Got to mess with it today. I didnt want to waste my lugs that im going to use for the install so i used the ones that were slightly too big. Tested it out with the big ligs and a lil peice of 4/0 Knukonceptz. I used 3 different dies, 4/0, 250mcm, 300mcm. The lug im testing is a tinned copper ILSCO 350kcmil, but its a lil too big for the 4/0knu. It wiggles slighly. The size im using for the actual build is the same lug but 300kcmil, fits perfectly. I have another thread somewhere about test fitting a bunch of electrical grade lugs for the 4/0knu, just search 4/0 knukonceptz and my thread should come up somewhere. Heres the pics.2CC73B9B-685A-4F26-82BC-32BA7DF18FC9.thumb.jpeg.c97ebe0a9c92402f48395ae0268029df.jpeg8ACDAC70-226F-4C77-80A9-5B98CED8A2EC.thumb.jpeg.deddb5803d16956f5d6c17df4a0bb5d3.jpeg

 

Heres the first attempt 4/0dies. Way too small causing the wings lol. Also included a pic of the comparison of the 4/0knu wire behind the 4/0 die. You can see the rubber jacket around the wire and imagine the jacket being a perfectly fit lug, seeing how much the die would compress it all.

Those dies are too small for that lug. 

You shouldn't be making wings on the sides like that.

If its a 350 kcmil lug use a 350 mcm die or there about. Granted your using a lug that is like 3 sizes up higher than the wire gauge. 
A 200 kcmil lug should be close to fitting the wire, I wouldnt go any larger than 250kcmil.

A good crimp should look like this.

Yup i was just testing it out, just to get some pics up. The last crimp was almost good, but becuase the wire was small it didnt fill out perfectly. I should be able to post the last crimp pics now. Have to wait a few mins between posts to upload.

Hate to say it, but your best using one of your correct sized lugs (if you have one) to test and get it right, before you doing it on the car and you get it wrong. Thats why you should always order extra lugs. At least 10 more than you planned to use because you never know when you might want to do some additional wiring that you didnt plan for.

edit: thats a lot better!

and if your your worried about the right size crimp being a tad loose you can always do it a size smaller. However use the correct sized dies on the correct size lug first, then go back and recrimp with a die that is the next size smaller than what you just used. This way you wont have some giant lips hanging out the side of your lug.
