Modify a one-stage Harbor Freight 2HP dust collector to a two-stage 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.
- You don't have to build a new dolly.

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