This is a toy crane that I finished earlier this summer for my son. It is based on the plans from Wood Magazine, but heavily modified. My son loves tower cranes and was very interested in pulleys at the time, so I designed what you see here. The hardware is rollers used on sliding patio doors. The wood is Maple and Walnut, finished with Satin Arm-R-Seal. The sticker is a custom sticker that I thought of on a whim and just ordered from a vendor online. I was pretty much done with it when he asked if I could make a place to put some toy people, so I came up with the “cab” that uses the holes in the mast that were already there. Turns out he likes to put the cab at different levels so he can get different vantage points! The only thing I’d change (and am considering updating) is using the lazy susan bearing. It is too easy to spin (I guess that’s the point though) and has some slop in it. Instead, I am thinking about just making some overlapping circle cutouts with wood.

You did some nice modifications on that crane. I can see where your son would spend lots of time with that. I really like your idea with the cab also. What did you use for the snatch block and where did you get it. I took the towere crane to him last week. He showed me and put in an order for the truck mount crane in the current Wood mag. I am planning on making some changes in it and one of them I don’t like the hook in the plans. I want to put a pulley in it and run the line back to the boom for a little more mechanical advantage.
I have the same feeling about the lazy susan bearing plus I am not sure it will hold up over the life of the toy. I am thinking abut how to use a bolt down thru the base of the tower and into a counter sunk hole in the platform. I haven’t figured out how to hide the bolt in the tower.

The pulley and hook are two parts. First, the pulley is simply a 3/4” (or 1”, can’t remember) pulley with a swivel end. Second, the hook is just a plain hook with clasp, that is mounted through the eye of the pulley. I got them at the big hardware store for cheap (under $2 each) and they are usually located near a section with ropes, etc.

I think I see what you are saying about the bolt idea. However, I’d worry that it may be too narrow and not be very stable. If you made the holes a very tight fit then it could work, and maybe add a big fender washer between the two pieces to provide a surface to slide against. I was originally thinking of making some interfacing circular pieces as wide as I could (~4.5” in this case) to spread out the movement and reduce the impact of any slop in the interface. Haven’t really thought all the details through though.
