    Generally with this sort of repair issue there is significant set-up effort and time involved in getting ready for machining when using general purpose machinery. If its to be possible or...

    Thats conventional VFD wisdom which is getting very outdated unless you have demanding needs.

    Those Eaton variable speed starter units need no configuration for normal duties beyond selecting one...

    Peter

    That system looks great. Time to do some digging to find prices and confirm specifications.

    Slight over travel past zero doesn't really matter as, in the real world, its going to be a...

    Dropping back to the DRO query several posts back I have never regretted paying the modest extra cost for three axes rather than two on my Bridgeport.

    Z-axis on the knee makes it so easy to touch...

    billmac

    We are certainly on the same wavelength here. Given that everything seems to have 'undreds of offset memories it seems so obvious that an output on zero for each axis would be very easy to...

    Tried calling the suppliers with distressingly unproductive results. "Duh. Why would you want to do that?" being a good result! Acu-rite plus the add on box, high end Newall probably and Mitutoyo...

    Hi Bruce

    Being a UK guy I don't really understand the US power systems. But surely if he has 220 volts available its just the same as over here with normal 220 V single phase going to 220 V 3...

    Yep thats the beast. The one in the picture has the setting widget plugged in. Not clear if its included in the quoted price. Excellent deal if it is. Memory says £40-£50 for the widget on top of the...

    As the variable speed transmission is effective and reliable you only really need a VFD to do your single to three phase conversion.

    The Korean Kerrey lathe has no relationship to the UK built Kerry.

    The UK firm was subsumed into the same group as Harrison et al and eventually died as an independent design. For a while it was a...

    Whatever the deal you will be paying for transport whether hidden in the price, explicit delivery charge or having to make your own arrangements.

    I've been down that particular EDM rabbit hole concerning the Chinese consoles. Although all the later multi function ones have the EDM button its hard to tell from the instructions if the...

    The mechanical switch is a good idea which I've seriously considered right up to the point of making first cut drawings. Getting something that works properly every time without...

    In principle building a box is a fall back option provided I can find reasonably priced DRO console with a data port. Lots of them have the case moulded to take one but the general listings don't...

    Thanks for the advice to look at EDM capable systems. I shall go looking when my Google-Fu is fully charged! Not doing well at the moment.

  16. DRO with a Logic Output on Zero. Is there such a thing?

    I'm looking for a DRO with a logic output on zero that could be used to control an electronic feed drive to make it work like a lathe bed stop or Bridgeport style rod operated trips.

    I frequently...

    Solves the off the floor problem.

    But if I had space for something like that I'd already have a machine or "stuff" more than filling it.

    I'm underwhelmed by that device.

    Still gotta get up to 14" from the floor. Which are the harder miles! 36" is barely bench top for me, 14" might be a cupboard shelf or might not.

    Is this a plain ordinary Topaz or Topaz Digital unit?

    Ordinary Topaz with the round connectors can only read Newall spherosyn scales.

    Topaz Digital reads common quadrature scales. Far as I'm...

    Jims

    I like that.

    I guess the tool tip shape is basically a triangle.

    Impressively simple and effective. Drilling the tool carrier hole in the right place for the job in question is a great...

    Although the 18 V Makita I suggested is very much at the lightweight end of tools for the job I'm confident it would do the work and not end up as a boat anchor. Little brother is just fine with 1/2...
