I have two very old scaffolding I brought at a auction years old. Used them to do roofing on my house and garages. To use them for scaffolding I use two 2x4's 12 foot and a 2x12 12 foot long. (one of my ramps I used to load garden tractors on my pickup.
I have a three foot extension to use with the scaffolding. Using the extension it well go up to around 10 feet. Never used the extension - a little scary walking on a 2x12 10 foot in the air.
I had them setting out back of one of one my garages. Have no used them for years.
I was using two step ladders with a 2x4 between the ladders.
I saw them one day and said to myself they would be easier to setup around than the two ladders.
Been using them this year to paint parts outside.
sorry no picture of that.
So one day I was painting some parts outside and I paint them.
I have been pulling motors in the garage under my overhead storage area.
I wanted to be outside to pull a motor so I got the two scaffolding setup with two 2x4's. Put my chain hoist on it. Work great had more room to move around then inside the garage.
