I have a Bartaza Sette 270 that I will be selling, as I now have an Niche Zero that replaced it (well, 2 NZs), one for the City and one for the Cottage; an embarrassment of NZ riches!
My Bartaza Sette 270 does did not grind fine enough, so I had added a shim. I then had to add a second shim. Over time, this was insufficient and I could barely grind fine enough at it finest setting.
So I tried to add a third shim, but when I do, the lower burr (i.e. the stepped adjustment mechanism that also acts as the housing for the lower burr) will not re-install properly. When the lower burr is inserted, it will not rotate to its normal dial facing forward position. Rather the dial ends up facing the rear (backwards). Moreover, with the 3 shims installed, the burr set is at its tightest (burrs touching) at a much higher number than before. I have not tried running the machine like this, as I don’t want to damage the unit.
Would purchasing a new upper burr (cone and housing) solve the problem, and avoid or reduce the number of shims? Fyi the shims ( needed) install in the upper burr cone housing.
Or do I need a new lower burr as well?
Or?
I don’t want to spend too much money on this, or it will cost me more money to repair it than I will receive in resale value.
Thanks for your help and suggestions.
