I built a small dust/chip separator today. I combined an old 10 gallon shop vac with a Home Depot bucket. Again, I looked at many Youtube videos and put this unit together. I still need to add some silicone to where the bucket fits into the the hole I cut out in the clamping top of the shop vac and around the inlet tube. I did at test run on it to see if it was even going to work. Did a good job but didn't have the shop vac perfectly clean before I sucked up some debris. When I check the shop vac after pulling saw dust and chips out of my other Vac, I did find more dust on the bottom than I though I would. I took a lot of photos of the build today but won't put you all to sleep by posting them all! If you are interested I'll try linking my Shutterfly account.
If you are familiar with the Thien-Baffle disk and have any ideas about fine tuning it, I would love to hear from you.
