RE: [atlas_craftsman] Re: Dial Test Indicator Question

Harry,

I once sent in my Starrett DTI in for repair. It cost me as much as a new
low cost DTI and they did a poor job. I didn't figure this out until many
months later so did not attempt to return it. I have taken apart a few DTIs
and they tend to be simple. Just work on a white sheet to catch all of those
tiny parts. Note the position of all springs before they are removed.

In general, if something doesn't work, I don't hesitate to take it apart.
Nothing to lose and a lot to gain. At the very least you learn something.
Maybe you even fix it.

Rick

No, Rick. I bought it brand new. I also have one that is broken, and I
think it may be because the setting was too tight, and I overloaded it. I
didn't want to destroy another one. I don's suppose it is repairable?

Mine has a hollow point set screw at the pivot. It is also possible that the mechanism is full of gunge. By any chance did someone use WD-40 to lubricate it?

[atlas_craftsman] Dial Test Indicator Question

Is there a friction adjustment on my Dial Test Indicator lever arm?

Mine seems to be overly tight, and I do not want to damage the mechanism inside. There were no instructions with it.

[7x10minilathe] Re: Dial Indicater/Dial Test Indicator set & Laser tachometer

The easiest way to do that is to replace the motor pulley with a smaller one. IIRC, there was some recent discussion, complete with SDP part numbers on the 7x12 group.
