1 pointI was able to get more parts to make crowd control barriers so I made dozen of them in one sitting. I painted these light gray & then added "rubber" tips to the legs by dipping the ends in a drop of black acrylic paint. I'll make a few more of these up & list them on eBay if anyone wants them.
1 pointA better solution maybe would be that I have on occasion just shaved one side off other bushes to turn them into a single flange. - Easily done with a dremel. But you will likely be doing it to "actual" 3/32nd bushes - ie 2.38mm, not the NSR 2.37mm bushes, so you have to decide carefully what running gear to plan to use with any such bushes.
