Hi Kit

I guess you are referring to the Everman Belt system.
An interesting design Idea, Patented.

Keeping the join between the belts clean is important. Wood chips will have to be kept out.

It is also worth noting that timing belts do not like bending backwards over a tight radius. The reason I used a pair of largish ball bearings. I cant remember the exact size! Maybe 60mm. We used steel cored European belting Breco? Not no name Asian, You can look up the minimum bending specs on their website.
