Dear all

So after completing the Auxiliary tunnel I moved onto the auxiliary propulsion systems

Here are the parts being prepped and then the magnetic paper being cut out



At this point I realised that the "back surface" of these modules needs to be curved to match the curvature of the body of stage three. So this required on of the "flaps" removing (the flap to be removed is indicated below)



The best way I found of applying the "self adhesive" magnetic paper was by using a dowel to apply lots of pressure



Here they all with all the magnetic tabs attached and then the glued together parts



The magnetic tabs are essentially "hinged" and so till be able to fit to the curvature of stage 3.

Once all the outer parts of stage 3 are complete I will take them to y office at work and the apply the self adhesive ferrous paper to the body of the rocket in the appropriate places.

I must admit I do like the magnetic paper. Then I think magnets are really fascinating. I still find "Lenz's law" incredible to see and seems contary to physics (of course it is not!). If you have not seen it in action then take a look at the video below



I really like the fact that if you ever go on a vertical drop ride then it is exactly this that stops you. There are no friction brakes, too risky! Something like this (my listen to "top of the world" whilst watching)



Anyway I digress. Next up was the LH2 line feed. Here is how I proceeded



Adding the magnetic paper I found for me the best way was to attach it and then trim it "in situ" as shown



Then joining the various parts together



And finally the finished part



So remaining is the systems tunnel and the ullage rocket motors
