DRO!!

[Hukshawn]

Yayyy. Been wanting this kind of a setup for a while. I realize I'm kind of cheating a bit as I hadn't quiet got the hang of the dials. But nuts to that. This world has great cheap electronics!

Turns out the back lash on my cross slide is much more than I had previously believed. Gonna have to look into that.
And sorting out some covers foe the sensors.
Not a bad unit. About .003" accuracy over 6" on the cross slide and I think it said something like .005-6" on the 24". Which is kind of a lot but perfectly fine for anything I'll ever do.
Was a good deal.

Bent a cover out of heavy aluminum duct pipe. Used my uncles aluminum siding press brake. Never used one before. Usually just braze guard covers together from sheet metal. Messy...
The brake was tricky. Definitely a knack to it. But this works. It'll keep the oil off the scale anyways.
Easily removable to access the the stuff underneath.

sure works for me

Where did you buy your DRO? Cost?

I have three of the earlier iGaging scales on my lathe and they hold +/- .001" as checked against digital calipers and/or micrometer. I would expect similar performance for yours.

That's the accuracy over that distance. It's advertised along those lines. Or, my graduated collar dials are that far off.

I bought these at busy bee.

The resolution is lower than I'd prefer, probably about half a second. You gotta dial in pretty slowly not to miss

Question for you, if you don't mind? Does your X axis DRO read the actual amount of material moved? Or do you just do the math in your head?

Thanks for your time!!

What I've been doing is measuring my work piece with a mic, touching off, zeroing, then doing the math on how far I want to go. It's tricky at times and for some reason it hasn't always worked. But I'm still a bit new with the dro. The last project I made with it did turn out really well. I got within .001" which worked great. It was a piece that fit into another. Fit was good and snug.

Ok, so the DRO doesn't automatically deduct the correct amount?

In other words, if you move .001" on the DRO, it actually takes .002" off the material, correct?

Reason why I'm asking is I'd love to find one of these small DRO's that has that calculation built in.

Thanks for your time!

Ahh. Ya, no it doesn't calculate. You gotta math it all up.
