You certainly can't beat your own job, but it needs to be done right with the proper tools, a trick I use and I know others do too is once I remove sheath I tin the whole braid,allow it to cool,then cut it exactly within a mm or so with a plumbers pipe cuter, I then remove both that and the dielectric and tin the centre conductor/s, that's the cable prepared,
if nickel plugs especially I file the tip cut out and the edge of the body solder holes,then tin them all whilst held in a vice,if you overfill the holes you can suck it out with a solder sucker. If you overfill tip tinning it,cover body holes with fingers (teflon tips help wae this one) and heat the centre pin with iron,give a hefty blow at cable entry end excess solder will come flying out and fuck up any carpets it hits,so do it over an empty ashtray or board or something the missus won't inflict serious bodily harm on you for damaging, you can use this cheap and dirty technique to reuse plugs too or reft shorted plugs, get the rg213 into plug and solder tip and solder holes,chaeck for no shorts with multimeter, I suggest a 50-100w iron for 10.3 mm cable, you wan't that job done as fast as possible. if you overfill body holes you can file the blobs down for a neat finish with jewellers file,
Next job attach to antenna, tune, seal up with self amalgamating tape and as you guys love to say,fergetaboutit, because it will last years. And with some practice and careful meeasuring of where to cut through tinned braid you can make consistent cable lengths within mm of each other,it gets easy with practice.
