I haven't been on the forum much in the last year or two because I haven't been building props for my haunt. I have been building sets or fixing old props or helping others with their props which always needs to get done.
In keeping with our plans to do a new theme every three years it is time for me to build all new props and sets. This is the first prop I finished so far this year. He has been built to point people the right direction when they get to our porch as many people turn right and walk into the house on accident.
The video shows him moving and at the end shows the slider crank mechanism that actuates his arm.
If you want a how-to let me know in the comments and I'll get it on the to-do list.
