Re: Metalllurgy question

I'm not sure that it work hardens like some steel or bronze alloys do when machined, but it does have a fatigue life.

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.

Re: 60° v block

I've considered doing the same and decided the way to go would be to dress a wheel that was wide enough to make a single pass to 30 degrees. I have a sine chuck on my grinder so I would just set the chuck to 30 degrees and all would be good. The relief groove at the bottom of the V would give you ro...

Re: Using 5C collets

While Import 5C collets are as you describe, some manufacturers, (Hardinge for one) "spring" their collets. This means that when relaxed, they are sprung slightly over size so the stock can easily slide through them.

I got rid of all of my Import (Chinese) 5C collets for the reason you describe.

Re: Need advise starting a mothballed car

Just a side note... I have a friend that is still in rehab and was in intensive care for nearly sixty days with burns and skin grafts on over 25% of his upper body, arm, hand, neck, and face, after trying to start a vehicle by pouring gasoline in the carburetor. Something we have probably all done a...
