Morse taper M3 down to M2

[hawkeyefxr]

Is there a morse taper adapter to go from an M3 to a M2, yes thats right the wrong way.
I am sure i have seen one of these years ago but can find any mention on the normal places. I know it's not an ideal thing to do but that what i want.

cheers

Would that be Takisawa TAL Lathes. or TAL Manufacturing Solutions Ltd | MACHINE TOOLS WORLD | Machine Tools Industry Update | Machine Tools Manufacturer | CNC machine Manufacturer | Manufacturing Industry | Indian Machine Tools Magazine | Indian Machine Tools Industry | Machine Manufacturer

Both have link to Tal Lathes.

Little Machine Shop has three adapters:


Note that the thing they have in common is that the female side of the adapter is always smaller than the male side. That's a corollary to the rule that if you are turning a vessel, you can never make the inside larger than the outside.

I suppose a skilled machinist could make an adapter with the male side smaller than the female side, but that would necessarily mean that the two tapers would be end-to-end - that is, an adapter with the female side larger than the male side would necessarily be at least twice as long as a single taper alone. That could introduce problems with runout which may be why you don't see that configuration very often.
