I know that BPI sells a hull vise but I have a lot of scrap 7075 aluminum I've had for quite a while and figured I'd go ahead and use some of it to make my own. Besides, I do so like machining aluminum
After squaring up the base plate, I radiused the top edges.
The holes were all located and drilled for the standing jaw.
Once the standing jaw was attached I then laid out and drilled the holes for the moving jaw and it's guide plates, and the toggle clamp.
Here it is all done. I didn't figure it'd be of much use to show squaring up all the pieces, drilling and countersinking the holes & etc. Works like a champ and was fun to make.
