I have a NEW general international table saw, and I'm finding it exceeding
difficult to change the blade.

My arbor (not a General) has a large round collar with small round holes
drilled into it radially. Although you could lot these with a straight
rod as a tommy bar, it's very awkward (and chews up the holes). Much
better was to forge a well-fitting C spanner, which locks more easily
and doesn't wobble.
