Arnie, you lost me on this one. IMO Parallel has the advantage all over tapered shafts. In my 23 years of building clubs I have yet to dimple a shaft to help with it's bonding. As to the time required to ream a tapered hosel to parallel is quite a bit less time required that to use a SS brush to clean out the tapered hosel and to make sure that you don't leave some small bit of the old epoxy. In fact I've had more Tapered Shafted heads come apart besauce of this one item. I require a lot less shafts in stock, lot less time required in assembly, I can freq match any shaft to the rest of the set, plus I'm not locked into buying the shaft from the OEM at some out of this world price there by passing on to my customer the huge savings and better, safer workmanship. Plus I can better spine a paralleled shaft over the taper tipped shaft. Plus remember you can easly remove the material from "ANY" tapered tipped head in one pass of a reamer, .015/ per side (.03125 per hole)
Just remember this one rule when reaming out a hole, half the spindle speed, around 150 rpm's to 225 rpm's works best, and twice the spindle feed as to when drilling a hole in a piece of SS. Now to all of you clubmakers that purchased them very cheap drillpress's who's lowest rpm is 650 rpm, don't even attempt to ream out a SS head, carbon forged heads will be OK, but never SS.
SS should be drilled at around 35 to 40 sfpm, .375 ( reamer size) X PI = 1.167 = 411 RPM for drilling @ 40 sfpm. 1/2 the drill RPM = 206 RPM for reaming.

Arnie, would you get to the point? : )

Parallel advantages: Parallel disadvantages:

Parallel advantages are disadvantages of taper tip shafts and Parallel disadvantages
are advantages of taper tip.OEMs use taper tip for economy of assembly (time/labor).
You do not have a choice (I've not seen taper tip component heads) and converting taper to parallel requires reaming the hosel. More time/labor wasted. Conversion of parallel to taper tip is not feasible.
Next question?
