Chapter 9 – Brake Line Install

I started today by continuing the design on the belly air scoop for the ram air intake.  I spent a good amount of time researching the intake nozzle shape & checking my options for what bell mouth-shaped aluminum intakes are available for sale online.  So far I haven’t found exactly what I’m looking for, so I’ll keep looking as I continue to dial in the shape, design & configuration of the air intake scoop.

My main focus today was to get down to brass tax to answer my #1 burning question at the moment concerning my final brake line connections: stainless steel or Nylaflow? (both of which I have on hand).  What I don’t have on hand is a flaring tool for the 3/16″ stainless steel tubing I have on hand ($$) or the fittings I would need to connect up the Nylaflow into my current configuration ($).

The first thing I needed to find out is if the stainless steel tubing would even fit into the channel tubing I emplaced on the aft side of the main gear fairings.  Well, the stainless steel tubing, being a small diameter, was easily bent by hand and with just a little bit of effort & cajoling I got it to slide into the fairing channel.

Below is a closer view of the inboard side.

Knowing that the stainless steel brake line can be fit into place easily enough, I then pulled the trigger and ordered yet another tube flaring tool that can handle flaring 3/16″ stainless steel tubing.  I don’t have the model or specs in front of me but when I get it in hand & use it I’ll give you a report on how it works.

Below is a shot of the outboard side gear with the stainless steel brake line sticking out.  As you can see, there’s plenty of tubing to work with which will allow me to most likely create a service & anti-stress spring loop at the hell hole side of the tubing.

I threw together an ACS order along with the flaring tube order which I’ll finalize tomorrow morning.  Again, tomorrow is Monday so it will be a school day & night, so no building will get done on the airplane.
