I have the proper puller, they are being stubborn. I've pulled numerous crank arms, but these are not wanting to move.

If they are like mine, they take a standard Campagnolo or Park puller, but do make sure the puller is pushing against only the spindle and not any part of the crank.

The problem is exactly that, the "shoe" of the tool is pushing on the crank arm, not the BB spindle. I'll figure a jury rig from there I hope....
Thank you.
Thank you.

No idea, but points for using "recalcitrant" in a thread heading ...

A couple of days ago I was pulling some crank arms and one game off OK but the other one would not budge. After 10 minutes I looked and and to my surprise there was a washers in the crank. Some one had installed two washers and I missed the second one.

It may be obvious but I would check to make sure there is no washer still in the crank. I've seen guys break cranks and tools because of this scenario more than once.

There were two answers to the question. First I used a plug to space the shoe of the tool off of the crank arm. Bad idea as now the little plug is stuck in the spindle-I'll get it out, just not sure how yet.
The real answer was to take the shoe off. It didn't want to come off at first and I didn't want to force it. Then between attempts, it came right off.
I have an aversion to excess force, having destroyed many things in my younger days. Which is also why I am confident I can remove the plug from the spindle....

To the suggestions already offered, I'll add chuck wedges, perhaps to be used in conjunction with the Park tool.

Yep, definitely ruined it for anything but this set-up. The "shoe" that is now unscrewed, won't screw back in. Live and learn (and spend money).
