I have a Moore and Wright 0-1" (0.01") indicator, and am very happy with it.  My view is you get what you pay for when it comes to measuring / precision tools.  Maybe its just me but i couldnt sleep at night knowing my engine was put together relying on a 10quid dial indicator.

another vote for MandW, superb quality kit and do turn up 2nd hand quite frequently. I have a full set of test gauges you could check it with as well Carlos so you would know it's good.

Are you sure yours is 0.010" ? most are 0.001" (25.4 microns) or 0.0001" (2.54 microns)

Yeah, You are right it is 0.001".  I have a metric one that's 0.01. 

 

Haha 0.01" would be useless!

lol yeah pretty much.

[Carlos W]

Wow

 

Thanks to everyone for their time and opinions. 

 

Perhaps I should've provided a bit more information.

 

This is likely to be used for my engine build then either put in a cupboard or sold on. 

 

I need something to check TDC, run out on engine parts etc.

Well then I think AC Dodd has answered your question

What use does a home mechanic have for a dial gauge? Measured wear will require the services of a machine shop to put right and they'll be tooled up to measure accurately. You don't have to take any measurements for cam timing, just have repeatability, that you can check any number of times to eliminate drift in the gauge. Measuring end float to select thrusts is all I can think of.

This is a similar question to why do need a straight edge ?   I get cylinder heads dropped off to me to "straighten" up and I check them only to find 50% are not warped, bent or twisted out of the allowable tolerance but that their straight edge is about as straight as the ideal cross country run for a Mini.... 

 

If you use a DTi that has the sort of float you get with the cheaper gauges you run the risk of not getting the job done correctly

 

Do you not check your discs when you fit them ?  maximum runout 0.006"

I agree

[Ethel]

No, I don't measure disc run out. Again, it's not something I can correct that accurately. I can get an idea by spinning the wheel and feeling and how the brakes operate on the road.

I don't measure disc run out, I know fine well the discs on my daily are warped

How long do you need it for? If it's only a few weeks you could borrow mine

[ukcooper]

If you do get one, make your self a wooden box to keep it in, keep the dirt of and stop it getting damaged and keep the little bits with it.

 

If your only using it once do like Tamworthbay said borrow one or look on the auction's on ebay  for a cheep decent second-hand one.

 

I've got 3 or 4 different types the last engine I did I used a micron (0.0001 of a mm)  type one, next I'll use a cheep Chinese Digi one ebay special.

A micron is 1/1000 or 0.001mm

 

(Note I liked your post except the bit about cheap chinese specials)

Lol, if you buy cheap you will not get the desired results, all you will get is what you see on the gauge and not accuracy, but hey if that keeps you happy then carry on.
