Simple and elegant, yet very functional. I've seen some shop made drum sanders on here that are way over complicated and over engineered and don't work well at all. Plus they're rickety and cumbersome. Well done man.
I keep watching this video over and over. It seems like the simplest and well thought out. I plan to build one in the near future and plan to incorporate most of your methods. I especially like the feed roller mechanism and the hold down springs. I definitely want to use the four post and chain lift mechanism. Thank you so much for posting this video.
Your very welcome Joe! I would suggest using thicker all-thread for the four chain lift mechanism. I think I used 1/2 inch and it does flex and the sprocket slip sometimes when im cranking on it too hard. This could be avoided if you keep the sprocket and chain closer to the lower frame instead of the middle of the all-thread (keeps flexing to a minimum) good luck on your build!
best home made design i have ever seen for a home made drum sander! i particularly like the depth adjustment great design! But i have a suggestion coming from experience with an industrial 3 phase version on the first and last 6 inches or so of the workpiece you can hear the sander taking a little more off this is because the infeed and outfeed rollers allow the piece to pivot and the drum bites a little deeper than the middle if you get me? i would put 2 infeed and outfeed rollers on either side of the drum to prevent this so the workpiece cannot bow upwards into the drum. let me know what you think
+Thomas Doherty Thanks for the suggestion. So if im understanding you correctly, 4 rollers instead of just the two. That way there's always at least 2 points of contact with the work piece, thus minimizing/ eliminating
Where did you get you gears from? What diameter is your drum? Where did you get your hook Velcro to go on the drum? How did you make the crank handle to raise and lower the table? How long are your 5/8" all tread rods? This is the best home made drum sander I have seen on You Tube!! Thanks, Dan email:dan@wemorph.com
Do you have plans for this available?? I have been looking for a while trying to find the drum sander I liked the most, and so far, this is looking like I want it in my workshop.
I got to tell you that i loved the table riser and how it worked. Admittedly, I have been trying a similar lift mechanism but failed. I see now that i made the threaded rods too short. Since seeing your video, I think I will revive my drum sander build. Thanks!
+Terry Evans that's great. Im Glad the vid helped. Good luck on your build. I I would suggest not going too long with the threaded rods because the 1/2" threaded rods that I got does bow (flex) some if I'm too aggressive with the crank, and sometimes cause the homemade sprockets to skip.
+Mike Kling My thoughts exactly. I Needed a 24" drum sander to thickness guitar top, back and sides. Building it myself didn't cost a lot of money... Just lots of time and patience. I still gotta build the dust shroud and belt guard. I'll post it once it's completed.
Wow! This is the most unique homemade drum sander I have ever seen. How difficult would it be to attach a hood over your creation to suck up the dust? Overall you made one hell of a drum sander. The time it took to design and implement it definitely paid off. It truly is a very useful tool. After seeing your drum sander any other design on RUclips is just a joke. If you were to get someone to blueprint your design you could sell the design online. I’d buy one without a doubt. I am going to subscribe to your channel In hopes that you may have your design printed. How difficult would it be to attach a hood over the drums to pick up the dust? Thank you for sharing it on RUclips.
Im building a 33 inch belt sander right now, but this might be next on the list. Definately an excellent build :) Nice to see what luthiers are building for themselves.
+watahyahknow Glad you like it.. I made the sprockets myself, so they have a bit of variance in tolerance that causes it to slip if I'm too aggressive with turning it. Good luck on your build.
Thank you so much for taking the time to upload this video. It truly is ingenious. Especially the pinch roller springs and the feed. Not to mention the 4 corner table lift. Do you have any suggestions on building the table so it will not warp due to temperature and humidity changes?
Your very welcome, I've got a lot of video clips of my guitar build but haven't had time to edit them (mostly procrastination) thank you for giving me that nudge. As to the table I do get some vibration and slight warping now that you mention it, mainly due to using a cheap hollow Ikea end table. In hindsight 3 layers of birch plywood with formica laminated on top would of been ideal. Oh.. and bind the edges wouldn't hurt.
Love your design. I have seen many of these machines made and yours is a winner. I want to make one! Have you thought about adding a gear reduction motor to the feed instead of the hand crank?
I know I’m 2-1/2 years late but found this to be an excellent example for what I want to build. May I ask how thick material can you pass through? On a suggested note perhaps use a small electric motor for advancing the material through For sprockets get some small fixed wheel ones from a bicycle shop and either enlarge the holes or down size the thread bar. Love this design brother very well done 👍
