Perfect fit. I cut them just under the class 2A max pitch. Barely any slack at all on this commercial birdcage. Ordered more suppressor-mount brakes today, so fitting will have to wait.
Brad, when you get your mill, you can make a new spider support out of thick Al plate, bore it with the lathe chuck for a bearing, and make a spider hub. Or, since yout steady is larger, if you ever have the need to hold something irregular like an octagonal barrel, just make a cathead out of tubing and run it in the steady.
I must admit it's super nice to just let the barrel sit there and turn and not ever worry about oiling the steady fingers or the barrel walking out of the chuck.
