Thread: A huge drum sander

G'day all !
Now the table is reinforced & blocked with a pair of F clamps (to ensure the parallelism with drum)


And under the table you can see reinforcements:







Absolutely, next step is drum final calibration

Finally, on of the two dust hood lateral covers (the left) is now ready



Drum without dust hood, befor covering with lacquer



And after





Dust hood and height adjusting mechanism lacquered

Hello all,
Being employed in a jd dealership as parts manager you always see parts that you think.... well I could use that to make my next machine....
The thought I had for a drum for the sander is a ruberrized or non ruberized baler roller! VERY strong and also machined true!
you could easily drive it from a pulley as there is already a place for a sprocket on the end!
the only thing is would be that you would have one giant roller about 6 feet long, but on the flipside it wouldnt take long to sand a dining room table top!!!!
Or you could also use a windrower (swather) canvas roller that is a lot smaller in length but still steel so very little flex.
Anyone wanting pics of these above mentioned items to get a better idea of what they look like or what they are let me know!
thanks all
Nathan

Hello!
Pictures with drum sander at finish:

1. View from the front left



2. View from the left-front



3. Adjusting thickness device - detail of fitting, view from right-back, side with hinges. The range of thickness is from 0 to 110 mm (enough for me!)

4. Detail of stretching belt device (allow a wide range of V-belt length)



5. Adjusting height (thickness) device



6. Adjusting height (thickness) device - closer view of handling wheel (divided in 10 circular sectors, 1 sector=36 degrees=0.1 mm height adjustment)

7. Sanding paper convoluted on drum (view from right-above)



8. Sanding paper attached to drum with two hose clamp 150-170 mm (detail)



9. Assembly befor attaching the dust hood cover and V-belt guard

10. V-belt guard placed on table (view from outside)



11. V-belt guard placed on table (view from inside)



12. Final fitting of the assembly

13. The maximum lenght of the pannel which can be processed is ...



14 ...You can see now in this closer view: 1060 mm (enough for me!)



Do you like my drum sander?
What do you think about the color combinations sky-blue + blue ?
Critics welcomed

Kind regards!

Looks good Lucian, good for doing whole table tops!

I recon you are going to need some bigger dust extraction ports..... I'd be thinking, 2 x 100mm.

cheers

That is awesome, you are very skilled to do that and I like the finish. One thing puzzles me though, How do you hold the paper on the drum? Is it just wrapped and held at either end by the hose clamps? No glue, velcro etc?

very interested

"Is it just wrapped and held at either end by the hose clamps?"
Yep certainly is... probably do a better job than the ones that are shop brought.
