Great guys, I'm glad this thread helped some folks. I've been looking for a crimp tool that I could do these connectors for some time, all the "proper" tools are from $400 to $900 for a single connector pin type! I realize they will yield a perfect crimp every time, but who has $3000 or so to stock the toolbox with all the tools for Lionel and MTH? I know how nice it would be, but I can take a few extra seconds to do a double crimp with these tools that's needed to properly crimp the contact.
I have several connector specific AMP tools DB and MTA connectors, and the really expensive kit for ribbon cable connectors, and they work great. Of course, I don't do any of those anymore, so they're just expensive paperweights nowadays. I'll stick to the $40 tool this time.
