Your dust foot looks really nice. Thanks for sharing.
Does the foot come apart at the PVC fitting or does it come out of the MDF foot?The foot pops right off to facilitate bit change and zero set and then simply slips back on.
I have a prototype I am working on for my Shopbot PRT. I have the lower dust shoe about finished and have ordered the brush material. My goal is to make the dust shoe as small as possible and not interfere with the cutting bit. I think this will create better suction and allow you to get closer to the edge of the table without loosing suction. Once I have the concept proved, I will make it look nice. I have ordered different lengths of brushes so that I can experiment for maximum efficiency. I think being able to switch to different length brushes would be a definite PLUS.
