Well, I made an interesting discovery today.

My local hobby store carries K+S hobby metal. Their 9/16 tubing makes 
almost an exact collett for taking up the space between the FSJ1-50 and 
the LMR-400 crimp style N connectors. A 3' piece cost me almost $4 with 
tax.

So, I cleaned the tubing with a file, tinned it, and I cut an inch of 
tinned tubing.
Then I prepped the FSJ by stripping back about an inch and a quarter of 
the jacket, tinning the shield over the exposed area, and making the 
center conductor stick out about 1/8".  I filed down the solder since 
the FSJ is a friction fit into the brass tubing.

I soldered the pin to the center conductor. It's a bit loose, but it's 
workable.

Then I soldered the brass tubing into the N connector, easily done.

Then I inserted the prepped FSJ cable into the brass tubing, and just 
flowed the solder in the collett.

Now add a piece of heat-shrink and you have a N connector on the end of 
FSJ1-50, for about the price of a PL-259.  

I think maybe it would be a good idea to add another piece of larger 
tubing on the outside of the connector sleeve for strain releif, but I 
don't think it's strictly needed.

So, now I am not so worried about obtaining those connectors.
But by replying to my own email in thread, perhaps someone else will 
find this when they need it.

If anyone's interested, I can do some pix for the RB site.

KC6ETE clear!
