TEXTILE HARDWARE AND A NUT

At the moment I am doing details. Details but details are important and time-consuming.

On Exlex I secured the lunch-box hatches by screws. Some people say that takes to long time. I say I dont mind spend ten secounds to obtain a well secured hatch. Pictures below show how I secured the 30 mm long M8 bronze nuts.

The nut is embedded in NM-epoxy and secured with 24 pieces of carbon rowing. A bolt clad in teflon-tejp is inserted in the nut to prevent the epoxy to get into the screw-threds.

The epoxying of the nut is done with the lid in place and the bolt in the nut. That guarantees that everything is aligmented.

The bolt is remowed. It have done its duty. Epoxy is all over the place but not in the screw-threads.
The epoxy is removed. The nut is countersunk. That helps the screw to find the threads.
This is the start of hardware for my safety-belt. A three strand polyester rope is wraped around a piece of Divinycell insulated with pastic film.
The polyester rope is saturated with NM-epoxy. Polyester fibers and epoxy love each other as you may have noter when you get a drip of epoxy on you clothes.
The picture shows an Idea for a textile padeye. It is extremely light. Weighs next to nothing and takes glue exelently. Its a good idea for a small boat and even for a bigger one.
The reverse side of the padeye. I use only the mantle of the polyester string to make it flatter. Spectra and Dynema does not take glue well. Those kind of fibers are very slippry and polyester is plenty strong. This padeye can be done with very simple tools. Here for the experiment I am using plywood Tufnol and carbon fibers can also be used. The knot is a Zeppelin knot. I think they look great.
This is a fitting I will use for securing the four 13,5 kilo batteries.
Some of the textile fittings. The ones at the bottom is for the safety belt.

To be continued…
