yeah its very tight, when you set it you need to heat the connector in tweezers with thermal contact between the wire and connector for it to melt so the strands can slide in, very tricky, but if you 1/2 fill the barrel, melt it, slide a flux covered wire in there to wick up the solder while in the barrel, then slide it out half way and feed more solder and reinsert it, it works reliably, but you need to be quick with the foot pedal to keep the flux from being used up, a micro applicator needle helps to reflux the part taken out of the barrel after initial melt, then get solder ready so you can quickly heat and feed then release heat and cool.. would not want to try this with a iron.. after I melt solder in the barrel no matter how careful I am I can't get the strands to go in there unless the solder is molten, there must be a thin coating on the wall just enough to prevent it from going in
The stripping works fine with a cable strip tool, if you cut wires out it becomes easy, the hard part is the one you mentioned, you just need to carefully try it on a few pieces to get the correct blade depth, you can hear the blade of the stripper break through then yank it off
I should have put heat shrink on there to thicken the wire up to the hole a little before I assembled all of them but I did not think of it for some reason
I can still put some electronics silicone in there with a syringe I suppose
I hate trimming off strands to make wires fit, so janky
Kinda think a indent crimper might work there too.. the barrel seems very thick but the fit is so good that crimping might work. have you ever tried a 4 indent crimp on a center pin meant to be soldered? it does not have a spec but I thought to do it and then do a tug test by hanging weights off a pin vise connected to the crimp, but I don't want to waste a connector.. I just bought ALOT so maybe I will try one since there will be connectors to spare
If anyone wants to think of settings to use on a 4 indent crimper with a linear adjustment for diameter on a Amphenol 31-202 then let me know, I 'restored' one of those tools a few months back but have yet to crimp anything with it, or at least tell me if its potentially destructive since the wall is too thick