I normally find most RUclips shop made/home made drum sanders almost laughable , that is if they weren't so dangerous looking... but in this case, I think you did a real nice job with it and it looks like it could easily be expanded on ! Look for an old treadmill that you wouldn't mind repurposing then retrofit the motorized tread/belt into a conveyer table for your sander.
Excellent build! You may want to look into having a conveyor belt on the bottom to put your work through it. Use an old treadmill, they go used for like $25 around here and they've got an unbelievable amount of power with variable speed.
Nice well thought out build. Probably makes a mess and a lot of dust but these problems could also be fixed down the road. I like the furnace Blower motor idea. Thats about a 3/4 horse motor it dosn't take much power to run somthing. A few guards for the belts and hood for the drum to collect dust and its as good as a new one sort of. Hey if it works find something elses you need to buy first.
Did you just make the disks fit snug to the through rod, or did you have to do anything else to keep the rod from spinning inside the drum when the paper meets resistance?
Great Job!! I really like your table adjustment and your infeed design. I was wondering if it might be better to have the table be fixed and raise or lower the drum? Maybe using your threaded rod to just move the roller. This would allow for a fixed infeed that would ride up and down as the drum was positioned. I am also considering the tilted table as others have incorporated in their DIY drum sanders. Thanks for the Video!
+John Giannuzzi Thanks!..if the table was fix and height adjustments was the on drum... Wouldn't the motor, pulleys, belt and rollers have to be able to move with the drum in tandem? I might not be understanding it the way you got it pictured in your mind.
Vincenzo, sorry I don't have any extra picture and unfortunately the sander is in storage at the moment. Was there something in particular about the feeder system that you want clarification on?
@@nguyenkhai1 Hi, thanks for reply. I would like to know if the bolts that the springs slide on are screwed and how you calculated the height of the rollers to be two millimeters below the drum.
@@vincenzogiacalone the 4 bolt that the spring slides on are screwed into the bottom of the frame (i tapped some threads in the frame first). These bolts hold up the entire roller feed assembly. I get the 2 mm adjustment by backing out the bolt which causes the whole roller assembly to drop or tightening the bolts which causes the whole assembly to rise (i did this on all 4 bolts as evenly as i could). I say 2mm but it's just an estimate.. as long as the rollers are lower then the drum then it would be the first to contact the work piece. Which makes advancing the work piece possible. If the rollers were higher then the drum then it would be just merely decoration... Lol
Great design of your sander. I love the velcro attachment. may of them have clips that let go or break! nice work on it!! That looks like a dishwasher motor...i have on just like it!!
Hey. I love the sander, and am in the planning stages of building one of my own. I had some questions about the height adjustment mechanism. Where did you get those little sprockets? Is the only thing holding them in place the 2 nuts? Where does the allthread go? I can see it goes through the table support piece with the welded nut. Does it go into the top and bottom of the frame or not? I'm having trouble getting my mind around how exactly it works.
+marathonholloway sorry for the late reply.. just getting back from a 10 day cruise. I had made the sprockets out of two fender washers that I welded together and the teeth shaped with a rat tail file. Sprockets are held in place with just friction from the top and bottom nuts jammed together. The all tread extends all the way through the bottom of the frame and halfway through the top of the frame.There is a hidden nut that's welded to a fender washer and attached to the bottom of the table supports (the nut is recessed into the bottom of the table support.) All of the sprockets are at the same height and is fixed to the all thread and turns as a single unit. The chain allows for all 4 of the all thread/sprockets to turn the correct amount in relation to the others. When I turn one corner.. all for corners turn the same amount thus raising or lowering the table support and in turn raising or lowering the table. I hope that makes sense.
Great video, Khai! I do have a few questions: 1) is that little cylinder next to the motor (with the black and white wires coming out of it) the capacitor? 2.) Where did you get the feed rollers? If they're wooden dowels, I'd think they wouldn't be stable enough to stay straight. 3.) those sprockets at the end of the feed rollers and the feed wheel itself ... are they common bicycle parts, or did you get them elsewhere? Thanks in advance for your help.
Hey John, 1) yeah it's a capacitor.. i don't know what type, rating etc.. it came out of an old AC unit and was already attached when my brother gave it to me. 2) the feed rollers are 5/8 water hardened drill rods wrapped with PSA sand paper. 3) the sprockets I think I got from. Fastenal (.com)
