Introduction: Drill Press Dust Collector & Laser Guide
In this instructable/video, I will be making a dust collection system and a laser guide to reduce the mess you get after the drilling and improve drilling accuracy. These accessories are pretty simple to make and they are very nice to have.

Step 2: Making the Dust Collector
First, I cut all main pieces for the dust collector.
The gap between stacked pieces should be the same (or slightly narrower) as the diameter of the drill press pipe. It is unlikely that you will get it right just by stacking pieces, so we need to trim one piece with a router.
I marked the middle of each piece and used spade bits to get the right diameter holes. You can use forstner or hole saw bits. Use what you are most comfortable with. Sizes, of course, will depend on your shop vac hose adapter. In my case inside diameter was 25mm and outside 35mm.
I glued the pieces in three parts - middle, left and right. I am not gluing all parts together yet as I will need to drill and sand the middle part.
To make the hole into the middle part, at first, I tried using the same 35mm spade bit, but quickly gave up as the bit kept stucking while drilling. I tried avoiding drilling bigger holes on the drill press until I had this dust collector, as keeping everything clean is important for my tiny work corner.
For sanding inside a rotary tool like Dremel or similar, it will make this easy and quick.
Now we can finally glue all three parts together.
When I placed the collector on the drill press I glued additional support blocks. If your drill press doesn't disassemble easily secure the parts with few screws as we will need to take of this piece later.
Now at both ends, we need to drill holes for the long screw.
I tightened screw with a nut, and on the end I used a wing nut. Very simple and very effective.
The results are day and night! If you care about not making a mess, something like this is must to have!
Step 11: Making the Laser Guide
For the laser guide, first we need to make some sort of holders for the lasers. The most important thing here is that the laser had a snug fit to the 12mm hole. I used a spade bit, but if you have a 12mm forstner bit, you definitely want to use that.
Next, nothing really special, we just need two square blocks, drill pilot holes in each of them and then fix that laser holder on a square plywood block by drilling more pilot holes and adding a screw.
With two holders done, I made a base that will hold those two parts. Like the dust collector, it will go on the drill press post.
But before attaching the holders, now is the time to add all electronics and other parts. As at the top of my drill press post is a huge motor that is very close to the pipe, I just attached a zip tie instead of making a proper clamp as I made on the dust collector.
I fixed the power switch with a tiny part of plastic and the battery holder with thick double side tape and one screw in the middle.
To power this project you will need one lithium-ion 18650 battery and the TP4056 charging chip for it.
BE AWARE! There are protected and unprotected 18650 batteries:
- if you use a protected battery, you can use the TP4056 chip (like I did)
- if you use an unprotected battery, you MUST use the TP4056A chip (bigger chip)
We also will need few line lasers. When powered two of them consume only ~30mA! So even with a very low capacity 18650 battery, like 1000mAh, you will get ~30 hours of usage.
By rotating the end cap you can adjust the optic and it will give you a thin line. Too bad that the rotating optic is kinda loose. So to prevent it from rotating accidentally we need to stretch the spring.
To fix the lasers in place I used small screws. Remember that screw pushes the laser to hold it in place. So if the hole will be too loose you will have a bad time when adjusting the laser lines.
And now - soldering. This is very basic stuff:
- The positive wire from the battery goes to the outside contact of the switch.
- The positive wires from the lasers go to the middle contact of the switch.
- All negative contacts are connected together.
- The positive wire from the charging chip goes to the positive contact of the battery (which is on the outside of the switch).
And you are done with the soldering!
To charge it you use a standard 5V micro USB charger, or you can get that chip with a USB Type-C connector.
Finally, we need to secure the laser guide to the drill press and we are done with the build!
What's left is to align the lasers. I aligned them the hard way (1-5 picture), but there is a simple way. Basically, both laser line planes must go vertically through the center of the drill bit. In simple words, insert a very long bit into the chuck and adjust that the laser lines from both sides would be right in the middle of the bit (last image). Of course, you should use any perfectly straight and long rod or drill bit and not a pencil, it is only for demonstration purposes.
Step 22: END
When aligned, you will get really good results!
