Machining a Morse Taper in the Gingery Lathe Spindle

<< < (2/4) > >>

vtsteam:
Don't worry, Sea.Dog. I think 40,000 to 70,000 PSI tensile will handle it.

vtsteam:
Boring the taper with a simple homemade boring bar -- similar actually to a D-bit.

vtsteam:
Using the spur center as a test plug. The center's taper is blued and offered up to the beginning bore taper.

vtsteam:
Hitting a little towards the back of the bore. So adjust the topslide angle to slightly more, in relation to the turning axis.

vtsteam:
Gettin' closer.  :dremel:

Notice this spur center has a cross drilled hole. So it doesn't actually require a knockout bar through the lathe spindle for removal
