Hello fellow members. I hope all of your Halloween projects are going well so far this year.
I had a member request a specific mechanism from me a few weeks ago for a project he's working on and I thought I'd post it and see if anyone else would like one as well.
I want to be honest here because I can not take credit for it's theory of operation. This mech is based off of Frightprops.com's design. I basically just built it differently using a little different design and steel, and hopefully overall just a little bit better One thing I do know, is that mine is much more inexpensive, seeing I do this as a hobby, for the love of Halloween, and really don't make much off of my props.
Here are links to frightprop.com's mech and how they use it:
Attached are pics and videos of mine:
My "Jumper" mech has a heavy duty 4" x 1 1/2" x 2ft steel channel for the base, a similar 4" x 1 1/2" x 6" channel on the top, and 1" square steel legs. I've used iron reinforced, oil-impregnanted bronze bushings for the pivots, grade 5 hardware, a double acting 1 1/2" bore x 8" stroke air cylinder, a 24vdc pneumatic valve, adjustable flow controls for adjusting the speed at which it goes up and down, and I am also including a 24vdc power adaper and pressure pad. In the low postion, the top of throw bar is 20" off the ground, and in the high position, the height is 40" off the ground. All you need to do is mount it to something secure, add your prop, plug it in, connect air pressure and you're ready to go. I can suggest some different routes you can go as far as adding sound and programming it if you want...just ask!
The cost of my "Jumper" mech is $350 which includes everything I stated above and shipping to the lower 48 states.
