The commercial machines have a very rigid bed (with a belt feed!) and the drum itself is pushed against the wood with regulated air pressure. They're usually a large belt going around 1 or 2 pressure rollers, and an idler roller. The bed moves up and down with a micrometer or digital display to adjust thickness. But, this machine probably costs about 1/100th as much as a commercial wide-belt sander, and does the job he needs quite well.
Made my first video today. I showed my version of the drum sander I made from your plans. Just a couple modifications for what I thought I wanted. Thanks Matthias.
I was looking for plans to build a drum sander and thought "who better to check with than Matthias?" Thanks to Pat for sharing his sander. And thanks to you for taking the time to create plans and share them for free on your website. You are the man! After the Christmas gift projects are completed (almost there) I'll have to decide what my next project will be. I'm leaning heavily towards one of the several projects plans I've purchased/acquired from you. I'm very excited.
Plans I have seen for a similar belt sander used a solid 3/4" shaft. They drilled a couple of small holes into the shaft a couple of disks in from each side. They put steel pins into these holes, extending out into the disks (cutting a space to fit them in two of the affected disks). I believe they used regular wood glue for the project. Gluing the pieces, putting the together, move the pieces around a bit, pull them apart and add more glue if much of it had soaked in.
Hey Matthias, I've been waiting for you to make one of these. I would love to see your version, you have a way with designing everything to make it work for everyone with great accuracy, I hope you consider it, it will just add to your already amazing collection of work :)
@thethethetheluis: Planers are for thickness. Sanders perform a dual function. Wood removal and smoothing. Planers snipe the ends, leave scratches, blades chip, etc. A good drum sander can do all that, but without the problems of a planer. Not to say that planers aren't useful; because they are. In my experience, a planer can remove a lot more wood at a time. Drum sanders, with an agressive enough paper, can remove wood, but nothing like a rotating blade.
Hi Matthias, do you cover somewhere how he attached the disks of MDF to the hollow shaft? Are they glued on with urethane glue or epoxy? Also, I assume the Velcro is held on to the disks with a PSA backing, I'm wondering if he put a finish on the MDF prior to adhering the Velcro? Thanks!
Does it often start tearing away from the leading point like that? I'm thinking a tab folded around the edge of the drum to a Velcro pad on the end could help reduce that.
Hi , you need to buy " velcro sandpaper " it's sandpaper that has allready a backing that will stick on the velcro. Once you have that kind of sandpaper , you'll easly sort out wich side of the adhesive velcro you bought will need to be on the drum.
Lmao! I clicked on it cause it looked interesting, then as I watched it I was thinking "Wandel would find this interesting" then I heard ur voice and realized this was in ur channel 😂😂😂
@slitor 1st; its 1 of his friends machine and 2nd; cuz most machines that do the tasks youd want cost alot or just dont exist because there would be a very strick market
One more question if you have the time. 5, Would a 2800rpm 3/4hp motor be better or would that be to much? According to a previous poster's maths that would give a surface RPM of 1465... Would it be advisable? Thanks in advance.
Pat's sander looks great! Would you yourself consider building another kind of sanding machine such as an oscillating spindel sander and releasing the plans for us to buy? I have not found the planes for a homemade spindel sander anywhere so far... Grüße aus Niedersachsen!
Your website article says the motor RPM is 1750 with 2" pulley on the motor and 5" on the drum. Am I calculating the RPM of the drum correctly? 1750 x 2/5 for a drum RPM of 700? With a 5" drum, surface FPM would be 700 x (5 x 3.14) then divide by 12 for ~915 FPM surface speed. This seems slower than commercial drum sanders (which really means nothing), but I wanted to make sure my calculations/formula is correct. Any help is greatly appreciated.
Is there an ideal speed for the drum to be spinning? I don't see any dimension's for the pulley on the drum. Thanks for the plans! I am almost there with my own build.
Video 6 years old, couldn't help but notice the standing pilot open combustion chamber gas water heater right there. it won't blow the roof off, but could make a 'boom.' I mean, the air has got to be really saturated with saw dust to blow the roof off, but just the right wisp of fine dust, flammable vapor or solvent to tickle the pilot flame.... also, the temperature and pressure relief valve just pipes to the basement floor? If that thing pops, buh-bye luthier's shop, hello wet basement. So much damage and injury that could be avoided.
Matthias Wandel, like I said, couldn't help but notice. I'm sure somewhere at some point a hobby shop caught fire from solvent vapor or dust and a pilot light. let me just make a few marks on my clipboard here.... Seriously, though, you are my favorite Canadian CZcamsr.
Use a sander like this instead of a planer for two reasons: 1) avoid damaging very thin wood like guitar tops, and 2) take very small amounts of material off per pass, because a guitar is a very delicate balance between thinness (for best tone) and structural integrity.
I've seen on several sites that the hook&loop expands slightly on diameter, due to centrifugal force when rotating. You wont need springs, the flexibility is in-built. The expansion on diameter is what gives the soft cut- you set it up to just touch the workpiece, switch on and the rotation does the rest. These machines take very small cuts, less than 10 thou' inch, just what you need for finishing boards in difficult timber.
That's why I am asking you... if someone on CZcams can come up with plans for that, it's you. Oscillating spindle sanders are quite pricey in Germany, like the small JET ones for about 600€.
Since he seemingly had a hand in creating the original Blackberry, I think you just may be right. (At least I think he said that in one of his Blackberry smashing videos)
Thanks for the video and plans, I'm making one and have a couple of (possibly stupid) questions that I'm struggling to find answers to if you don't mind. 1, Do you think a 19mm shaft will be ok? I know that means more truing but would it still be better than Pat's? 2, Would a 19mm shaft fit safely into 3/4" pillow blocks (0.05mm difference)? 3, Will a 1400rpm 3/4hp motor be ok? 4, Did pat give any rough indication as to how long it takes to get a 5mm board down to 2.5mm for example? Thanks!
How do you keep the table perfectly parallel to the drum? it seems to me that a single point table height adjustment mechanism would have to be perfectly centered on the table to prevent the table from flexing to one side or the other. I built mine with a two-point adjustment mechanism, one on each side of the table: czcams.com/video/cUi7_Ya9z-s/video.html
Im about to start building it. I need it for 3mm plywood sheets. Do you think I can get 3.00mm +-0.03 tolerance? Any ideas how to improve it for my purpose? Cheers

