Seat sling

[Rex Havis]

I need to know the type of knots to use when lacing the seat sling. I plain on using a 1/8" nylon & polypropylene card as the lacing. If this will give me a problem please let me know.
Also I'm going to replace the bushings in the gear and the control fittings. I know this information was given a few months ago and I thought I had printed it off, but I'm unable to find it, if I did. I need the infromation on the size of the bushings and where I can purchase these parts. Thanks Rex

Rex:
I used two pieces of extra long 1/4" nylon braid in a "X" lacing pattern (like you'd use to lace up your boots) with a square knot at each end to lock it in place.

Re: Seat sling

Airtex Products, look them up on Google or Trade-a-Plane, they are in NJ or PA, I forgot which.

Re: Seat sling

Wish I could remember where, but I was told not to use Poly cord because of the way it burns and the gasses it gives off when it does. I was told to use Cotton cord. I found it easier to tie and very nice to work with.
Before anyone asks, yes, I did question why fire safety on the cords was a concern since if the seat cord was on fire, the plane was probably in a flaming free fall and I would be LONG gone! It may be silly, but you aren't supposed to have flame gassing materials in the cockpit, even when you have 12 gallons of gasoline over your knees. Rules don't have to be rational.

That said, I would not be that worried about it if my IA was OK with it. I trust him more than what someone I can't remember said.

Re: Seat sling

I am a non expert here, "but I am an old Navy guy"! Cotton will stretch a lot less then the man made stuff so will need less make up later.

PS: River experience says old cotton cloths line is what you make it, poly stuff is always up for interpretation after the fact.

Re: Seat sling

Have this to say about poly, I had a small rollup (kinda like rolled into a ball) hammock that I used when out hunting to take a break in when I lived in Fl and didn't want to take a nap on the ground, the hammock was cotton the ropes on the ends was poly.
There is a real funny feeling you get in your stomach when the bottom drops out and you freefall when the rope breaks, thank god I was only 3 feet up, really makes me shudder that I had used it 30' up 2 weeks before.

Quoting a friend, "if you can't tie a good knot, tie lots of them" You should see how he secures a load on a trailer.

Re: Seat sling

Hey Bird! Which failed, the cotton or the poly? Cotton rots after it gets wet and poly rots in sun light.

Re: Seat sling

The poly failed and it never got wet and was never in the sunlight so go figure, I do know that you won't see me on the end of poly anymore.

Re: Seat sling

I have had the best luck with black Dacron. No UV, stretch, or rot issues.
1/8" should be heavy enough. Start with a Bowline Knot and pull the strain
against it.

Re: Seat sling

Bob, can you tell me where I can get the black Dacron rope also any information on how to tie a bowline knot would be appreciated.
Thanks Rex

Re: Seat sling

Black and also green Dacron rope is often found at Amateur Radio web sites because it lasts a long time as antenna guy line.
You can find a bowline in your Boy Scout handbook if you don't see it online first.

Re: Seat sling

Yep find a pic then think: After you make the loop, think rabbit out of the hole, around the tree, and back in the hole. This is how I was taught the bowline in the boy Scouts a short time ago; 50 years or so!
