Right hand threads

[egaParticipant @ega]

I started a thread over on the Tormek wet grinder website about their "EzyLock" nut. This is a 12mm x 2mm pitch circular milled-edge lefthand nut which retains the stone on its shaft. In use, the nut is just lightly spun on counter clockwise with the fingers and the clockwise rotation of the stone then causes it to tighten sufficiently.

It seems that users had difficulty in removing the nut even with tools and despite the fact that they were attempting to turn it in the correct, clockwise direction whilst, I believe, holding the stone still. Tormek's prescribed procedure, however, is to immobilise the shaft by grasping the honing wheel on the other end and rotating the stone clockwise which causes the nut to undo.

This procedure is unintuitive at first sight but apparently works every time and I think depends on the coarseness of the thread and the leverage of the 250mm diameter stone. For anyone interested, here is the link:

Incidentally, the Tormek is aimed in part at woodturners, many of whom are ambidextrous.

but not all people who appear LH are,

Very true. I shoot from the left shoulder as my left eye is master. Done it ever since being knee high to a grasshopper. Aiming the cork guns at the local fair was when I started it, as I could not comfortably close my left eye while keeping the other open, whereas the other way was easy. I still used to operate the bolt on my rifle (Browning T bolt) with my right hand. I bought it because it was a sliding (rather than lifting and sliding) bolt action.

Also, a mate at school was right handed for everything except batting at cricket. His dad was left handed and taught him that way. He bowled right handed, of course.

I'm all over the shop !

Throw a ball and write left handed and everything else right handed but when it comes to welding i stick weld left handed but tig and mig right handed ! I used to drive my welding teachers mad as i used to switch hands all the time !

It has been a handy thing though as i can weld equally as well either hand in any position .

I would say i'm right handed but was taught to write and throw a ball by my left handed sister .

I could never master shooting opposite hand though – it just felt wrong !

I never could write left-handed, but I was ambidextrous with most tools – and thank goodness for that, because five years ago a stroke took away most of the strength in my right hand. When you think about it, most of the important controls on a lathe have to be used with the left hand. Like Ian, I never could use a long gun left-handed, but I could shoot a pistol with either hand. My dad was at one time a keen cricketer, and he used to bat left-handed and bowl right-handed – he always said because he was taught to bat by a left-handed coach. A medical professional who treated me for right-side tennis elbow told me to fish left-handed until I recovered, and it was not as difficult as I had anticipated.

Going back to the original post its probably like who invented the wheel and we will never know the answer ! However you all must realise we lefties were picked out special — to be different to the crowd !!!!!

Me well I write left handed, shoot right handed, etc etc the fact is we just do what comes naturally and as far as tools are concerned it never causes me a problem that most are designed for RH people.

A chap in a Beatles tribute band who went into great detail to look the part as well as sound right had to learn to play bass left handed, you can't have a right handed Paul McCartney.

They were following the sun, which appears to rotate clockwise through the sky. Hence anticlockwise or left hand threads are 'widdershins' – against the sun.

That threw me for a second… I'm in the southern hemisphere!

[JOHN MANTOVAParticipant @johnmantova72105]

Witches covens dance "Widdershins" I believe Hehee

[not done it yetParticipant @notdoneityet]

Yes, but the word 'clockwise' was conjured up, to describe the direction only relatively recently – the Sun had been doing that (apparently) since the solar system developed. We now know that, as Mick was careful to write, 'appears' is a way of saying the Sun does not actually move in relation to the Earth – without further confusing the poor souls who still apparently believe the Earth is the centre of the Universe.

A bit like the statement that 'the Sun has come out from behind that cloud'! Not a shred of truth, but continues the fallacy to future generations.

Even as late as 40 years ago kids here were regarded as something weird if they were lefthanded,and beaten in school for being so. How do I know ?,been there,done that,still doing it ! Still use hammer and hacksaw,screwdriver ect left hand,no problem. But I,m still WEIRD !!!

