1" precision screwless vise
Those that know me and actually pay attention to my submissions have probably noticed I have recently added a new milling machine to my workshop (dining room)! This is one of the projects I have made with it, a 1 inch screwless vise (also called a precision toolmaker's vise, or precision machinist vise. It depends who you ask), so named because it does not have a large, traditional acme-thread screw running the horizontal length of the vise (like this http://3.bp.blogspot.com/-VWfcT556V.....Bench-Vise.jpg )
But, I digress! Yes, I made this myself! 1" high, 1" wide, 2 7/8" long. Material is 6061-T6 aluminum, the screw is an M4x0.7, hardened steel. Holes are 5/16" nominal, spaced 0.400" apart on center, with the center of the first hole directly underneath the clamping surface of the fixed jaw. Everything else I pretty much winged as I went along. Tolerances aren't super-high, as I didn't really intend for this to be put into serious use (it is aluminum after all), but it works very well, and could be used in a pinch.
The upper pin on the movable jaw has a clearance hole drilled in it for the screw, while the lower pin is drilled and tapped for the screw. When you tighten the screw down on the workpiece, the screw applies both forward and downward clamping pressure, preventing the movable jaw from lifting, ensuring the work is held perfectly square/parallel in the vise.
All in all, made this in a single day with frequent breaks and a trip to ENTS to turn the pins on the lathe. I really need a lathe. :I As for the exact number of hours spent? Pfft, I dunno. I wasn't timing it. *shrug!* Anyways, I had fun, and just thought I'd share a little project I made, 'cause someone is bound to eventually ask me, "durr, why do you need a milling machine?"

Who DOESN'T need a milling machine? I recently picked one up for myself, though a very different style to yours: https://dl.dropboxusercontent.com/u.....705_204010.jpg
The only other "machine" tool I have is a drill press, and it's not good enough to worry about the precision of my vise. Too much bearing runout. Was a cheap Ryobi deal.
A lathe is next on my list of tools to buy, though to get one big enough for what I need to do, it'll be a while.

Yeah, I used to have a cheapie drill press too... You can see it here: http://www.furaffinity.net/view/7019656/ Just a Canadian Tire special, was $90 brand new, so well worth it. It served me for a couple years, and then I sold it, along with a large assortment of drill bits and the cross-slide vise for $200, once I got the milling machine. :D
Nice. Looks pretty much the same as the one I got. I wonder if a cross-slide vise would be worth getting for mine. Seems a bit redundant with a mill on the next workbench over, but could be handy.
that is a delightfully well made piece of precision machinery; my hats off to ya, orci:)
Excellent surface finish! Dining room quality. Glad to see that you put the milling machine to good use, that's really cool!
This type of vise also applies downward pressure to the movable jaw, to prevent it from lifting as a part is clamped, especially if the part is only being held on the upper portion of the jaws.
