Arbor for mill advice

[Wongster]

I am reading the WR Smith's book on making a skeleton clock. In his book, he described a chuck that you apply super glue on to hole the clock wheels to cut teeth. The chuck has faced with shallow channels running around the centre on its face to allow air to interact with the super glue to bond the chuck to the wheel blank.

After cutting, apply heat to break the bond.
