Well I finished up a good chunk of a VR pinball cabinet project over the past couple of weeks. The cabinet itself was professionally made by Greg Butcher who makes professional grade pinball and arcade cabinets here in Michigan. I ended up priming, painting (a metallic blue) and clear coating the cabinet to try and give it a nice finished look. I still need to wire everything up inside the cabinet and plan to add side rails to the cabinet after I replace a set on a real pin. Most of the new parts I ordered are going on one of my real pinball machines while the older parts are on the VR cabinet.
In no way to do I think VR pinball will ever replace real mechanical pinball, not a chance. I wanted to build a VR pinball cabinet as I think playing pinball in VR is now the best simulated pinball experience, oh and yeah because I'll never be able to afford (or house) dozens of real pins, lol. The tables offered in Pinball FX 2 play extremely well in VR and being able to replicate the feel of a real pinball machine with those tables creates a pretty realistic playing experience.
I added some additional buttons to the cabinet so that it can also be used as MAME controller and hopefully for some VR MAME games once they are out.
Wiring / hardware information came from the Tested.com article below and the link to the buttons I used on the cabinet (recommended by Greg) are below that.
