John A's Sabre build
Steve McLaren replied to John A H's topic in PSSA Mass Build 2020 - North American F-86 Sabre
Very impressive work again John. But It's too late for me, I've already added the top wing skin. So where did I put those magnets? -

Hi Amy, I have a very tatty example of this model. I didn't know it was a Cambrian version until I saw this thread. It was passed on to me by Steve Howarth a couple of years ago. I was planning to convert it for PSS but it's a big job, and there are other things getting priority. So far, I've only got round to removing the remnants of the bent undercarriage, etc. It's in a bit of a state, and needs a lot of work (wing skin is delaminating in places, tailplanes and fin are both loose, it only has half a rudder, etc, etc.. But if you're interested, send me a message, and I'll send you some pictures and more info.. Steve

Wow! Does carbon paper still exist then?! Very clever approach John! And fantastic progress for 1 day! -
Nice work Harry. I'm interested in the tank drop mechanism. What size servo do you plan to use? and does 1 servo do both tanks? I'm trying to visualise the geometry of pushrods meeting the servo.

Sciabola or Italian Sabre
Steve McLaren replied to Alan Gorham_'s topic in PSSA Mass Build 2020 - North American F-86 Sabre
Thanks Al. Very informative. I will refer back to this later. I think I will try to do more of mine by painting this time. I will see if I can get hold of some of this Oramask 810. I assume that for those of us who don't, have Vinyl cutter, we could put it through an inkjet printer and cut out with a scalpel? -
Uh-huh!?!? You've lost me there Mark! Are you sure you have the right Steve McLaren? It's not that bloke that used to manage the England football team is it? He probably has more aerobatic skills than me.

HaHa! I shall try to be more systematic Chris! I fixed the jig down to the bench Chris, by cutting and pre-drilling about 16 small spruce blocks and glueing them to the sides of 8 ribs, then tacking through these with some small panel pins. I notice that most people are glueing their jigs together, but I didn't bother. Mine is just pressed together and then tacked to the bench. Mainly because I wanted to be able to dismantle it and keep it, but also because I thought it would be sturdy enough like this. You just need to check that all the jig ribs are lying flat on the building board before you start to assemble the wing. I realise now that the reason I had trouble aligning the wing on the jig is because I had far too much excess on the lower skin. This obscures your view of the jig and the plan and makes things difficult. If I did it again I would reduce the extra wing skin to about 1mm all round.

Well, I've made a start on the wings. I was very impressed by how well the jig went together and how well it sat over the plan. I found it a little tricky to line up the construction of the wing over the jig and plan, due to the height difference and parallax errors, etc, but I think I've got it close enough. I noticed the same problem as Harry with the height of the jig at R1, so fixed it the same way with a strip of 1/16th balsa. Maybe there's a reason for this gap? I must read some of the blogs of the other guys starting on the wing! I've never built a wing this way before, and was a little apprehensive, but it seems to be going pretty well so far and I think it should make the process of achieving the correct wash-out, a lot more straight-forward than many other methods.

Nicely done Harry. I'm hoping to catch up to this stage today. I made the wing skins last weekend, but no progress during the week. I can see that they're useful, but why do you have so many lead/acid batteries??
-
It reminds me of your A4 Skyhawk Harry, which looked Ace. So I'm hoping I can get the same effect. I hadn't even spotted the yellow/black chevrons - but they can't be so difficult can they? - just need the right width of masking tape!
-
I have searched around and it doesn't look like anybody else is doing this scheme. If I'm wrong and you've already chosen this one, just let me know and I'll find another!
