Neat trick for cutting sheet goods on a good table/bench top!

[PTsideshow]

While I was watching a video on another subject, they had a shot of the shop in the background was a 4x8 bench top that had a blue insulation sheet on top of it and what was left of a sheet of underlayment that was cut up leaving shallow cut lines in the foam. I thought it was a pretty slick idea since it will work on grass,gravel or concrete.
I tried it this morning and it worked a treat! So I thought I'd pass it along, shallow cuts and you can use both sides. I generally have a two foot section on hand for other stuff.

What was the finish like on the underneath? Was it splintered or a nice neat finish???
Thanks for letting us know, neat hint.

I use the same concept when cutting window mats for photographs or other art work. Never thought about doing that with a circular saw.

Thanks.

I do that when I cut melamine sheets down to size, it cuts down on the edge chipping.

I've been breaking down sheet goods like this for years. At my age, I can no longer handle a full sheet by myself, especially MDF, though it was probably never a good idea to do it alone on a table saw.

You have to understand that I am not a finish carpenter nor a fine woodworker. I do like the bottom of the cut to be as good as possible.
After a good carbide many tooth blade for sheet goods and a firm pressure on the sheet. The next biggest thing seems to be the materiel you are cutting. Lately it seems that some of the import underlayment sheet will splinter no matter what you do!

It gives a pretty good cut on the side touching the insulation, a lot better that open air cutting between supports.

I cut this with my 5 1/2" battery circ saw with a general use around 20-30 tooth carbide blade I don't remember the number it is a Dewalt blade. I have a trim saw circ saw with a panel blade for the good stuff.
