Fin material

[Mark Chen]

Estes I think it was who used to make a model with tubular fins like that and I can remember wanting one so bad when I was a kid but I had no money to buy one, so I made my own out of the cardboard tubes that they mail posters in. I even made a nosecone from balsa wood by whittling it with a carving knofe and sanding it smooth. It took forever to get it right. That brings back fond memories!

I think it was named Totally Tubular. If not it would be a good name for a rocket with tube fins. Later Reno

Corrugated plastic is a good material to use. You can always glue fins to ahve double thickness. I use single thickness and they havent failed yet due to a flight

We just held our elections and the groundskeepers where I work just collected all of the political signs from the parking lot and threw them in the dumpster. Some of them were made of that corrugated plastic you speak of. I've got about 6 pieces about 20x30 inches in size. That should last a good long time.

This is a good way to get material for no cost. Everyone should check around for discarded signs.

I bet some of the people running for office might have leftover signs you could ask them for. Tell them you voted for them and want a keepsake.

That's a good idea. I will check around and see if anyone wants to contribute. Thanks!

I saw people stealing the signs before the elections. Water rocketry must be getting really big these days.

hi chriswaterrocket

i like that idea for the fins and i have tried it, they work really well and are easy to replace if they get damaged or lost. those types of fins are really strong and don't bend!

Great idea!!!

Balsa Wood is the awseme. I'm using it right now. sweet. sand it down into a nice cshape, very strong, no bends. very light. really handy

Here is my tip: if you make thin sections or sand air foil shapes or delicate parts from balsa you can paint them with CA glue and it will make it very strong so it will not damage so easily.

Indeed. They work awseme for model rockets.
