Great neat work there Simon. I've tried using the "bitty" foam before for wings, and found them to form soft hollows after having the skins pressed on. Don't worry about having more than one PSS project on the go at once - by last count I had 7.

Hi Andy, 7!! Thought I was pushing it a bit at 2 laugh. My problem is finishing off a project, always seem to jump onto the next one a little early:

Original mass build JP, constructed this year, not 2014!! I will get it finished next year, honest!!

Do you think it's worth continuing with the 'bitty' foam? I have used it before on a constant chord wing, almost Wot 4 thickness, and it was okay. I'm not 100% on this new wing, due to the airfoil/wing taper. Shouldn't be any problem to cut a new set in a more robust foam(?)

Cheers,

Simon.

Can't hurt trying I guess! I was making fairly thin wings and it wasn't great, perhaps the Sabre will be ok.

Hi Andy, I'll have another look at the foam cores after Christmas, it's really busy here until the New Year!! I was planning on using 3/32" balsa to skin them, with a carbon/foam/carbon spar and maybe a little glass cloth under the skins(?).

Oh yeah, they're not for a Sabrewink.

Cheers,

Simon.

Currently working on 4 PSS models swapping places on the bench Simon, you have nothing to worry about! yes I try to get them all at the same stage of the build and work on them as a collective.

That JP looks stunning and needs to see some air. laugh

Hi Chris, thanks for dropping by. My big resolution next year is to try and manage my free time better.

I find it's very easy, to let yourself get distracted with another aircraft you'd like to build!!

Free time is at a premium now until the New Year, so probably won't get too much done on the Sabre. Still keeping up with everybody else's builds thoughyes.

Cheers.

Simon.

Well, after a longer break than I'd expected, I've finally managed to put a bit of time in on the Sabre build this last week. Mostly bringing the right wing panel up to the same point as the left.

Next job was to sort out the torque rods. They're quite 'beefy' so I had to remove quite a bit of material from the root trailing edge. I used a combination of permagrit rotary files and needle files. The pictures should show the process:

Next job was to check the movement of the rods by dry fitting the assembly to the wing:

All looking good so far, so onto the next step of attaching the torque rods to the false leading edge with a few drops of superglue. When dry, I then used some Hysol to glue the trailing edges on, with a small amount smeared over the torque tubes that extend into the aileron section:

So, the last job I tackled this evening, was to spot glue the ailerons onto the wing, which allowed me to sand them and the wing to a reasonable level. The wingtips were also laminated with balsa cement, so really need to leave them overnight to fully harden. Hopefully should be able to get the wing glued up over the weekend and finally off the jigyes

Let's hope the next update doesn't take quite so much time.

Regards,

Simon.

Great to have you back at the building board, Simon.

I hope to have a go at aileron torque rods as well later on, but still have a 'solid' pondering about them...

Cheers

Chris

Good to be back Chris.

Your 'Sabre Dog' is progressing very well indeed. Fantastic woodworking skills, I'm sure she'll be a 'cracker' when completed. If you have any issues regarding torque rods, I'll do my best to help out. I noticed 'The Boss' (Phil) is also using torque rods, on a low winger like this, I still think it might be the most robust method of moving the ailerons. We shall see.

Regards,

Simon.
