Hi Chris,

Many thanks for your kind comments. Yes, Peter’s latest build looks very interesting.

Tonight I have got the top brace and both top spars in:

Once that glue dries I am onto the 1/16 vertical grain spar webs - a job that always seems to take me ages.

Cheers

Hi Chris,

I should have taken a photo of the tip rib to show what I was blathering on about. Unfortunately, both tips are now on and it’s not coming off the board until the ‘D’ box is finished. I’m hoping it will be OK, we will have to see.

You really can’t have a build without Gaston making an appearance👍

Cheers

Hi Chris,

Hope you are well mate. Good to see Gaston back making an appearance on your build log.smiley

I made a start tonight on the wing tips. Now, because I fitted the rear part of R6 along with its small cap strip, the tip didn't want to sit properly. I carefully took a small strip out of it with a scalpel. I also fitted a small piece of 1/16 x 1/4 that i had sanded to a slight angle onto the bottom spar, so that the tip will be 'sandwiched' between the spars - the plan shows a gap between the bottom spar and the tip sheet.

I made a start tonight on the servo mounting plates. They will follow the same design as I did on the Ballerina. The ones I did on the Ballerina were made by hand, these will be a bit more precise...
1/16 ply, cut and sanded to size, then clipped onto a 1/8 blank that is held in the vice. Followed by 10 minutes machining and here is the result:

Last few ribs in, followed by a few bits that I forgot on one wing of my Ballerina build (I had to cut the t/e sheet and ‘bodge’ it back together). Gussets and the ply plate for the aileron horns:

The ply plate is a 1/16 piece to fill the cap strips, followed by a 1/8 piece. Same set up as my Ballerina. That is the only rib that I have fitted the lower cap strip to.

Hi Chris,

If this is anything like your other builds, it will be a work of art.👍 I look forward to following along.

Not got much done over the last few days, as I have been busy with work.

I have managed to get the last couple of ribs in, so that I could get the paper tubes made up and in for the servo leads. Now that is done, all of the other ribs can go in.

Hi Peter,

You would have the next half dozen designed and flying at the speed I build at😂 I work on the basis of a little bit every day and at some point it will be finished.

Only got 5 ribs in today.

Hi Gents,

No problem at all. That looks like an interesting project.

I got a bit more done on the wing yesterday. I have made the 1/2" a full rib on both sides, and cut the front off so that I can drill for the wing bolts, it should all become clear later:

Thanks Gents for your kind comments.

No real building done today, but I have got my set of cutters finished off. I also made up a ‘ferrule’ that I am planning on using to cut the top wing sheet for the wing bolts. It slides within the 9mm cutter and takes the 5mm cutter through it. The 5mm will then be used as a guide to ‘counterbore’ 9mm down to the ply plate:

Hi Peter,

Hope you are well. I haven’t found an easy way of doing that. I do wonder if a sandwich with 1” blocks of foam between each rib would work, then pattern at each end. Not an easy job.
A few photos from this morning:

Not got much done in the last couple of days. Been busy at work. I have managed to get the slots cut for the spars though. Then split them down, got the slots added to the templates for the 5 inner ribs, then back together and slots cut for the front ply plate and the additional wing brace:

Still a bit to do, I need to cut out R5 and R6, and put the holes in for the servo leads, but the ribs are nearly done

Hi Peter,

Many thanks for your comments and for the plan earlier.

Im well on with the ribs now. One of the reasons I like the ‘sandwich’ method, is that the ribs end up very close to exactly the same.

Before stacking them together, I go around the edges of the ply and ‘paint’ them with a permanent marker pen:

37f9d247-6878-45b5-a89e-3964bd917e3e.jpeg

This is then used later as a ‘gauge’ to show where needs sanding some more, and where it is finished.

Then stacked together and sanded to final shape:

Now, after all that work comes the scary bit... cutting the slots.😬

Right, for a bit, I thought I was going mad. It does indeed say not to drill the ply wing hold down plates:

It looks like you have been ‘edited’ Peter😂

Hi Peter,

Many thanks for the plan. I did think it was not your normal way of doing things. Never mind, I'm sure it will work out. I will get the mag out again tonight and have a read through.

Regards

Mark

Yes, the sheet should go over the leading edge and then the leading edge cap covers all of it.

Same with the tip,the sheet tip goes to the outline and just strips of thin sheet round the edge.

PM me with your email address and I will send you PDFs of the original drawing.

The way I mark the bolt holes is this.

1) I fit the Tee nuts into the ply plate when I make the plate.

2) I have short lengths of wing bolt sharpened to a point (A pencil sharpener works well) These are screwed into the Tee nuts so they just protrude a bit.

3) I line the wing up vary carefully and then press down. This makes and indentation in the wing. Drill through and open up carefully..

Hi Peter,

Thanks for your kind offer, PM Sent.

That was the way that I did the holes on the Ballerina wing. I have followed the 'words and music' in the magazine. If I remember correctly (and its a big if) it says not to drill the holes in the plates and to use the wing to mark out their position once the wing is complete?

Cheers

I got a bit more done last night. Starting with a couple of, what I see as errors on the plan. (Maybe Peter can comment on these):

The leading edge sheet is shown butting up to the false leading edge in the sectional view, I'm sure, knowing Peters other builds, that this is incorrect. - Although it is shown going over the false leading edge in the plan view.

Before:

9b99bc2f-b389-4c15-a58e-230fdf1189ba.jpeg

After:

ed08b37b-5e2c-4349-b88c-4da22759858d.jpeg

The other one is the wing tip. The very tip is shown as being butted up to the tip, I'm thinking the sheet should extend to the tip and a couple of 1/8 strips on either side, as per the Ballerina

Before:

4471bd0f-15be-411b-bfe3-d7c5d42da27c.jpeg

After:

bd84ecc0-e73c-48d2-b954-36d6e1d35b80.jpeg

I then got on with cutting out the blanks for the ribs. I have gone with a sort of hybrid sandwich method for this one. All of the blanks were cut about 1mm oversized to the pattern, that way I could make best use of the balsa without too much wastage:

41fac957-784c-4d3c-b6ab-ece82bac5e0e.jpeg

0418c3ae-62b4-4452-8d69-3bc3860fcc00.jpeg

That is: 3 x 1/4", 2 x 1/2" and 16 x 3/32" that just now need the holes drilling and they are ready to sandwich together and shape up.

I've been thinking about how I'm going to get the holes for the front wing retaining bolts to line up with the 1/2" rib, because, once the ply plate is in, there will be no means of centring the hole to get it to line up. I may have a cunning plan. We'll see.

Cheers

Mark
