Having just made a batch of half nuts for Homes and Triumphs I respectfully submit that Home and Triumph leadscrews do not have a buttress thread, but are 60 degree V threads.
Took a bit of research as there are contemporary reports that a buttress thread was used, but close inspection under a microscope clearly show the V form. If anyone is in need of a quality 3/16" or 1/4" half nut in steel with correct size machine screws, they are available at $20 and $24 respectively, including postage. Hope I haven't stirred up the proverbial hornet's nest. Mike Tucker (mtuc...@exemail.com.au) _______________________________________________ Phono-L mailing list http://phono-l.oldcrank.org
