I understand, but I don't think Wilton vises were priced well either. I saw a video of their factory once, and it was terrible. Very out of date, lots of and lots of manual work. You would see vises moving around in fixtures while the jaws were being machined (e.g., they're now scrap). It's no wonder why they charged what they did for their vises.
I thought ~$2000 would be a fair price for a U.S. made, cast iron vise the size of the Fireball Tool, made with modern manufacturing techniques. Look at something like the Orange Vise company. They're manufacturing machining of similar size and weight to the Fireball vise, out of solid blocks of cast iron, but for thousands less. Yes, a bench vise is not a machining vise so apples vs, oranges, but still. The Orange Vises are machining center vises, so they need to be extremely accurate and precise with precision ground surfaces and ways. The Fireball Vise (while undoubtedly a quality piece), is a crude sledgehammer in comparison. Making a vise out of a solid block of iron that you machine most of it away should be the expensive way to make a vise. Investment cast parts should be far more cost effective.
My theory is that their foundry partner just wasn't prepared or setup to really handle the type of castings needed, and they weren't able to get a good screw machine shop to make the leadscrew and handle components. They're probably way under water on the U.S. patterns and foundry time, and probably paying some small shop $175/hr to make the screws and handles at very low production runs.
Like I said, I'm sure it's an absolute beauty of a vise, just disappointed the price came in at what it did. They're probably going to be hurting on those pre-order vises if they stick with their "Made in the USA" promise.
