Default Taper questions...

Buy a dead center, or a live center, and use it as a gage.
Something with no dings, and a good surface finish.


Hmm... yikes! McMaster has 'em for $50 each...

Don't turn something to some ethereal
diameter and taper, than bore the spindle, using it as a gage.
You could end up with something that is totally worthless.


Yeah, I'll have a taper that works, and vaguely resembles a MT#2 or
whatever, but will it work with any other? Probably not..

Centers are hardened and ground, usually to the right angle,
so would serve as a good gage for setting the angle that you bore.


....Mount the Dremel on the toolpost?... ;-)

Careful bluing and checking could yield a
very good angle if you have something that is right to begin with. .
That's critical to a good outcome.


Yep, this is how Dave did it.

I'd suggest you stick with a #2 taper, no larger for that diameter
stock.
It all depends on the size of the threaded spindle I assume you'll be
making. Even that might be too large. A #3 is probably totally
unreasonable. You don't want the threaded portion of your spindle to
bend, do you?


I was thinking of a 3/4" dia. spindle, but aside from drawing new cone
pulley pattern plans (something that's on hold until the wood lathe can turn
some stock, which is on hold while the basement is cleaned up. . .), yeah I
could use the 1 or 1 1/8" stock. Mind you those will need cleaning up as
the 1" bar is rusty and the 1 1/8" bar, well that might be okay but if it
has to be mounted between centers, chances are I'll have to machine off some
slop to get it concentric first.

I'd have to redraw the pulley because the smallest step is 2" o.d. Come to
think of it, I'll probably have to make a similar change in the headstock
too, as the top surface is drawn at 1 1/2" wide...