[larry PhelanParticipant @larryphelan54019]

Just thinking a little more about this,I remember when other guys came to use some of my equipment in my workshop,they were never quite at ease with the layout.Everything seemed to be in the wrong place [which it was,for them ] Without thinking about it,I had set it up to suit myself,so everything was ideal for lefthanded use. Still is.

They could never understand how I could use my Skill saw with my left hand,since all these machines are made for right hand use.Still,although I use all hand tools left handed,I have no problem using drilling machines,chopsaws,ect Rt handed

Before I was "corrected" I used to write with my left hand,quite clear writing too,but this was considered to be the mark of the EvilOne,so it was beaten out of me and I was forced to write Rt handed with the result that my writing is so bad that I can just about read it myself,if I,m lucky. I,m told they have a more enlightened view these days,too late for me since I have sheets of notes I took years ago which might as well be in" Chinese of the day" for all the use they are to me.

So I say "LONG LIVE THE LEFTI"

[Mike PooleParticipant @mikepoole82104]

I don't think my hand writing could be any worse with my left hand and I am right handed.

Mike,

Are you a doctor? They are, apparently, among the worst for legibility!

[martin perman 1Participant @martinperman1]

My only difficulty was when using a Lee Enfield .303 rifle in the ATC as I had to pass my right hand and arm over the rifle to work the bolt as it was away from me.

My writing is unreadable when using my right hand, I have no control.

Non comprendez!

[MikeParticipant @mike89748]

Yes, Martin – firearms manufacturers have always seemed slow in producing rifles and shotguns for left-handers. If you fire a right-handed auto shotgun off your left shoulder, you get a hot spent cartridge case in your face when you pull the trigger. If you try that trick with some military rifles, you get smacked in the eye by the bolt handle. During WW2 a pal of my dad's got held to ridicule for suggesting the formation of a left-handed regiment, with left-handed rifles and other weapons.

There is, or at least was, a left-handed rifle club, and I can recall seeing them shoot at Bisley in the 1980s. And one of our leading competitive rifle shots, Barry Dagger, was left handed. But then, Leonardo da Vinci and Albert Einstein were also left-handed.

[martin perman 1Participant @martinperman1]

Now I cant tell my left from right I meant my left arm over the top of the rifle to use the bolt, the right arm was in the sling, I had the stock in my left shoulder and sighted with my left eye, the bolt was operated by the left had as was the trigger.

Doctors go on a special course to teach them how to write like that! Chemists go on a similar course to enable them to understand it. That they do so,never fails to amaze me,it looks like it was done by a spider with a bad leg.

Just try to make out the name on the warranty on some of your gear,I never could.

I recall a program some years ago on "That,s Life" dealing with this subject and some of the examples were a sight to behold,and no mistake !. Most of them were from people holding important positions ! Enough said !

There,s hope for us all !!

[Richard S2Participant @richards2]

Maybe if the Screw Thread was invented in the Southern Hemisphere, it might have been L/H form…..same way as water goes down the Plug 'ole !.

I'm also a generic 'Leftie' like writing and most agile/strongest arm and hand, All over the place otherwise- Golf,Cricket, Chainsaw, Drill and eat with Knife R/Hnd'd , Handsaw, Shoot and use Screwdriver/Spanners with Left.

I steer clear of Black Powder Flintlock Muskets !!!!!.

[larry PhelanParticipant @larryphelan54019]

Let us rejoice that we have some of the greatest men of history on our side !!

Just wondering——Does that mean that we should be better able to cut left hand threads ?

Just wondering,that,s all !!

Used to shoot with a guy who modified the bolt handle  on his  .303 so it stuck out the left side of the rifle , basically he just lengthened it and bent it so it looped up and over the receiver .

Looked funny watching him shoot it as the bolt had to be cycled upwards to lock it .

[MikeParticipant @mike89748]

This was a quite common modification to Anschutz .22 match rifles in the 1980s, and yes, it did look odd to see someone lift the bolt to lock it. Eventually they got around to producing "mirror image" actions.
