hi skin and everyone else,
at the national machinery we built cold headers but they also used to build warm and hot forming machines also.cold heading machines typically take a spool of wire up to 1 1/4 inch in diameter and spits out bolts to be fed into a threader (which we also built) for the threads to be rolled on the bolt. we also built ball and roller headers to make bearings. the smaller ball headers made about 900 balls per minute.those things would fly! they also made more complex parts that were used in alternators.i'm sure you would like it and find it interesting.
belt buckles eh!? i don't think a heading machine will be cost effective but... another of my "get rich quick schemes" was emblems for the side of /5 bmw that go on the engine. i had bavarian motor werks only in german, like on the steering head, machined out of aluminum and sold to replace the original. i wanted to sell about 30 (15 pairs) and give the rest out to friends who have a bmw for christmas. well i sold 1 set and did give the rest away.this was not one of my better ideas as it cost me about 500 bucks.
to make a short story long i found a guy who does this sort of thing and i see on his business card that he does buckles also. he does cad/cam and cnc design and machining. joe kenny
jkenny@swva.net maybe he can be of help for you.
there's also tom rolland on the bevelheads list who is a clever little fart,says so on his web thing. he makes ducati buckles out of silver and brass(i think). do a google search for him and i think you will find him. if not let me know and i'll dig alittle deeper. you may get some ideas for your buckles from his site. i think the silver one's are about 100 bucks (usd) and the brass somewhat more affordable. he has them cast and finishes them by hand. sounds like what you want moreso than something machined although kenny did do a nice job for me on the emblems.
the job interview went good but i won't know if they want me till they call or worse yet i get a letter. sounds like i could work 8 days a week 12 hrs a day if it goes thru.that would be steel mill hrs again but the saying is "if ya want ta play ya gotta pay" or something like that.
what a great bunch of guys ya'll are and i sincerely mean it. i wish everyone could come to mid-ohio for vintage days as i'd buy everyone a beer.remember,i live about 45 miles from the track.
best regards to all, wiggs
