I was asked to cross post my ultimate vise project for you all to see. You can read more about it here:

In my shop, I’ve found that my most used tool is my bench vise. I’d long wanted a larger, more precise vise that I could use for everything from holding machined parts right out of the mill for tertiary operations to pressing components together to holding parts for general fabrication. Because I tend to do so much grinding (largely with a 2x72 belt grinder on the same bench as my vise) I’ve long appreciated the sealed construction commonly seen on Wilton bullet vises. I spent a while looking for one that would suit my desires but between the prices in my area and the features of the vise that I wished were done differently, I decided to turn this into a rather ambitious project: building my ultimate bench vise from scratch.
This started as a rather simple list of requirements:
- 5” jaws with the same screw pattern as my current vise so I could share soft/hard jaws between my vises
- 10”+ maximum capacity for holding large parts
- Sealed slide/screw assembly to keep grit out and grease in
- Thrust bearing in the dynamic jaw for more efficient transfer of applied torque to clamping pressure
- Fine pitch (8 tpi) ACME lead screw for high clamping pressure
- Removable handle with hex on lead screw for operating vise with a drill
- Swivel base with dowel pins locking the vise at 45˚ increments so it can’t swivel unintentionally under high loads
- Hardened and removable (for resurfacing) anvil
I spent about a year tinkering with the design in CAD before deciding to commit to trying to make it. Over that time I came up with a number of fairly unique designs to help achieve my goals with the equipment I had access to.
