Modify a onestage Harbor Freight 2HP dust collector to a twostage with a Thien baffle. Key takeaways:
You don't have to pick up the motor while you measure.
You don't have to spend a lot of money (unless you upgrade to a better filter).
You don't have to rebuild the dolly.

I also post pictures of things I build on Instagram:   / thesnekkershow  .

You can buy Wynn filters at https://wynnenv.com/woodworkingfilters/.
The current (2021) model number for the filter I put in my system is 35C222NANO. They also make a 35B222NANO, which is the same thing but with a removable top cap.
