--- Quote from: "Fred" ---Alan, what were you thinking this glider was ? Honest ! :P

I thought it was a glider made from glassfiber shit :P :P . But seriously looking at the shape of the parts and the year it was made, it could only have been the Grunau Baby. But I would not have known if it was'nt for Marten Simons books.
Fred:
Did not have enough free time yesterday to commit to gluing something (was going to start the elevator...), so instead, I put the fuselage together quickly to have a look (curious me ??)
Hop, no glue :D
All looking good so far.
And I've put everything back in the box, I'll go back to the fuselage later, after I've made the second wing (that was more of an apetiser of what is coming next :D )

Great work Fred. :clap:
Fred:
Thanks Anthony ! :D
Fred:
Still moving ! :D
Here is today's work, with the elevator.
All the parts :
Mostly 10mm Balsa and 2mm plywood.
As usual, everything is put on the plan. The elevator ribs are slided into each slots on the stab TE/LE, and glued... I have to admit that I used thin CA everywhere here... :oops:
Really easy...
A few adjustments are needed there and there for the ends of the ribs to fit tight...
And after... Well, not that long, you have a fix elevator ! :D
Now to the moving part !
Same as the fixed one, except this is not build on the plan, but "in the air". Same principle...
2 halves. They are then joined with a piece of 3mm plywood glued with epoxy.
Et voila !
A bit of sanding will then be required to smooth everything.
Happy, but the idea at the design process was to have a stab ready to be covered once glued and sanded... But because I want a all plywood finish, I will have to add 0.4mm on the elevator LE to apply the vanish on.
Can definitively be left as is if you go for a covered/painted finish.
So far, I roughly spend 5 hours on the project :D
Tomorrow, back to the wings !
