Introduction: My Metal Vise
In this instructable i make vise for myself. Its very simple design, and easy to make.
I made it for holding different shaped workpieces.
As a material for the frame i used 10mm thick mild steel, those pieces we're leftovers from flame cut openings, and got them free.
As a "slide" i used 50mm x 50mm x 5mm square tubing.
12mm steel rod for handle, two M12 nut.
16mm trapezoidal threaded rod and nut.
Six M6 screws to connect jaws.
Spring, and three washers ( 18mm inner hole, 30mm outer diameter)
You need atleast: welder, drill, and somekind of metal cutting tool.
Video shows the whole process.
Step 1: Slide..
I call this part "slide", i don't know if it has some official name too.. for me its slide.
I made the slide from 50 x 50 x 5 mm square tubing.
I cut 35mm wide opening to it. This way it still has four corners.
Corners makes it more stiffer than reqular u-channel.
I made the cut to opposite side of the welding on the tube.
Square tubes manufacturing process lefts some tensions to the tube.
When you split it, it usually opens little bit.
After little experiments, i noticed that when cutting from that side wich is opposite side to the welding of the tube, it stays somewhat straight, only ends opens little wider.
After i had cut the opening i cut out wider sections from the both ends.
For cutting i used cold cut saws.
Step 2: Parts for the Frame..
Frame is made from 10mm mild steel plate.
I made the cuts with chop saw, and angle grinder.
I drilled 8mm holes to every corner of the bottom plate, for attaching vise to the stand or table.
6mm holes to the jaws, and through them i made 5mm holes to the faceplates and theaded them with M6 thread.
This allows me to remove jaws when necessary.
Step 3: Front Faceplate..
To make front faceplate stronger, a weld two 10mm plates together.
Weld with Esab ok 73.15 rod with 109A
Then i drilled 18mm hole through the faceplate for M16 threaded rod. Little clearance lets frontplate to move easier, and it doesn't get so easily stucked from dust. ( from grinding etc..)
Last picture in this step shows the idea.
Piece of plate under the nut, rises its center point to the middle of slide, but it also guides the slide sideways.
Step 4: Assembling..
I started by welding the nut and the riser on their place.
I left the sides of the riser unweld, that allows slide to move unobstructedly.
Then i tack weld the sideplates, i left 1mm clearance for the both sides of the slide.
And 0.5mm clearance between the "lid" and slide.
I weld the parts together with Esab ok 73.15 rod using 109A current.
Step 5: Continued...
After the parts we're weld together i rounded the corners and removed splatters with angle grinder using 80 grit flap disc.
To connect the handle to the threaded rod, i made thick "washer" from 30mm bar stock, cut 25mm long piece from it.
Drilled 16mm hole throught it, placed threaded rod though the hole.
And drilled 12mm hole through both of them. Then is shortened the rod, and finally weld them together from the both sides.
Step 6: Finished..
To get the vise also open, i placed 5mm thick washer inside the slide, then 50mm long strong spring, and washer again.
I weld that last washer to the threaded rod with small, but strong welds.
This process is little difficult to explain, specially with my english skills...sorry
So, i succest that you watch the video if interested to know more. I tried to show the whole idea on it.
Thanks for watching!
