Show us how it's done and post some pics.
Look at you being a smug bastard, thinking there's no way a guy like me with too many vises is going to waste an afternoon building a fireball style vise from scratch out of spite...
And to make it a bit more of a challenge it's the Sunday afternoon "no parts run" edition, where I scavenged up everything I needed within rock throwing distance of my shop.
What I scavenged up off the bat thinking I would need. Telescoping square tubing, an acme thread, thrust washer, and nut off an old farmhand 5 wheel rake that I converted over to hydraulics, and a bunch of scrap plate I cut off an old loader bucket that I converted into to a skid steer bucket. Oh and some old jaws from my 6" Wiltons that were rounded over real bad and got replaced. I ended up not using any of that thinner plate on this project.
acme thread and nut with tube cleaned up and end caps made for the square tube.
Those two thick plates that were who knows what from a previous owner of the loader bucket. Tack welded them together and started cutting away everything that wasn't vise jaws in the bandsaw.
Unfortunately my online plans and CAD files didn't say what to do with this giant raggedy ass hole in these plates... So I holesawed them out to 2" to clean them up.
A few other steps happened, and now I'm cutting off the tail to length on the bandsaw. Cut through both tubes at the same time then took the inner front jaw tube out and shortened it up by 3/8" or so...
Yo Dawg I hear you like vises...
Yes I still need to make a handle for it and weld it up. Will probably plate across the jaws on the front and back and extend that plate up to the vise jaw backing plate to beef it up more. I started around 3 this afternoon and after cleaning everything up and putting everything away I got home around 10 to eat some supper. It started raining cats and dogs on my way home so I'm not heading back up there tonight to finish it.
Ready for the scrap bin...
