axle threads

[1930artdeco]

I bought a spare axle in pieces and one of the shafts has trashed threads about a third of the way in. I had a club member use his axle thread tool to restore what was left of them and ended up with the first picture. Now I can screw an axle nut all the way up to the point and beyond where the cotter pin goes. My question is, is this a good shaft? I have access to a good axle from the same club member. Should keep this one in reserve?

Thanks,

Mike
