Have a small servo products mill. Roughly 6" x 3" travel. Have fastened some jobs directly to table but thinking of a small 2 piece vise, probably 3" wide. Table is 12" x 5". For some wood routing I made a rough 2 piece vise where the moveable jaw had holes for hold down bolts to the table t slots. Then behind that a piece with a horizontal threaded hole for the clamping force. No guide rods between the two pieces. Worked fine. I haven't seen any 2 piece vises with hold downs for the moveable jaw but have read that jaw lift can be an issue so thinking I may put that in when I build one. Wondering if I am overthinking this or the best route to go. I may just buy one if I could find a reasonable quality, reasonable priced one this size.
