« Part 2: Getting the push blade set 2 Part 3 of Toy costruction series Part 4: Tower build day two »

I got started on a tower crane today while I wait for my Toys and Joys plans to get here for the Excavator.
I’ve got the plans for the Woodstore.net Excavator but I want to try my hand at making the tracks and could probable figure them out but why reinvent the wheel when all I have to do is wait a couple a days and get it right.

I know there’s a lot of info here but I figure if your looking at this blog your interested in how it was built or may be getting ready to make your own.

While I was building the Dozer I kept seeing the tower crane on one of the plan sheets and it looks simple and I’ve got a bucket of mahogany 24” slates that were part of a crib I scrounged up awhile back so it’s tower crane time.

Yesterday I got on google and did a search for cranes and came up with this one page plan [on the wood store sight it was free] which showed the width and length of the base. 4 1/2” x 11”
That’s all I really need cause the height will be the length of the slates I’ve got 24”.
This will mostly be made out of mahogany scraps what little walnut I’ve got left I want to save for the excavator.
Here we go with the wheel base.
I used a 2×4 for the center part and added mahogany to widen it and hide the pine.
You can see the plans in the back ground.

Then I glued up the base for the tower.
I’m using 3/8 dowels to mount all the parts.
On the store bought plans everything would be made with 3/4 lumber but my slates are 3/8 so I just tripled up on the parts which just adds to the look I think.

The tower and the crane arm are not glued in yet.
I’m building this as I go so need to be able to take it apart if something doesn’t look right and needs to be changed.


The control room will be glued to the main tower and is used as a stop for the arm.
There’s no need for it to go any lower.
I’m thinking about not having the drop for the cable in one stationary place out on the end of the arm.
May make it like a real tower crane where the cable can be brought closer to the tower to pick things up.
I hope that make sense?

There’s not to many extra things you can add to this project.

Next I’ll be figuring out the pulleys and cranks.
Need to add some counter weights.
and I think I’m going to make some wheels???
A really crane like this wouldn’t have wheels but hey it’s a toy, but for a little realisom I may add some of those hydraulic out rigger arms so it won’t tip over if you turn it to the right or left, we need to do something to spruce it up. lol
I’m having fun hope you are.

Do not use the lazy susan hardware for the pivot. It wobbles too much. It would be better to use a dowel for the pivot or an axle for a wheel. I built that and the lazy susan hardware is a weak point. Your modifications will make that into a very realistic toy.
