| Waiex Main Wing Spar Construction |
My project begins with the fabrication of all the spar details. The
construction process is very straight forward, measure, measure, measure,
check all markings and measurements against drawing and then cut.

Initial layout of all parts helps ensure understanding of the positioning of
the parts and how they are attached. Then the part is aligned to position
clamped and, using the spar web doubler the part is clamped, pilot drilled
and clecoed to the web assembly..

I must say at this point that after checking the parts and doing the initial layout and overlay, the prefabricated
kit parts MATCH PERFECTLY. Sonex has done a great job in the design and fabrication of these parts.
While there is still a lot that the builder has to do himself, these preformed critical areas of the kit not only
save time but, ensure an accurate assembly if the plans are followed to the letter. Be sure to check,
understand the plans, measure, measure, mark, check and then cut.

| A special thanks is extended to Mike Dean who's exploded view of the right hand main spar, has made this components construction much easier to understand and complete. It is available to all on the Sonex plans holders site. Look under the under files section. |
Now I get to take it all apart again. Drill appropriate size holes, debur all
holes in all pieces, countersink holes where required and dimple where
required, protect for corrosion, reassemble and begin the rivet process.

These parts are starting to resemble a
spar for the Waiex.

Left spar complete as pictured. Only a slight bow . I guess I was lucky.
Many Thanks to Bob Adams and Chuck Dorff for all the info. The result is
at left. The right spar is also now complete. I will now be working on the
rear spars.

The rivet process continues. As these pictures were taken the left spar is
about 70% complete. The rivet squeezer I borrowed did not work as the
gap was to narrow. I have reverted to the Bolt method and as you can see it
works very well. Just a little slow.
