Sawing a $50 sheet of Oak Veneer
« on: February 08, 2010, 02:55:01 PM »
My project requires me to saw up a 4 x 8 sheet of veneer. I will saw it on my Powermatic with a 72 tooth blade, but the bottom of the cut always have some splinters.

I suppose a $200 - $300 blade would help, but it won't happen. Any suggestions to get a better cut?

The insert on the table top around the blade might not be flush with the table and possibly not close as it could be to the blade on all 4 sides. Try making a home made one from a 1/2" sheet of plywood and cut the hole out by raising the blade up through it. See if that works any to cut down on tear. Maybe even score the pencil line with a utility knife before ripping.

Helps with stacked daddo blades.

Pre-commercial thinning pays off. :)

I've heard it recommended to place a backer board of scrap against the good board to stop splintering too.

Perhaps another sheet of plywood beneath the  expensive veneer, if you can keep it tight. You might even experiment with gluing one to it temporarily.

I must say, that's pretty cheep veneer compared to here. Shop grade 1/2" Oak alone is $80 a sheet.  But so isn't yellow birch. :o

Put masking tape on the bottom side of the cut. This helps reduce the tearout greatly.

What the others have said plus only raise the blade just high enough to cut through the material.

Do two passes per cut. The first pass is a scoring pass with the blade raised just enough to score the substrate, The second cut is thru' and thru'. A sharp blade is just assumed.....

Plywood does need a sharp blade, as well as a virgin insert in the table top. Sawing across the grain on the face plies will be the hardest ones to make without some splintering.

How thick is the panel?

Brand new zero clearance insert for the saw and masking tape on the top.  Use the blue kind and when you remove it pull at a angle slowly.  Also make sure your rip fence is aligned to the blade...if it is pinching a bit at the back it will pull splinters on the crosscut no matter what you do.  I normally also run a splitter.

The Sheet is 3/4 - and bought from home depot, it is red oak and cost $40 + two 3/4 inch dowels for a total of $50 when I looked at the recipt. Other hard wood were in the $55 -$60 range. Prices are down because there is no building.

I have a new insert that I haven't cut the blade a thru, will give it a try on some scrap.

I forget the article I was reading, but some guy had wrote in saying to spray rubbing alochol on the cut line were the saw comes out and that it soften the wood fiber so that it cuts better. Has any one tried this?

I know that scoring works, has anyone bought a scoring blade add on for the Powermatic or Delta? Which way would run the board thru to score, teeth coming out or into the board?

I think that the scoring blade turns in the opposite direction of the main blade.

I cut-up my sheet of veneer and used my new zero clearance saw insert, found that a better job was done on the bottom of the sheet than on the top. I had the saw raised about 3/8 of an inch above the cut. The quality of the cuts require no further work.
