That saw was built by someone who likes tools more than they like to cut rocks.

Looks like the Swiss watch of rock saws.

I had a homemade saw that used a stepper motor for the feed with a speed control and automatically returned the carriage to the front of the saw after making a cut. Motor lasted a dozen or so cuts.
If someone tells me something is the "Cadillac of saws, I tell them I'd rather have the land cruiser.

When I first glanced at this I said this guy has some machining experience basically because the clamp system he is using is common to milling and drilling, as I read on I see he must be if fabing race car parts etc.. The vise system is the only unique part of that saw from what I can see, and appears to be a piece of aluminum with some holes drilled in it that could be adapted to just about any standard x-y vise that comes on a standard rock saw and the cross slide accuracy of .002 inches that is way out of reality for an eighteen inch slab saw even new and on a never used saw the flex of the blade alone would be more than that, a piece of paper is roughly .003 inches. Not to belittle the guys vise deign I think he is suffering from delusions of grandeur as to the overall saw, that being said I think I may adapt his vise idea with some modifications. Jut my .02 cents

He's using linear bearings, I wonder how long they will last before they destruct from rock sludge, I can't see too much thats earth shattering about his build.
I am toying with the idea of building a big saw and contemplated linear bearings for a very short time, If I ever do build it I think I will stick with the old rollers on rails design, if I went for slide bearings probably one of the graphite/nylon (Delron)simple bush type bearings, that stuff lasts forever, even in shitty gritty places.

Big Barranca saws use linear bearings. Don't know anyone who has one so I don't know how they work out.
My FranTom has Bronze bushings on round rails, makes excellent cuts and easy replacement if I ever need to. Delrin is intriguing.
The roller bearing on square rails works fine too if you keep the oil clean and don't mind a little slop in the carriage so it will ride over debris on the rails. Lots more trouble to fix too.

Of course the one saw I keep seeing anywhere near me is this one. This thing has been spammed on CL for quite some time.
