Gary Manuel Posted April 6, 2014 Author Share Posted April 6, 2014 Don't think it's all straight edges. The front of the fuselage has a slight compound curve, and needs to be gradually taped into place before leaving for the to dry. Quote Link to comment Share on other sites More sharing options...

Gary Manuel Posted April 6, 2014 Author Share Posted April 6, 2014 Underside skinned. Note that the rear 150mm or so has a triangle of two pieces of laminated 3mm lite ply for screwig the rear tail wheel bracket to later. Quote Link to comment Share on other sites More sharing options...
Roy Mundy Posted April 7, 2014 Share Posted April 7, 2014 Looking good so far Gary, I bought the DVD about 2 years ago and one day I will buy the kit and have a go. I will be watching with interest. Nice work mate. Regards Roy Quote Link to comment Share on other sites More sharing options...

Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Posted by iqon on 07/04/2014 17:46:41: this looks like a good colour scheme I know Dusty very well and was already considering this colour scheme. You are obviously a connoisseur of fine models and films. What did you think of the film? Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted April 7, 2014 Share Posted April 7, 2014 Posted by Gary Manuel on 06/04/2014 22:00:13: Posted by Kevin Fairgrieve on 06/04/2014 17:25:58: Glad to see you did not have the same issue`s that I had. My Farmhand build. It is finished ready for covering. Kev Edited By Kevin Fairgrieve on 06/04/2014 17:35:14 Hi Kevin, I read your blog with interest before I started mine. Gave me a few tips for what to look out for. I assume the issues you are talking about are the inaccurate laser cut parts. No mine were all pretty good. I felt for you when you got to the bit where the servo holes were in the wrong ribs The positive side of making the mistake and publishing it is that it helps others avoid similar problems. I made sure that I cut some small squares in the lower surface before I skinned the top (see later in my build log). You can take some credit for that Hi Gary. Yes mainly the issue`s with the poor fit of the CNC cut parts. Pleased yours were OK, I think maybe Traplet took a look at the kits after I and a few others commented. The servo cut outs in the wrong position is an embarrassment but not a big issue. Like you I did also cut a small hole in the skin, just in the wrong place, as I had already put the servo mount between the wrong ribs. Now that my two builds for Greenacres are complete, I feel the need to cover the Farmhand. Kev Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Time to make a start on the wings. 4 off 48" x 10" sheeting needed for the wings. I made 4 of these (upper and lower x 2) by cutting a 48" x 4" lengthwise to make 2 off 48"x 2", then taping it between 2 off 48" x 4" sheets. All sheeting 3/32" and laid flat on an old double glazed unit that suddenly and expensively became a single glazed unit accidentally whilst I was building my log cabin Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Sheets turned over and supported in the hinged open position to allow glue to be run in. Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Like this: My first attempt at this method used thin cyano which ran out half way down the run. Almost ended in disaster. Following ones I did with aliphatic resin like this. After running the glue in, remove the supports so that it lays flat. Wipe of excess immediately, tape over the joint and leave overnight. I have subsequently switched to using cyano now I have practiced this method as it avoids the taping and overnight wait. I have learnt to make sure I have enough cyano in the bottle before I start though. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted April 7, 2014 Share Posted April 7, 2014 You got central heating in the log cabin Gary ? That's a fair old piece of wing sheet your doing, clever use of the tape, like it Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 9 x 6 mm spruce spar cyano'd along one edge of the sheeting. Ribs used to line up the position of the main 9 x 9mm spruce spar before cyano'ing into position. Ribs, servo trays and webs glued in position with aliphatic resin, taking care to get all the ribs in the right place as shown on the supplied diagram (Kevin ). There are 4 different types of rib: R1 = root - with a long slot in the leading edge for the Wing Locator Tab which is added after the wing is fully sheeted. R2 = special second from the root with an extra cutout for a short spar (To allow toffee bomb slot to be cut out if required later). R3 = basic rib. R4 = with slots for the servo trays.

Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 John, 2kW convector heater but I don't use it often - mainly used for lengthening epoxy setting time rather than keeping me warm. Tape hinge method for sheet joining works well. 100% success rate so far. Key is having a flat surface and everything to hand (cyano) before you start.

Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Everything should be straigh as long as you start with a straight sheet at the trailing edge spar Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Engine arrived while this was going on. Nice shiny DLE55RA. Should have enough grunt I think Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 To control the motor, I'll need a couple of servos to be mounted well inside the fuselage (DLE say 12 inches away from the engine) One for the throttle and one for the choke, which I may decide to replace by a simple manual arrangement. After much consideration, I found a suitable place (spoilt for choice really) and made this servo tray from a bit of scrap lite-ply. Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Servos in place (small pieces of scrap lite ply cyno'd on rear to screw into). Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 And glue in place using suitable bracing. Note that the chute here is for placing sweets in when using as a toffee bomber. I won't be doing this. The 750ml tank is planned to go approximately here, which is approximately at the CofG position. Note ply shelf added to support the tank bringing the mouth of the toffee chute. Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted April 7, 2014 Author Share Posted April 7, 2014 Trial fitting of the engine, using the DLE supplied standoffs. Note servos are (deliberately) quite remote from the engine / planned ignition unit position. Quote Link to comment Share on other sites More sharing options...
