Face plate design was arranged last week and roughly designed at the beginning of the project. The plastic for the face plate had been cut long ago but no holes had been cut. Finally, the parts were gathered and everything was cut. Many of the parts were able to be mounted immediately but the graphic equalizer needed small bolts for standoffs. The graphic equalizer didn’t get a clean mounting configuration because it has a button which may need to be accessed at startup. Adding a clear window on top of the faceplate would also be a huge amount of work and ultimately turn out to be inconvenient.
The panel meters were the most difficult to mount. They required a large hole with no obvious center reference. They also required two mounting holes to the side of the hole. A hole saw was used to cut the large circle and the small mounting holes were measured by pressing them onto a piece of soft wood where they left and impression. Those impressions were drilled and aligned onto the faceplate.
Arcade button mounting was not a new experience but that project came way before this blog. I built a MAME arcade years ago. Arcade buttons have been marvelously durable and simple. Most often, I choose the classic concave button style with a long post and a replaceable microswitch at the bottom. This one was available at the local surplus store and flashier than previous uses.
