I have been a Machinist for over 25 years. My Boys have place 1st or second with their own car designs and my axles. I let them build there own cars all I do is cut them out, add weight and tune the rail rider after they sand, paint and assemble. My person cars have won every Akela race last 3 years.
I can customize your axels to any specifications you desire. I also have polished axles not bent just tried up and straight. I will be adding more different sets as I go.
