The pillar on my drill is 2.3/4" OD. I suspect the museum where I do some volunteering could find me a scrap rod by Gardner or Mirlees to accommodate that, but I suspect it would be at least 18" long :)

Nice project and great write up as usual.
I made a stand alone tapping guide years ago. I must say your casting looks better than mine.
I picked up a set of long tap wrenches at Grizzly. http://www.grizzly.com/products/Extra-Long-Tap-Handle-Set/H2721
The current price is about the same but mine was a set of 3. I used the smallest one in my tapping arm. Even it would be too big for a design like yours but it works great in a bigger arm.

No snow in Calgary yet.

Cheers

John so from what I see on the news this morning I think we can agree that Mother Nature has decided to be a hag :confused:
