Tip de jour,
I was a little worried about cutting the holes in my instrument panel. I have gone for a three screen GRT EFIS/EIS setup and only have about 1/8" to 1/4" to play with to clear the Left Hand Side EFIS from the F1045L rib. For those to get to this point, here's how I tackled it.
1. transferred the initial panel design from E-panel builder to TurboCAD
2. printed the panel layout onto clear A4 (8 1/2x11") Avery labels,
3. cut some perspex to match the LHS of panel and stuck on the label
4. cut the GRT efis hole in the perspex to the template on the label and mounted the EFIS
5. clecoed the perspex with efis to the fwd fuse and checked rib clearance. (I needed to drop the EFIS another 3/16" to clear the rib).
6. transferred the revised measurements to turboCAD and reprinted on transparent labels.
7. stuck the labels to the panel
8 cut the round holes with a 2 1/4" hole saw on drill press. Panel clamped to press table to prevent movement.
9. cut the rectangular holes with a jigsaw (saber saw to you guys) and hand filed to the line.
The final cutting/filing of the panel took less than a Sunday arvo and I'm really happy with the results. I can recommend the trick with the clear adhesive labels to get an excellent view of how things appear on the panel, and then use as a cutting template. - and for a small fee I can tell you precisely how far up from the bottom of the panel to mount that EFIS ;->
hope it's useful
cheers,
Ron
