As a machinist with 48 years of milling, turning, grinding and hobbing experience, not many "shop made" things can actually impress me. This one though, is in a class of its own. I'm really impressed with your workmanship as well as the smoothness with which this sander runs. When you finish your plans, I will be ordering a set myself. Thank you for the inspiration.
I am not sure why! If you dont have a cnc, use a router it will just take a lot mor time. It's a very well thought out and executed design. I will be borrowing parts of it for mine.
I really want the plans to build this! This is the best homemade drum sander that I have seen. I have been trying think of how to build one. Please let all of know when the plans become available! Great job!
Could you tell me what you used to drive the wiper motor and control the speed? Some links to the parts used would be most helpful as well as any suggestions? thanks Jim
Hi, Haui... Thats a well built machine.. (event though, i by myself stopped building machines out of wood) You put a lot of effort into the project.. I am also planing, to build such a sander... Anyway..great job..subscribed and greets from Germany..
hello jorge , unfortunately the camera angle wasn't that good so most of the assembly steps was filming my back instead of filming the rollers assembly , thanks for your comment .
for the speed controller I used a PWM dc motor speed controller (10-55V 60A) with a 12V MEAN WELL power supply , do not use a cheap power supply it will not last because there is a lot of resistance when you use a fine sandpaper (150 grit or higher ) good luck
thank you , simply there are a headless M6 bolt with a strong spring underneath the aluminum angle on the left side , releasing the bolt will lift up the conveyor belt table and vise versa, it's the same technique that are used in the commercial machines.
thanks kstano83 , sure that a great feature since it fix the lines appearance issue but that will add up extra weight on the wooden structure which may ruin the main project , about the plan I did finish the cad drawing and honestly I don't know what to do next
@@OUUUUPS70 thank you for the reply, Is there any room to move it closer to achieve the ability to sand 3-in pieces? I am very interested in purchasing your design if you have it available in a kit or plans.
you are welcome , that could be achieved if you make the drum dimeter much smaller , in my case and according to the drawing there is no way to be that close . regards
Certainly one of the finer examples of workmanship I have seen in a drum sander build. I think I can closely reproduce your build with the insights you have shown with this build video but it is going to take some liberties on my part to get to the end point and I am sure it will vary from your build in some respects. I would be very interested in just how you configured the motor/drum elevator configuration part though. Any pointers on how you did that? Again my complements on a very nice piece of work indeed! Well thought out and nice structure and aesthetic as well.
first of all , I do really appreciate your comment , about the motor elevator on my drum sander it has the same exact concept that's the commercial one has , but mine build with a plywood instead of metal casting , the motor mount plate are running between tow grooves supported with a bearings from front and back to keep it sturdy and perpendicular to the conveyer table , and held with M10 rod and tow M10 nuts attached to the motor plate with a stiff spring between them to minimize the backlash, I hope that will help you , good luck james .
Hi I am attempting to make a drum sander, I notice most of the designs have small diameter rollers on the conveyor belt, is there a reason for this as they all seem to be 20-25mm diameter. I was thinking wider diameter more surface area, more friction and less slipping? What am I missing?
that's true , I did build a good sketchup model which I think it's not enough and it should be combined with a sheets of step by step descriptions and there where I honestly failed . thanks al
Shame.. it looks a fantastic project but seems that people are awaiting for plans. This could become very popular. If you have dimension sketch would appreciate it.
Haui is there anything other than the motor attachment to the vertical plate and the motor attachment to its base plate that holds that whole apparatus together and stiff enough to keep the shaft from undue stress? It seems like it would need something I do not see on the video and it would be helpful to know if my thinking is correct that I need to brace it further. Also I would be curious to hear what if any discoveries you may have found since putting the machine into use that might need an adjustment or change? Or has it met all of your expectations as you anticipated? As I said before it is quite a nice design and I am anxious to build one myself soon. thanks
hello james , I can assure you it's stiff enough and work just fine , it's moving up and down as one piece with no issue , but honestly not to be compared with a commercial one which is build out of cast iron , as a shop-build machine the results are good and meet my expectations. - the only thing I had discovered is there are a small amount of vibrations due to the drum sander balancing , so I had balanced it and minimize the vibration as minimum as possible.
@@OUUUUPS70 I had wondered what your experience had been and if you had found areas where you made adjustments to anything. I planned to use a Flexible 3-Piece L-Jaw Coupler Set & Rubber Spider between the motor shaft and the drum to allow some tolerance for any small misalignment inherent to the wood support structure. I do anticipate spending some extra effort to minimize any drum balance issues. I have seen other builds where there were various methods used accomplish this. I appreciate all the work you have put into this build and am so happy that I was able to find your build. I did switch in mid stream from another totally different plan to yours because of its open end design which I had given up on finding. Thanks for all your excellent work on this. Jim
@James Harris ,I do apologize for being too late to replay ,for some reason this comment did not appear on the notification icon , I just note it . yes i just use the same exact coupler , it helps a lot and reduce any load on the motor bearing if there is any miss alignment .

