    This Smart and Brown lathe has a Camlock spindle and can use 5C collets direct in the spindle. Running in reverse is just a matter of pushing the button.

    Very nice - solid design and should be useful.

    Impressive worm gear cutting video

    I came across this video and was impressed by the ingenuity of the setups and methods, including using part of a nearby mountain to index against. He has other videos that I have not investigated...

    Ross -

    Your point about correct installation is a very good one, and one that is very frequently ignored, with bad results. I have seen people install seals by tapping around their periphery with...
  5. This certainly could be the explanation, but I...

    This certainly could be the explanation, but I doubt that the orientation in this case matters a great deal. The seals are on a pair of inner gear box covers on the gear selection shafts. These...
  6. I vaguely remember those seals and I have a...

    I vaguely remember those seals and I have a feeling that mine were the same way round. I didn't replace them because they seemed still flexible. Most of the bearings and seals on this mill are...

    For readers who are not in the UK, a bit of explanation might be required re temperatures. Despite us being in May, the overnight temperatures in a lot of UK have often been below 0C until recently....

    Mike -

    I'm not sure what could have turned the red paint black. Possibly they used an oil with some kind of additive that has stained the paint? Just simple straight 'hydraulic' oil without any...

    The photo of the Krupp ingot reminded me of a story I read about one of the exhibitions. Apparently Krupp was challenged to show that the ingot was actually cast steel and not just a large cast iron...

    Mike -

    It may be that you have the multi-lingual parts book with all the numbers, but if not:
    The Freewheel assembly complete (Freilauf, Vollst) is part number 159 1507
    The Freewheel clutch...

    I agree - that sounds about right, even if it isn't Engler 5 viscosity. There isn't anything in the feed gearbox that will come to serious harm with any of a very wide range of oils - It just needs...

    I think the rapids clutch must be good because it engages and provides a solid rapid. There is an internal over-running clutch as well as the electromagnetic clutch. The over-running clutch is a...

    Mike -

    You are absolutely positive that you have the motor rotation correct? The only way to check this properly is to take off the big Aluminium cover on the back of the mill and check that the...

    Mike -

    A bit of history might help to work out what has gone wrong.

    How long have you had the Thiel?
    Did the feeds work correctly before on X,Y and Z?
    Have you done any maintenance work on...

    The doubler circuit looks plausible for an easy modification of an inverter. I took a quick look at the manuals for a few of the inverters that I have used. Most do not give any circuit information...

    I really don't remember the way in which this is done, but I do recall that it isn't at all complicated, certainly not an additional buck-converter; that would involve a number of new components. My...

    Single Voltage motors are fairly common here. These have the star point connection buried in the windings. To convert them from 415V to 230V delta connection, you need to open the windings (in the...

    They also sell 230V single phase input, 415V 3 phase output VFDs (no transformer) here as well. I'm not suggesting they are a good idea, but they are available and can make powering a machine with a...

    Dinky -

    Just for clarity, is your VFD one of those that have been 'modified' by a UK supplier so that it takes an input of 230V AC and gives you 415C AC (or thereabouts)output?

    Yes - agree. The core of the problem is confusion between 'metric threads' meaning just bolts with a metric pitch and a system of standard fasteners (such as ISO). ISO fasteners use metric pitches...

    To answer the original question; the only application for that thread is an attempt to subvert a very well defined set of standards for fasteners with a special that is only easily obtainable from...
