The right key is a joyful possession

Tuesday, November 27, 2012

I'm restoring a fifty year old "Clausing Drill Press" wirh a "Jacobs Drill Chuck" that is no longer in production. The chuck key was missing so, I found what looked like the right key at : DrillSpot.com and ordered it. It was dilivered quickly (free shipping) and was well packaged. Best of all, It fit perfectly I've rebuilt the chuck and I'm still working on the drill press. DrillSpot has made me "A Happy Camper"

It is very well made and fits like it should

How can you improve on perfection.
