Default Hints for crawling inside the tailcone

Does anyone have any hints for how you went about crawling into the tailcone during construction? I'm at that stage now for my -6A build where the tailcone second top skin needs to be fitted. It's too far to reach inside for drilling and riveting.

I'm thinking that maybe some plywood or particle board cutouts to fit inside and over the belly skin sections would provide enough support and protection to be able to kneel inside.

Unfortunately the construction manual doesn't offer any suggestions! The canoe is supported on stands at the recommended height.

Pics attached of the setup as it stands.

TIA

Paul,

You are on the right track. Use 3/8 to 1/2 inch plywood cut to fit over the ribs, along with some styrofoam blocks underneath to support the load.

Mine were made in two pieces. One for the back half of the fuse and one for the front. Unfortunately, I don't have any build photos showing them....but I'm sure you get the idea.

Just remember to make it comfortable. You or your rivet bucking partner are going to be spending some time in there.

Have fun.

Go to Goodwill and go to the pillow section. They have odd ball pillows that usually sell for $1 each. I bought about $20 worth and just lined the entire tail cone of our RV-7 when we were running wires for a panel upgrade. Once I finished with them, I donated them back!

I did both. Plywood boards and then lots of $1 pillows from goodwill. I still have the pillows as they come in handy now for the condition inspection.

On my 7 I was able to do about 2/3 of that skin from outside the airplane. I started on the top of that skin and worked my way down both sides with my bucking bar hand up under the lower edge. Similar process to how you have to do the lower wing skins.

For the rest, I just laid a couple of folded up furniture blankets in the tailcone for my shoulders to rest on, with my butt in the baggage compartment and my feet fwd. I was able to easily reach all the way back to that bulkhead over my head and bucked while my wife shot them from the outside.

The picture below isn't the greatest, but it shows the furthest I had to get into the tailcone.

I made plywood platforms for my little RV-3B. It sure is tight in there!

Pillows and blankets from Goodwill are the best topped with wood planks. At the time I used garbage bags of packing peanuts under the planks….

after you do your best pillow and plywood job add a layer of cardboard. you can slide 10 times easier.i made a few hundred trips into a 12's last fall.

Plywood and an old 2" mattress topper foam. That was some uncomfortable work.
