		  Hello Group

I was trying to fabricate this cable, but having trouble in step 2. The exposed braid refuses to suck up the molten solder. The moment I put a soldering iron ( a standard radio shack 35W iron) the solder freezes up and won't melt and flow. Have enough flux applied to the braid, not sure what I can do to get this tinned.

any pointers would be highly appreciated

Thanks

What kind of solder are you using?  Some types melt at a higher temperature.  The wire might not be getting hot enough or made of a metal that does not readily accept solder.  What kind of flux are you using?  Solder made for electrical connections usually has a flux core and extra flux is not needed.  Flux made for plumbing is acid based and will cause electrical connections to corrode and fail eventually.

Can you attach a pic of your actual setup (coax, iron, solder, etc)? 



Misc thoughts: Iron tip must be clean & tinned with solder, for efficient heat transfer to the work. Also, some 35W irons have very low mass tips, and can't keep up with the heat transfer into a large 'sink' like braid. 60/40 or 63/37 rosin core electronics solder; Electronics grade flux; and last, this is a long shot, but make sure your coax is copper braid shield and not a foil shield. There are some coaxes that have an aluminum foil shield instead of braided copper.

I was putting in the cable for a new build and after reading the description again, postponed this till I actually test the performance.Thanks to all for the pointers.
