One of the biggest disadvantages of this hobby of carpentry is that when we sand wood, a huge amount of sawdust dust is generated that ends up floating in the air, depositing itself everywhere, and what is worse, it can go directly to our lungs
And if we use a sanding machine, such as the drum sander From the drill press, the amount of sawdust dust is even greater than by hand sanding, and the machine expels it into the air with more force.
It is always advisable to use a mask when sanding wood, but for the specific case of the sanding drum, we see in the video how easy it is to make a vacuum system, which captures practically all the sawdust dust that is generated.
Making this sanding table for the drill press is quite easy if we have some crown bits. And, perhaps the most complicated part, is to give a little shape to the hole into which the suction tube enters, so that the air with the sawdust dust flows without turbulence.
The ring inside the vacuum system is also important, since it serves to fit the bearing of the sanding drum. It also gets wider towards the bottom, because I think that can help direct the powder out of the ring.
The gap in the surface of the sanding table is only slightly wider than the diameter of the sanding drum. Just enough for air to flow easily but forcefully into the interior. And on the inside I milled a bevel that I hope will help reduce turbulence.
The final surprise was seeing how well this vacuum system works. And you can see in the video the enormous difference between connecting the vacuum cleaner and not connecting it. When I used this sanding drum, before I always left the work table in a mess and could see all the dust from the sawdust floating in the air. Instead now I can sand wood with the peace of mind that all the dust is going to go into the sanding table, through the suction tube, and into the shop vacuum.
