 Making some tree fertilizer tips from scratch.
For my neighbor and his tree company. I started with some 4140 steel and turned them to size. Then i drilled the spray holes while still mounted in my lathe with my cross slide hole driller then turned the taper with my home made taper attachment then finally the sharp pont with a disc sander. Don't need to be pretty since they just go in the dirt...Bob
