I just posted a YouTube video of my ERWIN PRODUCTS VERSION C DUST COLLECTOR using a standard 16 gallon Craftsman shop vac which surprised even myself with almost total dust collection. The version C unit features a new quick release extension which can be removed and re-installed in seconds with no tools or loose hardware, just two snap latches. The version C extension has also been redesigned to obtain optimum suction very close to the cutter. Although the shop vac results were excellent I would still recommend a 1 1/2 hp or larger dust collector as they are designed for continuous operation and are much quieter and will do an even better job.
Also, I am strongly considering getting a table at the Houston show to present my dust collector. I am dedicated in making my ERWIN PRODUCTS DUST COLLECTOR the best available for the CarveWright and Compucarve machines.
