How to stop this cutting problem - TilersForums.com

Is the bar adjusted evenly?

As Antonio says, break 10-20mm from the tile edge.
Also helps (with "sensitive" tiles) if you nudge the tile away a few mm up from the measure bar before breaking.
And make sure there are no bits of rubbish under the tile, clogging up the spring beds in that area.
I also find that on longer tiles, a little backward score - say 50mm, before scoring forwards can help a clean break.

I back score every tile

I back score every tile

It seems many /most do.
I'm lazy!

Well as is common, as soon as I had posted the question I found the answer!
It seems on the last couple of jobs using smaller tiles I have begun to start crunching the tiles from the far side of my cutter instead of at the measure side, when I realised what i'd been doing and started doing it PROPERLY, I had no further troubles. (silly b*gger)

Thanks for the responses

ps what do you mean by back score @impish?, make a deeper score?

It's to make sure you score that first bit of tile properly . Put your handle 50mm past the near edge of the tile then score back towards you before you do your normal score.

Old machine.

My old sigma cuts porcelain like this. My new montolit cuts them perfect.
