Light sabers, painting and power couplers

It’s been a while since my last post, but I’ve been quite busy researching various parts of my R2-D2 build. Ofcourse I got a bit distracted by my new BigBox printer, and ended up printing a light saber, which is going to be my airbrushing test object.

Speaking of airbrushing, I’ve been trying various possibilities for the metal / aluminium parts of the build. I’ve painted some sample pieces with Vallejo metal paints (aluminium, duraluminium and chrome), but have not yet been really impressed.

I do think I want to go for the not-so-shiny look of the dome from A New Hope, but won’t know for sure until I’ve also tried the solvent based Alcad II paints. I have 3 colors (aluminium, polished aluminium and chrome) to try before I can decide, but given that I need to paint that stuff outside, the gloss black primer is going to have to sit there till the weekend:

I did manage to get a bit of work done on the power coupler model, which was needed as the parts didn’t really fit together the way I had imagined they would. The fit is still a bit too tight, and I’m a bit worried that applying XTC-3D will make that even worse, so I might add a little bit more spacing.

All in all a lot of research, but all slowly taking me closer to actually building R2-D2.
