Tool Coaxial indicator

[140mower]

As I read your comment I see myself setting up my little gravity experiment and then suddenly realizing how stupid the whole thought was.

....... You didn't climb up on the barn roof with a bedsheet for a parachute again did you?

2) but to indicate, the driveshaft has to be rotating & the body held in position with the side rod, so not sure how that would occur being held in TS?

I’m not sure I follow the comment. Granted I usually use some sort of mag base dial indicator for dialing in a part in a 4J on the lathe - several options to choose from, depending on obstacles / access. The co-ax is just another indicator.

Attached here is what I was trying to describe, the drive shaft is stationary in the tailstock chuck, the part held by the headstock (4J) is what is rotating. Works great.

Where were you when I needed to be rescued! I could used that to pretend I knew what I was talking about all along. Sadly, I wasn't.

Strictly speaking, anything I have to say on this matter should be ignored or deleted since my contributions to date have already proven to be irrational and stupid.

That said, I don't see the point of using a coax indicator if the COAX part isn't turning. Any indicator would do. I'd have realized that myself if I had only thought about it a bit instead of getting sucked into @PeterT's gravity well. If it were not so relevant, it might be better to just call it the proverbial overweight rabbit hole.

But ya, if you don't own any other indicators with long rods, it could be used that way.

Again, this coming from a stupid overweight rabbit stuck head down in a cold dark rabbit hole with a non functional parachute tied to my back.

That's okay.......

The front tires were getting bald........ Then I thought I should do something about the cause, so I decided to take the massively oversized front coil springs I put in a few years back....... Seemed like a good time to swap the leaking steering box out, and since it was going to be out of commission for a while, why not tackle the lifter issue, which became a head swap... I have now reached the point where I am seriously afraid for my life, because if I ever get down this hole and actually confront this rabbit, I think he's going to be a big mofo......
And we wonder why I can't stay on topic what's your excuse?

Old age brain rot. I don't need any other excuses after laying that dead dog on the table......

Are you referring to this particular thread, or your posts in general?

Might wanna check your crank also… Those yellow pistons have an odd firing order with 4 up and 2 down… Don’t think they will handle any boost either lol.