But, this machine probably costs about 1/100th as much as a commercial wide-belt sander, and does the job he needs quite well.
Pat mentioned that it's important to feed the stock at a consistent rate on the final pass to get a consistent finish.

Where does one acquire the sandpaper/velcro combination? What are these materials called?
Love this , this is the kind of thing you should try build because you haven't yet built a sander though a big percentage of wood working is sanding
Amazing. I built one and they could have been from the same plan. Great too for doing the thinner things the thicknesser can't.
Where can you acquire the hook and loop sandpaper for that purpose? I've seen it for orbital sanders, but not for sanding drums. Thanks!
For very thin stock, and difficult grain, a planer can make a real mess of it.
Hey Matthias, I've been waiting for you to make one of these. I would love to see your version, you have a way with designing everything to make it work for everyone with great accuracy, I hope you consider it, it will just add to your already amazing collection of work :)
Like the article says, I have no need for one so myself so I'm not planning on building one.

Has he made any guitars or ukeleles out of Norwegian Wood? :)
Fantastic build and good job of it, too. Thanks for the video Matthias and Pat.
Nothing on this drum sander needs to be changed in my opinion.
Ótimo projeto Senhor Wandel, parabéns
That makes sense. I don't tend to use difficult grain material. I've planed down to an 1/8" but that was with cypress.
Does this create a smooth enough surface for a glue joint?
I'm building one for maple tops.. planer shreds them.
Could you make a drum and cover for between the centres of your new lathe to make a similar tool?
I would also like to know where I could get the hook and loop sand paper.
Cheers
Correct. Commercial machines also have bigger motors.
Ending with one of my very favorite Beatles songs of all time - nice:)
Great, fantastic. Congrats!!!!
A lot like a surface grinder with metal… Brilliant!
I have a question.
Where to buy that sandpaper?
thats sweet. it looks like a big planer
Hey, this is a great project. Works very good. Do you know where can i find some of that velcro to wrap the drum with? I live in USA.
Hi Matthias, do you cover somewhere how he attached the disks of MDF to the hollow shaft? Are they glued on with urethane glue or epoxy? Also, I assume the Velcro is held on to the disks with a PSA backing, I'm wondering if he put a finish on the MDF prior to adhering the Velcro? Thanks!
@thethethetheluis for a guitar body you need really thin strips of wood which will likely disintegrate when fed through a planer
Pretty slick. I gotta make one of these sometime just for fun
Does it often start tearing away from the leading point like that? I'm thinking a tab folded around the edge of the drum to a Velcro pad on the end could help reduce that.
where to find rolls of velcro that match rolls or sandpaper??
what stops the wood from shooting threw fast from the rotation of the drum
Is there a reason to use the drum sander instead of getting a cheap but effective portable planer?
What did you use for the drum?
ok thanks Matias regards from Serbia
what is the strength of the engine and clicking rpm
Marvellous but where did you buy the drum?
Hi , you need to buy " velcro sandpaper " it's sandpaper that has allready a backing that will stick on the velcro.
Once you have that kind of sandpaper , you'll easly sort out wich side of the adhesive velcro you bought will need to be on the drum.
Very good job, excellent workmanship. I just finnish with mine.
@
VERY GOOD YOUR WORK!
so did you make the drum for the sandpaper? or purchase? if so. where from?
first thing I'd change is add on some feather boards to prevent the piece from flying across the room if I lost my grip....
Great audio by shopvac
The sandpaper comes with the 'loop' side already attached. Search for 'hook and loop sandpaper roll'.
just 1/2 HP on this one.
Lmao! I clicked on it cause it looked interesting, then as I watched it I was thinking "Wandel would find this interesting" then I heard ur voice and realized this was in ur channel 😂😂😂

