John's Ballerina Build


Recommended Posts

Cheers lads

Not much to show you yet, I've fettled all the ribs I cut ready to start building a wing, it will be built in a slightly different order to Peters method but we'll end up with the same wing, only alteration is a fuzz mounted u/c, and i'll build wing as one and cut the ailerons out.

Made a dihedral template, as you can see it's upside down, best remember when I fit the rib wink

How do you get on with your slec stripper John? Im not so sure on it? It's a bit of a pain to adjust the cut width. Remove all 3 must to add/remove spacers. I've only used mine a couple of time at the moment and maybe need more time to get used to it. But at the moment I would say only 3 pot of every 5 cuts and accurate at the moment. I keep catching my fingers on the white plastic nuts as I make a cut.

DOH ..................

The Kavan stripper is very handy for cutting the odd strip or short length but for full lengths and lots of cuts I prefer the Slec one.

I have recently treated myself to a Slec building jig so will be mounting the Ali channel for the balsa stripper to one edge of it. The grid of the jig is stuck to an over sized piece of 3/4 ply leaving loads of room for the stripper and saving space in the workshop too!

These are brilliant for strip wood, especially if a friend has one and cuts is for you laugh

I'm thinking of a Ballerina for my next build, how do we think it would go on an old Vega 50 twin which would just fly a Flair Magnatilla.

My OS FS40 Surpass turns an 11X6 prop at around 10,000 rpm. If your Vega twin does roughly the same it will be fine.

Interestingly you are building the wing the way I would. With it "packed up" in key places, then add the le sheeting after removing from the board.

I notice that Peter suggests a slightly different approach - he puts the le sheeting down first, then adds the spars etc and finally the ribs. If I understand correctly he then glues the sheeting up onto the ribs while the assembly is still on the board. (Please feel free to correct me if I have misunderstood that Peter!). So the sheeting is effectively his packing during assembly.

Pondering now, whether to stick with what I know - ie the way you have done it - or branch out and try something new!
