|Syringe Hydraulic Arm|
In almost panic mode I have been busy getting ready for College for Kids class I teach in a couple of weeks. At the start it looked like enrollment would be down and at the last minute it exceeded what is normally allowed for class size. This summer I am introducing the Syringe Hydraulic Arm for the first time and I am busy making up kits for this. There are many more parts than it would appear from looking at a completed prototype.

Part of the reason there is so much work for me to get ready for the class is I cut and drill eveything because the only tools available for the students to use are what I bring. This consists of hot glue gun, scissors, ruler, and a screwdriver.
|Tube Straps Hold Cylinder|
One of the ideas I had for the syringe arm design is to use the copper-plated tube straps to hold the cylinders to the frame of the arm. The right-angle bend is straightened in the straps but holes are already in the straps for bolts to go through. For the kits I also have used a large wood screw through the base up into the vertical part of the arm, this should be stronger than a hot glue joint.
After the students build this project I will have to create another post about how well the project went for them.