Great video as always.
@slitor 1st; its 1 of his friends machine and 2nd; cuz most machines that do the tasks youd want cost alot or just dont exist because there would be a very strick market
get three drums, one for each of your sanding grits so its more simple to go from one to anther grit.
The same way as I have like 7 - 8 electric grinders, so I dont have to change disc all the time ;-)
For thin stock, one can use a planer sled.
One more question if you have the time.
5, Would a 2800rpm 3/4hp motor be better or would that be to much? According to a previous poster's maths that would give a surface RPM of 1465... Would it be advisable?
Thanks in advance.
i assume you are a luthier, this is good but do you know where i could get a ready built one>?

Dear Sir:
I would like to know how do you stick DM wheels to the shaft. Only by pressure and glue?
Thanks
me too. the plans don't say anything
You should make a design of your own with a rolling belt to slowly pull the wood in.
how thick shaft
is that belt slipping a little bit?
Need to make one of these but I don’t understand why the sander doesn’t grab the work and shoot it out. What prevents this from happening?
Thanks
Hager Hay it’s pushing the wood toward him.
What direction does the drum spin? Does it spin as to pull the workpiece in, or the opposite--to try to push against you feeding it? Thanks.
+matermark it rotates against the workpiece.
Your website article says the motor RPM is 1750 with 2" pulley on the motor and 5" on the drum. Am I calculating the RPM of the drum correctly? 1750 x 2/5 for a drum RPM of 700?

@Setobear: Amen
Boa noite! Sugiro que tenha legenda no vídeo!
thank you very much
The answer is just a google query away.
Is there an ideal speed for the drum to be spinning? I don't see any dimension's for the pulley on the drum.
Thanks for the plans! I am almost there with my own build.
Jack Earhart Depends on how you use it and how big your motor is.
That's because an oscillating spindle sander is relatively cheap to buy and very difficult to build. Just not worth it.
If i ever go about on mass producing end grain cutting baords, imm going to build one for myself! :)
Hi I liked the clip and wanted to know the dimensions of the wooden poly
Thank you

ever heard of a dust explosion in a hobby woodworking shop? Me neither.

thats what i need to make. any way to get the plans
Jimmy Meeker You could always look at the website linked in the description.
"Very difficult to build" Surprising statement considering the source .
i like this idea, if I make one I will put springs either side of the point of pivot so the table has a little give.. Thanks for posting
I've seen on several sites that the hook&loop expands slightly on diameter, due to centrifugal force when rotating. You wont need springs, the flexibility is in-built.

plz.. make a vid about ukulele building...
Since he seemingly had a hand in creating the original Blackberry, I think you just may be right. (At least I think he said that in one of his Blackberry smashing videos)
I would make the drum detachable and just have several drums with different grit paper for less hassle during change overs. Nice machine though!
Thanks for the video and plans, I'm making one and have a couple of (possibly stupid) questions that I'm struggling to find answers to if you don't mind.
1, Do you think a 19mm shaft will be ok? I know that means more truing but would it still be better than Pat's?
2, Would a 19mm shaft fit safely into 3/4" pillow blocks (0.05mm difference)?
3, Will a 1400rpm 3/4hp motor be ok?
4, Did pat give any rough indication as to how long it takes to get a 5mm board down to 2.5mm for example?
Thanks!
I LUV U MAN
why do you make all of your own things? just for fun?

Its something about Canucs and their Ukuleles...
you could put the platform the motor is resting on a hinge that weight the weigfht of the motor would always keep tension on the belt.
The motor will usually bounce if it isn't mounted solid.
No. Mines been running strong for like 5 years. They are pretty heavy. I'm probably like 200-300 knives on it plus some wood projects.
That thinks sounds like it extremely out of round.
Nothing. If you feed it in from the wrong side, it WILL shoot out.
Oh ya?
ok
PPE?
I still prefer my 15 inches timesaver... !
Search for the 'iWood' on 'stevinmarin' 's channel.
I'm the wrong person to ask. Sorry.
I bet he can create an iPod just from wood..
i could swear you said fuckin loop system lol
No way each one of those drums is 800. 80 dollars maybe... the entire contraption looks like it was made with less than 300 bucks.
