I'm not building a PS2, but I must thankyou Mark for the hints and tips on this build blog, not only have I learned technique from you, I have also learned to keep my building space tidier .

Hi Rob,

Many thanks for your kind comments. I find other people’s build blogs a constant source of inspiration. Keeping tidy is one thing that I need to work on, I often find there are tools all over the place and I spend more time looking for them than actually building.

Cheers

Mark

Cheers

Hi Mark.

I am fine thanks. I lieve alone and am happy that way. There are only four cases in Suffolk so I go shopping normally and our club field is only 5 minutes drive away...if ony the wind would drop.

Hi Peter,

That’s good to hear. I’m hoping to get some flying time in at the field. I need to get this off the board and get the Ballerina repaired first though.

Cheers

Mark

I did a little more this afternoon, after the bottom sheeting had set.
I remembered to drill out the front wing mounting bolt holes using the homemade drill thingie:

Then glued on the front pieces of the center ribs:

Once the top sheeting is on and the wing is off the board, I will be able to turn it over and ‘drill’ through the top parts of these and it should all line up.... famous last words.

Cheers

Mark

Glad to see you back at the bench, Mark.

... and 'hopelessly' neat as usual... wink

Take care of yourself, young man.

Cheers

Thank You Gents for your kind comments. Good to hear that you can see your bench again Peter!

This morning, I have started pre-bending the strips that make up the false leading edge. I chamfered the bottom, to match the angle of the lower leading edge sheeting, then made up a jig, soaked the end of the strips and the first one is now in the jig drying out:

d39bf651-fcc2-4f34-818d-b2a32727764e.jpeg

That jig will get used for the outer leading edge strips as well.

I’m now going to get out on my bike for an hour or two, while I still can and this is drying.

Cheers

Mark

I managed to get out and do 19 miles. 1 hour 23 minutes of bliss with hardly anybody on the roads and nicely ‘isolated’
Anyway, enough. I have got home and the first false LE is in and drying:

40df144f-517c-4869-94b9-0a0553d16f06.jpeg

It needs the top sanding to chamfer, and it’s going to need some work on the bottom at the tip, but it’s in and the other side is sat in the jig drying in the airing cupboard.

Cheers

I got the other side in this morning:

3ab74116-06fd-46f2-9995-bfa3cbf202d6.jpeg

and got started sanding the top of the first side down to chamfer. One of the little tricks I use is to cover anything that doesn't want the profile changing with masking tape:

Thanks Peter,

In between things today, I have got both tips of the top sheeting glued in. The compound curve made it interesting. I took a similar approach to Peter, but used a number of cuts to gently ease it into place:

Then I got on with one of the things I always forget and have trouble fitting - the blocks for the aileron hinges:

I also got out on my bike today and got my exercise ration in. 24 Miles

I find that just slitting along the grain works quite well at the tips but yours are really neat.

I often forget those hinge blocks untilthe tp spar capstips are on but at least I rmember before coveringthe wing.

I got my excercise by being in Wairose just after 8 am. (The oldies can get in at 7 but I told the young lady there was no way I was going out in the frost at that time.)

Then half an hour by my self test flying a model in the afternoon was enough for me!

Hi Peter,

It was a bit of a 'suck it and see' job, those tips. A little out of my usual comfort zone, but it worked out well in the end.

I got a little more done today, in between jobs. The hinge blocks are now all in and I got the port side sanded to profile:

Now, just the other side to bring in the same:

af6c66fa-34e2-4926-8e18-d716a5a81a2a.jpeg

I have realised that the cap strips for these will not be straight, due to the compound curves at the tip, but I am hatching a plan.

Cheers

Mark

I never even thought about the capstrips at the tip. Just bunged them on.

You are showing me how I should build!!!

But then I am just lazy.

I console myself with the thought that at least my models usualy fly well and don't fall to pieces in the air

Hi Peter,

If you built like I do....you would never get anything done. Every job seems to take forever. Having said that, I spend more time thinking than actually doing.
This build has been a joy. Can I thank you once again for your considerable efforts to our hobby.

Kind Regards

Mark

Very neat work Mark.

"I have realised that the cap strips for these will not be straight, due to the compound curves at the tip, but I am hatching a plan."

I must admit I would try a slightly thicker sheet capstrip and a sanding block. There is a lot to be said for adding a bit extra and carving or sanding back (it's my default tactic for any compound curve)... assuming I even thought of it in the first place!

Hi Gents,

Thanks for your comments. Below is how I attacked this problem:

This is a straight piece of cap strip:

58cac49a-a769-40ba-b555-a2b50f3568d7.jpeg

You can see that due to the compound curve, it doesn't fit correctly at the tip.

I first marked the interface of the two balsa blocks with a pen, then overlaid a piece of greaseproof holding it to the wing to follow the compound:

5e8528fd-7cb0-47de-9eae-9dcc471cba64.jpeg

As you can see below, it is far from straight:

541f6769-8e54-49e5-85a5-afe986488541.jpeg

This was transferred onto a sheet of 1/16:

cf929747-a923-4c8c-a2fe-ede51fd01125.jpeg

Then using a circle cutter, I marked out the other curve:

6055cc96-d6d1-40ad-b1e9-6fd21da350f1.jpeg

This was then glued into place:

ca551ea3-438e-4293-b3b4-8c3ca92a1c9c.jpeg

Whilst I was at it, I cut the strip for the Aileron capping and both strips for the Starboard wing. Its not perfect, but it will do. I'm going to use transparent covering again, so I need to keep my building neat and tidy.

Cheers

Mark
