Dust extraction for Emco Star by Andre Asselbergs

This is a set of  dust extraction parts for the Emco Star. I have been sent the files by its creator, Andre Asselbergs in order to share them on Printables. Andre's original post is below.
 

I’ve seen a few posts here about dust extraction and being an Emco Star user since 1975, it’s fair to say that I’ve tried just about everything.

First let me say that I have homogenised a system of bayonet/socket attachments with pool filter pipes and a standard shop vac. It allows me to attach a range of machines to different locations in the system. The first picture shows one of the connections (Mitre saw). I have a wide range of these that connect to many hand tools (skilsaw, sanders, hand plane, routers, etc.)

The second picture shows the connection to the Emco table saw with two different attempts. The 1st was a pre-bayonet fitting attached to the slot at the bottom of the blade guard. This worked fairly well but a still had a lot of sawdust blowing around. The 2nd try was taking vacuum directly off the saw blade (bayonet connection). I get about 80% of the cuttings using the 2nd connection and the bottom slot closed up with masking tape.

Third picture is taking dust off the bottom of the bandsaw blade. Not a great solution because there are too many places in the housing where vacuum is lost. Only about 50% effective. The fitting here is a little different to the others because of closer proximity to the blade, has a smaller bayonet.

Fourth picture is a chute on the planer to remove thicknesser shavings. It works quite well when machining narrower timber but when a wide plank is sent through, the cuttings are too “wide” for the suction line and they quickly back up and clog. As the last picture shows, even tapering the pathway doesn’t help much. Same bayonet connection.

I have a similar catcher that fits in the thicknesser slot (table wound right down) for when I’m using the top planer. It works much better because I seldom send wide planks over the plane and smaller cuttings (from an edge) are gathered easier, about 70% effective.

I’ve also designed a cover for the disc sander to be 3D printed but to be honest, I’m too stingy to commit 120grams of plastic to print one. I’d rather put up with the dust which is not huge. Like the belt sander, seldom used.

I guess if your dust extractor uses a 100m pipe, these systems would work better but the Emco is a small machine that doesn’t p,at nice with big pipes. But I’m not that stressed by not having 100% dust collection, not ready to spend $000s on it.
