Best saw to cut plywood for furniture
I am building a desk from plywood, 1/2" and 3/4". I used a table saw
and circular saw to rough cut after I marked the layouts on the boards, leaving about a 1/4" extra on each side. I'm trying to get smooth straight edges, but have been failing so far. Table saw seems not smooth enough. Circular saw not straight enough. I plan on working on more furniture in the future, nothing fancy, and probably most plywood or pine. Would a band saw be a better option? Jigsaw, scroll saw...? This is more just hobby right now, but still want to do better than what I've ended up with so far. Thanks, Scott |

No, just a plywood-suitable blade for the table saw. Assuming 10 inch, 80 tooth with a 30 degree alternate top bevel. Even that may not prevent splintering of the veneer. Plywood veneers anymore are paper thin, no, onion skin thin. Scribe your cut line with a utility knife before you run it through the saw. -- NuWave Dave in Houston |

Normally on a table saw you cut plywood with the good side up, and with a circular saw, with the good side down. A sharp blade and one for cutting plywood is recommended, but if you only have the one blade you can try the following: With good side down and blade lowered, make shallow scoring cut through veneer; raise blade, and with same edge against fence as scoring cut, flip plywood to good side up and finish cut. Try it on a scrap piece first. YMMV ... -- www.e-woodshop.net Last update: 1/06/07 |

If the tablesaw is not smooth enough, you need a different blade. If the
circular saw is not strait enough, you need to use a saw guide. wrote in message oups.com... I am building a desk from plywood, 1/2" and 3/4".

I think you'd get the results you are seeking with a Forrest Woodworker II
blade. It cuts smoother than a jointer can do. Don Dando wrote in message oups.com... I am building a desk from plywood, 1/2" and 3/4".

What kind of saw & blade are you using? A straight line can also be cut with the hand held sirculars saw if you use a guide of some kind. Google for "saw sled" or "saw guide" and you should find a few ideas. -- Often wrong, never in doubt. Larry Wasserman - Baltimore, Maryland - |

Morris's suggestion of a router is a good one, as is making scoring cuts prior to cutting. A zero-clerance insert will also help with both the table and circular saw. My saw will do it no problem, but when I had a little benchtop, my technique was to cut about 1/16" to 1/8" oversized, then clamp a drywall square to the sheet and use it as a router guide. You don't necessarily need anything fancy bit-wise; if your router has a round base, you can just set the straightedge so that the baseplate rides against it. Take light cuts in passes of about 1/16" to reduce chipping if that's a problem. You can also try sticking a piece of tape to the underside of the plywood where you'll be cutting when using the table saw. It doesn't always work, but it can help with chipout with some plywood. And of course, use a plywood blade. |

Thanks all for the the suggestions. I picked up a Freud Diablo 80
tooth blade...ripped through the boards, very straight and smooth. I didn't use tape, but will remember that tip for later. I was trying to figure out a way to do it with the router, but couldn't see how best to run the straight line. The idea of clamping a straight edge of some sort to the the board and running down that seems obvious now, may have just been one of those weeks. What is the advantage of a zero clearance insert? One person mentioned it helps prevent tearout. And you mention using it for table and circular saw. I googled it some, did get some ideas, but didn't see how it was used with circular saw.

One person mentioned it helps prevent tearout. Supports the board up to the very edge of the kerf. Makes your saw less likely to eat and jam itself with narrow cutoff scraps. Flatter than the stock plate that came with your machine, which will now cut square edges for the first time. And you mention using it for table and circular saw. I googled it some, did get some ideas, but didn't see how it was used with circular saw. Bolt a piece of 1/2" ply to the sole. Clamp everything to a bench, with the blade overhanging the edge about 14". Raise the blade, turn on the saw, and plunge the blade through.

The idea of clamping a straight edge of some sort to the the board and running down that seems obvious now, may have just been one of those weeks. IMHO, best way to do the job if you must have a smooth edge. Pick up a 2"x2"x1/8"x96" aluminum angle and a couple of 3" C-Clamps to use as a straight edge. Great straight edge for either a router or a circular saw. Lew |

: *snip* The table saw is a Delta shopmaster, nothing fancy. I bought it a few years ago when building a shed, have used it since cutting up pine boards with just the stock blade it came with. Probably time to get a sharp blade. You'll probably need to replace the blade this time, but if you get a good quality one you can get it sharpened. I've had the TS I have now for about 2 years, and just made a few cuts here and there and it's about time to change the blade. I really should do that before I use it next.

Generally speaking, cross cuts are the worst on plywood.
Ripping can be solved with a decent, "high tooth" count blade. You solved that. Build yourself a couple of "guides" out of scraps. http://www.woodworkingtips.com/etips/2004/08/13/wb/ You need a "long" one for ripping up sheets of plywood and a "short" one for doing cross cuts. You can use the "exact" jig with a router for "trimming" ends. You will want to build a "basic" router table at some point. This is a much easier way to control a router. http://www.woodworkingtips.com/etips/etip040700wb.html I would also consider buying a basic "combo blade" like a Freud LU84 which is excellent for every day cutting.

I've used drafting tape. The adhesive isn't agressive and it seems to have just enough "hold" to keep the wood fibers at the cut line from lifting. Seems as if at one time drafting tape and masking tape were identical, or nearly so; but the masking tape I looked at last trip to the lumber yard now comes in all kinds of flavors... | Is it necessary to remove gunk from the blade after every cut when | using tape? I didn't find it so; but it's probably a good idea to eyeball the blade from time to time.

Regular masking 3/4" wide tape has always worked fine for me, but you might want to try some of the blue painter's tape which is not as aggressive as regular masking tape. You want to put the tape on so that the saw cuts down the middle and force the tape against the wood with heavy finger pressure. Never had any tape adhesive get on my saw blades, but you want to keep a watch that any tape doesn't tear off and ball up raising the wood a tiny bit. Not a problem if you use heavy pressure when applying and smoothing the tape. |

"George E. Cawthon"
fine for me, but you might want to try some of the blue painter's tape which is not as aggressive as regular masking tape. I've been meaning to try out that blue tape. Last time I painted my apartment and used masking tape on a few areas, when I pulled it off it took some of the original paint with it. I was so disgusted at seeing the pits in my apartment wall quit painting immediately and left it that way for several years before I got to plastering it and then painting it again. I should have know better, like what apartment super is going to use premium quality paint that doesn't flake off at the slightest irritation? |
