I’m planning a drum sander to build and need some help.

For the lift I am planning on using 4 threaded rods 4 bushing. 4 sprockets.

Will a 1/2” threaded rod be enough?

Any suggestions would be greatly appreciated

Thanks
Mike

All the shop-built drum sanders I have seen have manual adjustment via the feed bed secured with hand operated lock nuts that ride in slots cut into the sides. Most have a single threaded rod in the center of the infeed side. The drum does not move (since it is linked to the motor by the belt).

I used a $15 scissor jack from harbor freight which works great!

If you want to use threaded rod for lifting I would use something with 16 threads per inch. That way you know that one revolution is raising the table by 1/16 inch, or if you only lift one end with the rod, then 1/32 inch per revolution.

Not sure what you’re planning but the Shopsmith design uses a threaded rod/wedge combination that reportedly works extremely well.
