Jrobb, my 2C arrived with the swivel bolt missing! EOC Jason sent me a cad drawing of his to copy and ritzblitz made me a new one. However, there was no issue with the static threads. You'd be best to ask someone on this board to mail you a tap to borrow, or at the very least grind off a slice in the bolt you plan on using as another member suggested. The 2C's lines are imho the very sexiest made. It is what I envision when I picture a combination vise, absolutely quintessential! Please proceed with care
