Last centimeters?  No Problem.  I use a MIG welder.

And here I don't even reuse PL259s.

That's why I have so much junk out in the shop, or suffer from that TMS 
malady. TMS = Too Much Sh...er Stuff.


BTW I just put new filter in my all shop fans/filters.  Instead of 
$300-$500 for an all shop fan/filter, I purchase inexpensive 20 X 20" 
window fans.  Then tape a 4" X 20" X 20" pleated, 1 micron furnace 
filter to it.They move a lot of air and two of them do a really good job 
of keeping the air in the shop clean.  I had used 5 micron filters and 
they lasted about 6 months even with the welding.  I'm trying the 1 
micron which work very well, but I'm afraid they aren't going to last 
anywhere near 6 months and they run about $34 each.

So far, I use carbide inserts on fly cutters and face mills and there's 
not much to salvage once those are worn out.
