Plywood Dust Collector
Introduction: Plywood Dust Collector
I have a little basement workshop and I like to do all kind of things of wood and plywood.
I have Makita vacuum cleaner and it's afwul lot of makita vacuumbags that I use when using tablesaw etc.
So I purchased this dust cyclone and that needed a bucket or some sort of container where the dust goes.

Not sure is this the same but similar.

Plywood
Window seal gasket
I had 10pcs of leftover plywood for free from our local wood seller. Size was about 84cm x 22cm, thickness 21mm.
I have seen many times from youtube-woodworkvideos when they are cutting parts in angles and then gluing those together.
So I had 10 pieces of this size plywood. I figured different angles how to join them together.
Circle is 360 degrees.
So if I use 5 pieces. Then I would have to divide 360/5=72 degree for the corners, and that is divided 2 because in joint corner is two pieces. So 72/2= 36 degrees. So every piece of plywood will be cut in 36 degrees both sides with tablesaw. In every piece of plywood is two 36 degrees = 72 degrees. 72 multiply 5 is 360 degrees.
But I have 10 pieces, I want to use 9 pieces and leave one just in case if I mess up.
So same calculation.
360/9 = 40 degrees and that is divided by 2 = 20 degrees. So I have to cut every piece with tablesaw blade in 20 degree angle. Both sides have to be cut like in the picture.
So Nonagon calculation for the area would be this.
When a is about 18cm. Then we can calculate 6.18182 * (0.18 * 0.18) = 0.20029m2
The inside height is about 0.73m so 0.20029 * 0.73= 0.1462m3
So the inside volume is almost 150 litres.

Step 1: Making the Frame
After cutting all the 9 pieces of plywood it was time to glue them together.
So first I placed those all to table and taped the outsides together. I tried to glue them all at the same time but that did not go well.
Taping all the parts together was easy but turning over was not so easy. Tapes did not hold that so well.
So then I made 3 pieces at the time. 415
I only used tape to hold them down when glue was drying. After those 3 pieces were dry, I turned the all up and glued all together.
Amazingly I got all together and it was kind of strong join, even I only used glue.
This dust collector must be air-tight, and my cuts were not so good so ended up using this moisture insulation inside all the corners. It makes it also stronger and that was also a good thing.
( I think it's somewhat same than fiber glass would be used inside corners.)
Then was time to do the bottom. I just used screws to attach bottom plate to the frame and then I used router to cut it flush with the frame. Unfortunately I dont have any pictures of it.
Then I used moisture insulation also for the bottom corners so it will be also air-tight.
LID
Before making and attaching the bottom I placed plywood under the frame and drew inside lines with pencil. Then I cut those lines with hand circular saw. This part of the lid is inside the frame. Lid is made of two parts.
Then I made the upper part of the lid. I cut it roughly on size and just placed it in the right place with 3 screws, then I again used router to trim it flush.
So then I placed inside lid-part inside the frame, then I placed upper lid-part on the right place and attached those together with 3 screws.
Then I took the whole lid out and used 8-9 screws from the inside and took out the 3 outside screws.
Step 2: Surface Finish
This is water proof plywood so its not so good for painting etc. I tried to sand it first so the paint would stick there. But it was not so good.
After painting I drill a hole for the cyclone and placed it with 30mm screws and washers. I also used gasket which came with the cyclone.
Then I just made letters with CO2 laser cutter and attach those with nailgun. I made this arrow pointing out which way the lid encloses. So it would be always same.
Then I used window seal gasket between the frame and the lid. 959
