Crimping Furutech FP203R spades

Same answer as in June of 2020. It looks like the link from then expired but this is the same tool I linked previously and still use, and it is not too expensive. Amazon has quite a few different models here. Still using with those crimped FP203 spades, for probably around 10 years now, and and they still holding up just fine.  However, I wouldn't argue with soldering them.

Belt and suspenders; a simple battery cable lugging tool - Anchor sells one - u use a hammer. Advise a bit of silver contact enhancer and solder.

Also… i believe as many ( but not all ) that lower mass spades sound better and w reasonable binding post pressure will result in a gas tight connection…

ymmv

Amazon link for what I used on them.  You need leverage.

I bought the hydraulic crimper for the Furutech spades. When crimped the barrel moves between the left and right opening. The crimped barrel looks like my drawing with flat pressed sides. 

Does this happen with yours also @mitch2 ?

Edit: I tried to upload a pic but I can’t figure out how. 

Hard without a picture but the result is hexagonal, the same shape as the dies.  There may occasionally be a bit of the spade material that squeezes into the edges where the two die pieces come together but I have never had a crimped spade come apart or fail in any other way.  The end result should look sorta close to the Cardas forged connection.
