The Weird World of Dr. Madd

[packy120353]

Love that bolt thrower Dr Madd. Actually I love your entire weapon collection! I'll try to get some pics of mine maybe we can go Rhino I mean Vampire hunting one day!

[Dr. Madd]

I'll have to post pics of my airsoft pellet launching mini-blowgun, with a mounted laser sight.

A better view of the two firing mechanisms.






A close up of the firing locks. Yes, those are pipecleaners, My school of design often utilizes otherwise harmless items.

Today, my project was a hand-held throwing dart.





Made from....





The fletchings, made from plumber's tape.


Note the trifoil configuration. It gives the whole unit stability.





A side view of the fletchings.


The clear section is made from an eversharp pencil. It lends weight and sturdiness to the design.





The cap that holds the point, made from a bamboo skewer, is made from the cover for a ballpoint pen. The hook section from the pocket clip will later be used in conjunction with a Pana Slingshot.





The tip made from bamboo skewer, and taped into place. I don't know what the price of a dart is, but this one was made mostly from discarded items. . All I personally need is an office supply place or a department store and I can make stuff.



My apologies for the lack of focus.

The Purple Vindicator- made from plumbers tape, popsicle sticks, rubber bands, a craft plaque, dowel rods, and a binder clip.





Cocked. It fires a heavy short dowel rod 11 feet.

The front of the Vindicator. The bolt slides between the launch arms.





My Catapult. made from a wooden signpost, a craft plaque- wooden dowels, rubber bands a modified plastic spoon,  and a binder clip.

You will need

1 wooden sign post- one inch wide , lengths vary- found in any walmart DIY dept.
1 popsicle stick
1 one inch craft button- get one with a recessed edge on the face. This will be your bucket
between 10 and 15 office-supply rubber bands, the small, colorful ones work better.
1 quarter inch dowel rod

hot glue gun
drill
hammer- maybe necessary.
exacto knife
marker

step one

cut two three inch sections off the yard sale sign post. Save the rest for other projects
Plug in your hot glue gun.- give it time to warm up.

Measure off two sets of holes half inch on either side of the sign post sections. That would be half an inch in, half an inch up. Mark those. Drill them out.
Cut two three inch sections of the dowel, and using the knife, bevel the edges about an inch on each side. Don't over trim, but don't leave them too thick or it will crack the wood.
Using the glue gun and securely glue the button to one end of the popsicle stick.

Push the two dowels into the holes of one side of the signpost section, and do the same on the other side. Your pieces by now should resemble a square.
fit your rubber bands around one end, close to the dowel rods. Using your fingers, or a pencil, give the bands a twist by placing the object in the hollow between the edge of the bands- Note: I'm not good at describing this, if you can- I think you know what I'm doing. Fit the end of the popsicle stick into the bands once they are twisted to suit you, but leave the tail of the stick out to strike against the end dowel rod. It will be laying forward, but its designed like that.

Sometimes my weaponing hobby is dangerous, without shooting. I was replacing my slingshot's elastic, having cut off a bad place on the rubber, and managed to cut my thumb, and when replacing the elastic, lost my grip and got whacked in the mouth by the slingshot. I now have a cut thumb and a swollen lip.

"You'll shoot your eye out ."

PERFECT!!! 

[Dr. Madd]

Nah, I was wearing my glasses.

[Fester]

So was Ralphie . . .

[Dr. Madd]

Difference is, my glasses aren't broke. The slingshot escaped my hands and hit me in the mouth.

[Hepcat]

What happened to all the earlier pictures in this thread?

[Scatter]

So was Ralphie . . .

An excellent point. Also, Ralphie had to conjure up false tears to throw mom off the scent. Doc's tears were the real thing.
