Below are a few videos demonstrating how I build my arcades with various techniques. The videos are great reference but usually go beyond a 'vanilla' assembly. The pdf manual is the most accurate and up-to-date assembly guide and is the reccomended reference when building any of my arcade kits.
Here are other mini arcade and arcade builds that you can reference. There are similarities between many of these designs not just in mechanical assembly but also electrically. Each video does something a bit different. If you have an unanswered question, need to see something again but in a different example, or want to explore alternate ways to build your arcade, give these videos a watch.
