Axworthy pulley setup help

7201 Views 16 Replies 10 Participants Last post by  Dano Howard
I am trying to build an Axworthy flying ghost. I have scoured the internet, this forum and other Halloween related forums, photobucket, and Youtube but I cannot figure out how to attach the pulley to a rod/screw without it tightening on its own to the point that it does not rotate.

I am using laundry pulleys which are less than 1/4 in bore so I cannot use 1/4 bolts (it would have been nice). I have included some pictures of what I am trying to do. I will be using a wiper motor. A V-belt will drive the pulleys. I have used a 3" 10-32 machine screw as a rod to the first set of pulleys. It is attached to a bracket so that the height of the pulley matches the drive pulley on the motor. I have put 2 nuts, then a washer, then 2 laundry pulleys (which have been bolted together to function as one), then a washer and then a nut.

When I rotate the pulleys, the nut (from the side closer to the bracket) tightens up and the pulleys stop rotating. Any suggestions as to what to do or how to fix what I am doing so wrong?
Thanks!

axworthy ghost help please

I always try to keep my eyes open for motors for you guys and gals to put in our used items section on the web site.
Once I find one, test it, clean it and what not and post it, it's usually gone within 48hrs, people watch that section on our site like crazy because we put stuff in there for cheap just for you guys and gals.
The best motors in the used department we have found to be the following because they have a frame which saves you all a lot of headache, the speed is always good, best of all they are rated for continous duty and the shafts are usually long allowing for clearance and the power is enough to break fingers:D which is exactly what you want.

CONCRETE AND PAINT MIXER MOTORS - Usually 1/4hp or 1/8hp
ICE VENDING MACHINE MOTORS - Usually 1/8hp
INDUSTRIAL VAT FOOD MIXER MOTORS - Usually 1/2hp
CONVEYOR MOTORS - No telling
GIANT CLOCK MOTORS - Usually 1/6hp
T-SHIRT PRESS SPINNER MOTORS - Usually 1/4hp
My Favorite - X-Ray Machine Motors :eek: Usually 1/2hp
WHEEL CHAIR MOTORS - 1/2hp

We should have some motors coming in next week.
whats the best line/rope to use for high tension/strength for heavier ghosts?????????
