Leaving the question of why some clever Chinese tool maker doesn't supply US die sizes for the US market. (shrug)

Or, perhaps close is good enough and all the sized dies business is nonsense?
Trust me , I had my reservations about these hydraulic crimper’s , I have a couple of crimper’s that have standard dies that have not worked well in the past so I thought I would give this one a try , for the money , why not. I wanted to make sure these crimps would handle the current I was going to put through them ,300 amps, so I cut open a couple of them to take a look at how well it was working. My tests showed full engagement and fusing of the strands, no voids! So maybe that SAE die thing is nonsense ? Best money I have spent in a while .

Regards John

Re: FTZ battery lug crimper

I contacted sailboatowners.com to let them know I didn't receive instructions. Since I posted this morning, I've also noticed that some of the lettering on the dies is illegible. Something is goofed up. I have a feeling this was a return to someone else along the way and SBO didn't know it. They are sending me another one today and are taking this one back.

Good service.

Re: FTZ battery lug crimper

I have this one:

https://www.amazon.com/Greenlee-K09-...eenlee+crimper

All the dies are both numbered for their nominal wire size and colored. You can't rely only on the wire gauge markings on each die because different lugs come in different thicknesses. The Ancor starting lugs are made of thinner stuff and they crimp fine in the corresponding numbered die. The FTZ lugs for the same wire size are thicker so you need to go up a die size. In that case, the color coding on the lugs tells you the proper die size.

Bottom line, go with the color markings on the lugs. If there is no color marking, go with the nominal wire size.

Re: FTZ battery lug crimper

I also bought FTZ heavy duty lugs, as these will go from the 125 amp inverter/charger directly to the battery.

Update from sailboatowners.com, who are being very helpful. They opened another box, before sending it out, and found it also doesn't have instructions, nor was the die lettering very crisp. They said the tool is now made in China, it's used to be made in the US. @Maine Sail may update his recommendation.

The Greenlee isn't cheap but it's very good. Made in Germany, FWIW.

FTZ 94284 Calibration

#1 Set the left die to "A"
#2 Set the right die to "C"
#3 Open handles fully
#4 Close handles until the "A" die and "C" die first touch
#5 Do not close handles any further (dies just touching)
#6 Measure the distance between the handle centers at the handle ends
#7 Distance should be 14" - 16" center to center
#8 If not 14" to 16" turn the Allen head adjusting screw (on right handle side of tool above sticker) clockwise to widen the handle gap and counter clock wise to narrow the gap.
#9 Hint closer to 14" and the crimp is on the low side of adjustment (less tight), closer to 16" and the crimp is tighter.

Thanks Maine. Starting measurement was 20 inches! Here's a pic of the quality, which is the same die setting in one of your pics on your website. I've also included a pic of the cause. SBO has offered to replace it, with one I can read. Although, they say they are all fuzzy letter stamping.

There you go Minne, Maine beat me to it...

On mine one letter is also fuzzy, but you sort of get used to it... Interesting enough when I first saw Maine Sail's article the cost was under $150 now it is up to $180 - price going north quality going the other way....

In any case, its a good tool and the cost per crimp on mine is getting lower everyday.

Re: FTZ battery lug crimper

For what it's worth, while installing our Maxwell windlass in 2006, I found that connecting lugs to the cables needed was much more easily and neatly accomplished by using a "SwageIt" hand swaging tool:



The "SwageIt" was also far less costly than a crimping tool.
