Well some good news on the airco; a fan will be shipped to me and hopefully I have the unit back on work before this weekend because there weatherforecast is giving tropical temperatures for saturday and Sunday...
I just checked the Red Widow and I can feel that the oil is not completely cured. But I guess that's ok because it is better to wait now and continue with the next coats around beginning of next week.
Perhaps I can start with the design of my own trusrod cover and print it on my 3D printer.
