My wood working projects started with a upcycled palette wood. We do have ocassional palette wood from the office that is free for the taking. This is really a good practice work.
Beginer wood working made easy with a circular saw.
I have a Bosch GKS 12 V-Li for a few months and I could say this is quite a handly power tool. The tool is powered by a 12V Li battery. It is light and easy to use. Angle and depth of cut can be adjusted using wing nuts.

This came packed with a Standard Wood blade. The circular blade is a 85mm with 24teeth designed to cut multiple types of wood.
The basics of wood cutting
Cutting wood with a circular saw (probably with any saw) is just 2 methods.
- Rip cutting which is cutting along the grain of the wood
- Cross cutting which is cutting adjacent to the grain
Most of the time Rip cutting along the grain creates a clean cut while on the other hand Cross cutting requires technique and tool to get a clean cut.
With a circular saw, a blade with more teeth produces a much cleaner cut compared with a blade with a lesser teeth.
During the Lazada 11.11 sale, I got a Standard Multi-Material Blade for my Bosch GKS priced during the sale at 799PHP (Regular 899) with 104PHP shipping. This blade is also 85mm but with 30Teeth. 6 teeth more compared with the Standard Wood.
This blade is supposed to be Multi material, but I will be using this for plywood. Also I could not figure out what material is indicated on the table.
Replacing the blade is as easy as using the saw to cut.
Make sure to remove the battery before replacing the blade.
Use the allen wrench that comes with the Bosch GKS 12V-Li which is kept at the belly of the saw.
Insert it on the lock chuck. Depress the Spin Lock all the way while turning the wrench counter clockwise. Don’t depress the Lock while the Saw is operating this will break the gears.
The Blade Lock will pop out after removing the nut. Just open the blade guard and remove the blade towards the Saw shoe.
Insert the new blade and reverse the steps. Double check and make sure the blade is locked in place.
Clean as you can get, 6 more teeth does make a difference
The pallet plywood is not really of good quality and easy to tear. The Standard Wood blade works but produces more tear compared with the Standard Multi-Material. Using this Multi-Material Blade pared with technique would produce clean cuts.

Clamp the work
Clamping keps the work in place. The cut out should be free to fall. Clamping this side will cause the work to kick back which is dangerous. I am using 6″ clamps from Tolsen
Cut with the face down
The Face of the plywood is the side which is the more presentable. This is the side that we want to see and show from our finish work. It is important that we cut face down. Cutting tear will mostly be created on the side that is at the top during cutting. Again always cut with the face down.
The Standard Wood and Standard Multi-Material blade produces the same cut on the Face.
Just enough teeth to sink in
I measure the depth of the teeth before making any cut. Just making sure enough depth of the teeth should extend from the wood. This would prevent the blade from recieving unnecessary strain.
