I'm going to have a wood worker friend make a top shelf for me. Does 
anybody happen to know the standard 145  dimension from the top to 
the upper surface of the shelf?

I saw Speakeasy was selling what they called "space age polymer" 
belts on eBay that did away with the tensioner pulley, which I don't 
have, so that appealed to me. Is it just as well to run a real belt 
with adjustment slots for the motor and no tensioner?

Compared to my 860, this Franken-Leslie should have tons of bass no 
matter what I end up with. Right now there are two angle cut ports in 
the woofer shelf that I may experiment with reducing if the bass sounds weak.

Thanks for all the tips so far. It's been very helpful.
