Re: Has qualtex inmproved on their bosch brushes?
Yep, i always give motor com’s a tickle with a ceramic stick, theyre always that bit quieter when you do so i’ve found.. which must be a good thing 😯
Martin, i would disagree with your point about com sticks only being good for smoothing ‘tramlines’ on commutators, i’m sure you remember the gen Hotpoint armatures which came with a dusting of ceramic powder on the com, no tramlines on a new armature so that can only have been meant to bed in the brushes.. worked too, IMO 😉
