Nice project. That thing really cranks out the chips! With the 735's really, really positive air flow and presure, you might be able to use a bag inside to make empthing out easier, and maybe neater. But that means you can't use it as a separator for air sucked through it. With that in mind, why not use a 44 gallon trash can. Adding the filter would be quite easy, a few bolts and a wood disk attached through the filter interior to the lid. You need some sort of seal and hold downs to minimize leakage in use. Give me simple anytime. Lots of good ideas in your project.
