Tungston grinder Welding

originally made one with several holes to put electrodes thru but had to clean holes out after print with drill and didn't work well.    This design you will need to make an aluminum bushing fit to match the hole.  Ultimately I this serves its purpose but I don't like to use it because of vibration.   Maybe someone take it and run with it? 

Just install on the shield with some pop rivets.
