Frise Aileron Leading Edge Alignment - Labor Only

Have a SeaRey LSX Kit, or purchased the Frise Aileron Upgrade and don't want to deal with assembly of the Frise Leading Edges?  The Searey Specialist has set up jigs for alignment of the metal.  Why is a jig needed?  We've seen several issues with them: 

1) Very easy to get a twist along the leading edge

2) Several of the parts that have arrived were skewed when made.  Meaning the material wasn't placed square into the form used to make the airfoil.  If you have a part like this (not easily evident either!) then attaching the straight edge along the leading edge tube WILL induce a twist along the airfoil.

Enter the Frise Jig:  I modeled the entire aileron into Solidworks and then sliced the aileron to produce the airfoil at different stations along its length.  As the aileron trailing edge is tapered, its thickness also changes from the root to the tip - therefore the airfoil varies.  Then cut the airfoil stations and build a jig base to attach them to.

To assemble the ailerons, the aileron frames are built as shown in the kit manual.  Then we insert the Frise parts (the sheet metal shaped airfoil) into the jig stations.  A long rod is placed along the leading edge that is tapped, and using draw bolts the Frise metal 'apex' is pulled into the jig into the correct location.  This makes the Frise metal nice and evenly aligned along the aileron leading edge, and corrects any errors as noted in #2 above.

Once the metal is locked into place, the aileron is slid into position with the trailing edge against the 'back stop'.  Then drill / cleco both sides, and mark the positions of the 1/4" holes for the eyebolts.  Finally marking / trim any corrections for miss-alignment along the aft faces.  Remove from the jig for any final trimming and deburring needed.

Note this price is for setting the alignment of the Frise metal on the LE only.  It does not include assembly of the aileron itself.  Shipping is not included and cannot be accurately quoted by the website system.
