Phil Beard Posted July 15 Share Posted July 15 Decided for the start of retirement that I wanted to build a large scale PSS Sabre, so asked Martin Gay who along with Gordon Studley produced the short kits for the 2020 PSS Mass Build, if he could from that kit develop a larger version and from discussion with Martin I decided on a 1/6th scale Sabre build. Many thanks to Martin for undertaking this on my behalf and from the attached photos you'll be able to see the amount of balsa and ply wood parts that have been CNC routed as the short kit for both the airframe and the jig required to produce the wing. Photos 1 to 4 shows the balsa and plywood parts required for the aircraft itself with amount of material required. Photos 5 to 6 shows the plywood parts required to make the wing jig. Photos 7 to 8 shows one of the 6 drawings that have been supplied for the build. Note the ruler in the photos to give you an idea of the size of the parts. 3 Quote Link to comment Share on other sites More sharing options...

Phil Beard Posted July 16 Author Share Posted July 16 Decided to start building the starboard side wing jig today. Just done a dry run with the parts over the plan as can be seen in the photos. Have also cut alot of little balsa blocks to fit at the positions where the parts go over each other just to make it that little bit more sturdy (These aren't shown yet as not been glued together yet). These have been cut from the scrap balsa for parts N1 to N3. 2 Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted July 16 Share Posted July 16 Hi Phil, I have noticed that some of the jig pieces need adjusting for any future kits! Please confirm: J1 needs to be extended to R5a J2 needs to be extended to R10a J3 needs to be extended to R15a J4 needs to be extended to R4a and R19a J5 needs to be extended to R8a and R22a J7 needs to be extended to J17. If you need the jig parts replaced please let me know. Martin. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 16 Author Share Posted July 16 Martin, I should be ok. I'm going to make the jig more sturdy by putting corner pieces in and I can make up some bits myself if required. Your adjustments are correct except for the below. J5 needs to be extended to R8a and R23a Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted July 16 Share Posted July 16 Thanks Phil, I will be editing the original drawings over the next week. I reckon the addition of corner pieces will be more than enough to fix the rigidity of the wing building jig. Please shout out if you find any further issues with the plan or parts. Martin. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 16 Author Share Posted July 16 Martin, Thanks for your prompt response. Will let you know if I find any other issues. I had wondered why the ribs had notches which weren't being filled, but the drawing showed them like that. I'm going to get the jig done this week and then go back to painting my Andrew Conway BAe Hawk and 2020 Mass Build Sabre. Phil B Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 17 Author Share Posted July 17 Starboard side jig has been glued together today, including the little balsa block to make the jug that bit more sturdy. Will make up some pieces for those that have been missed, these not currently shown in photographs. Martin is currently amending drawings so that he can supply amended parts in future short kits. Also taken measurement from top of Rib1a to aft outboard of Rib19a which is 978mm so that jig can be checked for movement once of the plan and can be moved back to correct alignment if required. 2 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 18 Author Share Posted July 18 (edited) Trial build of the port wing jig has gone ok and I've managed to get the same measurement from top of R1a to the outer aft position of Rib19a of 278mm. Also fully aligned in a straight line J3. Time to glue it together. Attached photos show the size against my usual build board.

Phil Beard Posted July 19 Author Share Posted July 19 Finished putting the wing jig together including the modifications and also some stiffeners at the joints. Distance measured between top of Rib1a to bottom outer of Rib19a has measured the same on both sides a 978mm. Initial photo of the completed jig, second photo showing the 1/6th scale jig against that of the original mass build jig and finally a photo of the original mass build wing laid onto the 1/6th scale jig. These give you an idea of the size difference between the two difference scale Sabre's. 4 Quote Link to comment Share on other sites More sharing options...
Murat Kece 1 Posted July 19 Share Posted July 19 that will be a big beast☺️ Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted July 19 Share Posted July 19 I'm guessing around 78" ? Am I correct ? 1 Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted July 19 Share Posted July 19 Correct! Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 19 Author Share Posted July 19 Richard as Martin has pointed out it will have a wingspan of 78 inch. Martin should know as he created the drawings and short kit for myself. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 27 Author Share Posted July 27 Not much done on the Sabre this week which was planned as other models are being finished in paint. Decided to start building the fuselage which isn't my norm. Anyway from the plans it states to build the fuselage in two halves, so I've started on the port side. From the photos you can see I've built both port and starboard upper and lower keel beams and have started from the aft frames working forward glueing the frames to the upper and lower keel beams. Since this model is large I'll have to move the plan on the building board so as to continue glueing the frames going forward. Only slight difference to the plan at the top and bottom and at F14 i've included some triangular balsa stiffening to the joint. 3 Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted July 28 Share Posted July 28 It's look good, Phil. I wish my workbench was as clean and tidy as your one! 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 29 Author Share Posted July 29 All frames have now been glued into place and the three 1/4 inch square balsa stringers have been added also. One thing I would do differently is to add the ply doubler onto the front of F4 and drill through the 8mm hole prior to glueing F4 and doubler into place. 5 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 30 Author Share Posted July 30 With the fuselage frames glued to the upper and lower longerons and the stringers fitted it's time to start planking the outer skin from 3.2mm soft balsa which has been ripped into 18mm width strips and spliced into strips long enough to cover the fuselage from the front to aft. Well that's the update for today and lots of planking to get on with. 3 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted July 31 Author Share Posted July 31 No major change from yesterday other than a couple of more planks have been added. 3 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted August 1 Author Share Posted August 1 Still no major change from yesterday other than a couple of more planks have been added. Have to say it's quite therapeutic doing the planking. Most likely will not be saying this by mid next week when hopefully I'll have done the starboard side also. 3 Quote Link to comment Share on other sites More sharing options...
