My NEW Unique Blast Gates

[Bob Slater]

Nice system. Just curious, how are you supposed to ground plastic pipe?

[Michael Kowalczyk]

Thanks everybody.

Don't worry, Michael, the grounding is the next step. Thanks!

I'm not worried just want to make sure you have EYESWIDE open.
Here is a link that goes into more detail...

Some claim to never have had a problem, others have. IMHO, Is it worth the chance?

This is what I have on my CNC's. It is great to be able to unclamp anywhere when you need to reconfigure or clean out the cartridge filters behind the Cyclone.

I really liked this design and did some Sketching Up to see if I understand it fully.

Just for fun, I tried to lay out the pictures just like in the original post. Thanks for sharing your design with us Jameel.

What kind of gasket material did you use. Is it a smooth plastic or a felt?

That is a very good question! I have read opinions to run a wire either inside or outside of the pipe. I have also read where either is ineffective. As I understand static accumulation on noncoductive surfaces, one solution is to make the surfaces of the nonconductor conductive. This could be done with metalized paint, carbon impregnated paint, or conductive solutions. Conductive solutions are stuff like fabric softener or spray static guard.

I picked up a tip on another forum about using copper foil tape

There are cheaper alternatives but I'm not sure there are easier ones.

Nice Sketchups John. I used CNC spoilboard gasketing material from All Star Adhesives. It's 1/16" thick, medium density. I bought it by the foot. It cost me about $40 for 6 gates. Not exactly cheap, but my gates are air tight.

Mythbusters tried this & it didn't work.

Hi Jameel,

Don't know if you are still "out there", but I was wondering how those unique blast gates are working out? Any problems with clogging? Has anybody else implemented this design and what were the results?

thanks!

Still use them about every day and they still work and seal like the day I installed them. Very satisfied. Hank Knight just finished an install with them, and incorporated some micro-switches to turn the DC on/off. Don't have a link handy. You can search for them here I think. He may have also posted about them at the Woodnet forum.
