VexPro still out of stock?

Our experience was less than excellent using the 6061 1/2" hex from McMaster this year. It was as much as 0.005" over in some places, making it nearly impossible to install into the hex bearings and some of the hex collars. We did find the 2024 aluminum hex to be slightly undersized and work perfectly for us. It's significantly more expensive, but we didn't mind the extra strength it provided.
