Working on installing new Cartouche seat cushion upholstery on new springs from Snyders. Made a spring compressor to get the edge of the new cover into the grooved channel on the bottom of the spring. What tool is recommended to crimp the channel closed? Both for the initial crimps to keep it in place and then the final complete crimp.
The grooved channel is on top in this picture of the painted spring.
I used "Cannon Plug" pliers because I liked the curved jaw and the plastic inserts to keep from scratching the paint. Regular pliers work too
I have a pair of these that I used when I did mine.

I took a pair of duck-billed vice-grips and bent the plates to make something that worked. It looked similar to the weld pliers above, but the jaws left the crimp a bit more oval than flat, but either would do it.
