I drilled holes in a 2x4 for my bullet connectors.works great.
Yeah, wood is a very poor conductor of heat. I had planned to do that myself. But then I would have a holey piece of wood that someone else would likely throw away (my employess like to toos out the useful stuff and save all the junk). Maybe if I find a nice cut off I will make one and label it well, and put a disclaimer that I will castrate anyone who touches it.
I use one of these and I also have a set of helping hands. Between the two of them, I'm set for any job. I like the KillerBee jig when soldering extensions to servo/ESC leads.
As the one with the baddest soldering station in this forum, a vise with plastic/rubber jaw pads is all I use for EC5, Deans, bullets and whatnot. But that "The Jigs Up" is a pretty cool tool.
Wow I've never seen anybody have such and issue with soldering before. Try soldering a side by side ni-cad pack back in the day. I don't know about others but after so many years and countless deans and other solder jobs I have never used a jig and never will. Y'all need to man up them sissy fingers! Lol
