content: OK, I am selling these guys for 80$ each.Turned out the deal with blueskull was just a lubrication issue, they needed a drop of lubricant and a cleaning. I freaked out for nothing. I happened to send him a pair that had slightly torn insulation on the handle, he was resent two mint ones. I had to wait a while to determine what was wrong with his atomic clock (it looks like the DAC is damaged, but I don't care for the analog output).They are ESD safe and will cutPiano wire, tungsten, gold, platinum, vectran, stainless steels including MP35N-V and Nitinol.They cost 160$ on digikey.http://www.swanstromtools.com/Swanstrom_MSeries_2_page.pdfhttps://www.digikey.com/product-detail/en/swanstrom-tools-usa/M403EC/232-1039-ND/6677276http://4.bp.blogspot.com/-hBjdX5PkEzg/URKh7QtV8HI/AAAAAAAAA5M/RMM2ExdzBj4/s1600/S007-000386_M403EC-cutters.jpgWilling to trade for microwave stuff like horn antennas, waveguide accessories, attenuators.Interested in high frequency stuff like K band.I got a whole bunch of these for sale. I picked up a bunch on ebay before. Made in the USA.http://www.swanstromtools.com/Reference materials;http://www.swanstromtools.com/life.htmhttp://www.swanstromtools.com/adjust.htm

content: If you can provide a blueprint I could make you an antenna for a pair of cutters. I was a toolmaker/machinist until I blew out my back - now I can only do a few hours of work at a time but I still make things in the shop - just takes me a while longer these days.

content: I think we would need to have a RF guy help us out with dimensions. I saw someone on eevblog did one thats equal height and width (supposedly 50) but I don't know if it scales down. I built two large ones myself out of copper sheet. I think those ones on ebay (formed or cut) probably have alot better performance then my 'oval' ones. I'm basically looking at scanning all frequencies, captain. If you feel the stock and labor are worth it, then I'm all for it, so long we can get a good design. I will spend some time looking I guess. I don't care how its made (i see AVE did copper sheet forming on youtube), so long its nice. I had a bit of a hissy fit dealing with making copper cones without jigs and stuff (they look like a drunk made them in the bronze age). Also, I have the coaxial cable, so basically the two cones with a precisely drilled hole would be all I need, and I don't know what they coat them with.Oh yea, I am also looking for high frequency RF cable. Like RF141 or such. I just got a bunch of hard line (full rigid), but a fair value of something good to 30GHz would be interesting. The flexible kind. Also high frequency precision connectors for RG141 and RG402.And I would also be interested in low loss stuff that is good for ~5GHz in long lengths for remote antenna positioning. Also microwave attenuators, power splitters, isolators, etc.

content: Also interested in semi rigid cable (seamless copper) < 0.141 inches in diameter (i,e. 0.03, 0.02, 0.085)

content: Hmm. I am not really interested in the brick module. I see the clock goes for ~90-120$ on ebay. I did want a working atomic clock. Do you have something else to go with it, like a distribution box or gps dicipline or something? Can alsothe deal with some cash or more pliers from my side to balance things out.

content: Or is the VICOR to power the clock? Is it a 12V to 24V boost converter or are you saying its a line voltage to 24 and 12V to power the oscillator.Also, what is the age of the clock? And is the break out cable included (i don't have molex crimpers and stuff needed to make it, this would be a substantial investment on my part)

content: Can't say I have a use for them. I would probably buy a distribution amplifier to send then 10MHz signal out to my various equipments.

content: Actually, if they are put on a PCB with a divide by two circuit, maybe it could be used to discipline portable equipment (i.e. portable spectrum analyzer) with a small power source.I will take your deal, PM sent.

content: Do you know how thick the cones need to be? I could probably make you a set of steel dies to form your own cones (you place a piece of copper sheet metal in between the dies and squeeze in a vice, then drill the hole through the cone using a guide hole in the die).

content: Quote from: eKretz on June 10, 2017, 03:51:57 amI'm not sure to be honest. I was hoping for a RF expert to chime inI have mailed blueskulls packagethe idea of having a die is very intereting. I wonder if you can make a broad band phase array system using a bunch of bicones...