thank you I appreciate your words , to be honest I'm doing my best to make a good and useable plan for this build with no success yet .
@@OUUUUPS70
Would you like some help? I have friends who can draw everything and anything on CAD.
thank you for willing to help , I almost finished the drawing part
@@OUUUUPS70 so do you have plans ready now i want to make some drum sander fo rmyself and your project looks good
I am not sure why! If you dont have a cnc, use a router it will just take a lot mor time. It's a very well thought out and executed design. I will be borrowing parts of it for mine.
I loved your machine! Would you be so kind to share the measurements of it, please?
I really want the plans to build this! This is the best homemade drum sander that I have seen. I have been trying think of how to build one. Please let all of know when the plans become available! Great job!
I do appreciate your comment , hopefully it will be available as soon as possible
@@OUUUUPS70 Are the plans maybe already available somewhere by now? :)
I agree with the majority, very well done indeed. I am also interested in the plans when they are available.
thanks for your comment , and actually I don't know when this plan will be available
Could you tell me what you used to drive the wiper motor and control the speed? Some links to the parts used would be most helpful as well as any suggestions? thanks Jim
Are you going to make a set of plans available.
Hi thear can you plese showe a video of how did you do the lift part thanks in advance
Hi, Haui... Thats a well built machine.. (event though, i by myself stopped building machines out of wood) You put a lot of effort into the project.. I am also planing, to build such a sander... Anyway..great job..subscribed and greets from Germany..
Fantastic!
How much does it cost to build one?
only critique is you shouldnt be using mdf. eventually it will swell or warp if there's moisture in the air.
Hi Man great job love your approach to the drum sander.
I would also be kin on plans for your creation 😊
thanks Artur
I would like to purchase a set of plans as well 🙏
Very nice.! Possible to get plans for this?
Yes, soon
Very good job, do you have plans ready now, I`m interested in plans if they are finished.
Any progress on the plans?
Hello, congratulations for your work, the part of the system for raising and lowering the roller is not there, could you add it?
hello jorge , unfortunately the camera angle wasn't that good so most of the assembly steps was filming my back instead of filming the rollers assembly , thanks for your comment .
I see you used a wiper motor for the conveyor, what did you use for speed control and for 110/120vac to 12vdc transformer?
for the speed controller I used a PWM dc motor speed controller (10-55V 60A) with a 12V MEAN WELL power supply , do not use a cheap power supply it will not last because there is a lot of resistance when you use a fine sandpaper (150 grit or higher ) good luck
Really nice job! I coudnt understand the height adjustmant. Could u explain it?
thank you , simply there are a headless M6 bolt with a strong spring underneath the aluminum angle on the left side , releasing the bolt will lift up the conveyor belt table and vise versa, it's the same technique that are used in the commercial machines.
@@OUUUUPS70 thanks man
you are welcome
Great built. I’ll ask as everyone below, how can I buy the SketchUp file? Thanks
it's about to be ready , thanks
I wish it had oscillation feature but this is still the best DIY drum sander I´ve seen. How is making the plans going? I can´t wait to build this.
thanks kstano83 , sure that a great feature since it fix the lines appearance issue but that will add up extra weight on the wooden structure which may ruin the main project , about the plan I did finish the cad drawing and honestly I don't know what to do next
I like the pressure roller setup and how close it is to the drum. I am interested to know the minimum length of material that can be fed through.
the actual length between the rollers is 100 mm (4") , so I will not feed through any piece less than 110mm (4 3/8") to be on the safe side .
@@OUUUUPS70 thank you for the reply, Is there any room to move it closer to achieve the ability to sand 3-in pieces? I am very interested in purchasing your design if you have it available in a kit or plans.

@@OUUUUPS70 ok no problem, I can just use a sled for smaller stock. still interested, please message me when you get set up to sell plans/kit. thanks

knurling the drive roller will do the job , so there is no need to make them bigger

Hi Haui 👋🏻 great work, very impressed! When are plan’s available? Greets from Germany
hi, thanks for your comment , I m not sure yet .
Great job. Do you have plans available?
thanks Al , sorry there is no plan yet
@@OUUUUPS70 you could make more money if you had plans available. Something to think about. Good luck.

Shame.. it looks a fantastic project but seems that people are awaiting for plans. This could become very popular. If you have dimension sketch would appreciate it.
What kind of motor did you use for the feed conveyor? Where did you purchase it?
it's a DC 12v wiper motor 50rpm , i did purchase it from cars scrap yard , make sure it works fine before buying yours , good luck g m
Super szlifierka. Mam podobną. Pozdrawiam

Care to share the files for the CNC portion???
it's not ready to be shared yet .
This looks great! Do you have plans so I can buy it?
thanks for your comment , I'm working on it .
Nice one! How did you mount the motor to the drum sander?
thanks, it's attached direct to the sliding plate with three bolts and bolted down to an wooden mount which is attached to the same sliding plate.
Very impressed with your build and would love more info on ordering the set of plans. reguards
Fantastic build! What did you use for the conveyor belt?
thanks Wrate , two strips of 10" sandpaper roll (80 grit ) jointed with a cloth tape and CA glue .
Can u build Me the same machine ?
sorry , I can't
bravo pozdravim
U can bild the same for me ,and i bought it !!!
thanks stephan for your comment , I don't think that is possible but I encourage you to build your own sander .
