I posted these pics a couple of months ago. I finally got them painted, and I'm very happy with the finished result The slider tubes are 3/16" wall 2x4 tube. The steps I CNC routed out of 1/4" aluminum plate. I painted it all with Eastwood's Chasis Black paint in the aerosol can. Then I sanded the tops of the bowties. I hand painted the insides of the cutout K5. I've only done that on one side, not sure if I like that part yet.
