Update!
Well I have been contemplating mirror polishing chrome plating my backbox hinges also. I needed to go to a metal finisher anyway as I have no chrome bolts for my coin door, so I ended up taking the hinges also.
so I droped these off in my lunch hour today and I should have them back in a week ready for fitting. I can then assemble the backbox onto the cabinet!
Also more progress has been made on the playfield, it's really looking great. Can't wait for it to be finished.
The next step I have to make as soon as the backbox is on is the pcb set. I have the stuff that was still in it in a box somewhere as well as some assorted pcbs I have purchased in the last 12-18 months. I'll dig it out the garage and provide another update, as once the backbox is on I need the brains to be working to control the playfield once it is put in!
