I made the coral effect by mixing PVA GLUE with POLLY FILLER 

doing the walls,

This is looking great so far! (I'm guessing you used the Tenth Doctor's console from the Character Options playset as a base?)

This really is coming along beautifully, kitkat! Are you also going to try and make the light inside the console white so the panels glow white like the War Doctor's, rather than green like the 9th/10th Doctors' console?

Dino.

yes I am, but there is a green circular panel that holds all the sides.on. so it will have a faint green tinge. But hopefully not too noticeable 

You probably have to use double-sided tape to hold on the bottom of the panels. I took off the green panel and it is pretty clear. If you got the Mk1 console of this model you're going to be out of luck for a War console since it's green not clear.

well i didn't remove the green under cover as i quite liked the cyan blue glow that came out when using white leds
