Nice little project,,,I have done similar to that,,,,using 3 short lengths of angle iron,,,2 facing down to form an "M" ,,the third one facing up and cradled by the other 2,,,the V piece has two holes drilled in it for a plug weld to hold it all together,,,simple and quick,,,,problem is ,,,when using it,, it slides on the drill press table and makes it hard to keep position,,,,,my answer to that was to buy one of those X,Y vises mounted on the drill press table,,,,and use a store bought V block or adding a strap across the homemade block and adding a tongue to it to clamp in the X,Y vise...Home made Jig's and other tools always give a guy a sense of pride..
Some of those lies people tell about me, are true
