Timing Belts Anyone?

Smoke,

IMO, the Berg belts are an idea that looks good, but falls flat in
the execution. The pitch variation 'along' the belts can be
significant. (I've experienced this, and have heard similar from a
couple of others...) Fine for 'drive', not so good for 'timing'(due
to molding variations). The cost is often higher than other choices.

Timing belts of the HTD tooth style can be had with steel or kevlar
tension 'members'. And are available from multiple sources; a concern
for someone like yourself intending to manufacture a product.

Hope this helps.
