pressuremedia 0 #1 May 16, 2009 Done a search here but nothing came up. My dropzone needs to come up with a good/not overly expensive/reasonable wearing solution to slider bumpers for our tandem sigma canopies. We have tried various plastic tubing - some is too soft and wears VERY quickly, other is too hard and I believe it would wear the steering line in the tight junction made between the slider grommet and slider bumper 'lip'. tried webbing around the lines/link and the steering lines wear through it pretty quickly. last method was homemade along the design of the black bumpers for slinks but was a pain to make and even more of a pain to attach with fat dacron lines. So what are people using then? Please share your experiences. Jim Quote Share this post Link to post Share on other sites
riggerrob 643 #2 May 16, 2009 We just use the stock, clear plastic bumpers that Strong Enterprises supplies with every SET400. They last a long time when wrapped around Maillon Rapide #6 links. Quote Share this post Link to post Share on other sites

It can be tempting at time to go with nothing, however, Ive seen tandem links side-load and lock canopies into linetwist. Quote Share this post Link to post Share on other sites

pressuremedia 0 #6 May 20, 2009 Very bad idea of using slinks with sigma mains - as others posted the width of dacron lines leads to VERY fast wear on the slinks. We also got wear on the tip of the risers where the brakelines were coming through the slider grommet (even to the extent we had to ground a pair of risers).

My tandem mains are Icarus (Precision, Icarus/Precision, Icarus Spain), all vectran lined. I was not aware of any heating problems, but it would seem that it's not an issue with vectran anyway.Experience is what you get when you thought you were going to get something else.
