i just finished riding mine all day prety much and it held up good i did have to tighten it again a few times but i also was only using one bolt and noting to keep it form ratteling like a tyer tube
Thats wht Im probably gonna try next. My school used to have a metal working class, but now they dont. So all the scrap metal is in my engineering room now. I used to be in the metal working 2 years ago and we always worked with these flat rectangular pieces of steel that would be perfect, and theyre just laying around now.
I just broke this a few days ago. I knew it was gonna break since its such soft aluminum like you guys said, but it was actually a pretty good temporary brake.
