Thread: An Introduction to the PSSA 2020 Mass Build Project
25/02/2020 10:01:19

Hi All, thought I would pop this here, this magazine is currently on sale, got mine in Tesco, but I'm sure its probably in WH Smiths and other outlets. Its approx 160 pages of Sabre history and information. Its a good reference for lots of the detail needed in the build: panel lines, nose shape, tail shape and the tailplane/ fin rear fuselage shape! It covers all the marques including the Fury and Sabre dog. Plus its a good read!

( I think its availability has been mentioned in a blog - by John Tee in Tony's build blog, so apologies if this is a repeat).

Hi Dirk, they look superb, very clever idea and a great scale item!

Thanks Martin and Gordon for producing this helpful pdf, It'll be fun making up the tanks.

On the subject of tanks, have a look at this little bit of craftsmanship from three Sabre drop tanks:

Hi Robin, I would go scale anhedral ....or at least take a view... maybe somewhere midway between scale anhedral and flat? But not flat. The anhedral wing is such a characteristic of the Frogfoot it would be great to retain it.

Hi All, thought I had better update my blog! Various combinations of events in Dec/Jan contributed to massively slowing down my build rate, but I'm back to moving the Sabre along, and hopefully I'm not too far behind!

So, the fuselage is now pretty much planked apart from a small topside area, which I have left to allow me some access until I'm totally happy that all is good inside. I'm reasonably happy with the planking, many tapered pieces were cut and let in, and many angled planks were needed, all great fun and rewarding when it comes off! I did'nt manage to do any substantial sheeting in the end - I think the widest planks I managed on the bottom were in the order of 10mm.

I've removed a large chunk of former F6, then cut and sanded back all overhanging planks front and back and then given the whole fuselage a first pass rough sand.

In addition I have started to make up the tail group, fin, finstrake and tailplanes. I'm going down Phil's route with the tailplanes and using three laminations ( ie 1/8th trapped between 2 x 3/16ths).

I'm also now starting to think about the cockpit area and deciding how deep I can go with a pilot figure, I suspect not to far!

Couple of shots to share...

Hi Chris, that nose profile is really getting there now. Once glassed and painted it will look great. Roll on the Sabre dog!

Hi Chris, I'm still watching also, various factors including illness have held me back a little recently but all good to go now! Great progress and great application of Andy B' sanding method.

If the forecast (XC weather) stays as is, I'll be down on the 2nd.

Sounds like a plan... Count me in! I'll bring cake to go with Andy's offer of coffee & sandwiches!

Thanks Phil, hope you get your Sabre on the go soon.

General question to Sabre builders out there, has anyone tried any fuselage sheeting or part sheeting? or is everyone planking all round? I think there may be some part sheeting opportunities in a couple of places such as the rear underside or forward of the canopy. I'm not there yet but may look at it. Any comments appreciated!

Thread: Sabre build "Gotchas"
30/11/2019 19:15:33

Hi Martin, this is a very minor one, not really a "gotcha" but thought it may be worth adding.

The parts come with an occasional minor triangular shaped "pip" on their edges (presumably where they are released from the parent sheet). It's no problem at all to sand them off prior to use. A surface that perhaps may get missed from this sanding is the inside square section of F2 and F4 where the battery box sits on the internal flat portions of those formers. Easy job to do before the fus is jointed. Its no great shakes if it gets missed - just helps with a flush/ tight joint between battery box and formers.

Hi Chris & Mark, thanks for your comments.

Ref the planking - I added 10 planks on the first half before adding the second half in sections. Each plank is 7mm wide, they were all butted together, but distributed above and below the fuselage centreline. ( I started on the centreline and worked down by 5 planks, then back to the centreline and worked up 5 planks).

I reckoned that the combination of planking and stringers, plus adding the top spine (which doubles the spine thickness) would minimise any warp risk. I think its further helped by adding the substructures of the second half, one by one, allowing drying in between. Anyway - I don't think its warped yet!

I'll carefully plank the non planked side, then do alternate side planking until I'm done.

Hi All, I've moved the fuselage on a little more. I have been worried about the major "glue up" required to join two part planked fuselage halves in one go. This involves, applying glue along all the major joint lines of the top and bottom spines, and along all the former joint lines, gluing and fitting the wing bolt plate, then aligning and clamping, all  in one gluing "event". I did'nt trust myself to get this all square and had visions of glue everywhere and an out of line fuselage!

So I tried an alternative. I part finished one fuselage half to the point of adding 10 planks (7mm wide). I then built the second half, section by section, onto the part planked first half. I starting by adding the straight top keel, then worked front to back, adding each sub structure in turn and allowing drying between each stage. At the end I added the stringers and the small part bulkheads of F3 and F5.

Photos hopefully show all!

Nose and battery box added, after top keel

Central crutch and wing bolt plate, I adjusted the plate to move it back approx 5mm to sit against F7

Hi Chris, Great progress with the wing there. Regarding the waffles... you've not just chopped up your wing jig and grilled it have you? smiley

Good tips there Chris, here's another that may help for trimming false leading edges (and false trailing edges).

Take a steel ruler and sit it immediately behind the false le and sat on top of the ribs, with a scalpel cut through the part of the false le that sits above the ruler, then cut along the ruler with the blade flush and flat on the ruler surface. This leaves you with only the thickness of the ruler to plane down flush. Cut from in front of the wing. Staged photo shows what I mean ( wing in photo already trimmed).

Hope it is of some help!