Hi Khai, what type of glue did you use to glue the disks to the shaft? I am building a drum sander now and have seen many people use variations of a set screw to secure the drum to the shaft so that it doesn't spin while on the shaft. Any thoughts on using glue versus set screws? Excellent work!
+Pod Luthier I used guerilla glue (disc to shaft) and titebond original (disc to disc) I also drill a hole through the shaft between the second to last disc on either end in which I added a roll pin sandwiched between the second and last disc. in my opinion the glue by it self would of been enough. The pins were overkill. Set screws could be an option but it would require quite a few of them to be effective and they are an additional cost. When you rough up the shaft and use the guerilla glue there is so much more surface area holding the discs on vs just a set screws at a certain point. Just my thoughts...
Hi Khai, thank you very much for your quick response and for providing these great insights! What you are saying makes complete sense. I would imagine that a big drum would have a difficult time spinning freely on a shaft with a good tight fit, but, as you know, with the time invested into building this thing correctly, one wants to take all the right precautions. I think I will do something similar to what you have done. My concern (though I am certainly no mechanical engineer, or even an engineer, for that matter) would be that removing material from the shaft to insert too many pins or set screws might actually compromise the straightness and strength of the shaft. Thank you very much for your help and, again, great work. Thanks for sharing your awesome project on RUclips.
+Pod Luthier well put.. just the two holes I drilled for the pins had me worried about the shaft flexing in those spots.. in hindsight. I'd just go with glue. Just hit the shaft with some 80grit first. Good luck on you build!
That is a really awesome machine. I have two questions. Maybe you addressed this but I missed it. What are the feed rollers covered with? Is it just more sandpaper to give it grip on the wood? Also, have you considered building a hood so you can get some dust collection working? I have a small Byrnes thickness sander (6" wide drum) that if I didn't hook up my shop vac to it my shop would be covered in sawdust in no time. Your machine removes a lot more wood than my Byrnes.
+Fuzzy Johnson you are correct! The rollers are covered in 220 PSA sandpaper roll and it's for grip. The dust collection hood and a belt guard will definitely be in a future video. This sander produces very fine dust... Tons of it! In a very short time. Not only that but the feed rollers get caked in dust and looses their grip if I don't blast the dust off with compressed air. Thanks for watching.. Happy Thanksgiving!
Great build and thanks for sharing. I'm building something similar. Did you just use common adhesive back velcro from the hardware store or something supplied specifically for this purpose?
Hey man, great project! So have you since added the dust cover, etc.? Also, does it have the same issue of snape that a planer would? Just love this design and the height adjuster.
Thanks, I didn't get around to building the dust cover. As to the snape.. I only take about 1/32 -1/16 at a time. Also by having the feed roller on top pushing down.. I haven't had issue with snape.
Real interesting machine... I came across this video looking for ideas on how to build my own drum sander. I know it would depend a lot on what types of material you are sanding, but how often would you say you have to change out the sand paper? Do you have a preference on what brand sand paper?
+Schweet119 I have yet to Change the paper. It's some cheap stuff I found on eBay. To my surprise its still going, and the Velcro is still tight! Hasn't came off ...yet..
Could you explain a little bit more about the table top, did you build that as a torsion box? I would think that would need to be really stiff to stop it from flexing when you are sanding pieces of material in the centre of the sander? Also, would it not work better if the springs that creates the downward force in the drive drums were stronger, it looked like they were slipping a bit when you ran it at the end of the video? Otherwise the sander looks very stuff and sturdy, well done! :-)
+Morten Mortensen the table top is an old IKEA end table I had laying around (there is some degree of flex), ideally should of uses at least two layers of plywood with melamine glued to it. As with the springs you could always go bigger, but with the weight of the feed roller assembly along with the 4 spring it seems to be sufficient. The way I had designed it I could easily add more downward pressure just by tighting up the retainer spring screw, the downside being... that it might deflect the cheap IKEA table even more! Thanks for watching.. good luck on your build and post a video of it.
+Greg Schlierf +kame Singh had commented that he recently used these ideas to build his own sander and it came out good! Good luck on your build... Oh.. If yours come out better than mines, let me know what improvements you've made to it. Cheers!
the feed is well thought out. It would not be hard to power it up by using a garage door opener motor. The come with plenty of chain, and of course the sprockets, and are all ready geared down to the right speed. I have found lots of uses for them. les

