Making some tree fertilizer tips from scratch.

[aametalmaster]

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

nice job, quick question what is a fertilizer tip?

[aametalmaster]

It screws onto a long wand with a trigger and a pump pushes fertilizer into the soil under trees giving them added nutrients. Sounds like a way to make more money. Tree fertilizing who would have thought...Bob

you think there may be a market for stainless ones ,
is this a popular thing that tree guys do

Stainless prob would be better, but they break and just wear out from the dirt. I never heard of it until a few weeks ago when he bought his rig

[hdwarner]

i was asking whether perhaps it was a viable production product
