I have found that my cheap PA caliper eats batteries, even when turned off. My Mitutoyo doesn't. Could be that all cheap ones don't but info i found on the web suggests that most cheaper calipers use power even when turned off, hence a dead battery when you need to measure something.
This post reminded me as to how much I hate my current mag base.
So I ordered this https://www.kbctools.ca/itemdetail/1-457-910F yesterday and it was shipped FedEx today. Will let you know how the DI pans out. Can't be any worse than my BB DI which works fine for me.
BTB- Looking through Amazon.ca the Noga standard MB can be had for $160, as to whether it's an actual Noga is another story.
I find the iGaging measurement instruments good. I have two calipers, one blue tooth, a digital height gauge and a digital depth gauge. One thing the iGaging does it shows imperial fractions like 1/32, or decimal inches/mm. I take the battery out of the height and depth gauges when I put them away. They seem to be good quality not super expensive. The blue tooth caliper was under $100 - mitutoyo wants $560 for just the bluetooth adapter - you still need calipers to put them on.
Oooops..... a little bigger than I expected... Maybe could have the next size smaller?
Gotta love KBC's shipping, ordered on the 12th arrived on the 16th. Now to figure out how to mount the DI on it. That detail is not obvious to me.. So far I haven't been able to mount my Accusize TDI via it's dove tail
Hmmm.... much head scratching here.....
How are supposed to mount the DI on the Noga instrument head???? The instructions state it takes a back lug mount?
I discovered that the stem of the DI fits the larger hole in the Noga instrument head... so that works out fine.
Man you couldn't pull this off with a cheapo mag base.
So far I tested the DI against my lath cross slide dial (which I trust) and it tracked really well. As good as my BB DI in any event. Here I'm testing against my Mill DRO and things look good in the X-Axis but suspicious in the Y-Axis?
Checked my X, Y, Z mill DROs again and everything looks good. I love how flexible this Noga MB is. I'd say I'm satisfied with my purchase.
Hmmmm.... the Noga is supposed to take a 1/4" dove tail and my Accusize TDI measures 0.235... should fit???
I never realized that those two dial fingers on a DI are movable reference markers until today LOL
In addition to the aforementioned adapter, you can also make your own post backs for indicators. There’s nothing special about them, the only fussy part is getting the holes right but even that’s easy if you use the existing back as a pattern. Make the post whatever size you need to fit the attachment. Not better or worse, just gives a different attitude for positioning the indicator.
I clamp my dial on the stem too. Easy does it, just enough to hold it. Actually I put a plain back on my dial just to get the lug out of the way & find I don't use the lug much anymore anyways. Kind of depends on your tooling. I also machined a post back like Francist. Pay attention to the screws. Ideally use the ones you have but sometimes not possible. On a brand name they will reference (typically M#) in catalog but on clones anything goes. Your DTI should fit the dovetail but there is another maybe-yes maybe-no. There are a few dovetail standards apparently. 0.236 is a whole lot like 6mm. One of the others I looked up, maybe Starrett but dont hold me to it, was different.
