I have some custom made feed dogs that will fit a Juki Lu 1508 NH. The feed dogs were made with out teeth and will not mark up your finished leather as the factory feed dog does. I have uploaded a picture of the smooth Dog next to the factory Dog for comparison. I'm pretty sure this feed dog will fit other 1508 machines besides the NH. I will except returns if you want to try one out. $30 + shipping Email- info@PirateUpholstery.com
