« Part 2: Finished Part 3 of Toy building series Part 4: The Concrete Pump basic truck »

I have built all of the toys in Wood mag. construction series for my grandson. Last spring while visiting my daughter she wanted to know what toy I was going to build next. I told her none I was through. Somehow concrete pump came up in the conversation. My grandson got told to ask me to build him a pump truck. I told him he needed to talk to santa. His response (typical 4 year old) was santa build plastic toys, grandpa makes them from wood. I came home with a project and no real idea how to do it.

Sketchup can be your friend. I did take a class in Sketchup again at my local Woodcraft and as there were only two of us in the class got a lot of information and how to on what I needed to make Sketchup work for me.
The internet can also be your friend. The Putzmeister and Schwing sites had lots of pictures and dimensions.
I ended up basing the pump of a Putzmeister 56z and going with a 1” to 18” scale (loosely).

I was able to use the Wood construction crane basic truck and modify it to fit my requirement. The fun then started, outriggers and boom. I came up with the below design.

Drawing up the boom was a real lesson in sketchup and animation. I also got out the poster board and drew up and cutout and fit the boom parts to get an idea of scale and how they worked.

It is now June and there is fishing and whitewater to run this project went on the back burner but gave me something to think about over the summer. A grandson kept asking where his concrete pump was all summer.

I do want to see the finished project!

Building the toys from your own designs will have a really nice feeling—wen you see his eyes light up—and know—YOU CAUSED IT!—all the way!

Now that’s pretty special Bruce, from request [grandpa makes them from wood] to learning how to make it happen and now actually building the project; very impressive – WELL DONE SIR…...
