Phil Beard Posted November 29, 2022 Author Share Posted November 29, 2022 Aft fuselage and exhaust area continues to be constructed with the addition of the exhaust area which is glued onto the back of the aft fuselage but currently not with the aft fuselage top in place as access will be required to complete the elevator mechanism. Frame F9 is now added at the rear of the exhaust area as can be seen in the photo. 3D printed pilots have arrived today which were developed specifically for the Andy Conway Hawk by Andy Meade who creates various different sizes of pilots, ejection seats and other associated parts using 3D printing. He can be found on this website looking for his profile if you'd like to get some from him. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted November 30, 2022 Author Share Posted November 30, 2022 Working on fuselage to start putting in the aft sides and bottom and it dawned upon me that F6 had been glued in the wrong place as the 45 degree part should have met the bottom area. All fixed and now in the correct position. Also decided to lengthen the 10swg rod that will work as the mechanism for the elevator so that it goes in full into each side. Now 126mm long as can be seen in the photo. Mechanism being built up at the moment and working out control run and way to hold elevator servo in place as the plan shows it in free air. Once everything is sorted I'll fully tighten up the grub screws once certain everything is ok and then epoxy all in place as I never want these to move again. Aft fuselage is double skinned between F8 and F9 and the photo shows me getting it to the correct shape.. THis will be glued in place once the mechanism is finally completed as no access can be had after that. Things feel to be progressing slower but I think I've hit the fiddly bit of the build.

Phil Beard Posted December 1, 2022 Author Share Posted December 1, 2022 Started installing the elevator control linkages and some parts to hold the servo in place and also keep the linkage in place as can be seen in the photos. Decided to change the bowden cable to an alternative type at the end as I didn't have any M3 clevis to use. Doesn't seem much but lots of mucking around to get to this stage. Final length onto servo will be done tomorrow and then I can start closing up the aft end of the fuselage and it'll look like more progress is being made.

Phil Beard Posted December 2, 2022 Author Share Posted December 2, 2022 Got the elevator mechanism working ok to the extent I can start building up the aft fuselage and exhaust area. Took a video of the elevator working and it moves +/- 15mm as opposed to the +/-12.5mm specified on the plan. Will leave it at this but I've been warned not to use too much elevator as you need to keep the model moving or else it will stall.

Phil Beard Posted December 3, 2022 Author Share Posted December 3, 2022 Decided to add a collet at either side of the elevator mechanism within the fuselage to stop the lever being pushed either way which would increase friction to move the elevator. Note you'll have to add recesses either side on the top skin to allow the collets to sit in. Aft fuselage bottom inner skin fitted and the edges angles to 45 degrees. Apologies about previous videos but unfortunately my camera creates larger files that the site can handle. I think the build will look as though it's starting to progress quicker shortly with all the other skins being added. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 4, 2022 Author Share Posted December 4, 2022 Aft fuselage bottom and side skins now fitted as can be seen in the photos. Don't forget to mark some holes for where you need to place the ventral fin later. Last 2 photos showing it starting to resemble a BAe Hawk. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 4, 2022 Author Share Posted December 4, 2022 NEED HELP Starting to think about painting the pilots whilst other things dry and so on. Has anyone got some good pilot photos they can share with me for these 2 pilots as shown in the below photo. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 5, 2022 Author Share Posted December 5, 2022 I thought I'd have a change today and cutout the canopy to fit onto the fuselage. As can be seen from the photograph this canopy is quite well marked to show where the cut line is required except for the front it's a bit harder. Well the first thing to do is to cover the canopy in masking tape and marking the cut line at the edge as can be seen in the photo. The masking tape stops and marks or scuffs happening to the canopy and is well worth the time doing this step. The essential tools for cutting the canopy is scissors as can be seen in the photo. Don't try your scalpel as it doesn't anywhere near as good as using scissors as I've tried in the past and the scissors are quicker and give a superior cutline. Final photo shows the canopy placed onto the fuselage which still needs a bit of shaping in this area but the fit looks good for the initial fit.

