Interesting :?.
1) It's painted grey - not black;
2) It's been broken and repaired through the main casting (the weakness I mentioned) - so the grey paint is not the original (though that's not to say it wasn't originally grey as well);
3) It has a four spoke flywheel - not five spoke;
4) The flywheel has a flat rim (presumably to allow flat belt drive), while yours has the more traditional hand-friendly roundish rim.
With regard to the column/pillar and foot: I'm going to post the info in my thread - https://www.woodworkforums.com/f163/p...-61-a-177652/3 - as the dimensions are specific to a Canadian Blower & Forge No.61, and there may be minor differences to a Buffalo Forge No.61.
Cheers, Vann.
Edit:
- In the other thread you'll see the length of the column is 14 1/16". However, if you're planning to use the drill with a Jacobs chuck, you'll loose ~2 1/2" of height to the new chuck, so I suggest a 16 1/2" long column (or longer).
- The centre of the round portion on the CB&F foot is 1 7/16" from the mounting board. However, best to check to distance from the board to the column centre at the other end of the column - the base of your main casting, to ensure the column is parallel to the backing board.
