Is there another way to crimp aluminum sleeves without having to buy a $40+ crimping tool that I will only use for this one project?

Or at least is there a crimping tool that has another use?

I don't want to spend so much on a tool that will only be used once and will then be stored in a box until I die.

    Why not buy one on eBay, use it, sell it on eBay. Or use a regular tool rental shop? – RedGrittyBrick Oct 11 '18 at 12:50
  • I'd go with the tool rental. Things like that can be incredibly cheap to rent for one day, especially if the sales price is only $40 to begin with. – FreeMan Oct 11 '18 at 13:54

Just crush the thing with any tool you have around.

I googled the phrase "crimping aluminum sleeve without tool" to find examples of a child using pliers to get this done: https://www.youtube.com/watch?v=rMJETUcYNxg

If you can use a big vise to crush them down, that's probably the most 'controlled' way. Otherwise, use pliers, or get a hammer and chisel and dent the sleeve at two or three points with the chisel.

Plan on destroying one or two sleeves first just to get the technique down. Then, once you have one that looks right, really try to rip the wires out (to verify that you have a good internal connection).

I often use a thick nail set and drive two divots on each side of the ferrule on concrete, staggered from each other on opposing sides.

Simply crushing ferrules with a vice or Vice-Grip doesn't leave me with much confidence in the holding power of the crimp and tends to leave a less pretty result. Creating a zigzag path for the wire rope is more reliable.
