I have mentioned in the past that I am not mechanically minded so I don't usually put things together but I decided I was going to give this one a try. My almost 16 year old, Rachel, and I took on the task. She is good at puzzles so I thought she'd be the best one to work on this with me. I have to say it was NOT easy. It took us 5-6 hours to get it put together. My husband did end up helping us at the end. I am not 100% sure I could have done it without his help.

There are several downloads to go with this including Fluid Power Lab which is an 18 page colorful printable worksheet style pdf file. The answer key is available online using the code printed on the packaging your kit pieces come in so don't throw it out. :)

(I didn't think he'd be able to pick it up , but he did.)
My conclusion is that even though this really took a long time to put together (it might not take others as long as it took us) it was really worth it. There is so much to be learned from putting it together and then using it (along with the Fluid Power Lab). The price is very affordable too!
Note that the hydraulic arm is not a toy and is intended to be constructed and used with adult supervision .
The Advanced Hydraulic Arm is available from Teacher Geek for just $24.39. (You will also need to purchase a Reamer ($5.95), Easy Cutter ($18.95 or use something similar that you have at home but this tool was GREAT! I recently used this to cut popsicle sticks for a project....it was perfect.), slip joint pliers and a #2 Phillips screwdriver. They also have an optional slider block that makes it easier to insert the dowels (they were really hard to insert). I think this would have made it a lot easier to put together so you might consider adding that as well.
I received this free in exchange for an honest review.
