Yes, I made everything myself. I did get my cousin to help. My youngest son stopped by twice and helped prime some of the wood.

Im adding a tunnel.  I waiting for it to be delivered.  Then I'll add the chute.

I may build a broad jump later. If not I'll use multiple jump in series for my broad jump. 

I got the plans on how to make the equipment.  I watched some videos.  Then chose the design or combination of designs to make ours.
