Just a warning to the Group... This morning I received an e-mail that appeared as if it came from the 7x12MiniLathe group and appeared to be a response to something I posted to this group many months ago. I am including it below so you see what it looked like. (I've altered the link and password to keep the unwary from accidentally opening the payload of this message.) Red flags: 1. The source e-mail address was <ia1bnr@...> and not < [email protected]> 2. The response looks like it might be of interest, but it is completely generic. No specific words that refer to the original message. 3. The use of a file password to open the file. (Now why would this be needed for a legitimate response to the message?) 4. The link points to a .Zip file that contains an Excel Binary file. Warning, Warning Will Robinson! Not the sort of file one would expect for a legitimate response to the original message. Needless to say, I did not open it to see what surprises it contained. If you get such message, I suggest that you do as I did and flush it. I now return you to your regularly scheduled discussion of creating swarf for fun and profit. Best regards, -)------ James --------E-mail Body------------- Re: [7x12MiniLathe] Better Way to Temper Steel Hi again, I have not seen any reaction regarding the documentation I directed you before.

Yeah, I thought so too, right up until the day the oil flashed over. Mind you, I still cook with hot oil. I'm just that more vigilant about paying attention to it. ----------------------------------------

Hi Dick,
Yep, same scales!? I cut one down to fit the Y axis on my mill.? I've read that the stainless-steel rules are a different kettle of fish -- some have resorted to using an abrasive cut-off wheel to cut them down to size.
My main issue with the 3 on my mill is their battery life.? I found that particular DRO version draws more current than more-recent designs, at least when the display is on.? I've got a solution for that but haven't completed it yet.
It's good to hear that your DROs are still working OK.

Mark,
From the picture it appears you are still using your original scales the same as I have. As I remember the scales can be cut to length. I am still using mine with zero issues since soldering in the resistor and I still have a spare on hand but have not needed to use it.

Hi Phil,
Here you go!? The wire connects up to the DRO sensor's ground.? I made sure that there was enough slack in the wire so the joint inside the spade connector doesn't flex and break.? I also used stranded wire because it is more resistant to? bending fatigue.

antenna for picking up electrical noise. I think that's part of the reason that messing around with the DROs could temporarily fix the problem, but it always came back.
I have 3 igaging DROs with aluminum scales, and all 3 of them now are hardwired to the sensor's internal ground -- holes drilled in the end and a screw + spade connector
attached. For me, this was the "final solution" to my EMI problem.
As a result of my experience, when I later bought two igaging DROs to put on my lathe I chose to go with stainless steel scales. Even for them I still had to solder an
additional 1 uF capacitor across Vcc and Ground inside the sensor box.

Mark, could you post a picture of this ground connection you made? I just got through putting three of those on a Smithy Mill/Lathe combo.

I can only elaborate?as far as "They Work", iGaging that is. Don't know anything about the glass scales. The iGaging DROs are as accurate?as I will probably ever?need. And the price is right.
I also have the iGaging scales.? They are easy to install.? ?You can even install them with magnets if you like. They are as accurate is by cheap Harbor freight dial indicator.
But do beware there is more then one kind of iGaging scale.? Some are better quality then others.

Can y'all elaborate on the pros and cons of the glass and igaging scales?

Here's how I did a DRO Pro's on my 7x mill...
May give you some ideas on how I mounted the slides...

I have been running TouchDRO for at least the past 5 years. It is really fantastic and easy to use. I have a Clausing 8520 mill.?
