Currently working on a Sphere jig then want to move on to vacuum chucking. I work in industrial Maintenance and have access to some machines to help me. I made a crude steady rest a few years ago out of scrap it works well. Have also made my own deep hollowing tool and some turning tools with easy rougher bits. I hope to be done with my sphere jig today or by next week. I will post some pics at a later date. Thanks
