Martyn K Posted February 4, 2016 Share Posted February 4, 2016 That looks like a cheaper alternative to carbon capped balsa sheet Nice one - I'll try that myself Martyn Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 4, 2016 Author Share Posted February 4, 2016 Definitely cheaper, Martyn. I read about a French modeling designer who is updating his older designs from the seventies with more recent techniques & he uses laminates a lot. Specially combining Depron with balsa for example for shear webs & even lightweight ribs. My cross-grain idea came from his tutorials. I'm going to use the Deply for different parts of the Bella as I wrote Peter. Thanks for your comments.

McG 6969 Posted February 4, 2016 Author Share Posted February 4, 2016 Hello again, I forgot to mention that I could have used the ‘Deply’ for my fuselage sides & the battery bottom… Quite a bit (lot?) lighter than the birch ply. Ppfff… another ‘main’ lesson learned… As they say in Colin’s Black Country’s very own dialectics: “Once you go Deply, them is nowt to worreye”… Hakuna matata Chris BRU - BE / CTR Deply4 Control Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 ... certainly not in relation with Colin's Country but there is also a well known Swahili saying that can be translated into: "Once you go Deply, you never go Black again".

Devcon1 Posted February 5, 2016 Share Posted February 5, 2016 I like the lamination idea with those materials, very interesting. I do like seeing this experimentation. Regards John Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 Thanks for commenting, John. You're right, it's a lot of fun to experiment with. In a former life, I use to work quite a bit with composites (cfr my public profile, please) but in full scale and not with Depron of course. We used to often work with 'honeycomb' structures sandwiched between GF or Carbon to get very lightweight but rock solid laminates. In fact, the basic idea is the same as with my 'Deply' here, the Depron & ply just having to replace the real life composites. Of course you can cover the foam with balsa as well. If, for example, you take a piece of Depron whatever thickness - or just a 'free' pizza under tray - & cover it both sides with laminating vinyl film (about 40-45 micron thickness) , you will be amazed by the difference in strength of that laminate. Just try it... Hakuna matata Chris BRU - BE / CTR Pizza Control Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 Hello everybody, I definitely inverted my correct building sequence by gluing the carbon fibre strip to the plybox instead of gluing it to the fuselage side first and then bringing it to the plybox all together. Another lesson learned… Thus it was a bit tricky to align it correctly, but as Danny wrote, at the end all went well. I clamped the fuse to the building board and measured (maybe too much?) the best I could to get a correct side symmetry & motor mount angle. Time will tell after curing… Don’t tell The LotH but some of the clamps are not mine. Hard to notice anyway! Now it looks like “Forrest Clamp”… err… or is that the title of a novel written by Winston Groom? … Hakuna matata Chris BRU - BE / CTR Forrest Control Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 Hi to all, When I received my SLEC order - instantly becoming official sponsor of Royal Mail - I was really surprised by the size of the bottle of Aliphatic glue. As I suspected, when I used it the first time for the fuselage sides, it handled with the same ease as a full gallon jar! So, decision was made to protect my wrists from further injury and to decant it in a small bottle with thin sprout obtained from our SZX friends. What’s the best trick here? How are you guys handling it? Hakuna matata Chris BRU - BE / CTR SZX Control Quote Link to comment Share on other sites More sharing options...

I have a 112 gram bottle and a 500 gram bottle and I decant from the big bottle into the small one when it is empty. I also smear Vaseline round the neck of the small bottle and insde the cap because after some time it builds up with dried glue and becomes difficult to open.

McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 Thanks for your tips, Peter. I already thought the 500ml bottle was quite 'unhandy'. So, glad as a newcomer to be confirmed, at least by you, that I'm not the only one on this forum. And the vaseline trick seems great, even on my small tiny Asian bottle, although even on the cheap side, their cover lip seem to be some 'unsticky' silicone stuff. Very nice quality...

McG 6969 Posted February 5, 2016 Author Share Posted February 5, 2016 Thanks for obviously not noting about ' the colored LotH's clamps', Andy. And yes, Peter's 'vaseline' idea remains one to note on a filed or dedicated post-it collection, like I do, writing everything down on common paper ... or, why not, even maybe creating a dedicated Excel file for it.... but too much for me, though, that Excel file, .

McG 6969 Posted February 6, 2016 Author Share Posted February 6, 2016 Hi again, After curing I could remove the ‘forrest’ and have a first close look at the joints. As I haven’t mounted F5 nor the top part of F6 already, I was able to reverse the fuse and rest it on the CF strips. After clamping, I could measure the side and downtrust with the ‘clinometer app’ on the smartphone. The lateral inclination was perfectly 0°… yappie! The vertical one showed 0,8°. Which should mean -0,8° with the fuselage in ‘normal position’. So I created myself a downtrust of nearly 1°. I think I can live with that, especially that my motor is going to be stud-mounted and any possible adjustment can be made later. “Very pleased with this result”, Your Honour… Well, it also seems that I’m clamped with my birthday present already. Maybe I would have preferred a 60W Laser Cutter or a nice CNC Router, but then there is a lot of them ‘washpins’… hmm… could also have been worse with some toothpicks instead!

McG 6969 Posted February 6, 2016 Author Share Posted February 6, 2016 Thanks for visiting, John. Well, I might have a problem around here, somehow, somewhere... Peter & Chris B already wrote that they were watching but also were waiting till I should show 'something' that they could "recognize" in my build... Now you are - in a very gentle way - writing me that it will "look great with a fuzz stuck to it". Thank you for that. But the fact is that THIS IS my fuselage. The sides only need some fine sanding and a few pieces of Solartex or equivalent. I hope that when I have the hatch in position and the tailplanes added, it will not look like a U-boot anymore... ???

Is the fin/rudder just glued 90 degrees to the tail plane? The back of the fuzz still looks very 2 dimensional. Now I'm baffled! Help!

Yes, it is my very first build of an RC model, no "spoofy tale" here. I'm trying to pay attention to scrape the glue away right away (thanks to Lucas for his advice) after getting the parts together. Easy to do with a popsicle stick cut at 90°. No need to be envious though, the first parts I glued are really 'messy'. .. and it just could be my last build as well, since some Musketeers entered to Ballerina scene... I can feel the roots of a very well organised conspiracy from some 'old balsa bashers' against the Bella!
