More 3D printed tooling. Table saw for PCB cutting. Nice!

Ya está casi completa mi mesa de sierra circular para cortar PCB’s u otros materiales. El coste del BOM: ±10 €
Code name: “Shadow Saw”
A vacuum attachment would be nice. Fiberglass dust is nasty.
Very cool! I have to try and make one!
Thats a great idea, Urm however I would suggest some guide rail, and maybe possibly add some protective cover
please don’t use it for cutting PCBs. Glass particle that are the dust that forms from such cutting is very light, stays in the air long and, once it gets into your lungs, never leaves. Very bad for your health. It is recommended to protect yourself during such operations and, best of all, make sure the dust does not fly - best to cover the working area with water, as you can see in youtube vids about PCB milling…
Come to think of it, you can adapt this setup to PCB milling by turning the whole thing upside-down: put motor above table, cover table with water, separate morot and electronics from saw by a waterproof case. PCB moves (floats :)) underneath, gets cut, no dust.
@Jelle_Boomstra sorry to be late with the reply on this but here is what I can tell you:
Unfortunately, can’t provide you any documentary proof. Maybe in Russian but I don’t think it’d be any good. Your question made me leaf through quite a lot of bureaucratese in search for specific indications as to why this dust is harmful. That it is harmful I have known for ever - having heard it on a gazillion of workplace security lectures.
So, the idea behind it is that 1) glass forms fine dust that 2) gets into lungs and 3) sorta stays there. This is not harmful in a way cretain types of asbestos are (not carcinogenic). But 4) if accumulated in lungs it can lead to a glass-derived form of pretty bad lung disease that is also knowm among coal miners (in their case it’s coal dust of course) and construction workers (cement dust there) and others. So, if you are cutting a PCB once a month - go ahead, be my guest. But I would not recommend it on a regular basis.
