I just keep getting more and more awestruck of your work.

I got so far with my new design and realised that it just wasn't going to work. The wing area was going to be too small for the size of model...I always like low wing loadings.

Back to the 3 -views

Hi Peter,

Thank you for your very kind comments.

Thats a shame about your project.

Now that this build is drawing to a close, I’m already getting revved up for the next. I’m going to have a bash at the Grumman American Cougar that I have the plans for.
I have now photocopied the Nacelle from the plan and have decided that with a bit of moving of the formers and a bit of engineering work on the mount, I will be able to put a standard Dubro tank and still get a Saito 40 to fit.....just. I have also formulated a plan to extend the throttle linkages as, they are not in the easiest place to get to. I’ll start a thread on that at some point soon.

Cheers

Mark

Hi Mark

Well,it is just the startbof the design process. No point in continuing with something that one does not like.At least it was only paper wasted.

The Grumman Cougar sounds a nice project. I know that it wil be another astonishing build.

Hi Peter,

Many thanks for your kind comments. It must be annoying to get so far, only to shelve it.

Yesterday, I got the leading edge cap strips glued on after pre-bending them:

3c95d26b-7741-4932-91ef-d3dc952e6c35.jpeg

Then this morning I made a start on sanding. There is still a lot more sanding to do:

59dd2883-b29b-4a98-8995-9839e76c2e77.jpeg

Whilst the glue was drying yesterday, I didn't really have a lot to do, so I made a start on the throttle extensions for the 2 saito engines for the Cougar.

4180c346-bb71-4419-99b9-c6c089f92c2b.jpeg

Due to the placement of the tanks and the throttle servos, the throttle arm needs to be moved out by approx 1". I initally made up an extension out of brass bar. Before cross drilling and tapping for the grub screw, I weighed it, 17g. That is over an ounce for the pair.

I decided to change tack and make them out of Aluminium, although I am a little sceptical about the 3mm threads that will take the grubscrew. I'll worry about that later.

a45dd3b0-790a-4a04-8307-9db4a3c46441.jpeg

The brass one is complete, except the cross drilling, the ali ones are rough and still need the spigot making for the throttle arm. In this state, the ali ones on the scales together are 17g.

More work to do on those yet.

Today, I have got started on the tip ribs:

6cf67336-d9f2-4a6b-b780-e5bb70aa8fce.jpeg

I made up a couple of 'spacer' blocks, both the same length, to assist with getting the ribs in the correct position.

8aa7e3d5-09b4-46ee-b506-c995b20fce51.jpeg

Once these are done, I need to get on and make up the servo mounts and their associated mounting points in the wing.

Cheers

Mark

Hi Mark

THat is looking great.

It is far better to realise that I have made a mistake now while it is still just a drawing.

I have spent quite a while today going through my collection of scale drawing but think I may go back to non-scale.

I have plenty of other things I can do. I can write soemarticles to make up for the missing event reports...which I never read!!!

Hi Peter,

Thanks. Look forward to seeing those. I have finished your 4 stroke book, good read.

Yesterday and today, I have made a start on the wing servo plates and their associated mounting points:

I found a length of 1/4" square Cyparis in my stock, so have used this for all of the mounting points.

Cheers

Mark

Glad you liked the four stroke book.

Those servo plates look immaculate as everything else you do.

Thanks Peter, you are far too kind.yes

This is the total of todays work:

While the epoxy was going off on the servo rails, I got out the plan for the Cougar and the retracts I bought for it ages ago and set to work planning how I'm going to get them to fit. Not an easy task, but I think I am now on the right track to formulating the plan.

Cheers

Mark

Well over the last few days I have salvaged 3 articles out of books that where never published.

It may help to fill some pagesin the magazine.Mainly begginers stuff.

Also looked at dozens of 3 views, hsuddered and put them away again

Hi Gents,

John, thank you for your kind comments. Hope you are well and keeping safe in the current situation.

Keep looking Peter, we all need some of your modelling inspiration in these difficult times. I look forward to seeing your articles.

Nothing much done today, I had to go to work in London. Didn't want to, but key worker status meant needs must. At least the roads were quiet and I got to work in a closed Park outside in the glorious sunshine. Nobody much about, it was very strange.

Cheers

Mark

As the wing is now nearly complete, I decided today to get the holes drilled in the fuselage for the wing bolts. I spent a good amount of time setting up and getting the wing square then made up a small piece of 5mm tube to use as a drill guide to drill a 4.5mm pilot hole for each T nut:

50b98708-0850-4cb9-a56f-d8dc8324da53.jpeg

With all of the holes drilled out to 4.5 mm, I then gently opened them up in small steps to 6.4 mm. Then, using a steel bolt and a couple of washers, got the T nuts installed:

The wing fits well, and the 4 fixings locate it nicely:

a3aff1f7-e41a-4732-96f5-a291bf984ae0.jpeg

I then filled and sanded the wing, it now just needs going over with a fine sandpaper and it is finished, apart from cutting the ailerons free and hinging them:

Next, back onto the fuselage that needs a few more jobs doing, then its covering time.

Cheers

What to say that hasn't been said already? Cracking job Mark, the inside of yours is tidier than the outside of mine.

Hi Gents,

Peter, are you making any progress with inspiration?

Nigel, Thanks for your kind comments. My covering is going to have to be ‘on point’ with this one.

I haven’t done much today worth showing on Peggy Sue. Just painted the tank bay and inside of the cowl with the first coat of Solarlac. Whilst this was drying, I turned my attention to making the nose leg steering mechanism for the Cougar.

I have been thinking about this for a while and came across this video on YouTube **LINK** With nothing better to do, I had a go:

797a8cc1-338e-45e8-ba9a-78b24c47605e.jpeg

067ff014-16b6-4c03-900e-dccae89d8200.jpeg

9011bcee-d2de-4ecd-bc59-1eb8a874b8ea.jpeg

Still a bit of work to do at this, but it has proved the concept and I’m sure it’s going to work great. Even without the slider plate that the pushrod needs, there is very little slop. I will program my radio to turn off the noseleg servo when the gear is retracted, even though the design allows for it to still operate.

Thanks go to Martin Newell for his design.


Cheers

Mark

This is my third since my Reliant days and I still miss them. They could really move!

Luckily I don't do long trips these days.
