Crimping compression fit lug bars

[mountaineer]

Does anyone have tips on best way to “crimp” the tubes for compression fit lug bars?

When I put the bar in the tube and using tool to crimp. The indent is not tight enough. The bar slides through.

When I crimp without bar in the tube. It gets too tight and bar won’t slide through.

Thanks for your help.

crimp them with feelings so it just enough to stay tight inside

I've experienced the same frustration. Using a somewhat sharper tool with the bar in the tube as worked for me. I use a small channel lock, but I turn the tube at about a 45 degree angle to the teeth so they bite in a little more. Have to give it a pretty good squeeze.

I'm also interested in hearing what others do.

I have used a stake in the staking set and simply made a "ding" in middle of the tube. I fitted a wooden pin inside to prevent the tube from collapsing.

I am glad it I am not the only one with this issue. I felt stupid to even ask.

A wooden rod is a good idea. It will give just enough.

I forgot to mention that I used bamboo as it doesn't break easily. A thinner steel rod will do the same, you will obtain the needed friction.

You dont have to crimp a bar to hold in the tube just give the bar a SLIGHT bend in the middle.Easy, controlled, never moving
