How to change the blade in your circular saw. I recently received new blades for my Ryobi cordless circular saw so I immediately put in a new blade.
Changing blades in a circular saw is quite easy, but many people have actually never done it. Many people just keep cutting with the original blade forever as it gets slower and slower and starts to make sloppy cuts.
A new blade makes a cleaner cut and saves wear and tear on your saw motor.
FIRST – remove the battery or unplug the saw before you proceed for your safety.
There is a brake on your saw on the top somewhere. Pressing this button locks the blade in place so it will not rotate. This allows you to remove the retaining screw.
The retaining washer has an arrow on it showing which way to loosen or tighten the blade.
Turn the screw to loosen the blade and remove both the screw and washer.
Now you can lift out the old blade.
The blade guard of the saw has an arrow showing the direction of movement. The blade also has an arrow on it. These should both point in the same direction.
Put the blade in place and then the retaining washer. Now tighten the screw to lock the blade back in place while pressing on the blade brake.
Now replace the battery (on a cordless saw) or plug in the power cord. Turn on the saw for a second and watch the rotation of the blade. Make sure it is turning in the correct direction.
Now you can get back to work in your wood shop.

My goal is to provide the small scale recycler/scrapper/scrap yard an affordable, effective, and versatile processing and sorting line for smaller volumes of scrap metal to increase the overall value.
I am very interested to hear your comments/suggestions on a small scale scrap metal processing line. Is this something that the small scale recycler would be interested in? Is there a market for equipment like this? Would this be a useful tool for the industry? Your comments or suggestions would be much appreciated
I wanted to make a video showing the feasibility of processing contaminated/dirty brass through a hammer mill and separating by hand. This was a rough 1st pass study to find out if there was enough added value to make it worth while. The results were encouraging and I think there could be a real market here for upgrading/processing dirty brass if there is enough available volume.
The processing through the hammer mill took about ~15-20 minutes (10 lbs/minute average) and the real time sink for this test was the hand sorting. It would have helped if I had a sorting table, the proper tools, and a grinder to help determine the difference between the different metals. I think the hand sorting time could be cut down quite a bit with the right set up.
