Now are these scales able to be cut down and made smaller?

No cutting these scales. You need to let the seller know the lengths you want.
Line from the add:
You may choose any 3 pcs scales measuring length under 1000mm at this price. In fact,The scale can be made from 0-3000mm.Scale length above refers to the real travel of the linear scale. Actual physical length is 142mm longer than travel. One inch equuals to 25.4mm.

With their misspelling and all. You will want to tell them the lengths you want in millimeters. 0-3000mm....ok who orders a 0 scale? usually 50mm is minimum.
Line from the one I purchased:
1. This order includes one piece 3 axis digital readout and 3 pieces linear glass scales and other mounting bracket(whole set), there are 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm, 850mm, 900mm, 950mm and 1000mm available for this order, you may choose any 3 pcs linear scales within these.
2. After making order, pls kindly tell us the travel length or total length of scale you need.

Make sure to measure the axes travel of the actual machine that will get the scales. Do NOT use numbers out of a spec sheet or anything else. Axis travel is easy to measure accurately. Then add more to the scale travel length beyond that, never the same or less. Otherwise, you will end up with a crash. There must be more scale travel length than axis travel. Beyond that, if you make the scales 1 mm longer than the travel, you will play hell trying to get the scale mounted without interference (CRASH) at one end or the other. Making sure you have enough space, go oversize by at least an inch or more to make the scales easier to mount to the machine without fussy measurements. Extra length, up to where it becomes floppy or interferes with something, is not a problem, too short IS a problem. Bottom line: If there is not enough room and the read head can reach an end bracket of the scale, it will at some point, no matter how careful you are, and it will crash. Make it idiot proof from the beginning and all will be well. Make sure of what dimension the seller is asking for and supply it in precisely the way he asked for it. Make sense?
 
Yea unfortunately i dont have the mill yet but the lengths i used should be fine.
 
We'll have to compare when Brento's arrives from Aston. I think we've got 3 or 4 from Siton.
Greg, Russ, Bob, Eddy and others that I'm forgetting have ordered recently.
Might be helpful and informative if we did up a comparison of the 5μm sets & 1μm sets and the vendors that they came from.