I was looking at a second hand drum sander and it's like £800 - £1000 so I'm pleased to see there is a high quality diy option thank you for sharing 👍
Only one word to say. "Genius" Thanks.
That has to be the best table I have seen on youtube. You’re execution and planning are superb.
That is the best homemade thickness sander I have seen. Great ideas for both the table adjustment and the sprung roller system.
The best sander I've ever seen. Congrats and thank you for sharing. Ricardo, from Brazil.

+Terry Evans 3/4 seems like it'll be rock solid.
If it turns out half as good as yours, I'll be happy! Thanks again!
Also, larger diameter sprockets would not slip as easily.
Parabéns! O melhor projeto que já vi, vou tentar fazer um desse.
Good sander you came up with. I was wondering how thick a guitar back and tops are. I am in the process of building a square neck resonator.
That height adjustment system is insane
I mean, it's not terribly complicated, it's just so clever enough not seen anything like that
Excellent. Like you I really want a drum sander, but can't justify spending $1200+ on a 24" sander. Now I have an example to follow.
+Mike Kling My thoughts exactly. I Needed a 24" drum sander to thickness guitar top, back and sides. Building it myself didn't cost a lot of money... Just lots of time and patience. I still gotta build the dust shroud and belt guard. I'll post it once it's completed.

Very good design, just what I was looking for, thanks!
Very nice. One of the best setups I’ve seen
That is very impressive. You should be proud of yourself.

Thanks Craig! Lots of hours put into it.
The manual top feed system (with the springs) is quite clever! I might just opt for that. Thanks for sharing!
+wintersnot your very welcome. Good luck on your build!

Thank you so much! for such kind words. if my kids are inherite it, I'd better get going with the safety drum shroud. ;)
Best homemade design...2 side moving rods are awesome!!!! Good Job Khai !
Thank you, excellent design, with great care in details!!!

Did you just make the disks fit snug to the through rod, or did you have to do anything else to keep the rod from spinning inside the drum when the paper meets resistance?
Great design re the chain driven height adjuster and spring tensioned feed drums. Also using pipe for the sanding drum. 👍👍👍😎
+John Grant thanks for watching.

like the way you added the disk sander to the motor
Would have been better at the end of the Drum sander rod, so you are not laying on the floor to work.

Thanks Raymond! It was fun to build and very satisfying to use.
if this idea is your own, I must to say congrajulation to you. you are the intelligent guy. thank you for shearing this brilliant idea. Mercy man....
what did you use on the feed rollers to grip the material, looks like sand paper.
+Allan Chapman it's 220 PSA 4 1/2" sandpaper. Let me know if any you got any other questions.Thanks for watching!
hi Khai Do you have plans for the sander???
Excellent design and execution of engineering principles. You have a gift for solving practical problems. Plans? Many thanks for sharing.
Your welcome, glad you enjoyed it. Hopefully it will inspire others to make their own.

Great build, gotta be really smart to figure all that out. Quick question though, why not motorize that hand crank?
I just didn't have a motor suitable for the job. I think a treadmill motor would work though. Low rpm but high torque.

