Background
Bought a duotron with hope of converting to my Arduino based solution i have used on my flying carpet. The aim was to be able to replace playfields and play different games no space for a games room have my rockola world series and a jennings one armed bandit in the kitcken already. The duotron was going to provide the cabinet and metal work however machine left for 20 plus years in barn and on opening it was full of woodworm, water and mice had got in so not salvageable. Good news picking up a clean cabinet and backbox tomorrow.
Back to the point I need some help the playfield was completely in tatters managed to sand down straight it and fill were wood had delaminated. Made a new overlay over 100 hours work no wonder they cost so much, it is fabulous here is my problem there are 2 longer post as per the gottlieb playfield schematic and i have no idea where they belong any ideas, also attached is the door before i start to refurbish.

Thanks for the post position

Finally pickup my gottlieb cabinet backbox and door. Tried evapo rust did a good job together with a light sand blast but will use my new door. lock bar and coin metalwork ok after treatments. Currently stripping a chicago coin fiesta lots of work here to do. Have new plastic cut for the duotron and my flying carpet just need to get the artwork sorted.

Playfield update
I scanned the existing playfield and found a playfield on one of the Virtual pinball sites. Be careful VP playfields are all wrong resolution and sizes. However between the 2 i was able to make the overlay. I started my making a blank the correct size and then inserted the scanned files. I used affinity and inkscape for the creation. Printing checking hole alignments is critical. When that was all done you need to find a printer who can print in full colour and can print white. The printer i used required 2 files a high resolution cymk raster file and a dxf file to define the white areas. I believe they print the colour first and then overlay the white ink. By the way the base material is clear. When you get the print you can attach it using a wet or dry method i tend to use the wet method as the water can easily be pushed in the playfield holes. Hope this helps, by the way it took over 50 hours if the playfield is in bad condition also the scanned files will almost certainly be out of focus unless you can use a large flatbed or see thro scanner. PS i used clear inserts beneath the playfield and included the scoring on the print this makes sure it is perfectly flat. 2 options are availsble to seal the overlay a 4k sealer or get the printer to attach a protective coating.

Update
I also created a new backglass as well.

Update,
The backglass was created by myself, I scanned my original backglass not in good condition and then proceeded to create a ne backglass. My first print was not perfect but acceptable. The leason here is simple understand RGB V CYMK printing. Fo tose non technical is like the picture on your TV v the print you have from a family holiday, transmitted light ie led is different. Sorry not a photo expert but it is different. This another reason why replacement playfield and backglasses cost so much a lot of experimentation and time, alright if you have time on your hands, but it costs a lot to buy the software packages I curretly use 3 packages for imaging and 2 for vector work. My flying carpet backglass i created is awsome, but i would say that.

here is my flying carpet backglass image that i created.
