I will be trying these air cylinders on the shovel not sure how well they are made but I'm going to find out. The main boom cylinders are 1.25" ID and the rest are 1.0625" ID. Hopefully the 5/32" tubing will have enough flow.... I'm going to find that out as well.

I also plan on using a full scale valve body and pump , I will need to change the operating pressure in the valve down to 200-250 psi and the pump will need to turn at about 1500 RPM to supply enough volume for the cylinders, not sure if I can get this all to work as I would like but it's worth a try...the other challenge will be getting it all to fit in the model....time will tell.
