Looks like some folks (@claytonisbob, @tgm022861, maybe others?) experimented with using a glued/adhered ‘fixed belt’ for the tensioned belt to be meshed with. Goal being to reduce effect of belt slack, especially for longer belt runs. No idea what difference this’ll make to performance? Was considering positioning belt teeth facing/oriented same as today, somehow housing/protecting using cheap shallow L or C channel profiles available from big box store, but honestly haven’t spent much time thinking through this one.
