Just a idea.
Working on my slinky dog and want to use screws to hold it to the base.
Took the wheels of the dogs feet by using a xacto knife and sliding off both plastic axles on the wheel, then pulling the wheel of and slicing off a little tab that is also on the bottom of the foot. Going to fill the void up completely with JBWeld. Once this is cured will drill a hole and tap it for a 4-40 or 2-56 screw. Then I will counter sink the plastic base to accept a flat head screw. Should work, just did not want to glue the feet down to the plastic base. Anybody else have any other ideas?
