@rocknroller912 asked me to provide some info on this design in the live feed chat.
I am planning on building a drum sander for my local hackspace (no point in doing it for myself as I have nowhere to put one, whereas at the hackspace we have space (especially if I also build a flip top trolley for it and the thickness planer we have), and a hefty extraction system.
This is the design I settled on, for a number of reasons (mostly covered in the video).
Planned changes from the original include
1) slightly wider (the belts I can find are wider, so why cut them down if we have space?)
2) motorize the belt (it shouldn't take much, I may have a suitable motor already, otherwise a stepper motor and speed controller aren't too expensive)
3) Sort out decent dust extraction
4) A better thickness adjuster (we have wood and metal lathes, milling machine, laser cutter and 3d printers, I think between those I can find a way to make a decent adjustment wheel)
I also think it should be possible to sort out a way to radius fingerboards on the top table.
For the moment this is all speculative since the hackspace is closed and also I need to find a suitable motor, but hopefully I can look at making it real before too long.

@jonhodgson I’ll be interested to see how you get on with this.
Do you recon you could make these @darrenking?
Make guitars, not war 🌍✌️🎸

I could certainly machine the plywood parts but I don't think I'd want to get involved in the assembly side of things. Manufacturing finished powered machinery involves a whole load of paperwork. Supplying kits of parts doesn't!

otherwise a stepper motor and speed controller
Industrial sewing machine motors are the future for home build machines. 1hp servo motor, controller and 'throttle' lever come in at around the £100 mark on ebay, with lower power version even less. Pretty much the same torque at all speeds, and very quiet!

@darrenking the bit of my post you qere quoting was referring to a motor just for the belt, so the sewing machine motor would be overkill I think.
As for the main motor, how powerful are these sewing machine motors? It seems this design needs 1.5hp to work well, a bit more if possible

I don't think anyone who isn't capable of putting one of these together from a set of correct parts should really be contemplating owning one.
Having the main parts accurately CNC'd would probably make life a lot easier, and also possibly improve the quality of the results.
a motor just for the belt
You get them down to about 350w so this would be pretty useful to drive the belt, better over powered than under. I have seen these motors listed at up to 1500w ie about 2hp but you may be better off just using a standard motor for the drum itself as you don't need speed control on this as well as on the belt.
@johhodgson
Thanks for the video. Wish I still lived in London, my town doesn’t have any shared facilities and local joiners hardly do wood work any more due to upvc doors and windows. It’s all house building from plywood kits.
Some people call me a tool, others are less complimentary. Tools being useful things.
@rocknroller912 I'm lucky at the moment because the London Hackspace is quite close to me (less than 25 minutes if there is no traffic), but its future in the current location is somewhat in doubt (the agreed rental period will be up before long) and I don't know where it will go. Before moving to Wembley they were in Hackney and there's no way I'm making that trek, especially as I tend to have a lot of stuff with me so public transport isn't viable.
There are some other options, but generally it would mean either having less facilities (other smaller hackspaces), or paying notably more but getting something very pro (Building Bloqs)
Looking forward to any community member making one of these and posting the result..I did see this or something similar on YT and thought I’d give it a go but I chickened out and bought a Jest 10-20 on casters..awesome in the shop.
I have too many guitars...said no one in the world..ever!

I like that one too and I really like Stumpy Nubs, I’ve learned a lot from that channel.
I think a motor is the only way to go as that hand crank is a bit underwhelming.
Good luck and looking forward to seeing what you come up with!
Practice on scrap...

This sounds really interesting, thanks for the tip I’m gonna check those out!

damn iPad corrective txt...JET.....
We’ve only just invented the wheel in Lancashire never mind a drum sander....

Jest, never heard of them. Oh wait, aren’t they from Lancashire? 🤔
@mattbeels 🤣🤣🤣🤣

this guy built it and he has CnC plans available i believe his is a bit wider that the original version.

Most of the other designs on YouTube don't have a belt, so it's already a step up, but motorizing it should be easy enough and would make it better I agree.
