Our Class A3 and A4 in O gauge are a pair of complex projects - each locomotive having many details which are fairly unique to the class. This has presented us with several challenges during the CAD development stages and meant it has taken slightly longer than planned to get to the tooling stage. Both models are now in the tool room, metal is being cut and shaped and in the process of being completed. On such complex and large models this will take a while and we have outlined some updated dates for the project.
1st Samples - Mid March 2018
2nd Samples - Early July 2018
Decorated samples - Early August 2018
Production Samples - Mid September 2018
Delivery - Mid February 2019
Following comments made about other O gauge items with gear problems, we have discussed the use of differing materials for the main drive gears
The material choice will affect multiple factors and the best decision will be made by testing different solutions. The motor has been designed to have less stress on the gears due to its orientation in the drive train. We will also be testing different materials for the gears - both delrin and brass. Both have pros and cons but we will be open with our results and let you see which was chosen and the metrics we have used to test them.
If you have any questions or comments then please, either post them here, or contact us on firstname.lastname@example.org and we will be happy to hear them.
