Started work on the filters

There is a pair of filters that need to be combined into one assembly for the cyclone dust collection system. I started on that last night. The two filters are identical but in order to connect them, the foam weatherstrip needed to be removed from the top of one (on the left). This was done with a razor blade and rubbing with "Goo Gone".


Then one filter was inverted and placed on top of the other.


They need to be bolted together, but the manufacturer does not supply bolt holes. So I drilled 8 holes through the metal flanges. I didn't have the bolts so a trip needs to be made to the hardware store.


The assembly will be elevated and connected to the exhaust port that it is sitting under in the second picture. In order to elevate it, a "cleanout" box needs to be built for the bottom. The height of this box will be the amount of gap seen in picture 2. The box will close off the bottom so that exhausted air MUST be pushed through the filters. However when the DC is turned off, some of that fine dust drops down, so the box needs to have a cleanout mechanism. Not exactly sure at this point how I will do that, but I have two ideas.
