My current project is replicating the Maximall Fuel Gauge for the Fokker DVII.

I was loaned an original to work from and after dissembling, measuring I drew it up in CAD. This way I can double check my measurements, clearances, etc. This also helps me decide the best ways to manufacture the parts and create fixtures.

Instead of subcontracting the patterns for the castings I decided to give it a try. The head pattern maker at the local foundry was very helpful, and patient with me.

For my first time I think the results are pretty good.
