Smitty and Gman great looking Prentiss's guys!
That's a neat little locking system on the Dropfo, Dave.---It's right interesting just how many different vises have an auto-locking system like that.---While everyone differs slightly from each other, they all (the makers), built on the same idea.---I don't know just how many there are but I know of a few.
(1) Your Dropfo.
(2) The Gyro.
(3) Versa Vise
(4) Rock Island Auto Lock
(5) Pittsburgh Railroad
Help me out here fellows.---I know there's more.

Numbers 2 - 5 are JR Long patents!
Fulton's NuTyp (based ob Hiram Reed's patent)
Ek vise (Based on EM Ek's patent)
Volt's patent - never seen one
Wood's Universal Vise??
Multiple Ball & Socket based Vises
More to come as I dig deeper into my patent collection.

Thanks BobSmitty and Gman great looking Prentiss's guys!
Used an entire can of brakleen on this thing, it was jammed FULL of hard old grease. Followed by a dunk in hot soapy water and we have this. I lubed it with Superlube. Now the swivel base works and the wedge lock works too. I am using a Plomb 1/4 drive sliding T as a temporary stand-in for the swivel lock handle. I need to make new jaws. At least it works now!
Edit: I need to remember to lock the swivel base before I carry the Dropfo anywhere. As it will just fall off, no method of retention other than gravity and the lock.

Looks like an unmarked Sears Craftsman.---No one knows who made those either.---I think Zoomie has 4 of them.

You sure don’t! Great find! Is it in your possession already?![]()

Today’s booty, you know you have a problem when you drive an SUV but you load the vises on the front seat.
Stuck in traffic btw

Smitty
Nice haul as usual
While we all here to varying degrees have this affliction, man yours is of the chart! I need to organize an intervention for you (you know it is serious when one addict is trying to help another)
Ps
I guess one problem is that there seems to be plenty of supply and hence temptation for you around there. I think we need to send you to a remote cabin somewhere in Sierras![]()
Well Va between you and Zoomie, you guys have pretty much every vise known to man ( I am actually shocked that you do not have a couple)





Alright, I finally got off the road. Here’s a few better pics of the Craftsman vise no 5241, it has 3 1/2” jaws and weighs in at 32 lbs. When I first saw the ad it looked like they welded the vise to a square plate at the base. I decided to go check it out anyway, I happily paid him the $79 he was asking.

Here are more pics of my Columbian 108
Looks great, what a beast.Here are more pics of my Columbian 108
I must admit I never knew they existed before today but as soo as I popped up I knew I had to have it. LA is a curious place, there are 23,000,000 people in a 100 mile radius from me. Something always pops up.Smitty
Despite the fact I do not want to further encourage your addiction (as if you need encouragement lol) I must admit that is one darn neat looking vise and IMHO and you did very well
Now for goodness sake stay away from CL and Marketplace for a while![]()
That was my first thought but the letters seem to be perfectly spaced. Usually people don’t stamp their property with such precision. It could be a vendor mark.Smitty, do you think the S. M. S. is a PO.?
