hi all...thanks, yes all parts so far i have made at home as i found the idler gear in steel (bit heavy tho is steel), but could not find the lower gears in anything but nylon, so they made from 6082 t6 alloy to keep things light.
so far they have around 10 runs on them and all is well, and the problem now is the palstic g/box casing is flexing when i use 6s allowing the idler gears to run at an angle to the other gears, so ally g/box is on the todo list but i will buy this as its hard to machine without cnc.
i will be making some more gears if anyone is in need but have no interest in mass production, i ran off both lower cogs (31/36 tooth) as i wanted to keep the 2 speed, pm me if you want cogs and we will talk.
thanks all byee...
urgeoner do it, learn to use a mill its not as hard as it seems...but you need to use the lathe to make cogs too, make it to size on the lathe then cut teeth on the mill.
