How to make a 3-cylinder dust collector. NO.8 assembly 2 and NO.9 verification.

★ This is the final assembly of the unit.
・Install the upper chamber box and support bracket.
Proceed while checking the level and height.
・ The FB is a 3X12X156mm aluminum bar, and the receiver is a 5X15X40mm aluminum bar with a 4mm tap.
One place is a C-15X15 aluminum support material because it interferes with the VP30 from the lower chamber.
★ It has been almost two months since I started using the dust collector.
The viewer commented, "you made a long video, but aren't there any videos you are using !?" So I tried to verify whether the desired performance was exhibited and maintained.
★ Verification points
・ Is the initial ability maintained?
・ What is the degree of garbage sorting ability?
・ Presence or absence of points for improvement and improvement.
★ Consideration.
・ "Dust" with a light mass does not fall down, though not all. It seems that it will be sucked into the vacuum cleaner side while drifting.
・ Maintenance on the vacuum cleaner side is almost unnecessary. 1 pack / year? Or + a small amount seems to be sufficient.
・ It is better not to inhale long items such as drill scraps.
・ Since the pipe diameter is 25 mm, it is not possible to suck objects of a size close to that.
・ I think that the distribution of garbage is sufficient if the above is taken into consideration.
・ It is not necessary to check frequently, but it is better to go in about 2 months. (However, even in this situation, the suction power was not affected.)
・ The "garbage clogging sign" is strong and does not appear even if it is used. → It may come out if it gets clogged in the chamber in earnest.
・ The feeling of use is the same as when it started, and although it is a self-evaluation, it is good. Especially, the suction of dust on the desk was comfortable and the room was not dirty. → It is very effective for woodworking, puttingty and sandpaper.
・ If the vacuum cleaner to be connected is small, I think that one cylinder is enough without overdoing it. I had a 300w vacuum cleaner connected to the 1-cylinder (prototype), but it was quite comfortable. However, since it does not have the ability to collect soaring dust, a mask and appropriate measures were required.
・ It is the point of improvement and improvement, but it is the only "clogging". So far, it is necked by the pipe diameter of 25 mm of the unit used. → Even if you make the others larger, they will get stuck in the unit.
That was the consideration.
