Built this fly tying vise for a bout $20 in material.
Used Drill Press
Tap and Die
drill press vise
Step 1: Get Material to Make This Vise
You can use any material that is sturdy enough , such as wood, metal, or solid plastic. I used hardend steel for this project. Bar stock was 3/8-1/2" thick with the base at about 3/4" to 1" bar stock from a metal supply company.
Step 2: Drilling and Tapping
I drilled a hole in the hardened steel first 3/8". I then cut the jaw material to length 3"-4" or you can go smaller if you like. Then keep the jaws together in a drill press vise or other portable vise. Before using the angle grinder for the tapering of the jaws, I drilled a 1/8" hole in the middle of the two halves of the vise. I then started with the drilling of the holes for the set screw closest to the jaw and the tightening screw. On the side of the knobs for the jaws for set screws. The knob closest to the jaws on the side of the knob is not tapped, however is drilled, conversely the other side is drilled and tapped. The lower tightening knob on the side of the knobs is drilled and tapped, however the hole does not extend through the other side of the jaw completely, rather just about 1"4" deep for a pivot point. There is a third support hole on the jaws that is tapped (the one that attaches the jaws to the round stock material. All bolts were 1/4", so find the right tap for this size thread, I believe I used the 7/32 drill bit size and this worked fine.
There is round stock going through the hardened steel that is a little less that is 3/8" thick. This is the rotatory component of the vise and where all other pieces that have been drilled to the 3/8" holes are attached and secured with 5/32" screws (these can be cut down and made into set screws), I left them as this is just easier for the time being. you will have to tap them with the correct tap size, there is some variation allowed as I did not have the correct size drill bit. So, I improvised as the overlap of the threads just has to be enough to tighten without slipping 50% or greater is acceptable.
So overall cost: $20-$32
Hardened steel for body, handle, and jaws
Round Stock for rotary component.
1/4" lag bolts cut to smaller length as needed
1/2" or bigger plumbing plug for tightening cap
Small bits of cherry wood for knob material (other hardwood is acceptable)
Mortise cut to fit the hardened steel solid stock in 12" by 8" piece of wood (customizable if needed)
Epoxy for securing cut lag bolt threads to wood.
