Thread: Hermes and couriers
08/02/2022 19:12:36

Our local Hermes man was born and bred in the village, he is helpful and available for queries but of course he can only be responsible once it has reached him.


Thread: Read the T-shirt

My favourite T shirt was my 1985 Team Bike Bol d’or shirt it eventually succumbed to holes and stains.

Thread: Running a Myford S7 in Reverse

I know it feels safer to cut away from the chuck but it is probably worth practicing disengaging the half nuts which can be done very precisely with a bit of practice, as you have a super 7 you have a clutch to stop the spindle and as screw cutting is usually done at slow spindle speed to give you a decent reaction time it is not as hard as you think to stop the spindle as well if cutting metric threads. I think someone has linked to the Oxtool demo on YouTube of how the threading indicator can be useful even when cutting metric threads.

I imagine that Myford re-engineered the clamping to the two bolt style because the one bolt method had proved to be unsatisfactory on occasion. I think it is probably possible to replace the one bolt clamp with the two bolt version.

I feel confident that I check properly without the recommended contortion, I also crack the door open to indicate that I am about to exit if I have missed anything passing me, a look through the gap for a last check and open the door. As a motorcyclist I would queue split but at a moderate speed and with super caution and observation.


Thread: Non-warping Wood for Base?
06/02/2022 13:58:54

I doubt there is such a thing as non warping wood but once wood has stabilised in a location that the temperature and humidity maintain reasonably constant levels it shouldn’t move much. A veneered man made board is much more likely to have reasonable stability and with some care can be very convincing as a solid board of timber


Thread: Very Best Wishes

The maximus on the lathes archive seems to have the headstock cast with the bed, it is difficult to see if the bearing housing has a separate cap with two bolts or a single bolt to adjust the squeeze of the bearing. You say it has been repaired by welding so is it in a running condition or is the repair not completed? If you can post some pictures it would be helpful to see the problem.

The instinctive answer to the trolley problem is to save the most people but what if the single person was the one who was going to rid the world of cancer or dementia? The more you know of the future value of the decision you make could alter the decision but it is like you only know the quantity of people you could save.

When we no longer have to drive cars ourselves the signage on roads could be dispensed with as it could all be in the database for the navigation system. I sometimes wonder why every junction is different from all others, every aspect of a junction could be fairly rigidly defined and standardised. I know terrain is a factor but we do have the technology to move that around, obviously the roads in more ancient settlements are a difficult area as the modern vehicle requirements are rather different from the pedestrian and horse traffic that defined the original layout. It will be fascinating to see how things develop but unfortunately most of us will probably have checked out from this world before all the problems are sorted out and fusion power comes on line.


Thread: Electricity Supply - Fun with Statistics
05/02/2022 09:35:43

Lucy’s of Oxford used to generate their own electricity using diesel electric generators, they had a 1MW induction furnace to supply the casting shop. As an apprentice we visited their factory for a tour round, the main generating shop was unbelievably noisy with a number of generator sets running, another interesting thing they had was a private ASTA testing station which they used to test switchgear to destruction, this was powered by its own diesel generator. Unfortunately we were unable to witness a test but the damage to the railway sleeper lining to the test chamber bore some major gouges from previous tests. The inspection ports had six inch thick glass in the tiny windows.

The increase of 25p was 1/24th of the basic state pension so today would be £5.70 so it would still buy a pint and a bag of crisps if it had kept pace.


Thread: Installing drill chuck arbor
05/02/2022 09:03:16

A morse taper only needs a light tap to grip enough to drive the drill so I don’t think the taper in the chuck needs too much of a hit to grip firmly, fitting a MT shank drill I would either press down on a piece of wood using the quill or give the drill a light tap with the Barson drift. I usually have a small copper mallet handy now to give the drill a light tap. Once you have run some drills near the capacity of the chuck the drilling pressure will secure the chuck but obviously you initially need the chuck to grip well enough to not slip. It does not need a severe beating to grip well.


Thread: Motor protection
04/02/2022 21:33:56

The overload module can usually be set to reset automatically or manually, the stop button will often operate the reset button on the overload if manual reset is selected. The overload module has a contact wired into the NVR circuit so when an overload occurs it will trip the NVR. Reset may require a few minutes for the heaters and bimetal actuators to cool before the latches can be set again. There should be no need to open the box to reset the overload.

Yes, the full load current FLC is usually stated on the motor info. plate. The overload units usually have a current range of a few amps and an adjuster you set to match the FLC of your motor. The basic control is a box with push buttons and a contactor that has an operating coil that is suitable for your supply, for a single phase unit this will be somewhere in the range 220V to 240V typically. When you have your chosen motor then you will know the overload module required for the contactor box. Ideally the contactor and overload unit should be from the same manufacturer as they will fit together neatly.

Well that is a sensible balanced analysis of the changes. If cyclists and motorists use common courtesy and common sense there should be no problems. I got stitched up by a couple of cyclists once, driving on a B road with good visibility of two cyclists I decided to pass them without slowing too much, there was a small turning to the right which I had not allowed for the cyclists turning in to, one cyclist put his arm out and moved to the middle of the road, the other decided to stay on the left, the road is now completely blocked and I had to brake rather hard, I have to admit that I seriously misjudged that scenario but I feel the cyclist who moved to the middle did not note the speed with which I was approaching and contributed to the creation of a near miss. I fully accept that I should have read the situation better and slowed long before it became an emergency. It raised my heart rate but if I was one of the cyclists I would have needed a change of underwear. I traveled that road daily so I was totally familiar with the turning which has little use as it only goes to 4 houses but the cyclists manœvre was put your arm out and simultaneously move to the middle of the road, had I been the cyclist I would have indicated my intention to turn well before moving to the centre of the road which gives the motorist a bit more of a chance to respond to the situation. I feel it taught me a lesson but I wonder if the cyclist took anything from the event.

I think it was an 80th present from Edward Heath in 1971, it hasn’t changed since. It would have bought a pint and a bag of crisps then.


Thread: Motor protection

**LINK** **LINK**

the two components by IMO would make a starter with NVR function and motor protection overload, you are probably nearer to a Toolstation than you are to a rat these days. IMO are a good quality manufacturer.


This item from WEG is very attractively priced and although WEG are relatively new they are a large company based in Brazil and seem to be generating a good reputation. My personal choice would be the WEG as I feel reasonably comfortable that it would perform satisfactorily and the IMO is the thick end of a hundred quid and may or may not be a better device. The links are examples and you will need to select an overload with the range to cover your motors full load current and adjust to your exact requirement or in the case of the WEG select the unit to suit your motor. The IMO basic unit is for a 240v motor up to 4kW in power and will need the overload selected for your motor current. The WEG unit will need to be a single phase model to suit the motor you have. These are examples of what you are looking for so trawl the internet to see if there is a good deal to be found.

if you have a branch of TLC electrical near you this could be another option, again select a base unit and overload to suit your motor.

Inverter drive supermarket supply WEG Starters with overload fitted at very reasonable prices. A starter will include the NVR so once you have an NVR it is easy to incorporate remote EStop and cutoff switchs once the job is finished.


Thread: 4th dro on a milling machine
04/02/2022 10:05:12

Hi Steve, I don’t know if you considered it but MDRO sell a summing unit that will make the display for Z show the result of moving the knee or the quill, it could be useful sometimes if you wish to move the quill and still know the position of the tool in Z. It does need both encoders to be quadrature type so a bit late now but it may be handy to know for future reference or somebody else contemplating displaying quill movement.
