I posted this in my build thread but I know not everyone looks in there so I posted it here so more of you will see it... If you have any large cable wiring/crimping to do, these are worth the money...
I was holding off crimping all of the big stuff (4ga and 1/0) until I ordered one of these hydraulic terminal crimpers off eBay last week.

Harbor Freight sells this for 70 bucks. I got it for <55 dollars and free shipping...
I got it today and tried it out on a 1/0 cable terminal. I can say it worked very well and I am glad I waited to do these crimps until I got this tool...
Here is the lug I am going to crimp. As you can see this is pretty big. The tool comes with dies to do up to 2/0.

Excellent investment and it makes some nice looking crimps. I am going to look into hard mounting it to the bench. It gets kind of busy trying to hold the cable in place while trying to actuate the hand pump on the crimper.

I clamped the lug in the vise and tested the crimp. It will take a lot of force to pull the lug off...
I finished up the crimp with some heat shrink and called it good...

Of course I have at least a half dozen of these to do on the big cables and as many or more on the 4 ga. stuff. Should be fun now.
