Sanding solution

[justdraftn]

I needed drum sanding bigger than 4 1/2 on my spindle sander.
So, I bought 2 sets of spindle drums.  Cut one set in half.
The same w/sanding sleeves.

 I tried using all thread for the posts.  One worked "ok" but had
some wobble to it.  The other pieces were unusable.
 So, I got 1/2" carriage bolts. Ground off the square corners
off so the washer would seat flat. 
 


They work great.
