How to Prevent Remove When Cutting Plywood?

Whatever sort of woodworking you do, at some point you are most likely to be using plywood. Whether you are constructing cabinets and utilizing commercially available plywood, make your very own veneer, or acquire veneer to apply to a plywood substrate, eventually you are going to have to take care of cutting plywood. The most significant issue woodworkers have with cutting plywood, particularly when cross-cutting, is that the veneer usually splinters out along the cut line. A lot for that expensive piece of veneer!

Here are some ways to avoid this:

Let is initial look at the tools used to reduce plywood, both for cross cutting and ripping. Big 4 x 8 sheets of plywood are usually torn using the table saw. When tearing or go across cutting on the table saw the good side should constantly be encountering up. This action alone will stop the majority of splintering on the good side. To ensure of this though, two things need to be done to your table saw. First, you need to be using a sharp 40 tooth mix blade, (my fave is the Forrest Woodworker II) or a high alternating bevel work blade, a specialized blade designed to cut melamine and veneered timber without splintering. Second, your table saw requirements to be tuned up. By this I imply that the blade needs to be alongside the fence. On the side encountering up, if you are only getting remove on one side of the blade, this is possibly the issue. If you are obtaining remove on both sides of the blade, your blade is wobbling due to being curved, or the arbor is not running true. It helps to have a dial indication to tune up your table saw.

For cross reducing huge sheets of plywood, even more times than not, I will use a circular saw? If you think of the round saw as an upside down table saw, it will certainly make good sense to ensure you cut with the silver lining encountering down.

MDF Boards Cut to Size

Here are four ideas for utilizing a round saw to get a clean cross cut on plywood:

1) The same blade considerations we speaking about for the table saw put on the circular saw.

2) Score the plywood initially by setting the height of the blade simply deep adequate to rack up the top veneer. Go back and reducing all the through. This method functions very well if you utilize a fence so you can make the specific very same cut two times. Free handing a cut such as this would not work.

3) An approach I such as to utilize to aid stop splintering on the bottom side when making use of a round saw is to make use of a backer mdf cut to size. Use a sacrificial sheet of economical MDF below your plywood. Lower the blade to simply reduce below the thickness of the plywood. The MDF will certainly support the fibers of the veneer, keeping them from removing.

4) An additional technique is to utilize a strip of painters tape or masking tape along the cut line. The tape imitates the back board in the previous method. A job of care right here. Do not make use of tape that is real sticky, it will certainly end up pealing up the timber fibers beneath, precisely what you were attempting to prevent. Which ever before kind tape you use make certain you remove it as soon as the cut has been made to stop it from thawing to the plywood from the heat of the blade?
