Ninja

Off to the wings and a task I was dreading, described in the manual as "truing the edges" of all balsa sheeting parts. I got a nice hardened steel ruler from Homebase and gripped to the table on one end, held the other to shave all irregularities. I did something wrong or I simply have too idealistic views of the extent to which natural materials can be finished. But when gluing the sheeting together, I found there was a bit of warping. When the five pieces were glued along, the resulting skin was not flat, but raised above the worktop one or two mm here and there.

Gluing was also interesting. I used thin CA, with waxed paper underneath, but still had to pull stuck paper stretches a few times. No damage though.

Below are my finished wing skins, not exactly flat as you can see.

I followed this video to glue the wings (starting from 3:00):

PU glue (I found Gorilla glue in Homebase), spread thin with a plastic card, bit of moisture in the air and to the press for 24 hours. Average humidity while gluing and curing was 65%.

With the exception of a couple of tiny spots where I spilled glue on the outside of the skin and had to sand a bit of mould foam, things went ok. Trimming the skins down to the core was scary (done by hand with blade, the planes I have seen look too heavy for the job) but it's done. Sanding was done handling the wing over worktop covered with 200 grit paper. Tricky - I wonder if there is a better way.



Next, gluing leading and trailing edges, and wingtips. PU or epoxy? If you feel strongly about one of those, please shout... soon

Try a search for a Davids plane, small and handheld uses a double edged razor blade

Thanks. This one perhaps? http://www.skykingrcproducts.com/accessories/david/david_razor_plane.html

Been watching that video. I have a foam core wing to make and I found it very interesting. (That guys’ accent makes me die! :lol: )
But it’s a very informative video, all-be-it a little ‘long winded’.
Well done for finding it Antonio :clap:

Yes, the pace is a bit slow. Having done my wings I think perhaps he was using too much glue. That thing expands and will find its way out through every possible opening! Gluing the leading and trailing edges I used PU too, and where it found its way out, shaping and sanding was not easy!

Here's my LE done:

Yea, nice profile, looking very good. :clap:

I don’t mind the plane’ing of parts to shape, (can’t think how to spell the correct word :evil: …..I want the verb for using a wood plane…Oh never mind!! :roll: )  it’s the sanding I don’t like.
I have to wear a mask to stop the dust getting down my throat, but then I find that my breath  exits from the top of the mask and tends to fog up my spectacles. :x  Coupled with that, everywhere in my small workshop gets covered with the dust as well.
When possible I do as much sanding as is practical in the garage , or in summer, out in the garden but that’s a bit of a ‘pain’ traipsing everything outside.

God, I sound like a grumpy old man don’t I! :roll:

I think we should call it the GOLF club. (Grumpy Old Lazy Flyers club!) :lol:

BTW anyone heard anything of Richard lately? I haven’t seen him since the September Glide In

[andrew wallace]

keith, Richards alive and well   i haven't seen him since the last area meeting in November but i would get a text nearly everyday, he's in the man cave  lol

[Happy Days]

Thanks Andy, I’ll send him an application to the GOLF club as well! :lol:

I think I’ve rather hijacked Antonio’s topic, :oops:  sorry Antonio……..how is the Ninja build coming?
 
More pictures please!

A bit late, but well done, looking very good so far  :clap:
I had a Ninja a long time ago, and along with the Ridge Racer was one of my favorite glider at the time

Don't worry Keith, the only things that are hijacking this thread are my work and evening studies.

All I did during the week was glue the wingtip (a square block, just like your Riser's noseblock) and more carving! The instructions say rough shape only for now, so that's where I left them.
