With this I`ll be going through the process of making Craters MK 2,these pics show the second marking out stage of the process,the first 8 corners have been cut off creating 14 surfaces/flats,the crosshatched areas in the pics will be cut off,creating another 12 surfaces/flats so in total will be 28 surfaces/flats to chuck/hollow from and I`ll add more pics as I progress with the project,Oh I`m going to try screw chucking with a cone type support this time,small dovetails on the ends of the craters wern`t to successful last time (came off the chuck 2-3 times),cheers,Eric.
