Today the JAG steel feet for my second R2 arrived. I was able to purchase a set from another R2 Builder who was willing to part with them (pun intended).
These are identical to what I have on my first R2-D2. The gentleman I bought them from had already cleaned and primed them, so that saves me some time!
With the exception of some detail pieces, I have both legs, ankles and feet for the droid.
Now I can start doing some prototype work with some ideas I have for locking and pivoting the ankles for R2 to go from 3-leg mode to 2-leg mode (known as 2-3-2 in the building world).
In a few weeks, the foot drives should arrive, which is what R2 #1 has been using with great success.
I am also looking to make this droid lighter than the first. Things like using resin detail pieces instead of aluminum is one area I am looking to try.
