Looks very nice Daniel, well done. With the hologram, might be worth experimenting with some of the ideas here

Like your hologram, mine looked perfectly green outside of the game but bluey green in the game. I have had improved results with the green mirror, but need to muck about a bit more with the setup
Thats so funny was just discussing this with my brother wonderinf if covering the mirror with green celofane might help low and behold some one has already made a kit and great price aswell wonder if postage will be he killer.
Thanks for the links
As for getting it done so quickly having my son wash and dry all the parts reallly helps. As he is washing im polishing the playfield and all the metal parts. usually have it bak together by teh time he has washed and dried everything then i polish each part that he has washed as i put them on. ALso having a drill with all the right fittings really speeds things up aswell
