n00bs Gonna Build a Carden

Dirty stinking foam rats!

Gareth,

You are seeing one benefit to Cardens.. the infinite ability to fix them!
GET R DONE. (that's the Ohio version. We change the "I" back to "E")

Gareth,

I was wondering, does anybody use anything to "seal" the exposed foam parts (like your cheek ) with something like a urethane(that might eat it too) or anything that would not add too much weight???
It would be great in critical areas that are near fuel tanks, but then again if you have a fuel tank leak, you would have to seal "ALL" exposed foam inside a fuselage,
Just a thought

Doug, I had the inside of the motor box covered in 1/32" balsa and painted with a few coats of clear polyurethane. It don't know how whatever it was that got in got in there. It didn't drip down from on top because you could not see the damage from there. Its like it came up from underneath.

Carden is sending be a new belly pan, cheeks and firewall. Its a long weekend so I might get it all done by Monday. Plan was to have the re-fit done by the end of the month.

On my Carden I will be speckle painting the whole fuse including the foam pieces. I have tried the speckle paint I got on the left over shucks that I have and it did not eat away any of the foam. Seals the oarts off while looking good

35% elephant maybe. Don't be hatin' you can't wear flip flops because of your nasty fungus toenails.

The poly glue was setting up really slow this weekend. Still I got some work done:

Holes in the lower can tunnel area where sealed up with 3 layer balsa ply (3 layers of 1/32" glued together with poly glue).

The new firewall and extension block were cut and drilled. Everything was drilled at a 2.5 degree angle to match the right thrust provided by the SWB extension block. The back of the firewall was countersunk with a forstner bit so the T-nuts don't get twisted. The bolt heads and lock nuts will all sit flush so there are no pressure points. The design is basically the same as Walt's design on TBob's Yak.

Got the new foam parts sheeted and started putting then in place:

I bought a new tool, a spindle sander. This thing is bad to the bone! Its got a slot for a real man miter gauge and the dust collection is much better than the bench sander I had before.

I don't feel so bad about putting a flip flop through you turtledeck now. I loan you my tools, bandsaw and sander, and all you can do is complain about them.

Hey gareth, are you just going to use standard mufflers on the 100?

[gareth.ky]

Yup. Thought about pipes but I can't afford it and I don't want the hassel.

Dude looking goooooooood

i'll be starting my 35% 260 very soon!have you guys seen my 40% vid??

I made the belly pan this weekend and it is kind of cool. I've seen these angled chevron type slots cut in the bottom of composite airplanes and I wanted to do the same thing in Balsa. I didn't bother on the original because of the canister but that's never going back in.

A single piece of balsa would be too weak so I made up some balsa plywood. I measured to determine the thickness and I discovered that the foam belly parts highest point is 1/8" taller than the gear plate! To hide this I sanded the part so that it all blends together. To give myself enough material to sand away I made the top layer of the balsa ply 1/8" thick.

Cutting all those vents on the scroll saw would suck. Not to mention the total mess the scroll saw would make of the wood. This is what stopped me last time. So I got some MDF and made a template so I could sand them on the spindle sander.

I cut the ends with a Forstner bit and rough cut the edges on the scroll saw then cleaned it up on the spindle sander.

Here's how the first side went:

To made the other side you just flip the jig over. I'm happy with how it came out.

Nice work!

It was icy in Oklahoma last week. I took advantage and built a new freezer:

The firewall is on. I used some 3mm bolts to hold it in place because, like all plywood, it was a little bit warped. Clamping would have been hard and the bolts were easy. I also drilled a few lightening holes and capped them with some 1/8" balsa.

Doing a few other things. The tail gear plate had to go to build a new mount for the J&J Tailwheel. the T-nuts for the main gear were rusting so I'm replacing them with brass threaded inserts. the holes will get capped so fuel or whatever cant get in there again.

And now a question: The T-nuts in the wings, are bit loose. They got cross threaded and I tapped them back out. Any idea how I should fix this?
