I need some "donor screws" to be cut down into super-stubbies. So if you have any un-useable 10 cm screws you'd part with for, say $15-20, let me know. I'll pay more for silver hanger Express 10s. I can also use BD 13s, preferably the old ones: un-colored knob Turbo Express or the next generation with the gold knob and the triangular hole in the hanger (the threads go about 1 turn higher up the tube on those versions). If you want a super stubby of your own, I'll trade 2 donors for 1 finished 7-8 cm screw made therefrom.
I have a good condition 10 cm turbo express with a silver hanger and red turn know, as well as several 13's with silver hanger and gold turn knob. I'm in the process of shifting my rack over to aluminum screws, so if you have a use for these, let me know, I'm sure we can work something out. email me at brunoschull @ hotmail . com
