Thanks for the prompt reply Harry72, that's cleared that up for me. I's thinking of making one with a steel drum, say 115mm dia. I have access to a lathe and materials. How do you think that will go?

Should be ok, mine has a 5" drum(ally extrusion)which IMHO is to light weight, a heavy drum would act like a flywheel smoothing out vibration somewhat.
You'll need a 4 pole motor, or gear/belt and pulley reduction to obtain about 1400rpm of the drum and with good torque. It would be easy to overheat the abrasive/wood gums with higher rpm's... dont use it on pine you'll kill the abrasive every time!....................................................................

Thank you for suggestion! For the moment, I have not any dust extraction system at my shop But my first acquisition will be a high-power and mobile dust collector (capacity 2000 m3/h, inlet diameter 1 x 130 / 2 x 100 mm) that help to keep the working area free from chips and dust.
Regards,Lucian

Great job so far
I liked the way you can adjust the back side of the table down for thicker stock. My first and secound one was not adjustable. My thrid one is adjustable but with my dust hood being just like yours, I lose the vacume because the gap on the back side of the hood and table is so wide. I placed some 2 inch rubber weather striping on the back now to take up that space, and it helps hold down really thin stock as well.
Love to see some Video of that thing when finishedJunkBoy999

hello guys
i have been reading all of the replys that you all have been making on the drum sanders,i have been wanting to build one for a while but wasnt to sure of how to make the drum till i came across this forum and seen the one that lucian built.the one i am building has two drums and infeed/outfeed rollers,i felt that that would be the best for me since i have limited use of my left arm.i will try to leave some pictures if i can figure out how to use this forum,lol.i will also get the details of the equipmet that i have used so that i can get you guys back feed on what you think and any sugestions that you may have.i have a raise/lower handel on each end that i use to adjust the height and keep the table level with the drums.it worked good when i was sanding the drums down useing the board with the sand paper to smooth the drums down,ended up with a drum that was 5 5/8 across x 25 1/2 inches long.looks good so far,just hope that it works the way i think it will. thanks steveL.

Very nice job, im inspired, gona get started on one ASAP. Just a quick question aswell, did u have any problems with deflection? i would assume a drum that long had some deflection in the middle. I was just wondering how much it arcks in the middle, 1/2mm, 5mm, nothing? Just curious

hi,im not sure if you were asking me if mine bowed any,it does just a very little,maybe a 16th of a inch if that much.it runs extremly smooth,no bounching,no vibaration.
