I am 6' 2'' but I have also set up my machine table based on my height. I can still reach up and use a 3/8" drive air ratchet to tighten/loosen the draw bolt. But I quickly found that to be a PITA. I will lose a couple inches in height, but I do not really see that that will be an issue. Now the 3-4 week wait.

At about 10 am, the mail man, dropped off my new ball bearing ER 32 nut. As I had already checked the run out on 4 of the collets, last night, I reran the test with the new nut. Using the same collets, end mills and the hardened ground dowel pins.

All of the collets had their run out basically cut in half, they are now down in the .0004”-.0005” range., the 3/16” collet with the carbide end mill dropped down from roughly .0015” to 0008”.

I was surprise the ball bearing nut, made that much difference.

I also have to clarify, that I also blew all of the collets out with high pressure air to get rid of any grit, swarf or what-not out of the collet slots.

Oh crap, you just had to brag about the new nut. Suppose that will be next for me too!
