Brackets

Leading edge side

All non-quick disconnect cable ends use cable bushings and retainer washers vs the original rivnut/custom spacer/retainer washer assembly.

Both root quick disconnect positions use original rivnut stud brackets.

Both mid position quick disconnect positions use re-built rivnut kit brackets where the original long barrel rivnut is drilled out and replaced with a short barrel stainless rivnut. The salvaged retainer washer is used on the flying wire on the outside position.

1. upper root - original bracket
2. lower root - new bracket*, no rivnut, drilled for 3/16 AN bolt.  Flying wire in the outside position.
3. upper mid - new bracket* with straight rivnut stud.  Flying wire uses cable bushing and retainer washer in outside position on bolt.
4. lower mid - new bracket* drilled to 3/16 AN bolt.  Flying wire uses cable bushing and retainer washer in outside position on bolt. Negative wire uses cable bushing and retainer washer on inside position terminated with nyloc nut.
5. Upper outer – new bracket* drilled to 3/16 AN bolt.  Flying wire uses cable bushing and retainer washer in outside position on bolt.
6. Lower outer – new bracket* drilled to 3/16 AN bolt.  Flying wire uses cable bushing and retainer washer in outside position on bolt. Negative wire uses cable bushing and retainer washer on inside position terminated with nyloc nut.
7. Upper tip – original bolt mount through leading edge spar.
8. Wear prevention washers of .025 Lexan are installed between the strut and bracket steel on each side of each strut/bracket.

* the new bracket requires ¼ inch spacers on both sides of the 1 inch strut to achieve the required bracket gap of 1.5 inches. This enables a complete disassembly by getting rid of the permanently captured flying wire originally part of the rivnut/bracket assembly and specially tooled bracket and custom spacer.

Trailing edge side

All 3 of these brackets are drilled to 3/16 for AN3 bolts.

1. Upper root – original bracket, new short rivnut
2. lower root – flying wire outside positions
3. upper mid – original bracket, new short rivnut, fly wire in outside positions
4. lower mid – new bracket drilled 3/16 with flying wire in outside position and negative wire inside.
5. Upper outer - new bracket drilled 3/16 with flying wire in outside position
6. lower outer - new bracket drilled 3/16 with negative wire on inside

Materials and sources

Brackets – Local job shop fabrication. 20 gauge stainless, laser cut from author’s Draftsight dwg files created from original plan parts. Files available in “files” section of Easy Riser Yahoo group.

Retainer washers – stainless, sourced per original kit part

Cable –

Cable coating -

Nico press sleeves – zinc plated sleeves will corrode. These must be tin coated. I always get these from an authorized Nicopress distributor since they are a critical component.

Shrink tubing -

Strut saddle bushings – Leading Edge Airfoils. If these become unavailable, plain nylon fender washers could easily do the job.
