Bolt Fixtures (3)


Done with the bolt head side

Turn it over and mill the other side
with a 1/4" end mill


Looks good

The parts fit perfectly,
everything is on the the money

Back to the lathe, using a 5-C collet
on the 1" dia shaft


Turning the platen down,
so the parts diameter are even

Done. Both of them.
Very pretty metallic finish

Heat treating the two platens in ENGR414 in a furnace. It's like baking cookies
(482oC or 900oF, for 60 min)
