I want to pick up a co-ax indicator. Looking in my KBC Tools catalogue I see a Blake listed at $378.00 for basic unit then 201.25 total for all the other 6 feelers Total $579.00!!!!! They also have a KBC house brand with all the feelers included for $178.00. Asian import I am sure. On Flee Bay there is on listed for $48.95 item #230224616916. Another Asian no doubt.

So my question is..Is there that much inheirent difference in accuracy to justify $579.00???? or would I be ok with the cheaper ones for what I do???
I am NOT in the aero-space industry :D

It will last you a lifetime if treated properly, get the blake. If it seems like to much, save your money for awhile and keep using a regular indicator/indicol setup(or something similiar). I don't think anybody "needs" a coax indicator, they are just nice to have.

Funnily enough i just bought one of them there co-ax indicators from that ebay seller, arrived in the mail a few days ago, havn't had a chance to play with it yet *but* i was rather pleased with its fit and finish, its really rather well made considering its an import, all parts are ground finish no burrs, and the casting is perfect, even the box its in is pretty darn well made. and it comes with all the tips.... with that said however, i've not used it yet so cant comment on the accuracy yet, but for $48.95 it might be worth you trying one, unless you find a used blake on ebay.

I'd like to try one also but with a mill/drill it is pretty much pointless. They are long and I'm not sure I'd even have the room under the quill to use it so that means I'd have to loosen the head, let it flop around while I raise it up and down. You might want to rethink the purchase if a mill/drill is what you are working with.

The Shars knock off has worked great for me. I haven't measured its ultimate accuracy, but I got a counterbore within a thou without hardly trying. Certainly goes a lot faster for me than the Indicol I had been using.

It does require a bit of headroom:

Comes with all the different fingers. That one in the pic is the longest. The shortest is about 1" long.

Here's one on ebay now that is reasonable if you can use it. Not sure how much accuracy a guy needs in his backyard shop.

Mine was cheaper:p

Actually what i will never get is i could have bought one of them in this country from linear tools or J&L for 149 which is only 40 cheaper than the blake....yet i can buy one in america and get it shipped here for around 41 total! ill never get it but thank god for reliable international postage!:D

I'll probably have a chance to play with the one i got tommorow and ill report back about its accuracy etc which maybe of help to the OP

If you are thinking about spending that much money on a Blake then get one of these.

http://www.haimer.de/english/taster-universal.php

They indicate in all three axis without having to run the spindle and when it's on zero its bang on centreline.

It's a blake, edgefinder and wiggler all in one.

Watch the video.

They are listed at 225 euro's, about $340 but they do show up on ebay from time to time.

I got one of those cheap Chinese ones about a year ago. Think it was about $50 or so on ebay. Very satisfied with it.

I just got one of these Fowlers at Rutland for $139.95, it's still on sale: (http://rutlandonsale.dirxion.com/02081/Main.asp lower RH corner) and I couldn't be happier. I use it all the time. Great way to put your tail-stock back after a taper too.........


I'm not sure that link worked right, it's on page 9, lower right.................

Ok i really have to admit thats an awesome device! hows your trial one holding upto use? are they as good as they look?

If i were paying out for something like the blake then i would probably go for the taster

I got one of the chinese one's off of ebay. I am surprised at the quality! I am very happy.

I find that ebay prices for chinese stuff is a fraction of what KBC sells the same stuff for.

Hi,

I've owned a Blake for almost 5 years. I don't use it as often as I used to. But it's worth every penny. I started with the cheaper import, but it couldn't be relied on for accuracy under .0005.

I have one from littlemachineshop.com
cat no 2060, $69.95
I'm very happy with it. Even use for setting 4 jaw on the lathe.
Usual disclaimer, just a satisfied customer.

I obtained a Blake fairly cheaply but in need of some TLC, sent it to the Blake factory in the USA and IIRC around $80 all up with recalibration. Really helpful folk to deal with and a class piece of equipment.

Why do you need a coaxial indicator? Unless you are just dead set on getting a coaxial setup you can get a B&S .0005 dial indicator and an Indicol holder much cheaper and it will be more versatile.
