I was asking because I am curious if people build wings for cubs and such with fixtures. It has been my experience that regardless if stuff is pre-drilled, you can still put unintended wash into a wing if it is not built properly or set up properly. On a cub it is likely not as worrisome as it is on a higher performance aircraft. I have seen and had to rebuild some seriously messed up attempts at building wings in the past. It really is scary what some people will attempt.
We had some Corsair wings in the shop years back and they were seriously messed up. We ended up having to "borrow" another Corsair to build fixtures from. That costs big money unfortunately as most people do not normally lend out aircraft to be taken apart. Another shop I worked at used the P-38 we used to have to build a complete set of fixtures from it. That action will likely insure another 4 - 6 flying P-38's from stuff that years back was considered unusable.
I'd like to see pictures of your project if you have time in the future.
I served an apprenticeship, and worked as, a tool & die maker for the first half of my working years (after the Army). I worked in a bunch of different shops doing prototypes, building new dies, repairing dies, building new jigs/fixtures and repairing existing jigs/fixtures that were in use on the production floor.
I would think that it would not be very cost-effective to build or commission a jig or fixture for a one-off repair like this.
I have made some form blocks for the plane that I am scratch-building, and some welding fixtures for when I weld the tube frame. These are needed due to dimensioning tolerances that must be adhered to and for holding parts in the correct position when welding. I did contemplate making cutting/stamping dies for the 190+ wing ribs that I need to hammer out, but after doing the math, the cost of tool steel, heat-treating and the need for a (minimum) 20-ton press, just to make the ribs, would cost about the same if I bought them already made and alodined. I could also have most of them formed by the time I had the dies ready for production. The only dies (to use in my 10 ton press) I did make, were for flanging the lightening holes in the ribs. I knew that I wasn't going to sit around flanging them with a notched wooden stick while I watched TV.
