I have "The Jigs Up". It works great. They even have an updated version now that allows you to rotate a deans connector both ways. The nicest thing about using a jig vs. a pliers with rubber band is that you don't mar up any of the bullet connectors.
The jigs subtracts heat from the connectors you are welding (not the case of the deans) and this is a bad thing. Worst 20$ spent in rc equipment.
How can plastic draw heat from the connector? All I use it for is deans. It allows for a quick, clean joint with having to hold a hot wire with your fingers. If you feel it is useless I think you may be using it wrong.
[Look at it this way, a vise is just a large heat sink.
I have some soft plastic jaws for my vise. Also, I have a small clamp on vise (what I was referring to) that has a plasticy type of coating on it and it works great for bullets that will transfer heat.
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.
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.
