Bob and Others,
A few years ago...many years ago...I was in the same quandary of how to crimp a ferrule to wire.
I did not want to go the solder route as a lot of feedback stated that this was not the best for many reasons. Then I remembered an old farmer trick for making a "die". I scrounged around and found a regular hex nut of suitable size, cut it in half - remember the threaded inside diameter will decrease - and used the "nut die" over the ferrule in a vice to crimp; of course I rotated it to equalize the crimp all the way around. Sure it left thread marks but they were covered with shrink wrap. BTW if you don't want the marks you could ream out the nut. AND if you want longevity you could use grade eight material.
To tell the truth this was used originally on my 1954 Case tractor rebuild and worked so well I adopted the procedure to my CH 701 build a few years back. No problems.
Just thinking !!!

Well folks,
Will soon need to crimp a number of large AMP terminals to some large wires, and been playing around with a Harbor Freight hydraulic crimper I had for a while.
I decided to write this report part to contribute, part to solicit thoughts and feedback.

Thanks for sharing your experience and
observations with this tool. I purchased
one about 10 years ago with similarly
high expectations. I found that the die
markings bore no real relevance to
the real world.
I too accomplished a few crimps onto
various un-insulated terminals and
found that with a little fiddling,
a FEW combinations of terminals and
wire could be artfully accommodated.
Wound up taking the tool back 'cause
it would NOT do the crimps most
needed (4 and 2AWG). Too bad. The
hydraulics were fine but the die
set was essentially useless.
I considered making new die sets
but unless I was going to seek a market
for production, return on investment
was poor.
In answer to Rich's suggestion, YES . . .
soldering is a perfectly reasonable
alternative . . . but without vice grips.
