What is the process of getting from the wood and black varnished fus plug to the glass fibre moulds. Could you or anybody please explain or describe these few steps please. Thankyou.
I covered those steps in my "80" Dynamic Build Thread". If you're interested.

Control surface prep.


I got all of my surfaces together and have the appropriate sized aluminum tube. I also made sure I have plenty of braided sleeve for the job. I use that stuff on all of my planes so I keep plenty around.

Next is to make a series of cuts to remove most of the foam in the area I want to put the tube.

Then I wrap a piece of sandpaper around an appropriate sized tube and sand the rest of the foam back to allow room for the aluminum tube.

It is very important to sand as much of the foam away from the skins as possible to insure a good bond. I sometimes use a sanding block on smaller surfaces but my favorite tool for the job is the dremel attatchment shown.

I use a heat gun and heat up the labels on the tubing and remove them. Then I use laquer thinner to clean off and residue.

Then I use 120 grit paper and sand the entire tube. Once it is all sanded, I clean it again with laquer thinner.
All tubes sanded.

Next I push on the braided sleeve until it covers the entire tube. Then I wick in a drop of ca and give the sleeve a twist and hit it with kicker. I can then cut it with scissors. Then I pull and pull until the sleeve is tight and in tension on the aluminum tube. I then ca and twist the other end. Once I hit it with kicker I cut it loose and move on to the next tube.
I always tape over the control surfaces to keep resin off.

I accidentally threw out my 3" roller so I had to go with the 9". Oh well.

Next I roll them out with resin and and work the resin in very good with my fingers then set them aside. Then I take a brush and wet out the area the tube will go and place the tube inside. Then I weight the surface down on a flat surface covered with plastic. These particular tubes were just a little on the loose side so I mixed up some resin/chopped glass/and black pigment to get a better bond.

Once the resin has set up I take off the tape where I want to put a wiper. I use a special blue tape for this purpose. I will have to get a part # for those interested. The thing that is good about this tape is that it seals very well wherever you stick it. Therefore it works better than anything else available for taping off straight stripes and such. Anyways, the tape also leaves a beautiful polished finish on the resin that dries against it. It is also kind of thick and plastic so it holds a good radius and doesnt fold.

Then I mix up some resin/chopped glass/cabosil/microballons/white pigment. It needs to be thin enough to flow out once you lay it down but thick enough to not run all over the place. I guess about the consistency of goop?

I apply a small amount of filler in the corner where the tape is coming off the skin and then use an acid brush to sweep out any air bubbles. I then put a larger bead to finish up.
