow the instructions, use plenty of oil, and ensure you are using the appropriate bore strokes per minute to get the 45 degree crosshatch. And most importantly, clean the bores and the rest of the engine thoroughly before assembly. Engine honing produces very fine particulate matter that does not play nice with bearing surfaces.
