Eric, as a side note- thats a very interesting shaft straightener.
i imagine that it works really well with heat and the applied pressure.
Did you build it?
do you have any other threads related to the little unit?
this far NW, anybody who plants Blue berries here- the bushes never get more than about 3' high.
i will ask what varieties they have here. Our soils are very acidic, around 5 to 5.5 PH, lots of rain, around plus 5c in the winters to max of 25c in the summers
