Custom Gauge Cluster V2.0
The first photo is the back side of the unit under construction. After a consult with my upholstery guy I decided to build the back side out more to give it a better finished look. Glad I got the consult with him!
This is the front side, I kept it at about 1/4" depth. The corners are a 2 1/2" PVC coupler I cut into sections and attached it with marine grade 2 part epoxy. This is the last build-up, when ready I will shape and finish it to my liking and it will go to my upholstery guy for finishing before I put the gauges in it. And regarding consults, many thanks to D-Daddy for helping me refine my vision of the finished gauge cluster.
