Pelmets chipping with a Chop Saw - Blade / Technique

[SkipFeeney]

Hi,

I am trying to cut some high gloss pelmets. I am using a chop saw with a 40 teeth blade and its chipping it quite badly. If i invest in a 60t blade will that make a difference?

Also is there a technique to it? Do I turn the pelmets upside down and plunge the saw downwards through it? Or do I slide the saw out and then slide the saw backwards through it?

Thanks

Lower blade very slowly .

What diameter blade are you using? 40t sounds like the sort of blade I'd use on softwood carcassing only unless it's a very small saw. For high gloss pelmets and cornice on my 250mm saw I generally fit a 72 t to 100t blade. Using a lower tooth count blade can work if you feed very slowly, but your blade must be sharp - if it isn't (as in you have done 5,000 cuts in softwood) then resharpen or replace it because a blunt blade never cuts well.

The only safe technique with a sliding compound mitre saw is to pull the head out drop the head then push it back towards the fence.

Flat pelmet? Router cut.

Or masking tape prior to cutting to stop the chipping

fine tooth blade and go very slowly.
