Thanks Nigel,

Still some work to do on the cowl, but it is coming along. I had some time off work today, so got started on the wing.

First job was to trace out so that I could build the other half:

The lines are much easier to see than the photo shows.

Then I got on with making the hold down plates:

Finally, I made up the patterns for making the ribs. I like the ‘sandwich’ method:

A little more done. Got the rudder and elevator servos in and the snake inners made up onto ball joints. Now starting one of my least favourite jobs, shaping the cowling:

Hi Nigel,

That looks beautiful mate. Well done. Don’t start thinking about the ‘dark side’ as Bob alludes to 😂😂😂

Bit more done, but I went off on a tangent. I got fed up with cutting myself on the hole cutting tool. Up till now, it has had a piece of electrical tape wrapped around it, so I set up a piece of Ali bar in the lathe and using my homemade knurling tool, set to work making some small handles:

They are just stuck on with loctite retaining compound. I still need to make up a 9mm and a 13mm, and the tops still need facing off. They will all get done together once I change the Chuck back over to the collet chuck.

I made them long, so that they will fit in the collet chuck to resharpen if needed.

Cheers

A bit more done over the last couple of days. I've got the snake outer holder pieces made up. It has taken 3 iterations to get the snakes somewhere near straight:

Hi Peter,

I had a couple of failures with that. Now in the scrap box for future use.

Bit more done today:

Bit more done last night and today. I made a start on the cowl:

There are lots of compound angles on the side pieces. One of these makes getting them close easier:

36e57711-cc84-4af4-80d4-332ae64b22bf.jpeg

As you can see, this gets used an awful lot. There are not many pieces of the build that doesn't see this at some point or other.

The side pieces are close, but not perfect. After about half an hour of fettling each, they are near enough.

I then proceeded to drill out all of the holes needed for fuel tank fill, exhaust pressure, crank vent, needle valve and low end needle. I used my trusty cutting tool that I made ages ago. Its much easier to do these whilst they are not attached to the airframe:

Hi Peter,

I don’t like using the starter on my Ballerina, I’m always careful that it’s not flooded, but, normally, it needs the starter to drag some fuel through.

Bit more done today. Throttle linkage made up, so now I can get on with the cowling.

Hi Gents,

Nigel, your welcome mate 😂 Still a bit to do on the linkage. I like a dead straight run, so I will open out both formers at the ends to allow the snap link through, with just the centre former holding the rod in place. Photos to folllow.

Peter, I had my concerns about the tank position on the Ballerina, but, having flown it , the Saito doesn’t seem too concerned about the tank being a little high. I thought that I would have a lot of trouble with it flooding after the first tank of the day, but having used it, it seems to only need the starter for the first fire up, (not being able to prime it as the carb is inaccessible) once it has been run once, it will flick start every time after.

Cheers

Hi Paul,

Many thanks for your kind comments.

Yes, I have gone for an inverted engine. The set up is exactly the same as my Ballerina, and, exactly the same as the plan. Tank in centre of engine mount, it is a little higher than the centre line of the carb, with the engine inverted, but I have had no problems with the Ballerina. If this engine is anything like the one in the Ballerina, it’s just going to want to run and run.

Normally, the Ballerina engine will start first flick, every now and then it gets to see the starter😂

I’m considering putting a remote glow on this, but I have had no real issue on the Ballerina, the Saito plug is angled rearwards at about 45 degrees, so, as long as you are careful, your fingers are never too close to the prop at start up.

Cheers

I Thanks Peter. I do try hard to keep it neat and tidy.

I have had the afternoon off work today, so lots done. Starting with a trip to my LMS (Gliders at Newark) for some Superphatic. - they didn’t have any, but I spotted this:

ca9bb736-3909-47d2-a35b-b99f5a5731d4.jpeg

I have a bit of a fetish for tools.....

dd789889-9d6a-4cdf-b19a-48d3feacc7a9.jpeg

What a great bit of kit. I can see it’s going to be the ‘go to tool’ for engines and servos. I did some testing with it this afternoon:

82891d6b-85d3-4e34-aede-9a9e82b0150c.jpeg

Then I got set up to start building the cowl:

9483d223-5d6c-4c12-b75a-822fc26aee56.jpeg

I was just about to start, then realised I still needed to make up and drill for the throttle linkage. I made this mistake on the Ballerina, it’s much easier to sort out without the cowl in the way.

Hi Nigel,

I have been watching your build with great interest. Beautiful neat and precise build. I will be interested to see how you get on with the set up/flying as I have plans for a Grumman Cougar that is getting further up my build list.

Keep up the good work

Hi Nigel,

Many thanks for your kind comments.

Been out and done a little bit more. I had a bit of scrap light ply that was just the right size for the nose ring, so I got it marked out and ready for routing the hole. I had made up a spacer tool when I built the Ballerina, so I cut out the hole 35mm to fit the spacer tool.

754ee20e-9040-43f9-b996-549fe2a8a93b.jpeg

This follows Peter's cowl build sequence, it works really well and gives a great finish:

The inner hole of the spacer is a snug fit on the engine prop driver.

Cheers

A little bit more done tonight. Port stringers sanded down, then Fin glued into place. I used a couple of spare engine bearers to hold the fin straight.

Glued in with normal Aliphatic, so I'm going to leave it overnight to go off before I move it about too much.

Hi Peter,

Many thanks for your kind comments. I have done a little more tonight, just pottering about with it.

Sanded down the Starboard Stringers to rough finish:

f14cb115-d95d-4b8c-afce-7cbb8b790cd4.jpeg

Then sanded the fin to rough finish. I spent a little time sanding a vee into the rear to match both sides, but I went a little too far, so added a couple of little filler pieces. The fin sits nicely on the 1/8 filler piece above the vertical stab slot.

I really need to clear the bench and get on with repairing the Ballerina, after my mishap with the hedge a couple of weeks ago, but I'm enjoying building this too much.

Cheers

Hi Peter,

Yes, anything that makes things easier is good in my book.

Bit more done tonight, starting with sanding down the filler block and filing out a slot for the top stringer. The photo below shows me using masking tape to protect the wing seat from the sanding bar. It leaves a very small step, that is sanded down very gently once the tape is removed.

4c5c8c32-856d-4584-b989-873467d1d161.jpeg

Stringer installed:

cc0ed5b5-208b-4920-b409-a00c8b186051.jpeg

And sanded down to blend in:

db59682e-a961-423f-8516-fb3c292bd98f.jpeg

Then blank made up for vertical stabiliser. I like to add a small piece of cross grain at the top to help stop it from warping:

Hi Peter,

It is a bit OTT, but the mill was sat doing nothing, so it got used.

I have got a few ‘bits’ done the last couple of days. I got the wing seat sanded to final finish, F2 was a little short, so I put a 45 degree onto a piece of 1/8 light ply, then cut and fitted it.

5190dae5-0ff8-49bb-9413-247095d87085.jpeg

I also made up a couple of tiny fairing pieces to blend the rear sides in at the top:

1b334630-3c9a-4fce-9801-794d6a09dd3a.jpeg

And made a start on the filler piece at the rear of the wing seat:
