The MBK Dowel Delta


How To Make A Delta Kite
Keel

50 pound strength Dacron line is ideal for these Dowel Series kites.

It's possible to make a Delta kite without a keel, but this one flies very well as designed. Besides, if you make the keel from plastic in a contrasting color, black for example, it can really add to the kite's looks in the air.



The Dowel Delta kite keel - 1.
  • Mark out the keel shape on some spare plastic, as per the dimensions on the template.
  • Cut out the keel and tape down 3 lengths of flying line onto one side. Each line goes from the towing point to one of the 3 attachment points. Use sticky tape, not electrical tape. Allow the lines to extend about 0.12DL (15cm, 6") past the plastic at each end, as in the photo.


The Dowel Delta kite keel - 21.
  • Now flip the plastic over and tape down another 3 lengths of flying line, directly over the first 3.
  • Reinforce the keel corners by sticking down and wrapping extra bits of tape where the pieces of line come out, making sure the plastic remains flat.
  • Where 2 pieces of line come together, tie them both into a Multi-Strand Simple Knot close to the plastic. These 3 knots will sit against the vertical spar. See the photo, which shows the middle attachment point knot.


The Dowel Delta kite keel - 31.
  • The 6 pieces of line come together at the Towing Point. Tie the 6 strands into a Multi-Strand Simple Knot close to the plastic, then tie another Multi-Strand Simple Knot further out, as in the photo. I've also trimmed the free ends to neaten it up.


The Dowel Delta kite keel - complete.

 Here's the completed keel.



The Dowel Delta kite keel - taping to sail.
  • Using a pen or pencil, poke a hole in the plastic sail exactly 0.36DL (43.2cm, 17 1/4") from the nose of the kite. Right over the vertical spar.
  • Thread the middle keel lines through the hole and tie off tightly. A Granny Knot will do.
  • Poke holes in the plastic for the upper and lower keel lines too, using the keel itself to find the exact spot along the vertical spar. Thread the lines through and tie off tightly, as you did for the middle hole.
  • With the keel flat against the plastic sail, add sticky tape between the knots, attaching the keel to the sail plastic. See the photo, where I have added a yellow rectangle to show where the tape is.
  • Flip the keel over and do the other side.


The Dowel Delta kite keel - knotted to vertical spar.

In the photo, the whole sail has been flipped over. The keel can be seen through the sail plastic, and also visible are the upper 2 knots tied off against the vertical spar.

At this point, you've pretty much finished making the Dowel Delta! However, there is a short setup procedure to go through before it will fly...



How To Make A Delta Kite
Attaching The Spreader

The Dowel Delta kite - plan view.keel - 1.
  1. Spread out the kite, with the keel touching the ground.
  2. Locate one tip of the spreader over its leading edge spar, wind each end of the shoe-lace around the spreader dowel, twice then tie the shoe-lace firmly with a simple bow.
  3. Similarly, locate the other spreader tip and tie off.

Note: You might be tempted to wind the shoe-lace around both dowels. That is, where the leading edge and the spreader cross. Don't do this, as the knot will loosen much more easily in flight!

    Tetra Takes Off

    It's been a bit of an uphill battle getting a decent flight out of the heavy, crudely put-together 10-cell tetra... Earlier today the breeze was great but misty rain persisted for hours on end. Finall…