1) yeah it's a capacitor.. i don't know what type, rating etc.. it came out of an old AC unit and was already attached when my brother gave it to me.
2) the feed rollers are 5/8 water hardened drill rods wrapped with PSA sand paper.
3) the sprockets I think I got from. Fastenal (.com)
@@nguyenkhai1 Thanks! If you have a source for those drill rods, let me know. But I have some ideas on how to make the rollers myself.
Hi Khai, what type of glue did you use to glue the disks to the shaft? I am building a drum sander now and have seen many people use variations of a set screw to secure the drum to the shaft so that it doesn't spin while on the shaft. Any thoughts on using glue versus set screws? Excellent work!
+Pod Luthier I used guerilla glue (disc to shaft) and titebond original (disc to disc) I also drill a hole through the shaft between the second to last disc on either end in which I added a roll pin sandwiched between the second and last disc. in my opinion the glue by it self would of been enough. The pins were overkill. Set screws could be an option but it would require quite a few of them to be effective and they are an additional cost. When you rough up the shaft and use the guerilla glue there is so much more surface area holding the discs on vs just a set screws at a certain point. Just my thoughts...
Hi Khai, thank you very much for your quick response and for providing these great insights! What you are saying makes complete sense. I would imagine that a big drum would have a difficult time spinning freely on a shaft with a good tight fit, but, as you know, with the time invested into building this thing correctly, one wants to take all the right precautions. I think I will do something similar to what you have done. My concern (though I am certainly no mechanical engineer, or even an engineer, for that matter) would be that removing material from the shaft to insert too many pins or set screws might actually compromise the straightness and strength of the shaft. Thank you very much for your help and, again, great work. Thanks for sharing your awesome project on RUclips.
+Pod Luthier well put.. just the two holes I drilled for the pins had me worried about the shaft flexing in those spots.. in hindsight. I'd just go with glue. Just hit the shaft with some 80grit first. Good luck on you build!
That is a really awesome machine.
I have two questions. Maybe you addressed this but I missed it.
What are the feed rollers covered with? Is it just more sandpaper to give it grip on the wood?
Also, have you considered building a hood so you can get some dust collection working? I have a small Byrnes thickness sander (6" wide drum) that if I didn't hook up my shop vac to it my shop would be covered in sawdust in no time.
Your machine removes a lot more wood than my Byrnes.
+Fuzzy Johnson you are correct! The rollers are covered in 220 PSA sandpaper roll and it's for grip. The dust collection hood and a belt guard will definitely be in a future video. This sander produces very fine dust... Tons of it! In a very short time. Not only that but the feed rollers get caked in dust and looses their grip if I don't blast the dust off with compressed air. Thanks for watching.. Happy Thanksgiving!
Great build and thanks for sharing. I'm building something similar. Did you just use common adhesive back velcro from the hardware store or something supplied specifically for this purpose?
Thanks for watching Zax, I used regular Velcro brand I think 2" wide. Just the hook side, the sandpaper roll had the loop backing.
innovative
Super cool Khai.
Thanks! Niel.. it's amazing how necessities can drive you create something pretty cool out of scraps.
muy bien hecho amigo
I love it! Congratulations and thanks for sharing!
Thanks again. I'll be watching your videos.
Hey man, great project! So have you since added the dust cover, etc.?
Also, does it have the same issue of snape that a planer would?
Just love this design and the height adjuster.
Thanks, I didn't get around to building the dust cover. As to the snape.. I only take about 1/32 -1/16 at a time. Also by having the feed roller on top pushing down.. I haven't had issue with snape.
@@nguyenkhai1 Thanks for the reply on a video you made 4 years ago!!! Have a great day man!!!
What horsepower is your motor? Thanks!
👍👍👏👏excellent build.
Real interesting machine... I came across this video looking for ideas on how to build my own drum sander. I know it would depend a lot on what types of material you are sanding, but how often would you say you have to change out the sand paper? Do you have a preference on what brand sand paper?
+Schweet119 I have yet to Change the paper. It's some cheap stuff I found on eBay. To my surprise its still going, and the Velcro is still tight! Hasn't came off ...yet..
nice build i got to give you credit you did a great job
Thanks 😊
Olá boa tarde, que material voce colou nesses dois rolete para puxar o material a ser lixado
Could you explain a little bit more about the table top, did you build that as a torsion box? I would think that would need to be really stiff to stop it from flexing when you are sanding pieces of material in the centre of the sander?
Also, would it not work better if the springs that creates the downward force in the drive drums were stronger, it looked like they were slipping a bit when you ran it at the end of the video?
Otherwise the sander looks very stuff and sturdy, well done! :-)
+Morten Mortensen the table top is an old IKEA end table I had laying around (there is some degree of flex), ideally should of uses at least two layers of plywood with melamine glued to it. As with the springs you could always go bigger, but with the weight of the feed roller assembly along with the 4 spring it seems to be sufficient. The way I had designed it I could easily add more downward pressure just by tighting up the retainer spring screw, the downside being... that it might deflect the cheap IKEA table even more!
Thanks for watching.. good luck on your build and post a video of it.
Amazing.
With so much exposed, you should consider building a cover to protect yourself from the sander and chain. Good job on the build.
+BigBravesFan Thanks! Your right.... Cover/shroud project has been long overdue.
this is a great build. I need one about that size and just can't justify 3000 for it. You may have given me a project !
+Greg Schlierf +kame Singh had commented that he recently used these ideas to build his own sander and it came out good! Good luck on your build... Oh.. If yours come out better than mines, let me know what improvements you've made to it. Cheers!
Will do for sure.
Sugiero hacerle una caja de protección donde estén las bandas
Outstanding job , thanks for sharing .
thank you great build kudos to you
Thanks for watching Walter!
Wow nice job! You put a lot of thought into it for sure
Good start but I'd make some changes some cover for dust collecting
+Mark Schuster I've bought the parts for a dust collector build, just haven't got around to building it yet.
the feed is well thought out. It would not be hard to power it up by using a garage door opener motor. The come with plenty of chain, and of course the sprockets, and are all ready geared down to the right speed. I have found lots of uses for them. les
+les wheeler that's a really good idea. I've got an old 1/2 hp garage door opener motor too.
Very cool! !!
