I don’t have an elaborate dust collection system at my shop. My system is two shop vacuums that I got on Black Friday deals for about $40 each. I did splurge on a few extra hoses here and there but that’s it.
One thing that I always do is run filter bags in my vacuums. Especially while sanding the fine particles will quickly clog a filter and dramatically decrease performance. The filters also really suck (no pun intended) to clean. Filter bags do a great job of keeping your wet/dry vacuum performing at full capacity until the bag is packed full, but man they are expensive!
Filter Bags get Expensive, Y’all!
The best prices I’ve found for filter bags are on Amazon (which is not always the case). Here’s the link: http://amzn.to/2u5oCzU
These are 3 for $10 with free shipping, If you look sometimes you can find better but $3.33 per bag is about the best I can find. The Orange store runs about $5 per bag and the Blue store is a shocking $7 per bag. It pays to shop around!
If I’m building a Dog Kennel running my miter saw, table saw, and sander I can fill one of these up in a day, easy. So I decided to try and make my own dust separator.
My separator is about 80% effective. This means that every time I fill up the trash can I used I save at least $13. That adds up over the year.
What You’ll Need
Here’s what I used:
- Brute 32gallon Trash Can – I got this for free so I didn’t factor it into the cost.
- Scrap 3/4 inch plywood and some 2x blocks for the lid
- Gorilla Tape (The Bestest Duct Tape) to seal the lid
- Two 2in Sweep PVC 90s
- 2ft section of 2in PVC – you’ll see how I made this work below
- PVC Glue.
All together I spent about $20 in supplies. If you count the trash can then it would be about $50 total. Use what you have and be creative!
Form Fit PVC to Shop VAC hose with a Heat Gun
Now we run into a problem when we try to connect a 2″ vacuum hose to a 2″ PVC pipe. It doesn’t work… but we can make it work.
Use a heat gun to soften the PVC and then work it over the shop vac fitting. When it cools it will stay molded to the fitting giving a nice friction fit. (BTW I love my DeWalt Heat Gun)
See how I put it all together on Youtube
