30% is purely my opinion.
But I'm guessing that's the percentage of Harbor Freight products we really like, use on a regular basis and only cuss out once in a while. However the step bit sets are always great, always on sale & the extra few bucks for the Ti Nitride coated set is definitely worth it.
I just got around to the rear brake reservoir & bracket on this panhead.
The Reservoir itself is a cleaned up ebay after market deal for a sportbike.
The bracket was a bit of 1/2" aluminum plate with two holes via the hand drill, step bits, some flap wheel shaping and a polished finish.
The fit is accurate enough that the resi is just sitting in there waiting to be tacked on the underside or maybe a set screw to hold it in place.
Step bits are a friend of mine.
Price them elsewhere, that alone will have you convinced.
