Wood Shop Dust Collection
Our shop needs *real* dust collection. Here lies the start of plans to rectify that.
A whole room dust filter may also be in order.

Automating this stuff
No one will use it if it doesn't turn on automatically. It *must* be automatic. I've read that using less than 3" ducts with a large 15-16" blower is a problem.
I drew up some plans based on these resources:
This is a 2.5" duct, 'cause I originally planned to use the shop vac. The hole can just be enlarged to 3" w/o other changes. For 4" or 6" gates, the plates should be enlarged, and linkages will probably need lengthening. I made a lot of paper models to get the geometry right. Someone with experience modelling moving parts with CAD could probably do the scaling more quickly.
Machines that need collection
- Table saw (needs retrofit 6" pipe inside and out, maybe 5" and an overhead 3" collector)
- Mitre saw (needs a shroud built)
- Bandsaw (needs front plate of drive wheel replaced with something allowing for collection)
- Belt/disk sander (probably needs a shroud for the belt, or just a better sander)
- Planer (could probably use side shrouds)
- Stationary and pedestal grinders (hot metals)
- Grinder (cold metals)
- CNC mini mill.
- Wood lathe (needs a shroud)
- Drill presses
While all of these machines need dust/debris collection of some sort. Some of them may be better served by water buckets instead of a central dust vacuum. For instance grinders should have their exhausts feed into a bucket with water in it.
The dust collector should be on it's own circuit, switched on by a relay. Switches should be conveniently located near machines, or interlocked to certain machines.
