Ahhh I thought someone had one on here - yours would be the third one I've seen in nz along with one other parts saw... One got sold on tm a while back, if it was cheaper I would have got it out of curiosity!
I don't have that issue for sharpening, I built a doohickey to tension the chain with the powerhead off the bar. Fitting it up basically saves enough time by not working around the powerhead that it's worth doing.
