Re: MIG for Cast Iron + Small Welding Table

Well, I ran into the dude today that I did the weld repair for and it's doing fine.

It was a casting for a machine in a commercial wood working shop. Since the machine was down for a couple of weeks work was backed up and they have been running the tar out of it since it was repaired.

Encouraging...

Re: Metalllurgy question

No, they were kept on dry ice after they were quenched.

I've seen small table top furnaces about the size of a beer mug that are used to re-heat treat the rivets just prior to use.

Re: spot drill angles

Use a 90° for chamfering, a 120° for 118° drills, and a 140° for 135° drills.

Re: 60° v block

I was going to use it to check roundness of of shafts, etc.

A 90 degree V block will not detect tri-lobed shafting.
