Lots of resin dust, which probably isn't too good to breath, so I was careful.
There is a tiny gap between the cylinder and the wedge. I can live it it, but I may try to sand the wedge to make it so it fits both the cylinder and the ankle, if I feel particularly industrious.
All four pairs are mostly done.

Take some 220 sandpaper, wrap it around the cylinder and then work the wedge back and forth. You will end up with a perfect fit.

Thanks Alan.
The wedge actually fits the cylinder perfectly right now, if I move it off the leg and against the cylinder.
So I'm considering sanding the back of the wedge to match the actual angle of the flat face of the curved ankle piece when the wedge is flush against the cylinder.

Hi Victor, I ran across your blog searching for people who have built an R2D2. I have no experience in molding and casting. My question is, what are you using to create the molds?
Thanks
Terry
Terry,
The molds were created by someone else. Making the molds involves mixing other chemicals and pouring them over the part. The chemicals cures into a rubber latex-like material, and then the original part is removed and the mold is used to make the new resin parts.
There is a demo of the mold making process on the R2LA V DVD available from Michael McMaster at:
