For more than two years i keep telling myself I need to build this jig. I finally got to it.
In Israel, where I live, the metric system is the formal measuring system (thank god!), but with some exceptions: all the plumbing hoses and items are sold in inches, and also threaded rods and screws. Metric items are avaliable, but they cost almost double.
I don’t have much to say about the jig. I often find myself confused about what standard a randow screw is. This solves that problem. But I have a lot to say about the imperial system: its ridiculous.
Why should we stay with a system that it’s principles were founded almost 1,000 years ago? It is like using roman numerals instead of decimal numbers. Not only that the inch is 2.5 bigger than a centimiter, therefor less convinient. The system where its divided to fractions in such a weird way, is not making any sense to me. The decimal system is here, why not using it?
Oh well; i guess that its like the differences between cabinet saw and a sliding table saw. For some reason, seems like most American carpenters preffer the cabinet, though there is not even one advantage to that that I can think of.
Some things i will never understand.

Growing up in the States, I’m used to the English system, the system they don’t even use in England anymore, with all the inches and fractions. I have used the metric system, but still revert to the English way out of habit. All I know is 25.4 milimeters is equal to an inch, and then I take it from there.

That is really handy looking. I might have to copy it.

In a world of different standards keeping organized is key. Looks like you nailed it with this one

I don’t think there is a serious defense for the imperial system aside from inertia. Of course inertia is powerful. Do you use a QWERTY keyboard or Dvorak?

With regards to “most American carpenters prefer the cabinet, though there is not even one advantage to that that I can think of.” I will give you the two most obvious ones to me:
1. cost
2. space

With that said I now enjoy my slider very much…

Different strokes for different folks I suppose. The basis of the measurements in metric are something like the speed of light in a vacuum and the exponentials thereof, so I wouldn’t worry about imperial being based off the length of a kings foot at some point and barleycorns and such. Both are equally useless in your everyday life. I learned in inches, feet, and those fractions, so they make sense to me. However, due to minimal effort of the school system in which I partake here in the states, I can convert them if I need to. The conversion in the U.S. should come sometime in the next 100 years, but if I’m making something, I’m making it in inches and that’s final.

Myanmar, Liberia and the good ol USA, the last hold outs of the antiquated Imperial system.

Don’t refer to it as the English system because that is confusing as heck :P You use imperial. Everyone else uses metric. Refer to them as anything else and people will start scratching their heads!

I have also been telling myself that I need to make one of these jigs. Well done sir.
Though, I would like to suggest; you could make the related jig, comprised of bolts or threaded rods, to complete the set.

Well the system has been around for 1000 years or more so it must work for someone , Me I can’t understand the metric system and find it as confusing as you apparently find the imperial system. To each their own .

The imperial system is based on HUMAN factors. Unlike the Metric system is halves, and halves, and halves again, easily.

Yes, the Imperial system is arbitrary. So is the metric system. There are advantages to both, and disadvantages to both.

The U.S Dollar is based on the metric system. Why not the general rule of measure then? Because, it would cost millions and millions of Dollars (again based on the metric system) to change everything else that uses the Imperial system over. It’s just a matter of simple “metric” economics.
