bungee cords

[Bob Waldron]

Mark, If you have a tool to loan, I am in need. If you have not already committed it to anyone else, I would sure be happy to pay shipping both ways and then some. Thanks. Bob Waldron

If anyone is still reading I have a small issue regarding the placement of the cords.
Printed instructions do not distinguish but videos, drawings and photos give at least two choices. And one makes more sense than the other.
Input would be helpful before I commit to the installation. TKS.

I put on the cables first, then the bungees, they only fit one way.

I heard someone here saying forget the cables..more damage potential to the cords..I really have no idea ..but do see how a cable swinging around ...or stationery could help fray the bungee Anyhoe following this post...it would be helpfull to have a picture as to how all should lay...correctly. I am going to be faced with this soon as well.

If you route the cable right (like in the drawing) they won't rub on t he bungees or slip over them to rest on the diagonal tube (which will tear up the tube if a bungee fails).

TKS to Tim and Hank for your responses!

I understand and have the drawings of the cables. I think I get how they are installed so not to rub /chafe the cords. When in place they are loose and if between the cords have wiggle room during normal operation.

But that wasn't my question. In one tutorial video it states the outer ("shock") cords go on the outside and the inner *shock* cords on the inside. This is also - if you study the hidden lines - the arrangement the drawing represents.

None of the printed instructions make reference to this one way or the other.

But in at least two photographs I see it done another way, with the *outside* (NOT outboard... it can be confusing) cords running *inside* the "inside" ones.

UNLESS this is about CHAFING- as in cord-on-cord, I see it as preferable *because* it provides for more balanced loading between the two pairs.

IF you stretch the pair that are *already* stretched the farthest by making them *straddle* the second... you're putting the max load on them and the minimum on the second. I've already been told Taylorcraft has "stiff" landing gear. I'm at least looking at a way to dial that back to something more 50:50.

The photos are from two members, one who makes the bungee tool. Both show the way I am describing as a preferred (alternate) way:

Trying to figure out how to word this and not make it MORE confusing. The first bungee to go on go closest together on top and bottom. The second bungee goes further out on top AND on the bottom. In the photo the cable in NOT correct. If it works its way outboard it can go around the diagonal tube on the gear which will make a real mess of the tube if the bungees fail! The cable should be trapped between the steel tube and the bungees in the small triangle formed by the bungees and the tube they are wrapped around. Hope that is clearer than mud! ;-)

Mark: Thanks for the link and thanks everyone for all the information. I should, after three months finally get my old BC12D flying this week. However, I still have a gripe list of 18 items, most minor but do enjoy working on the list. Again thanks.

A/C Spruce has a full line and reasonably priced.

Hi, To be clear, Aircraft Spurce is a reseller of SBC's product line, they do not manufacture the product.
You can purchase directly from SBC but due to manufacturing batches and timing they might not have the part you need in stock when you want it.

SBC is the sole source manufacturer in the USA and worldwide and if they were to ever go out of business we are in a bit of a pickle. It is a small and old family business with specalized equipment.

Hope this helps.
