Topic tags/keywords: blast gates

I’m about to move into my newly constructed shop and need some advice.

My cyclone dust collection system will be located in the “crawl” space below the shop thus the ducts will come to most machines from holes cut in the shop floor. I plan to have separate gates for each tool to improve efficiency of the system.

Aside from being lazy, I’m a bit on the older side of young and don’t want to bend over to the floor to open/close the blast gate every time I start or finish working on a machine. My plan is to run rigid duct to the gate (more or less at floor level depending on the machine) and then a short piece of flex to the machine (again for efficiency). In my current shop with overhead ducts I use a pair of strings to pull the gate open or closed from the front of my table saw thereby being efficient for me and keeping the gate near the dust outlet thus the length of flex hose to a minimum. A bit goofy but it works. I’m hoping for a more refined solution.

Does anyone have ideas as to actuating arms, levers, pullies, or whatever? Thanks!

What about running some thin steel cable through small diameter pvc? Similar to a throttle cable on a car. You could put all the bends you need in the pvc and attach one end of the cable to the blast gate and the other end to a small pull knob.

I did one for my UniSaw, it’s foot operated and works well.

The whole project is detailed here

- Current thought is to have the gates near the floor; BUT that’s just the current thought waiting on a better idea.
- Curt: thanks, looks great as do the other pix.
- I’ll also have individual gates (and therefore need actuating arms and attachment points) for a lathe, band saw, planer, jointer, sanding station, chop saw, and router table. It may require taking Curt’s idea and modifying for the unique geometry of the specific tool.
- thanks to all for these and future ideas.
- I’ll post pix of what I end up doing.

Have your say...
