Wing jigs seem to be a common topic of discussion, so I thought I would add a little fuel to the fire, and perhaps give you some food for thought. This information may be helpful to less experienced builders that don't have their own pet way of building wings.
The plane under construction is an Ultra Hobby kit of the Ted Fancher designed "Imitation" published way back in 1979 in the Sep and Oct issues of Model Aviation. That article is required reading even if you don't plan on building the plane.
This software doesn't allow one to caption each specific photo, so I will describe the two photos, and point out items of interest.
First of all, if you look closely, you can see that the laser cut ribs had leveling feet on each rib so the wing can be built directly on a flat surface. The only problem with this is that there is no provision to jig up the wing when it is turned over for construction of the second side. I'm a firm believer in securing the wing in a stable jig until the wing is completely built. With that requirement in mind, I fabricated the jig blocks that would secure the wing by the leading and trailing edges, both right side up and upside down
.
The jig blocks were cut out on a 10" table saw, and if you notice, the jig for the TE is two pieces that run full span. This was just an experiment, and in hind sight, I prefer multiple jig stations, because they can be fabricated with greater accuracy.
The jig blocks are lightly CAed to the plate glass which was leveled with thread, and shimmed as needed. The plans for the wing are under the glass, and used only for reference. The actual location of all parts are marked on the LE and TE pieces. Vertical alignment of the ribs is insured by the use of the 6" combinations squares. CA is used for gluing at this stage of construction. You will note that the bottom TE sheeting and the TE (previously joined) is already in the TE jig block.
The plate glass is 4' long, so the wing overhangs the ends by about 1 1/2 rib bays, which is not a problem.
At this point, the LE sheeting is added along with the cap strips, then the wing is unpinned from the jig and inverted for installation of the landing gear blocks, bellcrank, lower LE sheeting and cap strips and center section sheeting.
Hope this information is helpful to some. If you have questions, fire away..I'll try to answer them.
Cheers.
