Is there anybody using torque wrenches or belt tension gauges?

Just ordered my 8" i3v kit the other day, been reading about printers for 6 years now and decided I couldn't wait any longer.

I always notice that (new) people usually have trouble setting the proper belt tension, it seems to be a common question/problem along with cracking the frames of the cheaper acrylic printers.

The thing is, I've never seen anybody use a small torque wrench or belt tension gauge to try and fine the optimal tension. Same with the general assembly (Especially on cheaper acrylic-frame printers that seem to always crack). I really think some kits would benefit from having torque specifications in the manual.

Is there a reason for this, or is just not considered a big enough problem to go to these lengths to solve?

I made one and used it to set the tensions on my Stratasys but it isn't really possible to use it on my Wanhao, you just have to pull it as hard as you can then nip it up.

Ok, I don't speak British....so..."Nip it up"?
