2019 POTD Thread Archive

POTD has been waaay too long in the works. I had a primarily wood shop in the basement of my old house before my wife and I married 28 years ago. My Grizzly 4-bag dust collector did a great job keeping debris just in the basement. It has a 3 HP motor and moves something like 2000 CFM. For comparison, a typical 2 HP shop vac moves about 250 CFM.

We bought 64-acres and built our current house a year after getting married. I finally got around to hooking up the dust collection system again. I had used just a single hose to the table saw on occasion and thickness planer, but the sander, band saw and router weren't hooked up.

I used 4" drain PVC and 4" flex hose from Grizzly for the plumbing. It's not shown, but there's a copper wire running through the PVC which goes to ground for static electricity. Don't know if it's just an urban legend or not, but supposedly the dust can spark and explode from the static electricity built up on the plastic tubing. I ran a lot of wood through my planer and table saw without static electricity protection back in the day; have never witnessed or read a true account of a fire, but figured it was easy enough to run the wire as a precaution.

The blast gates were shop-made 35 years ago. Used 3/4" thick hard maple, 1/8" masonite and a 4" drain union cut in half. Used construction adhesive to hold it all together, but beefed them up with some screws before hanging them on the wall.

Thanks for looking.

Grizzly 3 HP dust collector in the far corner. Use a Grizzly "Long Ranger" remote switchable 220V plug to turn the system on/off.

The flex hoses are hung on the wall when not in use. My only concern is the dust from the far end might fall down the "Y's" as it travels to the collector. Might have to turn them 90 deg. so the junctions are flat to the world. I did plane 100 board feet of black walnut using the far-end port and had very minimal chip dropage into the sander and band saw runs, so probably OK.

Shop-made blast gate. They were around $20 each back in the day. Wouldn't even consider making them now as they are available for around $5 each.

Very nice looking, Radials. Should it have a way to mount on the T slot???

I've been needing a decent oil cup and made this one today from some loose pieces of scrap. The body is 2" diameter .120 wall tubing and the top/ bottom are 3/8" thick x 1-3/4 diameter slugs.

Nice work.

To make it better put a magnet on the bottom. Press in the bottom cap a quarter inch to acomodate the magnet so it will stay where you put it on your mill..

If the magnet sticks out the cup will sit on that and it is not as stable as it could be. If the magnet is glued in and sets off the surface with the cup sitting on the surface the magnet force will be much less.

To get the magnet glued best be sure the magnet can get in below the bottom (Won't stick out). Put some glue in, epoxy or whatever works then the magnet. Now the important part. Turn the cup over on a metal surface with the magnet in and glue not dry but put it on some wax paper to dry. The wax paper will pull off easily after it is dry. What that does is let the magnet go right to the bottom of the can with maximum direct contact and the cup also maximum contact.

If the bottom cup won't move you could still put it in your lathe and carefully bore out a place to put a rare earth magnet. Like one the size of a nickel. And mount it with same method as above.

Thank you Robert. That's not a bad idea but I'm actually making some table covers as well right now to keep the chips out of the T-slots on the table. This one actually just ended up being the prototype as there are few things I want to to differently and begun making the second version already.

What is it made from? Milled from Copper then sand blasted? Metal 3D printed?
To me, it looked like a 3D print that was then cast, so there are three ways to get the finish. My curiosity is there, too, as to how he made them.
