F-603, F-6103 or F-703

I'm in the planning stages (for many months) of a panel upgrade in my RV6.

In a thread on replacement panels from a couple months ago, Paul Dye and Mike Starkey recommended that a DIY approach was well worth it, and that it wasn't necessary to hire out the panel cutting to someone else. I'm going to give it a try. I may order an extra blank or two though...

I'm not sure which panel blank I need. The plane currently has an F-603 panel, which is 11" tall. I want to keep that format. Searching F-603 on the Van's site only yields the F-6103 OVSZ. Per the description, F-6103 OVSZ can be used in the 6, 7 and 9 tip-ups, and measures 14"x42", but has a (confusing) Q&A response stating it is 11"x42" (see the picture).

The F-703 description only shows the 7 and 9 tip ups.

Can I use the F-703 in a tip-up RV6?

I've been told some trimming/shaping is required no matter what I get, but it seems like if the F-6103 OVSZ works in the 6, 7 and 9, then F-703 would too.

I'm planning to give Vans a call later today, but thought someone here might be able to help.

Buy the F-6103 OVSZ. That is the only one they keep in stock for the -6 anymore. It is 14" tall. Just cut away what you don't need. The panel for the -7 will not work.

Side note, if you do have the panel cut for your 6, make it is a bit oversized. I have yet to design two -6 panels that were the exact same shape. Unlike the newer models, they are all a little different. Plan to file-to-fit.
 
Nice to see some people still cutting their own panels.
One tip: make a dummy panel from .025 .032 AL. That was worthwhile to me not only to test fit things for fit but also check the ergonomics.

Yes, go F6103 OVSC, more material is always a good starting point, & its wide enough to accommodate either slider or tip up, what ever your flavor.

Strip down your old panel & use it as a template for trimming it. Note, pay special care that the upper curve shape so your new panel doesn't interfere with the tip up canopy frame.

One tip: make a test-fit panel from .025 or .032 AL or even thin plywood. That was worthwhile to me not only to things for fit but also ergonomcis.

I've used Luan plywood from the local orange box store. Cheap and easy to work with to make a prototype.
 
DIY panel

It is not too difficult at all to cut your own panel, but as they say measure twice... which is what I did and got it right the second time.

If there is a sheet metal supplier/fabricator nearby then you can purchase one or more pieces of .063 aluminum sheet 13" x 42" (it does not have to be 2024-T3 alloy) and have them put in a 1 inch bend along the edge. This may be more cost effective than shipping from Vans, especially if you buy 2 or 3 to keep as spares.

Note the tolerances for the openings for the glass EFIS displays can be quite tight, so it's worth going slowly when filing the opening to final size. I put masking tape over the surface of the aluminum sheet to avoid scratching the surface with the jigsaw when making the preliminary cuts. The round instrument holes were made with a normal bi-metal hole saw in a drill press, and the smaller holes for the switches were done with a step drill.

A Father/Son team I used to play neighborhood poker tourneys with own a sheet metal business, but I haven't talked to them in years and they've grown into a big operation with a 64,000 sf building. I'll give them a call, but I need to order some stuff from Van's anyway.

I appreciate the tips though. I wasn't sure what normally gets used to cut edges or square corner holes in this the panels, but if a jigsaw works, great. Did you put anything sacrificial underneath to support the sheet when cutting? I've cut galvanized steel for new ducts and shortening a steel door, but didn't really care about the quality of the edge since I was going to bend and hide it. Any thoughts on how tough 24 gauge (.025) steel is versus .063 Aluminum? I know I'll need the correct blade...and some practice runs.

I thought I might cut from the back to reduce scratching. Do scratches show through primer and paint?

I supported the panel blank on a Black & Decker "Workmate" portable workbench while cutting, and worked from the finished side. The bench top has an adjustable gap in the middle and I just positioned and clamped down the panel so the blade would go through the gap. The masking tape protects the surface from scratching and I cleared away the chips frequently. If there is any minor scratching then the primer and paint will hide that. The aluminum is much softer and easier and quicker to cut and file than steel sheet.

If cutting a rectangle I mark it out carefully first with a fine sharpie, then drill a 3/8" or 1/2" hole in from each corner with a step drill. These holes are for the jigsaw to get started. The jigsaw cuts are made about 1/16" in from the marked line and then get filed up to the line with a mill file or vixxen file. The internal corners can be filed last, just enough to match the rounded profile of the EFIS case. A round chainsaw file of the appropriate diameter (5/32, 3/16, 1/4 etc.) works well for this.
