Cut strips out of your favorite beverage can about 1 inch wide. Narrow enough so that they won't be seen, but wide enough to give you some grip. The circumference of a beer can allows you to wrap the bars about twice with some left over. If you want to its OK to secure the strips with a little tape to hold them in place. Depending on how worn your risers are you may need to do this more than once. My brass ones are pretty sloppy and I think I have three layers of strips. Whenever you have enough in there, tighten up the bolts and the riser will compress the aluminum. It's been working for me for a long time that way. You can use aluminum flashing if you want, but a beer can is cheaper. BTW, cranking on the bots if there is not enough contact isn't going to tighten anything up. Better to build up the surface with shims and not risk breaking a bolt. More is better than less.

 

thanks man, if she slips again i will do it

 

The beer can shim trick is: cutting a few strips of aluminum can and tightening em between the bar and risers. The aliminum is pliable enough to smash down between them, and gives resistance against the steel of the bar and riser. I don't know why aluminum resists slipping against other metal, but it does.

 

yeah I know all about that kinda "customization". I used to mess with old VWs, my old split window bus was held together by everything from bailing wire to street signs.

p.s. ... looks like we were both replying to the beer can shim question at the same time. I have to say, you did a better job though. LOL

 

We need to keep passing the knowledge along to the new generations. Next week's lessons are brazing with coat hangers, creative uses for JB Weld and what to do when you lose you master link clip.

 

if you mark your riser locations vise-grips make pretty good knurls.
