I started by facing both ends of this 4.75” diameter by 4.375” long aluminum bar. That went well.
The I drilled a hole using progressively larger bits ending with a 1.125” hole. That went ok.
Then I tried to part it in half. Things started degrading quick from here. I broke multiple parting blades and ended up cutting it with the bandsaw and re facing the cut ends.
I need a 3.5” hole in the center. I bought a .75” boring bar in hopes to bore the hole to size. Is this dumb? Is the a better way to make the hole bigger.
Advice from the professionals on here would be much appreciated!
