How to attach a metal hook to a timing belt.

I use E6000 at work. It has a little more strength then "Super Glue", but not much more.

If you still like belts, what's stopping you from grooving the pulley to allow a fastener to pass through? All it takes is a lathe and a little patience. You shouldn't need the full width of the pulley to grip the belt if it is just lifting the weight of a frisbee.

Here is the link for the glue and thank you http://www.michaels.com/E-6000%C2%AE...efault,pd.html

that is true, however I want a system to be simple, easy to make and easy to repair if it breaks.

What isn't simple to make? If you have access to a lathe, simply chuck up a pulley and turn a groove. If you don't, a student can achieve the same results (although a little less pretty) with a file and some spare time.

What isn't simple to repair? You would effectively cut the teeth off the pulley in the center. So if you used a fastener with a .25 head on it, cut a quarter inch groove in the middle of the pulley teeth. The only thing that might fail would be a fastener and those are pretty easy to come by.

Oh by the way putting a fastener in the middle of a timing belt would increase the chances of of the belt breaking even if i were to make a groove in the middle of the pulley. The reason how I know is that I have tried. By having a belt you need tension and tension stretches to belt and when you stretch the belt with a hole in the middle of it increases the chances of it tearing.

[MrBasse]

A belt tearing is very dependent on the stress levels we are talking about. I'd hope hat there aren't a lot of forces involved in a frisbee conveyor, otherwise I would question the overall design.

An alternative to lathing a slot in the pulley would be to obtain a non-flanged pulley whose width is smaller than the belt width. You could then fasten the hooks to the edges of the belts. You would, however, have to consider how to keep the belt centered on that non-flanged pulley.
