Low Cost DC blast gates

Hi Div, you are an asset to yourself. Night owls again.

-- When you know better you do better.

You have a feature that I wish my store bought gates have. That is a slot to push dust out. I happened to buy the type where I have to clean out the groove to get the gate to close all the way. Nice project!

Hi Div. That’s a fine idea. It’s one of those things that many would say ‘why didn’t I think about that?’ But you actually did. I also like to make stuff because it’s hard to find many things where I live too. Well done.

Looks great. How is the hose connected? It appears from the picture, the hose is connected to a female connection. How is it fastened? Thanks for sharing.

Although your design is good, I have suggestion to improve it. Your stop bolt does not allow the gate to open fully which restricts air flow. Make the frame rectangular, and the notch the 4” circular cut out. The gate will fully open and yet still have stop to prevent it from coming out.

Not only did you come up with a great idea, yours will probably still be at work when the cheap plastic things are in the landfills. Rand

Chuck Anstrom, I have a female PVC connection on the machine side. This fitting comes standard with an internal rubber flange, meant for a push on watertight fit onto standard 4” PVC Pipe. The hose I use is a tight fit into this as well. There are many ways to skin this cat!
I have stretched and formed PVC pipe by carefully heating with blow torch. Keep flame far enough away so you don’t scorch and rotate pipe all the time untill soft.

PCM, very thoughtful input, especially if airflow is minimal. My DC system sucks like a hurricane, so I’m not too worried. Will definitely add your suggestion when I make more. Thanks for the idea.

Hi Div ek is bly ons het ouens met goeie idees. Dit inelk geval atlyd beter en goedkoper is die gekoopte goed.

Good work. I’m about to start hardlining my DC in the shop. These are a great idea. Even with woodcraft and other retailers the
