Shopping around for a dial indicator and saw a bunch in ebay for cheap. Are they any good? Or am I going to regret it? I am looking for one to do some transmission work. I am not going to use it too frequently.
A little more information would be helpful. What brand? Used or new? If used, what condition is it in?
How often you use it means nothing if it's not accurate.
Some of the imports are reasonable quality, some are not. I lean toward buying used USA-made old name brands. Take your time and look for a retired machinist that is liquidating his tools. Some import stuff is so poor that it will fail at the first use - it just looks like what it is supposed to be, so "NEW" means nothing. It is still a gamble, but take your time and you usually will do OK.
I have one of the inexpensive dial indicators that I bought with a c-clamp style base for use on aluminum transmission cases. I've used it a few times and it works fine. I have an older one from my grandfather that seems to be built better, but on a couple of measurements I did with both, they were both within about .0001" of each other.
In truth, I was actually buying the base and got the dial indicator with it.
Most of the ones termed "New" does not list a manufacturer. So I am guessing they are imports. Other than that, I see a few used ones that are either Central Universal, Harbor Freight, Shars, etc
i have a machine shop and as for reasonably priced indicators i have found that fowler is a decent tool you can find them at enco.com or msc-1.com just my opinion chris
My experience is that when buying measuring devises, Cheap is not the way to go.
Starrett and Mitutoyo are good, There are others also as mentioned here. I did a quick check on e-bay and found both of these brands listed at very reasonable prices. I would stay away from the $0.99 (with 19.99 s&h) New for 20 bucks would scare me also.
If it was me buying, I tend to think that anyone who would have purchased a starrett or mitutoyo and is now selling it on e-bay; probably took good care of it for they are not cheap.
I have a Starrett which is very precise, however I needed another one and bought an ebay unit with a 2" dial for $15 plus a few bucks shipping. Based on weight and feel it's definately "cheap" but putting it side by side with the Starret and moving my mill's X/Y table to see how they read as compared to each other, only towards the limit of the dial indicators (they're both an inch) did the import one drift "0.001".
For 99% of the work I do, "0.001" is unnecessary because most things I've had to fit, or make, are given a tolerence range anyone, so I actually bought a second one to use with my lathe for setting up the 4-jaw chuck properly. For $15 that saves me digging through the milling machine's drawer and can stand in one place and dig through the lathe's drawer
