Indeed. I knew it was not a cheap item, and looking online today, it's a mere $2300! > A very cool machine, reminds me of the manual punch we had to go along with > our trip punch at a previous job. I've wanted to look into buying additional dies for mine. All I have is the 1/8" tubular rivet setter. The bottom die has a 1/8" projection that the rivet slides down prior to setting. Some years before I started, someone broke that off (it would be easy to do if you were about to press the pedal and let the PCB slip from your hands - the weight and torque would easily stress the projection). I heard replacement dies were around $250. I haven't had a project that was important enough to research other types of dies. >> Stu Phillips, a friend of ours did the insertion of metal metal Southco >> extractor handles on our boards for the Microdata 1600. > > The blue handles on the MDB Unibus prototyping boards I've got are Stu > Phillips handles. Ah. I probably have some I can check for makers marks. > They are indeed riveted on, but I don't know if MDB did their own riveting. > With the amount of DEC-compatible stuff they made, it wouldn't surprise me. We did our own riveting at a smallish company, so I expect they did too. -ethan
