First, welcome to my brand-new blog spot on my new, updated and improved website.
Many people tell me that they have difficulty cutting hard plastic and laminate without chipping the cut edge.
There are two main reasons for this to happen.
The saw blade is too coarse for the thickness or hardness of the material
The material is overheating and clogging the saw blade.
In an ideal world everyone will have the correct saw and blade selection for every material but that is not realistic so here are some tips to get the job done with basic tools.
Whenever I cut plastics, whatever the material I always put a strip of masking tape where the cut is going to be. Using a hand saw the tape will be on the top and underneath with Jigsaw or circular saw. By cutting through the paper masking tape, it stops the plastic particles from sticking together and clogging the blade.
When cutting hard plastic sheet eg. Acrylic (Perspex), HDPE, Polycarbonate etc. it is a good idea to have a fine-toothed blade when using a jigsaw or handsaw. A crosscut blade or similar with a circular saw.
When cutting laminate eg. Kitchen worktop always use masking tape on the laminate side. Cut from the top with a hand saw but turn the worktop over and cut it upside down when using Jig or circular saw. This is to ensure that the saw teeth cut into the surface of the laminate and the tape to reduce tearing and chipping.
That is all for now but there will be more tips from the me soon.
If this is useful to you let me know.
Keep safe everyone
