Greeting Gentlemen!
I thought I would chime in to clear things up. Those other parts that are white metal are not my product. ZM is using MDC to do their outsource casting. They must have forgotten to update the label. I did initially work on the CAD for the undercarriage and tires on the 219. The initial run of castings were made by me.
James, I'm sorry to hear about your dissatisfaction of the JU-88 gear set. Please PM me a photo of the set with the defects and I will make sure that you get a perfect set of castings. Matt is correct, they are a pain to demold. They were mastered by Alan Troi from Austria that is also here on the forums.
I've had a lot happen to me in the past 2 years mainly due to taking care of my ill mother and her recent passing. I will be producing things at a higher rate starting next month. Many of my new patterns will be CAD designed and 3D printed on my 5 micron capable machine.
