Materials for spars (from 1995 discussion)

Date: Wed, 8 Feb 1995 09:32:51 -1000 From: tanaka_be@swam1.enet.dec.com (Bert Tanaka) Message-Id: <9502081930.AA09897@mts-gw.pa.dec.com> Organization: Harvard University Office of Information Technology Subject: New Product - Improved SkyShark 2P rod

I got a set of the new 2P spars from SkyShark and tested them in my Legend IQ ultralight that normally uses the 3P spars. This is a nice 8 gram rod. The old 2P was the same diameter as the 3P, 5P and 7P, which made it convenient because it was interchangeable with the same fittings that are used on the other rods. Although it had a pretty good stiffness to weight ratio, it was also a bit fragile for the heavy use and harsh flying that I like to do. I've never used them because I could break them so easily.

This new 2P is made with a smaller diameter. A concept Erez says that was suggested by David Lord. I believe he used the diameter spec Dave suggested when the new mandrel was selected. Otherwise, it appears to have all the same characteristics of the old rod, except that it is much, much tougher.

I've been flying with it for a while now and have been doing a lot of ground rolls, tip stabs, coins, cartwheels, and hard snap stalls (basically, I've been trying to break them!). Ground work and hard snapping maneuvers will weaken a rod but so far, this new 2P has held up wonderfully. This one is probably tough enough to accept a set of Power-Tite connectors which help to stiffen up the frames made of light weight spars. At any rate, it has proving to be a very durable performer for me.

Good Winds, Bert

Thanks for the great info Bert! How do you think these spars will hold up (in terms of toughness) to other SUL spars like the G-Force?

Don McCasland at Kites of Boston has a pretty good stock of spars and can order anything that he doesn't have.

I can provide small numbers of spars for repairs and such. I don't really do retail, however, but am happy to help out if you need something on the field and I have it with me.

I highly recommend Tom Marvin at Hang-em High Fabrics in Richmond VA. Tom has all sorts of spars and fittings along with Icarex and regular ripstop nylon.

Another good source of spars is the High Fly Kite Co in New Jersey. Fran Gramkowski has lots of experience with all sorts of kite spars.

No more fiddling with set screws, stripped threads, looking for Allen keys. Connect your push-rods in a split second!

Earth magnets grip each section of the push-rod together to withstand the most rigorous workout.

Each KLI-Cons™ magnet set comes with a special threaded brass connector, which you solder to the end of your push-rod.

Add an airhorn to your model


How to Make a Medicine Bottle Air Horn


from wikiHow - The How to Manual That You Can Edit

An air horn brought from the store will only last as long as the compressed air inside the can does, but with a few household items, you can easily make your own air horn that will last quite a long time!

Steps


  1. Using a heated screwdriver will make it easier.Poke a hole in the cap, side, and bottom of the medicine bottle. Size does not matter, except for the hole on the bottom, which should be large enough for a drinking straw to fit snugly into.
  2. Take the cap off the bottle. Cut a piece of a balloon and stretch it over the top of the bottle. Secure the balloon with a rubber band. Replace the cap on the bottle.
  3. Cut another piece of a balloon and stretch it over the bottom of the bottle. Secure it with a rubber band.
  4. Poke the straw through the hole on the bottom. It might be helpful to first poke a hole in the balloon.
  5. To use, blow into the hole on the side.


Video



Tips


  • Use a heated screwdriver to make poking holes in the bottle easier.
  • If it's not working, try moving the straw up and down.
  • The straw should be longer than the bottle itself.
  • The larger the straw (in circumference), the louder the sound will be.
  • Making the hole on the side larger will make it less of a strain on your cheeks to blow into it.


Warnings


  • Do not use this air horn near anyone's ears; it could cause hearing damage.
  • If using a heated screwdriver, exert caution not to burn yourself or to breathe in the fumes of the plastic.
  • Exercise appropriate caution when using edged tools such as scissors.


Things You'll Need


  • Medicine bottle
  • Scissors
  • Balloons
  • Drinking straw
  • Rubber bands

Model Jonesport Lobster Boat Lines circa 1930-1940


Three of Dave Mainwaring's Jonesport lobster boat display models, plank on rib, early construction stages. One in the background is 32+ inch and two hulls in foreground are 17 1/2 inch. Future models will be built with transoms installed with the planking. They were built over male molds.




















There are abandoned vintage Jonesport style hulls scattered on the shores. Driving through the area from Corea to Damariscotta, Maine you will sold wooden lobster boats passing away in driveways and fields. You will find some of these boats advertised as 1940's lobster boat available free on Ebay. You will also discover as many cabin and deck arrangements as there a hulls. I have photographed many of boats riding at anchor so model builders can see one t use a guide. http://fishingboats.blogspot.com/

In my search for early Jonesport lobster boats I surface a picture of the bone yard in Jonesport Maine.
