1 1/2” boring bar used for boring a atv cylinder

[Alcap]

I wanted to try boring a cylinder knowing that it probably wouldn’t clean up the damage completely . The bore is about 2.650” and 4.5 + long . I had an old axle from a Power King tractor , learned the hard way it was case harden , I broke a tap off in a hole close to the edge . The holder is 4140 I found at the scrape yard . A “ V” was machined at the spindle center line so different size bars could be made to use the same holder . A 3/4” bolt and matching T slot made for the compound . The bolt was used to get the job done but since a shorter stud was installed

You’ll notice the bar has a flat milled on it , that was because the tool holder was only that tall and needed room to drill and tap for the clamping plate

nice work!
sure looks like it will not be deflecting, like smaller bars would!!!
