Where do I get them, Tried the MFGs website, but cant seem to order from there either.

Thanks

Penn Tool Co. is a Haimer distributor -- they should carry the probes.

Did you crash the sensor?

Yes, I crashed the probe... but looks like the probe tip is replaceable and designed to break before the sensor gets damages...at least that is what I'm hoping for

That's correct Mike. You can buy the Haimer without probes. There are several different styles/lengths you can buy. Penn Tool has them...

We break them all the time.Well I don`t personally but order and pay for them.
Had words with them about the cost.Haimer on line had them for about 17 or $26 but wouldn`t sell them,pointing me at a distributor instead where they were about 25 or $38.
I thought there were only two styles of probe,long or short.

I'm not sure if the probes for the Haimer Centro are the same. Probably only the straight probes? The UK distributor prices are close to a rip-off in my opinion. Straight 1:1 conversion from Euro to GBP and yes, Haimer will not sell direct into UK.

My mistake - had a look and the probes for the Centro and the Taster are different.

Don't know where you are located but I have bought several from this company (http://www.transconn.com/). No affiliation and I don't know how I got hooked up with them but their prices and service were always good. I usually buy a few at a time of the longs and shorts because someone:o has a habit of giving the axis a quick turn in the wrong direction.

If a Taster probe is hit hard enough to bend or break it, I'd be wary of relying on the Taster without checking it pretty well first.

Note that a Taster is only calibrated to 0.01mm (~0.0004") but good results are very possible by interpolation (1/4 a division = 0.0004/4" = 0.0001") which is pretty good.

The crucial thing is to be very careful and use at least a 0.01mm indicator to centre the Taster probe axis to the mill spindle.

To be certain, this needs to be done every time the Taster is mounted in the machine spindle/collet.

Note that if using with DRO's that DRO's have and accuracy toloerance of +/- 0.005mm (5 micron) ~ 0.0002" (2 tenths) at best so quite an error can occur if these tolerances are additive.

Tormach sells Haimer Tasters and has spare probes. http://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=HAIMER_TIPS

A taster is suppose to be mounted and centered permanently in a good quality tool holder and if done that way it isn't necessary to check the accuracy every time.

If you are putting it in a standard collet then yes you would have to center it.

Tiffie, That H & F place is charging more than twice what I paid for mine ($318.00 CND tax Inc.). Is everything that expensive there.

Loose Nut is 100% correct about permanently mounting them in a dedicated tool holder.

I used to get a magazine from Australia. These poor guys are taking a severe shafting from their tool suppliers. I thought KBC in Canaduh was bad untill I found out what the average prices were in Australia. I once cross checked a supplier over there against what Sherline charges here. Somebody is making a pot full of money in Oz. Especialy so with that Hare & Forbes? tool suppler.

At least for the mining industry, Australian wages parallel Canadian wages almost dollar for dollar when the exchange rate is factored in.

The Taster probe has a moulded plastic mid section designed to break before damage occurs to the instrument.

I don`t bother truing them up.Time spent doing that wastes any time saving the Taster might give you.I just turn the spindle as I go so that the probe is always contacting in the same direction.Even more accurate than truing it up.

I don't understand how mounting it in a good quality toolholder makes any difference, with regard to concentricity, than mounting it in a good quality collet?

You have to adjust the Taster so that it is lined up concentrically with the center line of the spindle for maximum accuracy. There are X-Y adjustment screws built into the top of the two-part body that do this in conjunction with a VERY accurate indicator.

Once this is done, if it is mounted permanently on a tool holder, it will maintain it's accuracy when removed and replaced in the spindle of a mill. This is only good for one mill at a time. If it is placed in a different mill the alignment adjustment have to be redone for that one.

Obviously if the fit up between the tool holder and the spindle (IE: sloppy fit on a cheap mill) isn't very good then the repeatability (.0004") won't be very good either. On a good quality mill the repeatable accuracy wouldn't come into question.

For most home shop work the repeatably would be good enough even with lesser quality equipment. The beauty of a Taster isn't just the accuracy, you can get many Indicators of good quality, but that it makes setup quick and easy and eliminates a lot of steps that might introduce errors. The level of accuracy needed determines if a 3D Taster is necessary. They are also tool porn and those of us with the tool addiction :( will want one anyway.

Don't forget that to use these properly a DRO is pretty much a necessity so add that into the price if you don't already have one.

That mob charge like scrub bulls as there is little competition... But in general everything over here is more expensive then elsewhere in the world, as such online shopping is fairly popular in Au...

Hare and Forbes == Arc Euro in the UK == Enco in the US.

Ironic that the H&F prices are higher than in the US, since the Chinese ship has to pass by Australia on the way to the US :)

Have you got a link to them on Arc Euro,please?

Not really, minimum wage here is $16 an hour or something like that.... In the US it is $8 isn't it?

That is why we love flat USPS rate boxes... :)
