well, my sprockets and chain come in. i know that oak will wear out with time thats why i made my adjastment so it will alow me to adjast rollers with wear up to 1". when i was sanding rollers (grid 40) sand paper had a hard time with it and i laninated oak in criss cros patern so grain meets oak at the hardest part of oak grain, i used a "slices of 1*6" not a one solid 6*6.
yea, i didint realized how much work this build will take but iam enjoying it. as far as toleranses go i know that 1/16 is alot so i will get it with in .005 of alighment. i can adjast each side of the rollers independed so i think alighment not gona be a problem.
yes iam exited about being FIRST to make such grain mill, i had many "sleeples" nights trying to desighn and engineer this mill, i used NO BLUEPRINTS i saw it in my head.
i understand your conserns about rollers being soft but there is no way of telling it how long they will last because its newer been done before. worst comes to worst i build couple more rollers and keep them in inventory or i buy a "monster" mill. iam having a blast building "woody 3.0xpr".
build is mooving along nicely i havent made any mistakes and i have to adjast desighn only one time, other than that its exactly what i see in my head.
i still have to make a hopper and finish a drave system for the rollers and motor.
i didin't brew in a while now, cant wait to finish this build and brew some good beer.
also iam working on fermentation chamber i jump on it after this mill is done.
i might finish it tomorrow i post more new pictures!
