FINALLY! Drum Sander Pics

This has been a major work in progress.  It is still not done, but it is a working prototype.  It does what I need for now.  I used cut disks of MDF and glued them together to make the drum.  I then turned it as true as I could. 

To lift the bed (creating the thickness) I have a large threaded rod and a bolt.  I don't like having only one point to raise and lower the bed, as it is not very stable, but I will find a way to fix that in the future.

If you have any thoughts/suggestions, please feel free to share them with me.

Very cool!

I've seen lots of folks who build this as a standalone device, using a motor and pillow blocks, but it's genius to use the lathe!

One hint I've read: after you turn the cylinder as even as you can, run very coarse grit sandpaper through AS THE WORKPIECE against the bare MDF cylinder, and that way you transfer the flattness of the bare workpiece backer board (MDF) to your cylinder.

Good luck w this - might build my own!
