New crystal for old dial indicator.....

[Tozguy]

Good work Brino, kinda inspires me to tackle my old yellowed indicator that was made with old fashioned quality.

 

[brino]

be careful when using cyanoacrylate type adhesives around clear plastic. The off gas when drying will fog many types of clear plastic. Once dry though, I don't think it is a problem.

Thanks for that, I was not aware.
In this case the bezel/crystal was off the indicator for gluing and drying.
So far haven't seen any issues.

The background face looks crooked, is it adjustable?

Align these two points and your tenths indicator should properly line up.

That’s why we call him “Brino the Brave”....

In trying to live up to Franks nickname for me, I had one more go at and rotated the entire face.

The result:


Thanks for the encouragement!

Great Job, Brino! I have 3 or 4 DI's with broken return springs. Right now they have rubber band "bonnets" on them. I hope you'll tackle a job like that soon so I can fix things vicariously thru you!
BTW; There's a tenths indicator on a .001 DI? How does it work?

Nice job. CDI is still in business.

Here's a challenge. A couple of 3" I've had for years.
The one on the left is .0001", the one on the right I can't make out.

Yes, but it indicates tenths of an inch!

It's the smaller dial inset at about the 7 o'clock position of the main face.
It counts one number for each full rotation of the big needle.
The big dial counts up to 0.100 and the the little dial counts the "roll-over".........like a carry the 0.1"

Since this indicator has a 1" full range it helps you to know if you're at 0.387" or 0.487".

HA! I know about the rev counter. I thought SLK001 meant there was a way to measure .0001 with a .001 indicator. My Bad. It wouldn't be the first time that a tool I had been using for years could do more than I thought it could.

E6000 can work as a dial indicator glue. There is also a Pacer Canopy glue that would be very safe for the cyrstals... Pacer 56 Canopy Glue
I would also try Gem Tac. Gem Tac Adhesive You can find both E6000 and Gem Tac at Hobby Lobby ( I think). Menards and HD have E6000 too.

The crystal that you ordered off of eBay, did it come flat or was it curved?
I have another two DTIs that are missing theirs and need to find replacements.
Thanks.

Hi Dan, the one I bought was already curved, so I did NOT need the special press that's shown at that Long-Island Indicator link in post #1 above.
I see the link to the ebay one I bought is still active too (seller "sina_shoper").
