Wow it is smooth and the vertical distance is very good. I'd appreciate some additional info on the build, as I built one two years ago but I had a number of problems with it. I couldn't keep the arms aligned and the connectors kept either tightening up or loosening depending on which direction the motion went.

I'd appreciate knowing what type of connectors you used. The dimensions of the arms and position of the fasteners to achieve that smooth movement.

I had the wiper motor as a side mount; thinking your design with it in the rear helps keep the arms aligned. Plus I used aluminum screen frame for the arms, maybe I needed larger material.

thanks for the video and inspiration to get mine working; I'd just about given up.

Tks!!!!

Good idea. This would be good for a tombstone peeper, but lacks the high speed scare of a pneumatic jumper.

Thanks everyone!!!

One of the important things I learned awhile ago was to use nylon locking nuts when building moving parts like this! using them will keep the bolts from tightening or loosening. Make them just tight enough to keep things from wobbling but not so tight it makes things bind up. Also be sure put washers between moving parts as well this also helps to keep the nuts from becoming tight or loose. I attached the rods to the wood using simple wood screws with a washer in between the wood and the metal bars. again I made the screws just tight enough to keep it from wobbling and nothing more. I picked the motor position because i felt it was the best place to help keep the movement nice and smooth also the motor only has to pull in this position not push and pull as it would in another position. Hope this helps!!! And yeah it might possible the aluminum you were using was too thin as I mention I got this from Homedepot and it was pretty cheap

Nice! It's very smooth and looks like it will last for many Halloweens.

And, thank for taking the time to make such a detailed video with explanation. This stuff helps us folks immensely. :)

Great prop, BIGANT ! I used a similar mechanism on my motorized Bride and Groom skeletons several years ago.
I'm not at all into pneumatics either.

Another great idea, looks good! For those of us (myself) that are completely mechanically challenged, the bar that you connect to the motor...do you bend it yourself or is it possible to purchase something like that to use? And do you just drill a bunch of holes hoping 1 is right or is there a basic hole measurement and hole size when you are using a wiper motor? I did a tombstone leerer a few years back using pvc and every Halloween without fail it comes apart on me Halloween night. The only other thing I've accomplished (actually my son helped) is a lifting coffin but got lucky with that one using a straight piece, metal L bracket, and a lot of swearing. I also have a cauldron creep all cut and painted that's been sitting in a box for 2 years now because I have so much trouble figuring out how to connect to the motor and no hubby to offer advice. I am completely ignorant when it comes to even simple mechanics. I'm thinking of a ship's wheel this year too and once again need to figure out this basic connection. Too bad there wasn't a Using motors for Halloween props for dummies! Would appreciate any advice you could offer. Thanks.

In this case I built that arm on the motor but you can easily buy one as well if you wanted to. Frightprops sells a few different arms for their motors. This one was easy to make I had a piece of aluminum flat bar and simply bent it using a large table vice and drilled a few holes in it. its not perfect the angles are a little off but it works well enough to do the job. the best advice i can give is to walk around lowes and home depot some time and just look at everything there and try to get ideas of how to make things work. also check out youtube as well. I often times look at wood working videos and take inspiration from them as thow to make foam props often the techniques are very similar. also never be afraid to try something worst case it doesnt work and you have to try again!

Great Job!
I like the design.
I recently switched a pnuematic prop to a motor.
Sometomes a slow motion is a little creepier
