Chris Barlow Posted January 26, 2016 Share Posted January 26, 2016 Looks good Lucas. I too like built up structures and ladder frame fuselages, Boddington style! Maybe we're just old fashioned? Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted January 27, 2016 Author Share Posted January 27, 2016 Just to show there is more than one way to skin a cat: To fit tyvek hinges to surfaces I mark the middle of the spar with the nifty little tool (I do not remember where I ordered it) that makes an impression in the wood. A fresh #1 blade and some patience does the rest. I use one hinge marked half way to check that the cut it wide and deep enough. And indeed, do not bevel until the hinge slots are done.

AndyD Posted January 27, 2016 Share Posted January 27, 2016 i still do mine by hand,mark a centre line and use a blade,if the hinges are to thick i then mark the depth on a hacksaw blade and push that in and out. Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 28, 2016 Author Share Posted January 28, 2016 a tip to prevent hangar rash on your new build parts: The white stuff is 3 mm foam that is used under parquet. I have half a roll left after the last room was finished which will last for a long time. Can be found in DIY stores (that sell parquet).

McG 6969 Posted January 28, 2016 Share Posted January 28, 2016 Hi Lucas, It seems that you just discovered the 'rolled' version of Depron's grand'dad. Under-parquet insulation is what Depron originally was created for. The idea remains a good tip anyhow.

Lucas Hofman Posted January 29, 2016 Author Share Posted January 29, 2016 Tail surfaces nearly ready for covering (elevator joiner still needs to be glued in place). Nice and smooth after rounding off and sanding: To be able to have the battery behind the firewall and still have the CG right I need to save 20 grams in the tail. The tail surfaces weight 39 grams (without joiner, covering and horns). Anyone who has weighted normal solid plate surfaces? All formers are glued in place. Next will be battery mounting plate, the hatch and the turtledeck. I did receive som 1/8 square balsa for the turtledeck but find that very flimsy. Two weeks silence from today: business trip to the US. Looking forward to start on the wing after returning. Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 9, 2016 Author Share Posted February 9, 2016 Back again, a little earlier than expected. Continue with the battery plate (2mm light ply): And mounting a slightly higher F5, so that is fits between the sides. Tilted backwards, to make the hatch easier to fit: And fitting the lists of the turtle deck. 3x3mm balsa is too flimsy, so it has to be pine anyway. Thanks to Martin for the picture with the elastic bands: And this is the time I found out that I have used the wrong thickness for the fuselage sides . !!! It is 1/8 instead of 3/32. Not a big deal, but irritating since I want to have everything as light as possible. And now I am missing stock for the wing leading edges. A lesson to be learned here: when all wood arrives mark every bit for what it is intended for. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 9, 2016 Share Posted February 9, 2016 Looking good. Irritataing about the 1/8" but perhaps 2 laminations of 3/32 and one of 1/16" will work as well. Orsomething like that, not realy critical. Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 10, 2016 Author Share Posted February 10, 2016 Second half of the stringers last night and started on the battery hatch: I started with gluing 6x3mm lists to the sides. Glued the half-frames F1A, F2A, F3 and F5A on top of those (rebated), together with the cockpit floor. Before F1A and after F5A a 0.6mm spacer (and tape) to create a little gap that should prevent glueing these half-frames to their counterparts . Next is glueing the turtledeck and then comes the moment of thruth: cutting through the 6x3 lists to separate hatch from fuse. Fingers crossed!

Lucas Hofman Posted February 12, 2016 Author Share Posted February 12, 2016 Hatching the Hatch! I first made a template from thin carton to get the angle at the back right and to make the halves with an approximate cutout for the cockpit already in place. The ligthtest 5/32 balsa I had was still quite stiff so I soaked the halves in water and pre-bend them on a piece of pipe: It surprised me how pliable the balsa became when steamed with a hot iron. After drying they could be glued to the sides: THis I left to dry for 24 hours. Thereafter i wetted them again (on the outside) and carefully -again wiith a hot iron- conformed them to the shape of the formers. Some carefull cutting on the centerline and they are ready to be glued to the central stringer: Tomorrow we willl see if the hatch comes loose without breaking...

Lucas Hofman Posted February 16, 2016 Author Share Posted February 16, 2016 The hatch has not been separated from the fuselage yet: Since the fuselage sides are to thick they need a thorough go-over with 80 grid sandpaper. Starting with that revealed that the turtledeck stringer stringers do not permit much handling before slipping from the formers. So the inserts had to be mounted first: Tedious, all those small pieces!. It has to be said that progress this weekend could have been better if I not had been flying, but who can resist a day like this on a frozen lake: OK, back to the bench tonight. Sanding is still hampered, this time by the sides bulging inwards between the formers. Then I had better mount the bottom planking first: Now all should be ready for a dusty session tomorrow, with -hopefully- a separated cowl at the end!

Chris Barlow Posted February 16, 2016 Share Posted February 16, 2016 Lovely photo of the lake Lucas. I can imagine some smooth landings in that. And an impressive collection of screwdrivers too! Way more impressive than glue pots. Wear a dust mask when sanding the balsa, it's pretty nasty stuff and if possible do it outside. The dust gets everywhere!

McG 6969 Posted February 17, 2016 Share Posted February 17, 2016 Hi Lucas, Very tidy build there. You are really thinking way in advance how to approach & plan your construction. Excellent job. I'm really curious about the final weight. Indeed very impressive collection of screwdrivers... By the way, do I see some reddish sign in Dutch - "heb je even geluk" - between them???

Craig Thomas Posted February 17, 2016 Share Posted February 17, 2016 Just google translated what Chris thinks the sign says. " "did you just luck"?? Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 17, 2016 Author Share Posted February 17, 2016 Posted by Peter Miller on 17/02/2016 08:16:25: OOH! That looks cold!!! Not really, around 0 degrees. With no wind and a lot of sun that is pleasant to be outside. Better then 10 degrees, moist and windy. With -10 to -15 one gets icing, frozen servo's and slow fingers though. But nothing beats frozen water as a runway - like flying from and inmense biliard! Quote Link to comment Share on other sites More sharing options...

McG 6969 Posted February 17, 2016 Share Posted February 17, 2016 Strange translator you have there, Craig. "Geluk" means 'luck' or 'happiness' in Dutch. In this meaning as part of a more complete sentence, it could be translated by "... then you must be lucky". Sorry to jump in, Lucas.
