Best saw for cutting plywood,little cottage playhouse instructions,hand carved teak wood panel,house plans with walkout basement and pool - .
In addition to the circular saw, all I need is my tape measure and framing square, a shop-built jig, and a couple small clamps.
After the glue has dried, run the saw against the fence, trimming off the bottom piece of plywood.
If you make any of these for your own shop, or come up with a variation or improvement, send me a photo of the results.
This puts the plywood at a convenient height, and the saw blade will nick the edges of the beams rather than cut a slot across the flat surfaces.
For a minimal investment, I can cut plywood as accurately as I can with a table saw, though it does take a bit longer. I glue the plywood down with yellow glue, using narrow crown staples to fasten them to the edge of the board below. So for a circular saw and miter saw, make your cuts with the good face down; on the table saw, with the good face up.
You can also do this with regular sawhorses, with two or three sacrificial 2 x 4s spanning them.
I use the saw to cut close to the desired line, then use a router and a straight guide to get a very clean precise final cut. These blades will work for rough cuts in construction-grade soft lumber, but for working with hardwoods and sheet goods, you need to upgrade. Adding low-adhesion blue masking tape to both faces on the cut line holds the wood fibers in place while cutting plywood. You want the plywood to be fully supported as you make the cut , you don’t want the cut off piece to drop as the cut nears completion.
Both of these tools can be used for a greater variety of woodworking jobs then a circular saw. So get some help: Ask a friend or family member to assist, or use a roller stand or sawhorse to keep things flat.
For table and miter saws, invest in an 80 TPI plywood blade, one designed for cross (miter saw) or rip (table saw) cuts. That way, you can focus on pushing the wood or saw at a consistent feed rate, getting a cleaner, straighter cut.
The only critical dimension is to leave a space from the edge of the skinny piece to the edge of the wide piece that is bigger than the distance from the edge of the saw’s baseplate to the edge of the blade. Also, whenever you use a circular saw, set up a straight edge or fence to guide the foot of the saw.
