Anybody know what type of metal aggressive skaters use for sliding
on concrete? What are the properties that make it good for
"grinding".

I'm not planning to intentionally grind the concrete, but I'd like
some material that is durable and will slip on concrete. Conceivably
it can be disposable/replaceable if the replacement is not costly or
time-consuming. It is to be used as a short (about 1 inch) stopgap
between two skate wheels, so rocks and stuff (like a sharp angle
curb) cannot get in between and cause the second wheel to bind.

I'm considering using aluminum and coating it with super glue or
covering it with some material (to be recoated/recovered regularly).

Thanks.





I cant help you...but Im still chuckling 15 yrs after my kid came to
me and asked me to machine him replacement grinders for his skates.

I machined em out of Teflon. As I recall..he sprained his shoulder,
wrist, busted a couple fingers and whatnot before coming back to me
and asking for them to be machined out of something else.

So I made some from soft urathane.....chuckle....lol

My own skates have delrin grinders. Dont use em much anymore
though..at 54, I take too long to heal. So its easy skating now days.
