Do You Do Anything With Your Old Office Chair Bases

As the title indicates, just seeing what others do, or would do, with their office chair bases.

Since they are pretty stable, roll well and will hold a lot of weight, it seems a shame to just trash them. And I find the casters of little value for other than chair bases.

Currently, three of my old chair bases have jobs:

(1) First built was, my lathe knife rack.

I added a top, which provides another horizontal storage space for lathe related this-es and that-ses.

(2) Second built was my welding equipment station;

(3) Third is my knife sharpening station. It holds three different sharpeners. One in a box.
