Thread: Angle grinders - Dangerous or not
19/07/2019 11:05:18
Posted by Kiwi Bloke on 19/07/2019 06:05:48:

Nasty, dangerous and scary machines, but I'll continue to use mine and hope to get away with it. The alternative doesn't bear thinking about.

In Oz & NZ, Jaycar sell a soft starter kit for power tools. I've just bought a second one. I think they are running low on stock. The design was published in Silicon Chip magazine, July 2012. It reduces the start-up kick quite well. The design is, I think, unnecessarily complex. In essence, a NTC thermistor, with a cold resistance of about 20 Ohm, is in series with the load, until it's shorted out after about 0.5 second. Not only is the kick reduced, for the benefit of the operator, but the inrush current is severely limited, which may be helpful in some electrical installations.

Does anyone know of a UK equivalent, preferably one that could be incorporated in the lead?

Although it hasn't happened yet, I've long since noticed the potential for that to happen.

Perhaps an NVR (No Volt Release) switch would be an appropriate development by the manufacturers.

ATB (All The Best),


Plus 1 for the NVR.

The more recent machines have a soft start feature which is a significant advantage on a big angle grinder. A brake on switch off would also be a good idea.

My grinders are fitted with a short lead with connector for fitting to an extension lead which makes it possible to disconnect the grinder when changing discs etc without necessarily having to get to the socket outlet.

I am surprised that no one has mentioned the generally excellent PR88.

Glad to help and to know who the "we" are!

Although I have a shop-made equivalent of the Myford conversion set, I mostly just "play tunes" on the stud gear in the way that has been frequently mentioned here. Brian Wood's book is recommended on this topic.

Is it just a matter of packing out the new quadrant?

At first sight I thought the faceplate could be from GHT's UPT.

I am currently building a Quorn and having bored out the LH and RH casting, the front bar calls for a "sliding fit" between these cast iron holes and the front steel bars.


Are you slitting your Quorn bores or installing split cotters?

If I were doing it again I would definitely do the latter.

Michael Gilligan:

An earlier development in fastening technology was the tapered thread wood screw which I believe was due to GKN or, perhaps, just N.

I think it would have been nice if the OP (who says its all sorted now) had pressed a few more keys on his keyboard and explained what he wanted in the first place.

Ian P

and, respectfully, told us how he solved his problem so that others might benefit.

Michael Gilligan:

Thanks for the link and the thumbs up. It's good to know that my recollection was on the right lines.

The linked article mentions colour coding, an excellent idea in the circumstances particularly for bits with tiny markings. I think that Wera used to put a coloured ring on their bits.

Thread: What do you use your lathe for?

Couldn't that wrench have been mounted on a lathe's cross slide for boring?

I suspect most shop-made lathes have been the result of both lathe and mill.

The most common use of square drive screws in the UK is for pocket hole joinery where "kreg" are the common brand made popular by Norm on NYWS. That's about the only thing I use them for, driver does tend to stay in the hole well.

I got my Kreg outfit from Axminster before they went over to the ujk brand. The Kreg-supplied screws seem to be Robertson and drive very well as long as axial alignment is maintained. The ujk equivalent is T20 where the connection between driver and screw head is perhaps not quite so positive.

When Pozidriv came in I think the idea was that it could be driven with a Phillips driver but not the other way round which may be the answer to the OP's question.

A character in Victoria Wood's classic sitcom, dinner ladies, was asked if he had any real regrets about his life and replied that he blamed himself for failing to appreciate the importance of the cross point screwdriver!

This site does not (necessarily) have a country origin after your screen name - include it if you wish, mind. It does, however have a “profile” facility which, if everyone used it, could provide adequate info for most interested parties, were it to be used. It is there for exactly that purpose - to show your profile.

Plus 1!

I live in hope that those who have NDIY will see the point of posting a public profile with some general indication of their whereabouts.

Just spotted that the missing page is printed in Guy Lautard's The Machinist's Bedside Reader. By way of review of this excellent and informative work I will scan a brief extract and post shortly.

Sobering to think that these used to be made by hand turning methods. I believe this is an example:


I seem to remember that in his classic "The Practical Woodturner" Frank Pain suggested that the men who did this work went mad!

Many thanks for the link which allowed me to re-visit this inspiring story; I love the use of the "hide in plain sight" idea.

Does anyone have a link to the apparently missing page 159 or know if the lathe still exists?

Tungsten: means heavy stone in Danish.

Yes, it means heavy stone, but are you sure it isn't Swedish? See here.


Bra! They are two very similar languages as fans of "The Bridge" will know.
