Hello Gary, sounds like it could have been this chap Link
|Thread: Installing a magnetic DRO on my VM32L|
I purchased my magnetic scales from Mdro about 6 years ago. The stainless steel strip was not self adhesive, the alloy section was supplied with a round rubber seal similar to o ring material. The final part of installation was to fit the stainless strip and seal it top and bottom with the rubber insert, I finished the assembly by sealing the ends of the scale with silicone.
|Thread: Change to the Code of Conduct|
So that’s why ARC have disappeared, understandable from my point of view. If my company advertised on a forum that relied on my revenue for funding while supporting references to back door suppliers I would do the same.
|Thread: Femi Hem Saw 782XL|
Same as Jason, mine came from a uk supplier with a moulded 3 pin plug fitted, just checked and as you would expect the metalwork is earthed.
|Thread: VFD speed control fault|
Hello John, the VFD on board 24 vdc supply normally used to energise digital inputs is rated at 100ma. I would use it with a 78L10 voltage requlator to get the required 10 vdc supply. Regards, Michael
|Thread: Where do you put your chuck key?|
I have the same opinion as John MC, using magnets can magnetise tools, then swarf sticks to them.
Their eBay listings show Liskeard.

It did Baz but didn't post, also Santa's beard and all those unguarded machine drives.
I had a similar problem about a year ago, we also bought a new washing machine. This puller may have been the solution but probably costs as much as 2 or 3 new washing machines !
|Thread: Tom Senior light X Axis power feed|
The notion that my milling machine and lathe behave exactly the same is ridiculous.

I do indeed, generally for finishing cuts.
I have a Senior mill but I have no desire to fit a power feed because for me the mechanical feedback from the machine is invaluable. If I did I would make sure it had a sensitive means of torque limitation.
|Thread: Wow, what a battery|
It might have enough power to light the wick.

It is definitely a small block, you can see it under the baseball cap.

Good point Neil, in pubs I have seen two legged mammals wobble.

You beat me to it Duncan.
Duncan, alternatively if you are not using the alarm relay (a b c) you can change its function with parameter 192. The default setting is 99 = alarm output, if you set it to 0 it will also be a run output, it is a changeover contact so you will not need to invert the signal just connect as required. Michael

Hello Duncan, I have had a look at the manual, the RUN terminal is configurable by parameter 190, the factory default is 0 which gives an output when the drive is running. If you change it to 13 it will output on zero current detection, levels set by parameters 152 and 153 which should give you the output you require without an inverter (I think). It is described on page 150 of the manual I looked at.
The control logic jumper sets the inputs to source or sink. Hope this helps, Michael.

Old Mart, that is exactly what I thought before my purchase of a left hand caliper a while ago. I thought it was the answer but despite being reasonably dextrous with my left hand I don't use it as often as I thought I would.
I am lucky to have a few Mitutoyo instruments all of Japanese origin, a bit pricey at the time but I have never regretted spending a bit more than intended for a quality tool built to last.
I bought a Moore and Wright MW110-15DBL caliper about a year ago with the intention of modifying it for use as a centre scribe. For the princely sum of £24 the quality is surprising good, so much so that I can't take it to the grinder, it's too good. The only minor gripe I have is that the auto off timer is too short.
