Good tool, but must be hand drilled to accept bearing installation cup
Good tool, but you have to drill a hole in the bearing installation rod to accept the cross bolt that locks the bearing installation cup onto the rod.

I'm not sure what they're selling.
Gimbal extractor works. One of these guys needs to come down here and show me how the installer works. There is a driver for the bearing with pin but the driver rod itself has no hole like shown in the picture. How do you miss that?

Good value, very useful for go kart wiring
Size: 100ft, Style: 6C-18AWG
It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.

Beware! Very thick wire
Size: 50ft, Style: 6C-18AWG
I'm not going to ding the product, because it's totally what it says it is. I didn't look at the diagrams to see that this wire is 10mm wide. Almost half an inch. Waaaay to thick for the project I needed it for.
