Welding Milling Cutter to shaft. How stupid of an idea is this??
I need to make a (1.5") radius cut inside of a pocket. This application would typically be handled by using a milling cutter on an arbor. After scooping up a handful of 3" dia cutters on ebay, i find out that the shank of the 1" arbor will shank out on the work peice about the same time I reach the radius surface (1" arbor may very narrowly clear it but the nut and spacers on the arbor def will not)
This project at some point in the future may justify buying custom tooling but it sure doesnt at this point (in fact already over budget on tooling)
So this is where the stupid idea comes in. What if I turn a 1" peice of 4140 down to 3/4" for a tool holder leaving a "hat" at the end that is 1" and TIG welding one of these cutters onto the shaft.
I have so many concerns mostly revolving around concentricity of the cutter in pretty much every axis.
Also slightly concerned about the heat affected zones after welding but i think on a 3"x.1875" cutter there will be enough meat to keep it from waffling terribly
Please tell me that there is a better solution to this problem
