It’s been some time since I posted anything. I haven’t been able to spend much time in the shop for the last year or so but I hope that’s changing now!
I recently completed a marble run for my grandkids and after I finished I wondered if I shouldn’t have built two of them…one for ME!
The entire project was built from off cuts and scraps that I couldn’t bring myself to throw away and it has some of everything in it from purpleheart to plywood. After it was finished, I kept it for a few weeks longer than I should because I just loved playing with it! My wife said, “watching it just makes you smile!”
The few pictures that I took don’t really show much detail but I did record a couple of videos of it in action.

Here’s a link

Thanks for looking!

Also here’s a link of the kids when I gave it to them.

No doubt the absence relates to a matter that is now resolved.
I am assuming its not from losing your marbles!!

A what an amazing return project, ...yes you should always make two or in this case even more.

I just checked out the video,I am lost for words thats for sure.

It would make a great alarm clock thats for sure,
I can understand the smile!!

Good stuff!

Dennie – fantastic job! What a great project, can see why we haven’t heard from you for awhile. The elaborateness is incredible! Glad you made the video the way you did because I missed so much in the first run through. Those kids are going to go crazy! You should be very proud!

Just got back to my computer and I am humbled by the nice comments!
I have watched many YouTube videos of various marble machines/runs and most seem to involve some electric method of returning the marbles to the top.

I didn’t want the kids to “turn it on” and watch…I wanted them to be involved so I elected to make the counterweighted (is that a word) release hold 29 marbles and they would have to “reload”. I didn’t realize that they would be so anxious to reload that they would not watch the marbles as they went down the 4 tracks. Oh well, that’s what they do!

Again, thanks for the very nice comments and I look forward to “rejoining” this wonderful group of woodworkers.
and robscastle...I hear you…Alarm Clock!

And Jerry, I was very proud of the reaction of the kids…it made me smile!
Thanks everyone!

So impressive Dennie, fun, amazing and entertaining.A fantastic build something that will be treasured by your grandchildren forever.I can’t imagine even starting a project like this, you have to be a full-blown genius to pull this off.
I loved watching your grandkids enjoy this wonderful creation.

Thanks Jim! It is amazing what you can do with a few scraps and 300 man hours. :)
Every time I would complete a section I would have to stop and play with it! By the time it was finished, I think I could tell the wood species by the sound of the marbles hitting it.
