hi, i'm going to build my own mill as a access to a few free parts has come my way, i currently use a converted pasta maker which works well but takes a long time and i have to stand there with a cordless drill to power it.
the mill is going to be either a 2 or 3 roller (4.5 inch by 10 inch) and powered either by a circular saw motor rpm,1800w,240v or a kenwood chef motor.
the kenwood chef would be my prefered option as it has already has an attached gearbox-currently faulty. the problem is if i fix it i've also fixed the problem and swmbo will want her kenwood chef back!, if i use the skillsaw motor it will require a large amount of reduction so i'm thinking it will require a 2 stage stepdown otherwise 1 wheel will be enormous.
any ideas how i work out the sizing to get from 4100rpm to 150 ish in 2 stages?
i'm hoping to source a few parts from old washing mavhines to keep the cost down.
