Hello again everyone, sorry about the delay been busy lately, but at least there will be a nice long post as I have now almost finished the mod. There has been a change of plan from using the fan to a servo now as I can easily gear it to move at the right speed. [/IMG] [/IMG] Next I drilled a hole for the servo head to fit into in order to drive the cog. [/IMG] [/IMG] Before I started on the 'cog and piston' I gave the side panel a respray in copper and finished off the edging around the windows to make them stand out more. [/IMG] Time to work on the cog and piston The Cog was cut out of plasticard and then filed into shaped with the help of some clippers. [/IMG] This was the sprayed black ready to be painted to make it more rusty. [/IMG] Next I got to work on the piston and how it would be able to slide up and down. Drew a few sketches first. [/IMG] This would also be made out of plasticard and then painted later. I was made using 3 layers of plasticard in order to make a slot in the middle for the arm to run up and down. [/IMG] [/IMG] I used an old circular servo arm as the runner and chopped down the sides so it would fit. [/IMG] [/IMG] Next I started work on the piston. This was also plasticard with some metal bits I found in a draw at the end. Have not got a clue what they were from. All of these were then sprayed black. [/IMG] [/IMG] [/IMG] The cog now needed a point for the piston to rotate around and this was just a screw with some plasitcard to raise it off the surface. [/IMG] This was all then attached to the cog and servo and then stuck on to the panel. [/IMG] I then started to paint some detail onto the piston mounting. [/IMG] At this point I started to work on the motherboard. I painted the cpu fan and also added several details which were built out of card board then painted. [/IMG] The overall affected I was quite pleased with. [/IMG] Next I decided I needed something to cover my hard drive so ... out came the warhammer again. I painted up some panels which could fit over the hdd. [/IMG] In the end I decided on this one. [/IMG] [/IMG] More work has been done but I have not taken any photos yet hope to update soon.
