US Burke #4 - Vertical head bearing update and new ideas

**Update** Repurposing the 1 1/8th inch arbor for use to run annular cutters won’t work. I love the concept but there are absolutely zero options to purchase cutters with a 1 1/8” inner diameter. Next step is buying a lathe to make a #9 tapered arbor shaft. It’ll take time to teach myself the new skills but this passion for restoration and machining is growing and I look forward to the challenge.
