Week 96 - Horz Stab securing pins and wires

Hours to date: 974.25

Now the weathers picked up I've moved back onto the tail area.

First job is to install the securing wires that hold the horz stab pins in.

Once again I have copied Pete's modification here as he says the factory method doesn't make for the most user friendly result.

So I bought some Stainless bushes (with a 10mm inside diameter) and drilled out a hole just big enough to accept the securing wire with it's plastic sleeve.

I then superglued these into the tail and covered the whole lot in flock (as per the instructions).

When that had set I pulled out the wire and then cut away the plastic that was left inside the bush. (using a scalpel).

The wire goes in very easily and reliably every time now with this mod.

After that I bonded in the wire security hooks with flock and a layer of glass.

Next job is to make a hole in the horz stab. Then pour flock through that hole into the cavity I have made earlier (see earlier post from last year - done before bonding in the root ribs). The horz stab is then pushed onto it's ali tube all the way up to the rib and the flock is left to set inside the cavity thereby securing the pin.

As you can see below I also bought some composite securing threaded posts.

These are available from a company in Germany called R&G Faserverbundwerkstoffe. (Try pronouncing that after a couple of beers!)

They are just stuck on with flock (which oozes through the holes) and then a layer of glass and provide a great way to secure wires, P-clips and the like.

Pete uses them extensively on his Twisters.
