Nice videos. Some interesting notes
The first vise, the HF central forge 5" vise. Casting held everything he could throw at it. Held its own IMO with clamping force. And only with a 4' cheater pipe was he able to snap the thread-rod.
Same thing with the wilton tradesman. Broke the thread-rod (spindle) but notice the hollow jaws never posed a problem
Alot of the other vises failed or bent major stuff other than spindles. But didnt see jaw casting failures on them?
I agree that swivel bases are a weak link. Its a sacrifice that makes the vise much more user friendly. But I think that the wilton "bullet" series has one of the best swivel mechanisms and with the teeth, it DONT SLIP like the ones that just use the bar and friction.
I have a HF 6" vise from back when they were "pittsburg" brand and not central forge. I have abused it and never broke it. If I need more clamping force or tryign to "unthread" something and the HF keeps slipping around the swivel....I have a wilton
https://www.wiltontools.com/us/en/p...jaw-round-channel-vise-with-swivel-base/28826 IT has been used and abuse and keeps on ticking.
The issue with some of the older vises (I have a columbian. I think its a 305)....is while it is solid and casting is strong.....they used some basterd stuff that you cannot get parts for anymore. It has a stripped out spindle nut. But its a funky looking piece with a dovetail base. The spindle threads are NOT anything that is common and CANNOT buy a tap for. Looks similar to this
Wilton 11114-15 #4 Spindle Nut W/Pad-Repair Part. But is discontinued. Can no longer buy spindle or nut. I have thought about cutting it off, welding on a rod-coupling nut, and making a spindle out of all-thread.
But certainly a nice video. Wish some bigger vises were tested.
