holes for spaner wrench, should have been slots instead of holes, holes are hard to find:D

Thats the end of the story. I was impressed with the outcome. 0 runout at the collet and .002 6" out. All I have left to do is to make a spaner wrench.

Hi digr Why did you make it in 2 parts and weld together or am I missing something!
Still nice job.

Thanks I didn't like the idea of threading into a blind hole. I guess I could have run in reverse and and thread out but I felt more comfortable making it in two pieces, plus I am a welder not a machinist I just pretend to be one on weekends.:D

Well that qualifies you as both machinist and welder,
Just a dang fine job!

"I didn't like the idea of threading into a blind hole".

Get a 2" travel dial indicator.
Mount it to the bed with a clamp or a magnet.
It makes boring or threading into blind hole not scary at all.
