Hi gough,
The crank 2s comes prest. It is adjustable but you have to take it apart as you suggested. I am hoping the preset will be suffcient without mucking around with it, and if a little too wide I can always put it through twice. with a drill this is no big deal. The extra $$ for one that adjusts more easily just isn't worth it IMHO. I wonder how many people regularly adjust their valley mill or barley crusher?? I would see that I might need to adjust it once - but that would be it
Below are detailed instructions that come with it for adjusting. To quote the paperwork:
"this mill is designed with a gap that can be set as the mill wears or for different crush characteristics. To set the gap you need feeler gauges and some means of pressing the bushings out of the frame. The best way to press the bushings out would be a vice with protected jaws and 2 sockets of the correct size, one that is appropriate OD of the bushing to press against the bushing, and a second that is larger to press the bushing into the vice. make sure you mark the radial location of the bushings b4 you press them out and that you loosen the setscrews b4 attempting to press out the bushings. Once they are out you can rotate them to make the gap wider or narrower, partially press them back in and trial assemble your mill on the bench to check the gap. adjust as necessary. then reassemble and tighten."
