Anvilbrother 0 #1 June 3, 2014 Eq consists of Wings risers, navigator 280, slinks, silicone risers, dacron lines with a total jumps on lines and bumpers about 75-100. Im a big guy with faster openings, I had hard links but they were damaging the slider grommets, so I switched to slinks, and the silicone bumpers. The issue I am having is the brake lines are rubbing and cutting a groove in the silicone bumpers, and fraying the brake lines on openings. Its almost like the lines are "sawing" back and forth on opening. The wear marks line up right where the brakes are set leading me to believe this is only rubbing on opening, especially since when brakes are released the lines do not come close to the bumper at that point. Also some of the outer D lines inside the bumper are rubbing and getting frayed a bit. The only option I can think of is adding a "sacrificial" line of the bigger size (1250lb?)dacron over the top of it where it wears, and bar tacking it in place. This would only slow the problem down not eliminate it. Im not sure if its happening due to assembly or material issues, or my faster opening speed of about 132mph. edit to add the reason we installed the bumpers was due to the slider coming down and damaging the line attachment points at the slink. Mostly on the outer lines on the rears. Any thoughts on what to do? Thanks Postes r made from an iPad or iPhone.

Zlew 0 #2 June 3, 2014 Never seen bumpers and slinks before. If you really want something to protect the slinks, have you thought about the pirate hats that come with Slinks? http://www.youtube.com/watch?v=fBX0ed2yE50&feature=player_detailpage#t=205 Edit to add- they may sit too low on the slink to give the protection you are looking for.

Cantoral 1 #3 June 3, 2014 Maybe you can try with "webbing bumpers", normally they are used with rapide links but I think they will work fine with slinks...are "low profile" and will protect your lines from the sliders grommets... Quote Share this post Link to post Share on other sites
wildcard451 0 #4 June 3, 2014 ...why do you have silicone over your slinks? Why not just take them off instead of other fancy solutions? Quote Share this post Link to post Share on other sites
Anvilbrother 0 #5 June 3, 2014 In my post I stated that the slider grommets were coming down and slamming on the line attachment points and was damaging them at the slinks. The cloth witch hats that come with them were not helping, so we stepped up to larger silicone bumpers which fixed the line attachment point issues, but now the brake lines are rubbing the silicone bumper.

Anvilbrother 0 #7 June 3, 2014 I was advised the bumpers were vinyl not silicone bumpers and are sharper on the edge and do not stretch as much. I am going to first replace with silicone bumpers and see if that fixes things. Postes r made from an iPad or iPhone.

councilman24 36 #8 June 3, 2014 In image left is vinyl (what you have). Brake lines have been carving those for 30 years. Silicon is the middle. Softer and won't damage the lines as much but will tear easily. Fabric are on the right. Perhaps a better choice. All of this are usually used on french links. On slinks nothing is used if you want to pull down your slider. (make sure your toggles have nose hoods) or the Slink Cover (pirate hat, witches hat, cone, etc) that come with main slinks if you don't want to pull your slider down. That's usually enough. I usually don't see much damage to the lines from grommets with slinks and Slink covers. I'd try the factory covers first. They allow the slider grommet to be below the line attachment points. The silicon or cloth bumpers will hold the grommets next to the lines, just in a different place. BTW silicon covers were used because the were easier to get at the local home depot in a size for 3.5 or 4 mini french links.I'm old for my age.

pchapman 261 #9 June 3, 2014 If we're doing photos of the varieties available, then there are the other style slink covers - see attachment - which allow the slider to be pulled down unlike the 'witches hat' covers. Not sure what name to give them? But they do give some protection to the lines where they attach to the slinks, if the slider is slamming down to that point.

councilman24 36 #10 June 3, 2014 And those work with both.hard.and soft. From Precision right? At least the ones I have. I.always considered them more line.orientation aids, rather than bumpers. But may be best for OP.I'm old for my age. Terry Urban D-8631 FAA DPRE Quote Share this post Link to post Share on other sites
pchapman 261 #11 June 3, 2014 Not actually sure who sells them?! Easy enough to make at least. Yes I'd call them link protectors or covers rather than bumpers. A fast moving slider can still go past them. Quote Share this post Link to post Share on other sites
councilman24 36 #12 June 3, 2014 It's been a while since I got a new precision reserve but IIRC they came with the reserves to go on hard links to keep the lines in place on the link. Some tell me what the right story is. I'm old for my age. Terry Urban D-8631 FAA DPRE Quote Share this post Link to post Share on other sites
