Tile trim curving

[Grant]

I was wondering if anyone could give me advice on how to cut tile trim at an angle straight, almost every time I try it curves. I've tried different blocks and saws but it hasn't made any difference. Is there a certain way to do it for a straight cut at an angle?

Thanks.

Hello Grant and welcome...

Have you tried a mitre box...?

Thanks Dave.

Yeah I've tried different mitre boxes and it's curving when I cut it. I've tried cutting it slowly as well but still didn't make much difference. Not sure where Im going wrong.

I cant understand why this is happening, never had or heard of that problem before. What trim are you cutting?

OK... How about pre-formed corner pieces..?

I'm cutting stainless steel at the minute but also had this problem with plastic, I've had a couple of people around to have a go and it's curving for them too.

They would be perfect, they didn't have the right sizes in the shop I was at today but I'm sure I could find them somewhere. Cheers

When you say "curving" do you mean that when you offer the two mitred ends together the appearance is that the ends of the cut touch but bow apart in the middle?

I'm guessing that you are laying the trim flat when you cut instead of standing it up in the mitre block?

I've had it before with a cheapo mitre block, too much play in the middle of the guide can give the curve, the saw starts straight then strays off , goes adrift in the middle and straightens towards the end, that was my thoughts on it, at any rate, I don't have the problem now with a decent block.

Yeah that's exactly what happens.

I'm standing the trim up ways, is that the right way?

It's a stainless steel block I have but there is a bit of room for the blade to move about in between, that could be the problem although I've tried other blocks and saws

An out of square corner will throw the joint out as well..

If it doesn't work with the trim stood up in the mitre block, then try cutting with it laid flat. Use a couple of bits of off cuts until you solve the issue.

might be stating the obvious, but make sure you cut the mitre exactly as you want it to lay on the wall..ie. push the trim perfectly flat against the back face of the box to form a right angle...failing that you can get handheld mitre cutters for trim a bit like secateurs with the angles marked on..might be easier if you're struggling with a box?

 

[Grant]

Thanks for the advice lads, I'll have a go at trying to cut it using the methods suggested

Use a file on the dodgy cuts untill the curve disappears.
