Better quit now before another "too many tools" penalty flag gets thrown

Bill,

I think you pretty much have it.

This is basically what Russ said if this helps! This is for a 1/32" groove http://img.photobucket.com/albums/v647/Fighter1/PC220891.jpg Other factors in the configuration may be bore size, groove width, depth of groove, distance from face of bore to groove. If you know the bore size, you should...

Bill, Possibly if you carefully do it the way you did with the test indicator in your above post and get it perfectly centered, you could then sweep the bore with the test indicator. If the bore is then concentric, just do as Harold suggested and just indicate the bore next time to center it. That s...

Right you are Harold I'll put a little more thought into it next time as not to confuse others. I always manage to neglect the details as I think/type/post it as if I were doing it and did not connsider the possibility of someone setting up at 45° to the true X,Y axis. I can usually eye it in very c...

Bill, There is no need to center the RT to interpolate a bore such as that. Just bolt the RT to the table, center the part on the RT, plunge and end mill in in a location close to the diameter of the bore you need, and crank the table around one revolution. Once you get around measure the bore and a...

I DO WISH I had a quill stop, though. Is it possible for you to take a picture of the quill stop mechanism and mounting and post it on this thread? Bill, Here is a simple one that was quite a common mod to machines like mine. This is for an indicator to gauge Z travel and is telescopic for adjustme...

I hope you were joking. You can make a profit with nothing more than a lathe and mill. It's not the machines, Glenn, it's the guy twisting the handles. I think you know that, too. Harold Yes, that was a joke! I had a couple of jobs during High School and that's about it as politics seemed to get in...

Harold, I would agree, but there are different points of view to consider as far as "just in case" tool collectors. It appears to me that you did manufacturing type work where quoting was involved. When you quote a job you know exactly what you will need to accomplish the tasks involved an...

Yea...

I'm tooled up to where I can make just about anything but money
