Hi All. I need 4 or 5 posts suitable for holding mirror mounts (e.g., MM-1) and the like. Almost any length of post would work though posts in the 2 inch to 5 inch long range would be ideal. I need to upgrade my holography bench a bit. Please let me know if you have anything that you would be willing to part with or if you have any suggestions of where to look. TIA. Ron
