Belts are a nightmare to source, great if you know the exact one but try and find that size. The cost is usually more than the boomer is worth and you don't even know if that will fix it. What if your belts aren't listed anyware and have turned to black sticky licorice? Fear no more use some high quality super glue and make custom sizes to suit. With older decks you must get the balence correct between tension and purchase. If your belt is too tight it may slow the transport speed. If the belt is too loose the auto stop may not work. This can then be used to order the exact size belt. Or just keep using your custom one!
