Hello, everyone
Recently I fall in the necessity of change some broke spokes of my 26" wheel bike, and notice that I didn't not have any spare at all

, and for make the things difficult remembering that some time ago I changed some but fail cause I never match the original thickness of the spokes, I must confess that my knowledge about spokes has been just basic measure and change, period, but as usual the necessity always seems to appear and more than ever,

so checking and gathering some information and become more in deep, now know that there is a thickness, length, material and precision with tension, I get notice that there is a chance to reuse some spokes from a 27" wheel that is just falling around and with no really future use, only thing just cutting and threaded and in my "theory" seems just easy as that, so checking on the world wide web, I found this

in action through you tube videos seems quite easy, but it is??, nice machine somehow expensive but could be nice to have, but asking something that I couldn't find in any video, what kind of advises can you give me, I really want to know cause I am a user and changed in regular basis spokes from my two bikes 27" and 26", I broke some spokes cause I use airless inner tubes and unfortunately the roads at my community are in very sad condition most the time are compare like stairs one crack every six feet

and since I use my bikes not only as recreational but as a tool, so most the time I carry something over 20 to 30 pounds at least besides my 195 pounds

, so go figure all that pressure along with the bad condition of the road, cracks everywhere and not pneumatic inner tubes is reasonable that from time to time the spokes tend to bend and brake

but again what else I need to know, oh, by the way I just recently bought a ruler that I think can help my to identified some spoke thickness

and well I am still waiting for it, there is another with better information and may be quality from VARTOOL but unfortunately couldn't find here In America continent seems to only be sale in Europe, so the price is somehow out of my budget

very nice tool, but again couldn't find it, anyway before to do anything else I was really thinking to start to do it my own threading since I have a some spokes which never match the necessary size, but again I would appreciate any advise and commentary that helps in this interesting trade.
Please and thank you
