Remember that's waste and vent material, not meant for heat . You got the shop , and nice work on the cut . You can come close to the same thing in wood using a table saw , it's a neat trick and old timer showed me .
Off topic , but I have to ask ,,, do you have your PVC dust collection duct grounded ? Static spark can cause the dust to ignite .
Actually these big fittings are Schedual 40, not drainage pipe fittings. Going to do a pre-trial today to try out the paddle.
If it turns out hilarious, I'll post it for a good laugh. :D;)
Actually, the controversy continues about that. A Grain Elevator is hugely different than us small shop owners. We do not have, nor ever will have the volume of material transfer that has blown Grain Elevators apart.
Also, it is not possible to ground an insulator. PVC is non-conductive. It even gets used for that, IE: Electric Fence insulators come to mind.
I can appreciate the concerns though. Thank You.
In real life experience, when my system was new and in development, it use to generate enormous fields of static electricity. It would charge up the whole house and we'd get nailed left and right. Quite irritating!
Then, after about 4 to 8 weeks it got less, and less until it almost doesn't generate the field it did. Why?
The ducting is covered with a very fine light film of static clinging dust from the materials that passed through on the way to the cyclone separator. (Which is steel, and dumps into a closed 55 gallon steel drum through an 8" drop tube.)
Most of the main runs are 6", with 4" branch connections.
But the point being, there is almost nill static electricity generated in a seasoned dust collection system.
Mine is unique in that I have a 2 HP cyclonic separator, with a 1.5 HP booster blower under my center equipment area.
A lesson taken from the big boys where booster blowers are common in collection systems.
One of my pet peeves is a shop with 6" of sawdust everywhere. :mad: So my shop has outstanding dust control.
And also, outstanding noise abatement. The cyclonic separator is boxed in with sound board lining to quiet it down. After it filters the air down to .5 microns, the air goes over to my 7 HP air compressor closet and circulates the cleaned air down over the vertical 80 gallon air compressor and exits near the floor. That enclosure is also lined with sound board and baffles to deaden the inherent noise.
I can't do much about blade or bit noise, but I'm hell on the noise I can control. ;)
Lastly, and more importantly, the last I studied up on it, there was not a single incidence of a home shop dust collection explosion. Period.
But the paranoia continues. :rolleyes:
