My Invention

[zoelra]

Hello James,

Sorry I was really busy over the weekend and didn't make as much progress as I would have liked.  The stand for my old 2SO would not suffice so I came up with the idea of mounting the main lever on the wall in my garage.  I added an additional bar above the lever that will hold the pulleys for the lever.  You may want to consider this approach as it saves time on making a stand.  The picture I have attached shows where I am headed.  I do plan on getting as close to your specifications as possible.  My goal will be to validate your idea that the counter weight will be able to reset the pendulum to it's initial drop height.  I'm glad to see you are planning your build.

My picture is not showing up in the previous post, but the link works.  Anyone know why?  The filesize is 468K.

  Not a bad way to about something. I put an x about where the pendulum would need to swing from.
I'm going to try to think of a simple way to catch and release the pendulum. Actually, think I already have.
I'll post it later.

@zoelra:
It's a well-known forum glitch, usually resolves in an hour or so. I see your inline image now. Don't fret, as long as you see two listings of the attachment, it will eventually show up as an inline image as well as the download link.

As is, the main lever is just over 4' long, (2'+ on either side of the pivot point).  There are holes drilled every 6".  The length of the pendulum shaft is 1'.  Each of the weights is 2.5lb.
