Thread: UK or chinese source for ER20 collet nut "hook/c" spanner
28/08/2017 20:36:36

I thought ER20 chucks were spanner flats not notched.

Thread: Linisher cuts out, what to do...?

Remember that you want a motor rated MCB fitted.

26/08/2017 22:16:08

Sorry, just reread my post above, should of course read "13amp" not 24.

26/08/2017 21:00:32

An approximate inrush current for that size motor would be 40 odd amperes so I'm not surprised that the little 24amp fuse keeps blowing.

A proper overload and mcb need fitting.

Mind you, it could have a faulty starting capacitor and we're all barking up the wrong tree.

Thread: Chinese Electric Cars
22/08/2017 20:43:35

I see in the newspaper today the electrical suppliers are saying that the average UK household will be unable to recharge an electric car in a reasonable time because the main fuse is undersized.

Or, you can charge it but not boil a kettle or heat water at the same time.

Russ B, industrial heat exchangers such as air conditioner coils use aluminium fins over copper tube.

Their process however uses thin wall tube, the fins are positioned and then a ball bearing, eg, is pushed down the tube to make it slightly oversize and thereby grip the fins.

Thread: What Material for 5C collet Rack
20/08/2017 16:08:53

I have a range of ER25 collets which I store in an ice-cube tray.

I then screwed it to the wall with a wedge to kick the bottom out.

Brian Ess - That was the AAIB's verdict. There are some interesting variations on possible causes discussed on a couple of threads on the Professional Pilot's Rumour Network - www.pprune.org. That notwithstanding, be it incompetence or technical failure, the results are best avoidedsad

Wholeheartedly agree with you.

As pointed out above, the Liberal party have nothing to do with this - but don't let that upset your prejudices!!

Having, as a professional, had to deal with the results of aircraft 'failures', the dictum of "Safety is no accident" sits much better with me than the "Oh, Boo Hoo, some nasty person has stopped my toys being allowed out to keep me amused for ten minutes"angry 2 Has the memory of the Shoreham Hunter carnage really faded that quickly?

Some VERY odd values around!

I thought Shoreham was due to pilot error not mechanical failure.

Have you tried Wiseman Threading Tools, **LINK**

They offer a "specials" service.

One feature that a smart meter provides to the supplier is the ability to disconnect the supply remotely (avoiding the need to gain access to the property). Just like with direct debits one has to trust that the institution will play by the rules, but it is possible to end up in a weak position if things go wrong e.g. following a malware attack.

Edited By Andrew Entwistle on 04/08/2017 21:23:02

Any evidence to support this assertion? As far as I've seen so far they simply measure the voltage and current. If they also had to incorporate a 200-300A contactor, that would be a different beast.

Lots of opinions and half truths as ever.

Take a look at a few manuals if you want to understand what they do rather than ignorantly opining about them.

Murray

Checked out a Smart Meter manual as you requested and it states..

(Quote)

Contactor Disconnect

The main 100A contactor can be  disconnected locally or remotely by the Utility.

This can be driven directly or driven by the meter at load limiting thresholds

(endquote)

Whose half truth ?

The boilers not theirs but the speed governor looks like a Wilesco model.

Thread: Is Knurling a health hazard?
31/07/2017 23:23:02

This type of thread always gets a thumbs up from me, you begin to realise the vast and diverse knowledge base that we have contact with now-a-days within a relatively small family of like minded people.

If I can add my little towards skin care, a few years back my wife started getting cracked skin on her hands, very similar to 'old Harry's 'ands' from years gone by. This we found was due to a preservative in hand washes and hand creams, also shampoo and cosmetics.

The product is called methylisothiazolinone , see **LINK** for more info. Since we removed this from our house and usage both of us had improved skin conditions.

So correct me if I'm wrong .... the brass tab connectors on the motor are to be left in the configuration they're in just now . Sorry for being dumb 😁

Sean

If you look inside the terminal lid there should be a picture/graphic showing the link settings for star and delta.

Slightly off topic but having looked at the OP link to GROUNDFLATSTOCK.COM they have useful heat treatment data sheets for all of the products.

Thread: Motor rotation
29/07/2017 17:37:39

Agreed, it is a three phase motor, it can be run on 230v single phase but will probably overheat, as you have found.

The single phase method is called the Steinmetz method. Our friend Google will find quite a few useful results.
