« Part 32: Sell it and buy a new one Part 33 of Tool Tip series Part 34: Fancy a petrol powered Table Saw »

I have an Irwin square which I use often due to it being the only accurate square of that size I have got.

Well after years of use and possibly a little abuse I noticed a vey small amount of movement in the square.

As I rely on it quite a lot I decided to see if I could reset it.

No adjustment screws or the likes were visible so I assumed there was something under the plactic sides.
On further investigation I found there was a small amount of movement in the side covers but they would not slide off.

There was not a lot of space between the sides and the actual metal frame so I decided to poke a trimming knife blade down between the two.

I then slid a steel rule in and it stopped about 30 mm, now pushing the plastic side I found it would now slide off.

Looking closer there was a dimple in the plastic cover locking it into a hole in the metal frame but no adjusting screws, very odd I thought so I removed the other plastic side and found what looked like three really small “screws”

Using a magnifying glass I saw a round nut with a section notched out on the outside.

Wondering if I could adjust them I got a small punch and hammer and gave one a hit.
Sure enough it moved.

So I set my square in a vice and with my small japanese square set it back to 90 degrees.
Then gently tapped the round nuts up tight again.

Once that was done all the movement was gone and the square was accurate once more
I slid the plactic sides back on and returned to work..

I thought you may be interested.

Nice tip rc.

And to think that back in the 60’s we(I) poo pooed the Made in Japan stamp… Now we’d kill for it and they always come to our savour every time…

PS. Maybe we should just buy Jap squares… but how the hell could we correct them?

Japan: A topic that got little support from my Mom who was a WWII nurse

Yep the Texas Chainsaw has got nothing on the swift silent pull saw, whip your finger off quick smart.

I guess if you dropped it, it may go out of whack , and I agree a second one could not check it as well.
