Pythagoras theorem

[Dougs Third Go]

5x5 + 12x12 = 13x13
25+ 144 = 169

The sum of the squares etc.

exactly John, I knew geometry had some uses when I was at school

Great thread. I tend to use this method and it seems to have been ok to date. Out of curiosity which part of the room do you guys tend to measure from to get your initial centre line. If the baths in do you tend to drop a level from the bath, ping a chalk line then measure out from that.

Can’t see any reason to use 345 in a small room it’s likeusing a water level to set out a bathroom

Im finishing off a bathroom tomorrow 3m2 floor.... I'm gonna build myself a pythagorator with some wood and nails!!

The pythagorator.... Sounds like a super hero.... Now what super powers would the pythagorator have??

Don't forget Pythagoras theorem only works for right angle triangles....

Forum was upgraded a few days ago and likes and thanks are not working with Tapatalk. I did start a thread on the subject.

Ok cheers SR, I'LL have a look for it

Cheers Diggy

But you can bisect the angle and set the floor out to 45 degrees!

Pythagoratyor - snake like features and an ability to spit accurately from 345 feet!

I used to use the staff with masonary nails method for many years. I still would on larger floors.

What you call a staff I was taught by the old tilers this method but it was called a Pinchrod,have not used this method much now just use the Stanley set square now.

So now we have the full superhero team The Pythagorator and his trusty sidekick Pichrod and their faithful butler Stanley...

Anyone want to buy a stanley square? I don't need it anymore ... Ps Alan, too far, you've taken it too far lol

Alan I was tempted to do the squaw on the hippopotamus, but I thought no.:lol::lol:

I just couldn't resist... And then when the pythagorator turned up... Well I just get carried away sometimes...

 

[The Legend; Phil Hobson RIP]

Good on you Alan.

 

[charlie1]

... When your tiling on diamond then obviously Pythagoras goes out the window... You need to use dimagoras theorem ... Totally different but freakishly similar.

Brilliant thread, very illuminating. All posts (well the sensible ones) have been duly noted and this will be something to go into the paper alongside the pinch rod posts, thanks!

Cant see whats so funny about the pinch rod worked for a tiling company that had been going for sixty years
It employed nearly 20 tilers some were on the firm before WW2 and any marker rod was referred to as a pinch rod.

Ok, how would you actually apply this method in a tiling situation? I've never really had to because the largest floors I do are 50-100 m2 so just use my folding square. The reason I ask is because I was working with another tiler recently and he was giving it the big 3-4-5 rule so I asked him to show me, I quickly realised yes, he was well aware of the theory like myself but he had no idea how to put this in to practise.

Its not about the size it will work with any measurement eg. mark 300mm one way 400mm another and to make a right angle the distance between both measurements should measure 500mm. any measurement x3 then x4 will make a right angle when the distance between your marks is by x5.

 

[panceramicsltd]

Always use it especially when only doing a smaller floor saves carrying another bit of kit

 

[thompsonbrown]

You know what they say. If its not a right angle its a wrong angle.

Yep, i understood the theory fine, it was actually how to use it I was struggling with but it was explained in one word "arcs" very simple really.

Unfortunately Lawrence my mate 'Pythag' and I copyrighted this theory a few years ago and since he's not around anymore all royalties go to me! So any mention of his name ( alphabetically he came first) - it was originally ' The Pythagoras Timeless Theory of setting out Tiles' , and my retirement fund is credited. All correspondence reference the usage of this theory should be addressed to my solicitors Hadaway and Sxhite, 999 Letsby Avenue, Newcastle Uon Tyne.

Just toooo far
