Jacobs taper chuck removal tool

[Toolmaker51]

Very good idea, and safer than drill chuck wedges.
A recent disassembly was particularly difficult, where an unknowledged [and self-proclaimed industrial engineer] affixed the two with green Loctite! Who isn't familiar with self-holding tapers, lol?
Not awful different than gauge blocks, except wring together directly after through cleaning with alcohol or acetone.
