TravADial for the SBL13
« on: December 13, 2018, 05:41:19 PM »
Thank you to the member here who rebuilt the old TravADial. He wished not to be named. I am on the final stage of installation. Just mocked up the final bolt up.

The professionally (4GSR) scraped cross slide with new a new screw and nut runs very smoothly and precise. The TAD will be nice complement to it.

All bolted, did a quick check against a certified Mitutoyo dial indicator. I made sure the indicator is squared up to the tool post.

Started with both zeroed, moved apron 0.050, they agreed, another 0.050, spot on within reading error. They seem to agree, close enough for government work.

Nice job Nez.  I like your unique bracket you made for the travel dial.  I don't think I can beat that if I tried. ;)

Ken,

Thank you for the kind words.

The holes I asked you to drill and tap are really the enablers.

God speed on your surgery and recovery

It all looks great, good job! I also have a Trav-A-Dial on my lathe. I think you will wonder how you did any work/projects without it!

Thank you for the compliment.

I really like TDA over a DRO, easier to catch that needle over the flipping numbers when turning or threading to a shoulder.

YES! I totally agree with you! I can’t deal with the dancing numbers either! Watching the needle/pointer for me is MUCH easier to relate to machine travel. IE: with dancing numbers, I have a very hard time coming up on value. With the pointer I can see how much further to go because of the mechanical pointers distance from the value. Hope I made sense out of that LOL.

Saw this thread, sparked my curiosity, looking around found a PDF describing the install and care of this indicator

Interesting:

I just checked the calibration against a Mit 0.0005 test indicator for small movement. Precise enough, it follows the test indicator. More than enough for what I plan to use it.
