I don't normally take the time to comment on anything. This design does buy its effective and usable quality demands I put my 2cents in. I'm not easy impressed at 69 years old but this really impressed me. It has everything needed but rubber feet to stop movement on a polished surface.
A little tip not related to the spool holder. If you need to lub plastic of any type use WPG (White Petroleum Gelly) if your looking for bulk buckets of 1Lb. If you don't mind the smell use Vaseline just a bit purer with the Metho added. Use very sparingly as a little goes a long way.
