I tend to look at import vises, and Wen is imported, as a kit of parts that I could maybe make into a good tool. That and old vises. I've got a Brown & Sharpe #1 here that I picked up off ebay, as well as the import angle vise I got several decades ago, and the one that came with Smithy 3-in-1 machine my brother bought. I'm probably never going to get a real Kurt vise, being a retired hobbyist. So it's old beat up stuff, or new import, or sometimes old beat up import, for me.
I am nearly done with my class, but need a lot of practice, and still have a lot to learn from that practice. I took a class in machining in high school, in 1973, and didn't do much but dream and read about it after that until 2008, when I was able to buy a very small import lathe for the first time. I'd done some other kinds of metalwork, so kinda know my way around a file, hacksaw, drill, and such. Done a wee bit of blacksmithing, and a tad of armouring, some jewelry work, picking up dribs and drabs of knowledge and techniques as I could.
After not doing to well with that mini-lathe, I griped to my wife, and she suggested that I take another class. Started that in the spring of 2015. Still in it, having been going mostly very part-time. I'm a pretty good mechanic, so most of the machines I've bought are in need of mechanicing. Got two of the 4 lathes running, need to clean the lathe spindle and associated parts, lube and reinstall them, and then the Smithy will be running. It was bought new in 1997, and never actually run, just sat there until recently. I've been working on it for about two or three weeks. Hoped to have it done a week ago, now shooting for a week from now. Gotta finish fixing the parts washer to make it easier.
Then I have a Lewis shaper than needs a new jackshaft, and a good clean and lube, and about then it will be time to work on the South Bend Heavy 10L. It's about 80 years old, and spent five of those in a leaky barn before I laid hands on it. About two thirds of the clean up still to do, before it's ready for paint and reassembly. Then I'm going to have to learn to use all of them properly. I do have enough experience to not expect an import vise to be accurate off the shelf. Played with too many of them over the years. If you're talking the one I think you are, i.e., this one:
https://www.homedepot.com/p/WEN-4-25...34TV/304665580 they're the same as the ones I have, though one of mine is a no-name, and the other branded Smithy. According to the link, there, it's under a 2 year warranty, so you might be able to get it fixed, or replaced with one that is more accurate. Though with the experience you have, you can probably do a better job fixing it yourself.
