One has to mark the shear web cut line, for which I used... jip, the laser level again :D

This is the result of the 2 cuts.

In fact, the smaller section at the top I did again, as you can see there were lines visible from the cut (this refers to the last picture as they seem to load bottom to top). The bottom section was practically flawless and is close to perfect.

I did not take another picture of the final product from the front :( but there is one from the back... (and this first and 2nd picture is actually of the replaced top section). This rear one was to check the alignment of the 2 sections, as they will be glued later. Once again, laser used for this! It is a remarkable tool with a 1000 and one uses :wink: (used normal A4 paper for levelling the bottom and top section).

Yesterday I finished the last of the upper engine mount supports :D :D :D
This means I've finally finished all the engine supports and I can now move on to the gear humps and the vertical stabiliser. I'm milling ideas around on how to treat the gear humps to assist with rust prevention, as I'm a little worried about this. The top of the humps will be covered by the fibre glass, so no concern there, but the bottom end, which is part of the cavity in the fuss, is open to air and moisture and this is the area I think I'd like to treat. I'm also considering putting a drain of sorts in there at the lowest point maybe...
I'll share what I find when I have more worthwhile information...

:idea:
What I've found with these layups are that there is a lot of resin flowing from the layups as you are doing them. I like to keep my work clean and tidy and as I'm a novice with composites, I had to make a plan to keep the area clean! I used packaging tape initially, but later I decided to use peel ply. I cut ample sections and put this around the edges of my layup work. The idea is for all the spills to run onto the peel ply, which I can the later simply rip off again. This should leave a neat and tidy work area I hope, but the proof is in the pudding. Will tear it of tonight to see if it works as I had hoped.

PS: The peel ply option is not great when the resin forms a dam! If you wipe it away occasionally so there is only a thin layer of resin it works just fine, but it means you need to work pretty clean too!

Just to share a little useless information...

Total time spend on my build this far is 43 hours, so about 950 to go, but at my tempo maybe more like 1450hrs to go!

2014/05/04:

I started on the horisontal stabiliser and the vertical stabiliser, as I'm waiting for a Dulux product: Hammerite Rustbeater, which I want to use as a primer on the landing gear humps. My gear humps seem to pic up a lot of rust, so I'd like to give them some protection, as they are not something I'll inspect often.

The assembly of the vertical stabiliser on the provided drill outs was quite easy. Thought I'd get the front vertical spar in place as a foundation to work from.

What I found was that the cut out on the vertical front spar at the bottom as indicated on the part (the round gap needed for the elevator cables) was indicated a little higher than what worked on my setup. I've already cut the hole, so I had to make it elongated to match the fuss bulk head hole.

So levelled the fuss, sanded the bulkhead and the front vertical spar, aligned the front vertical spar using the laser and floxed it in place. I'm super happy with this part, it is a 100% perfect piece of work.
My flox mix did go exothermal, but only in the cup. The portion I worked with did not exo at all and thankfully worked perfectly.

2014/05/05:

My assembly of the vertical stabiliser did not line up perfectly on the provided drill outs. I battled, but always seem to have a gap between either the vertical front spar, or the leading edge of the wing skins.
I mailed Russell for advise, as I thought of moving the skins back or adding a flox filler. Russell suggested the flox filler, or moving the horisontal spars up, so the gap to the leading edge reduces.

I left the stabiliser with the gap issue to ponder the situation a little more. Decided to get started on the horisontal stab foam cutting.
My son, Emil helped me with cutting the horisontal stabiliser, as he proved to be the most talented hot wire cutter in my family. We cut the right hand tip section and it came out pretty well.

We cut the horisontal stabiliser right hand mid section, which also came out well.
I find that the smaller the parts to cut, the harder it is. The person with the bigger cut dictates the speed of the cut, which sometimes causes the person with the small cut to have to slow to a halt and this causes visible lines in the cut.
The cutting is quite and art, but we're getting pretty good at it now.

2014/05/10:

Decided to get back to the vertical stab. I levelled the fuss on all axis and use the level to get the stab horisontal spars level and kept adjusting the height to see how the gaps I had reacted.
After a bit of tweaking I got it near perfect and the gap between the 2 horisontal spars I kept a 120mm at the base on the vertical spar. This should work well for the horisontal stab to slide in there.
After all the fitting I marked the holes I'll be using for the final setup with a black permanent marker.
