- In this video I'm making a suction table for sanding small parts.
The measurements are 55cm x 70cm x 69mm
Made out of 18mm MDF and pine wood.

I made a box like this about half the size 30 years ago. it had a cork surface and I used it for sanding balsa wood. I found it worked best when I covered holes more than two away with sheets of paper.
Tim D thank you for the tips appreciate that. 👍
Well done! This is one of the best designed down draft tops I have seen. Tim D's suggestion of using paper to block-of surrounding holes is spot-on, from my own experiences. I also noticed a quite efficient-looking dust collector as well. I particularly liked the filter arrangement.
G Bruce thank you for your comment appreciate that!
I see one of these in my future, an excellent build. Even if the rounding of the holes didn't improve the airflow all that much, it certainly looks cool! Thanks for sharing.
Thank you Roberts! Have fun making one!
I cant tell if this works better than the one I made last night with twice as many holes but only 6mm sized holes. It does have suction holding the work piece down. Yours look way better that's for sure!
Nice video. Good to see someone else using a proper dust pan! (8:40) I can't stand the modern ones. Looks like a Toolstation special. I agree with the other comments regarding covering the area your not using but also, although this is a bit late, a sloping board inside the box. The slope goes up away from the extraction end. As you have it, only one end is really getting much suction. Good English by the way, hope you like it here.
Harvey Smith thank you very much for the support! Appreciate that!
The " sticky mat " material is the same stuff you can buy in Poundland, Home Bargains etc. and when it gets covered with sawdust and loses it's sticky put it in the washing machine and it comes out as good as new.
I'm enjoying your videos BTW.
Thomas McCusker thank you! Appreciate that!
You can most likely get another few percent better effeciency by turning the outlet port towards the floor.
You see where you attach the hose....take the screws out and turn that white plastic 4" port up side down so the dust can flow down wards rather than upwards, and then thru the 4" vacuun hose. I think it will help because you will be removing that bump, and the dust can flow freely into the hose without having to flow over an obstruction.
I think if you made the holes closer to each other with a smaller diameter (6 mm for example), you may get a better result. I am not really sure but this just came to my mind.
Thanks for sharing and wish you the best.
Turki Umairan it will be down to the overall surface area of the holes.if you make smaller holes but more of them may end up with the same surface area. And no change in performance!
Best would be to increase the volume of air moving trough the table with a stronger extraction unit! These things are all measurable! ( not my expertise though)
Love the design...great job!! Most guys make them way to big!
Rounding holes on bottom of top would produce better results and air flow. Still looks great.
That's very Cool Mate . I like that a lot.. I have quite a few sheets of MDF laying around. Thank you for sharing....Shared.
Thanks Terry. Much appreciated! 🙂
well done your ideas are great
Tony Gounden thank you
Nice simple solution to a common problem. Restricting the size of the table, as you did when rounding over the holes, would aid dust extraction.
I think I would still use a sticky mat under the work piece.
Thanks Kev. Sticky mat sounds like a good idea.
But don't know how sticky it would stay when it dusty?. Might try that.
This sort of thing, a couple of companies sell them.

+Kev Hwest thank you. That's a reasonably priced item, worth considering.
The dust that falls from clothing is horrific. I'm thinking of making one of these for when sorting laundry to keep the house dust down. Cheers!
Smaller holes would increase air velocity - paradoxically. Air velocity is what creates "Suck".. so smaller better. Venturi effect, blah blah. The first row of big holes are meeting the volume the extractor is capable of sucking, so the rest then, erm, "suck" at extracting.. smaller FTW.. You can buy pre-punched sheets of hardboard with small holes - saves a lot of mucking about with drills. :-)
Higher sides with a sheet that slants toward the collection port would improve it.
And how has the table worked out for you after a year of use? Great idea and I will be making one like that myself after seeing this
Best idea ever
maybe add some small walls around the table improve the dust collection. not in all sides. maybe in 3 sides
ottima idea...lo costruiro' anch'io 😉🖒🖒
Is something like this better than simply attacking a hose directly to the sander (where applicable)? I''m honestly curious because if it is, I would absolutely build one for myself.
Is the vacuum strong enough to suck all the dust out once it is in the box or does it leave some behind?
Nice work.
Trevor Whyatt thank you.
I believe it is strong enough to suck all the fine particles away. Possibly heavier ones fall to the bottom.
Obviously will depend on how good is your dust collector.
Szilard Pinter thank you. Adding it to my wish list.
Is the point of the table to aid extraction or to hold the piece securely or both? Would some sliding inserts that cut off flow to some of the holes allow for better hold down in the remaining area?
Hi. Thanks for commenting.
My only attention was extraction, not to worried about hold down or clamping for now.
Clean air comes first! 🙂
Smaller holes might have been better .. Put several good coats of Poly on it to help the particles slip into the holes and not remain on the top. Using paper or plastic to block holes on the outer edges should also increase its efficiency.
Clyde Decker thank you very much for the tips appreciate that!
Would there be better air flow with smaller holes?
Love the idea! Thanks! ... Could you tell me where you got the 4" adapter piece or was it 3D printed? If so, do you know where I can find the file for it?
nice! where did you source the adapter plate to connect the hose to it?
kspec2001 Toolstation.
Cool box but why glue the top surface? And why not add an inner panel in an angle for the dust to have less surface to travel to adapter?
Nice. You could have just bought a $15 4x8 piece of aluminum perf...but hey.
I think I've got the hole drilling part almost down . Could you show it one more time please ? Thanks
What’s a millimeter??
it’s the real way to measure.
@@tiouip took you long enough that was two bloody years ago
Add some dogs to the table to hold the work.
If u reduce the hole diameter u will get more suction
