Biggles' Elder Brother - Moderator Posted February 3, 2014 Share Posted February 3, 2014 Working from the plan I'll think you'll be OK - I think its the CNC cut kit (that us lazy types use!) that is at fault. It is definitely a bit of a head scratching moment though when you offer the tail up to the canoe and realise they are not the same size! Looking very nice Kev.

Kevin Fairgrieve Posted February 3, 2014 Author Share Posted February 3, 2014 Posted by kc on 03/02/2014 12:21:05: Did you use a template to cut each rib out or sand them all together in a pack? First to kc`s question, because it will be quicker to answer than the others!!! I cut each rib individually using a ply template. I could have used the sandwich method, but find the challenge of getting accurate ribs very rewarding. Kev Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted February 3, 2014 Author Share Posted February 3, 2014 Vecchio and BEB. Well!!! As you can see I built the rear frame directly over the plan (free pull out one) and as you can see it looks good, the "longerons" going all the way to the rear of the wing seat. Took it off the bench today after work and offered it up to the "tub". Oh dear. Decided to check a few things. Placed the rear frame on the plan side view aligning the first cross member with its relevant location. All the other cross members also line up. As you can see it comes up short. Side view measurement from tail end to front of "longeron". Same measurement from tail end to top plan view. It is coming up just shy of a 1/4 to short!!! When I offer up the rear deck to the "tub" I get the impression that the first cross member is to wide or the fuselage rear is to small.!! So measure across the plan. Measure across the "tub". Just had a quick measure of F4 against the plan and all is correct. What I think I will do is remove the first cross member from the rear section and insert a smaller one. Looks like no two "Dawn Flyers" are going to be the same. Kev Edited By Kevin Fairgrieve on 03/02/2014 17:35:36 Quote Link to comment Share on other sites More sharing options...
Vecchio Austriaco Posted February 3, 2014 Share Posted February 3, 2014 So it is a plan problem after all - and we shouldn't complain about the laser cutter programming.... I am sure you will find a solution, I personnally cut a bit of the first cross member of and the job is done. VA Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted February 3, 2014 Author Share Posted February 3, 2014 I think you are correct VA. I think F4 is the wrong size on the plan. I laid the "tub" over the plan pinned the paddle in place, lined it all up along the plan and bingo. The paddle fits perfectly, well it will once sanded to shape, but as you can see the "tub" tapers in towards the rear which indicates to me that the top of F4 is not wide enough!!!

Kevin Fairgrieve Posted February 6, 2014 Author Share Posted February 6, 2014 So on with the wings. Not a lot to show for them, as the wing build is just like any other. Fear not the clamps are only just nipping the wood. No damage will occour, nor any bending of the leading edge. One down, the other on the board.

Vecchio Austriaco Posted February 6, 2014 Share Posted February 6, 2014 comes up very nice! I like wing building, at the beginning all is a fragile structure and after sheething and covering a stable wing is on the table. VA Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted February 6, 2014 Share Posted February 6, 2014 Funny isn't it - I prefer fuselage building to wing building. BEB Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted February 6, 2014 Author Share Posted February 6, 2014 Wings, fuselage, I generally enjoy all aspects of a build. If I had e preference though, fuselage would win. Anyway, back to the build. As you can see I chop and change a bit when building. I like to be able to go back to a piece whilst another is drying. Top front sheet finished. And the undercarriage plates being epoxy`d in place. Again the clamps are on a piece of scrap balsa to prevent damage to the wing seat.

Kevin Fairgrieve Posted February 10, 2014 Author Share Posted February 10, 2014 Work and the fact that the car just had an MOT and service which cost me an arm and a leg, I have not done a great deal recently. I have only managed to do (very badly) the rear lattice work. As you can tell it is a picture from today. The latest RCM&E is lurking. Kev PS. No the glue stick was not used to do it with.

So tis the plan not just gremlins in the CNC pack then. I am now hooked on this builds as I am with BEB's, Kevin so keep it up please.

WOETC (Rob) Posted February 11, 2014 Share Posted February 11, 2014 I've built 3 DFs now (2x original size and 1 scaled up to 1.5 times) and glueing the upper longerons to the tub first is exactly what I did for each of them. Maybe its my "downunder" brain but it didnt occur to me to build them as separate units and then marry them up. Its the way to go as I didnt have any issues. Once the glue had dried, I glued ply doublers across the longeron to tub joint (on the inside) and then turned the assembly upside down so I could draw the longerons together over the plan in the normal way. BTW, I've put a cheap HK sound unit in the big one and its pretty cool. Cheers, Rob Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted February 14, 2014 Author Share Posted February 14, 2014 Little progress to report of late. Just the rear decking fitted ant trim`d to shape. I was pleasantly surprised at the amount of strength that this has added to the rear. I thought I had more wood in stock than I actually had, so I feel another visit to SLEC coming up. Not this weekend but maybe next. Kev Quote Link to comment Share on other sites More sharing options...
John Manning Posted February 14, 2014 Share Posted February 14, 2014 Kev, Thanks for your build blog. A few pointers that I must note as I move on with my build. JohnM Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted February 25, 2014 Author Share Posted February 25, 2014 Work has been a little hectic over the last week or two, so very little progress made. I have fitted the tail skid, lots of epoxy and a ply strengthening strip on the lower 1/4 square. However the postie did deliver these this morning.

John Manning Posted February 26, 2014 Share Posted February 26, 2014 Kev, where did you get your wheels from? I may as well order them then I can try the undercart while I wait for the cnc and wood pack to arrive. I could try and get my pilot 1/12th scale to move his head and arm. Then Alex W. will see the pilot wave! John M Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted February 26, 2014 Share Posted February 26, 2014 I took some shots of Dennis Richardson's Dawn Flyer at Ashbourne, he had used some really nice wheels. He told me where he got them, but I can't remember where he said. I think they were around the £30 mark If anybody is interested I can mail him?

Kevin Fairgrieve Posted March 10, 2014 Author Share Posted March 10, 2014 No I have not forgot about this. Progress has been slow but, but a lot achieved. Now that`s a strange way to put it. Work on the cockpit area had me scratching my head. Lots of curves and bends to consider. I got to work with the water spray bottle, and this is the result for the front half. Not really as neat as it looks! I made another $3 and placed it in front of the current one. Somewhere for the back half sheet to fix to. Again out with the spray and tape it in place till it dry`s. Once that was done, I gave it a light sanding to feather it all in and then cut out the cockpit. There is a tiny bit of wood missing right at the front, but that will disappear when the cockpit edging is in place. Once that was done it was time for a motivation shot. So that is basically the woodwork finished. I will take the whole lot outside tomorrow, and give it a good sand in preparation for staining and covering.

Kevin Fairgrieve Posted March 11, 2014 Author Share Posted March 11, 2014 All rubbed down. So on with the first coat of stain. Looks OK. Oh dear. Looks like I have the same issue as BEB. But I have decided that I am going to leave it. And I was so careful not to get any glue where it was not needed. I missed a few bits in the cockpit area, but I may as yet paint that black.