Phil Beard Posted December 6, 2022 Author Share Posted December 6, 2022 Aft Port Fuselage and exhaust area sanded to shape tonight will do the starboard side tomorrow. Took a bit of visualising what the final shape should be. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 7, 2022 Author Share Posted December 7, 2022 Aft Fuselage and exhaust area finished and the ventral fins underneath the fuselage have been fitted but will only be glued in place once the fuselage has been glass cloth covered. Final bit of shaping in this area to be undertaken just behind the fin. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 8, 2022 Author Share Posted December 8, 2022 Starting to install and shape the engine air intakes and the fairings. For the engine air intakes you'll have to make a notch in the bottom as show in the first photo. This will allow it then to mate up with the area with the round hole in. Not sure if this was my mistake or not in the order these parts were installed. Put the engine air intake against the fairing and mark round so that you can see the area required to be removed and shape required. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 10, 2022 Author Share Posted December 10, 2022 Engine inlet cowls along fuselage starting to take shape. Taking more time than I expected. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 11, 2022 Author Share Posted December 11, 2022 Engine inlet cowls have been attached using double sided tape so that these can be sanded into shape in conjunction with the fuselage. Note the gap will be filled once the engine inlet cowl is permanently attached after glass clothing the fuselage in the gap between the inlet and fuselage as this are wouldn't be accessible otherwise. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 12, 2022 Author Share Posted December 12, 2022 My BAE Hawk T1 from the Andy Conway plan is starting to come together and look like a BAe Hawk. Still loads to do, but I thought I'd post a photo. F86 - Sabre is also coming along nicely at the same time and hopefully both will be glass clothed and sprayed at the same time. 5 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 20, 2022 Author Share Posted December 20, 2022 Well I'm back with my build blog after being away on business working on full size aircraft. You'll see that I've joined the wing halves tonight, making sure that I've got 12.5mm blocks under each wingtip and also needed a bit of shimming in the middle for which I've used some 1/32nd thickness balsa to fill the gap. Wing is going to be glass clothed later and that will provide further strength at this critical area. Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted December 23, 2022 Share Posted December 23, 2022 Hiya Phil - some great progress and you've got the shape looking really good!! Just one question for clarity on your wing re: the glass cloth - do you mean you will be joining the 2 wing halves with a 1" glass bandage along the centreline? As I think this is essential without the use of a ply wing joiner here - Just want to clarify you are not reliant upon the surface finishing glass cloth as I think it could be read that way... 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted December 31, 2022 Author Share Posted December 31, 2022 Phil I was just going to use the surface finishing glass cloth as you'd read. I'll take your experience and use some 1 inch glass cloth for the wing joint as this wont be seen externally as the underside of the central wing needs the balsa to form the shape in that area which will cover the 1 inch glass cloth and will finally be covered with the surface finishing glass cloth. Thanks for your input and advice. Build is back in progress now I'm back home after visiting family over the Christmas period. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted January 1, 2023 Author Share Posted January 1, 2023 Wing leading edge shaped at the area where it joins the fuselage as can be seen in the first 2 photos with the third photo showing the 3mm Birch plywood at the front of the wing which meets the fuselage. This will be sanded to shape once the epoxy has dried and filler will be used to blend the shape. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted January 2, 2023 Author Share Posted January 2, 2023 (edited) Birch plywood Wing to fuselage interface sanded into shape and 1.5 inch wing bandage epoxy bonded onto lower wing skin. Don't worry about the rough looking bandage as this will soon be hidden by the fuselage saddle which go over the top of it. Bandage also put on the top surface also and this will not be seen externally.

Phil Beard Posted January 3, 2023 Author Share Posted January 3, 2023 Wing interface to fuselage' large gaps can be seen on both sides which after checking has been put down to drawing error. This can be fixed by taking a piece of balsa the same thickness as the ribs and cutting the top curved part of Rib 2 into and temporarily sticking to the fuselage side and then back cutting from the fuselage inside so that you can get a matched curve from the fuselage and then glue onto the bottom. Process then done in the same manner on the other side. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted January 4, 2023 Author Share Posted January 4, 2023 As can be seen from the photos the wing to fuselage gaps have now been sorted. Onto to building the fuselage saddle so that the wing build can be finalised. 2 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted January 5, 2023 Author Share Posted January 5, 2023 Decided to start glass clothing parts of the model and have started with the elevators. As can be seen from the photographs I'm using 25g glass cloth and epoxy skinning resins from Fighter Aces as I'm going to be spray painting the model later as XX285 as can be seen in the final photograph. 1 Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted January 6, 2023 Author Share Posted January 6, 2023 Reinforcing for wing bolt cutout and fixed in position as shown in plan. Fuselage saddle being attached to lower skin after fitting wing bolt reinforcing. Plan does not detail the fuselage saddle unfortunately.
