Members dikman Posted Saturday at 11:05 PM Members Report Posted Saturday at 11:05 PM I made this primarily to use with my lathe but it may be useful for working on sewing machines etc. Copper face one end, nylon the other, copper was melted from motor windings. I found that copper is a pain to turn in the lathe as it galls and creates a rough finish! Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500.

It would also be good for hammering down the thread in seams. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
CFM chuck123wapati Posted Sunday at 10:08 PM CFM Report Posted Sunday at 10:08 PM heck yeah thats cool. did you try using just a file at slow speed? I do brass but havent tried copper.

Members dikman Posted yesterday at 01:45 AM Author Members Report Posted yesterday at 01:45 AM It's funny stuff, my first cuts were using a carbide bit and it actually caused the bit to chip! I reverted to a sharp high-speed steel bit and that went fine until it galled, left a surface with little raised bits on it. I then took very light cuts to smooth it out , used a fine file and sandpaper and finished off on a buffer. Brass is much better to work with on the lathe, I don't think I'll be doing much more with copper. It was an interesting experiment, however, and at least copper doesn't give off those nasty zinc fumes when it's melting. Having said that, kgg got me thinking - a hammer-head profile like a cobbler's hammer might be nice, copper has the weight for it.

CFM chuck123wapati Posted 14 hours ago CFM Report Posted 14 hours ago Interesting indeed. Maybe throw some tin in with it; bronze might turn better on the lathe.

Members dikman Posted 6 hours ago Author Members Report Posted 6 hours ago I haven't got any tin although I saw a chap mix 10% aluminium with it, made it tough enough to hold a bit of an edge!
