Problem with Edge/Enve compression plug.
I am building up my Lynskey and went to tighten the compression plug. The resistance gets very tight on the bolt and the entire plug spins. The bolt is tight and won't tighten up. It is not even gripping the steerer tube yet.
Anyone have any suggestions?
The only way I am able to get it to get bigger is to remove it and hold it expandable plug and wrench the bolt. It is way to difficult to expand.

Does you fork have a carbon steerer? Steel steerers have thinner walls and require a larger diameter expander to work. If it is a carbon steerer than I don't know why your expander won't work unless the bolt's threads are damaged.
You can buy an FSA expander relatively cheaply and these do work well if you can't fix yours.

Hold it in your hand and turn the bolt to expand it. See if you can expand it to where it's too big for the fork. If not, it's too small, either because your fork has thinner walls than it's designed for, or because it;s for a 1" fork and you have a 1-1/8" fork.
If you can expand it bigger than the fork, take it apart and grease the threads, then reassemble it and expand it to where it's just big enough that there's a bit of resistance as you push it in. Then friction should hold the collar while you turn the bolt to lock it in place. If it still slips, paint the collar with rubber cement, let it dry and try again.

It is the right size. Holding it in my hand I can get it the size I need but can't in the steerer. I will try your suggestions and give it another shot
Compared to the FSA ones I have used in the past this design is stupid.
I'll try it again.

You do know that you have two bolts to tighten - right? With the cap off, you use a 5 or 6mm hex key and tighten the interior bolt - which expands against the sides of the steerer tube. Then insert the cap screw through the cap and into the interior bolt to pre-load bearings.
It fooled me too - and I had to call Enve. Once I figured it out - it actually seems like a nice design.
