Internal metal framework

Denny came over and helped me get R4-ED's outer R2 legs centered and held the legs steady as I drilled the threw bolts. Then I ground the bracket mounting bolts flush to the frame.
After a bit Dash showed up and we continued to to work on his wood frame inner bracket. He is thinking of calling his wood frame astromech R2-DR.
Now that ED's internal frame support was done I started cutting some of the parts for Jen's R3-PD frame
After a while of welding and drilling, Dash's wood frame is sitting up by itself.
