Looking for comments on the current woodshop dust collection system. I’m thinking about proposing a vote to allocate ~$1000 to get it working correctly. I think we’ll spend about half that, but tool attachments can get tricky, and there are some unknowns with the current system.
The first thing that needs to happen is that Greg and I will be deciding on a more permanent layout for the tools. This will be happening sometime after the medium CNC and Coy’s plywood rack are removed from the woodshop.
After that I’d like to improve the dust collection system
Currently we have the following:
- Table Saw attached to mini Cyclone + shop vac
- Drum Sander on flexitube
- Radial Arm Saw (should be done tomorrow/soonish)
- CNC table
- Band Saw
Things I’d like to hook up:
- Jointer - Might just end up with a better box
- Thickness Planer
- Spindle Sander
- Router Table
Nice to have:
- Second cyclone for portal hand tools, like the orbital sander, attached to a dedicated shop vac as a unit. This could be a bucket head design.
- Dedicated shop vac for table saw dust collection
- Dust collection for Drill Press/Lathe
Problems with the current system:
a) I’d like to build two boxes, one for each output, both with see through sides, so that people would know when it was time to empty them. Further the large dust collection would be more efficient space wise as a flat box, up against the central pillar. I’d like both boxes to be designed such that they could be easily disconnected and dumped into the trash bin. Running the shop vacs into ports appears to have cause problems with the small dust collection.
b) I’d like to build a manometer to determine if we’re getting enough air flow through. I’ve got parts for this partially from Steve Jones. Current plan is to have a light turn on when there are problems.
Too much flexitube - Flexitube is less efficient than metal duct work, resulting in poor performance.
a) Band Saw - Could probably be mostly redone in metal tubing. Route is a bit wonky. Also needs a different splitter, current top hose has little suction
b) CNC Router - Could probably have it’s flexitube shortened a few feet, not a big deal. Also needs to have the split going to the 2nd CNC removed.
c) Large saggy flex tube feed into the small dust collector - should be mostly replaced with metal ducting.
d) Similar problem with the large dust collection
Currently we’re getting a lot of dust only on the small dust side, indicating an overall problem with dust collection. Not sure why this is happening. This is worrisome, because it could indicate that we need to replace the filters, and that there’s a serious problem with the current cyclone.
I know there’s been some talk about adding in neat features like automatic start, and the like. I’d like to have the system working first, connected to all the tools, before we start adding geez whizz features. So any money for this would be only to get dust collection flowing from our tools into the system when it’s turned on manually.
So I’d like to open it up to the Hive, and see what the current thinking is. Are there things I’ve missed or left out?
