Chop saw hood, make or buy

[Alan m]

i was thinking of getting a chopsaw hood for behind my dewalt 12" scms. i want it because the extraction is crap and need to use it inside in finished houses.
i will be using my ct 22 aswell.

i was thinking of making one , if anybody has done this have you any advice. do any of you think that making one is worth it or should i buy one of the FastCap Chopshop Saw Hoods .

is there anywhere in the uk or ireland that sells these or similar.

unfortunitly i cant find 1600 euros lying around to upgrade

 

[Ken Nagrod]

I like the Fast Cap model.

 

[Alan m]

how hard is it to break. will it beand and rip easily

 

[Ken Nagrod]

No, it won't break, tear or bend under normal use.  If you're handing it off to a crew to work with and you don't trust them, get a new crew  [big grin].  Just don't abuse it and you shouldn't have a problem, however, if you do, Paul Aker (owner of Fast Cap) will take of you (in a good way).

You need to Google. There are mods to catch the dust better at the blade for the Dewalt. I had the older version of that saw and added a rubber boot to the blade guard and it diverted the dust better to the hose attachment, sorry no pics. It improved the dust collection to 90%. The fast cap I have and like, but it will still be messy in a house. Look for the DeWalt dust  collection mod and get the fast cap and that should do it for the Dewalt.

 

[Alan m]

every thing i have read says that the rubber will colast with a vacum. i might try to put a new DC port on for the vac

Forget the cap, just try hooking up you Ct22 to the dust port and then make sure the little rubber throat on your saw is held open when the vac is running. You may find that you have pretty good dust collection.

I have a Bosch 5412 and put the Fastcap hood on it.  It caught the big stuff but the fines still float out and coat everything.  I added a shroud to the back of the blade guard and hooked it up to my CT33 with a rubber no-hub plumbing connection and it gets all the fine and about 80% of the big chips.  That works better than the hood so I rarely setup the hood anymore.

 

[Alan m]

sorry i know this is a stupid question but this is lost in teanslation between europe and the us . what is a no-hub plumbing connection .
i was thinking of a 4 inch funnel with a 1.5 inch outlet and putting this onto a piece of waste pipe that i will bolt to the saw

Rubber collapse? I think you are talking about something completely different. The rubber you use you need a saw to cut, a vac can't come close to collapsing it. Heck you can stand on it. I have done it myself. You are not finding the right mod, If I have time I will find it for you. 

 

[Alan m]

our wires are completly crossed on that one.
i think what you mean is that you build a ramp or shute onto the DC port to make it bigger. have you got any links or pics. maybe tell be what to google, i tried lots of things on chopsaw dc etc and DW DC

Here is the set up I have for my Makita slider.

I used an old plastic bin with a dust port cut in the bottom (screwed and caulked on).  I screwed the back of the bin to a post that sits on a platform with casters.  My regular DC unit has a hose that goes to the chop saw.  You can see the pvc pipe that directs dust to the bin.  I think a better arrangement would be a dedicated vac on the back of the saw plus the bin.  Even so, I am very pleased with this solution.

(I hope the picture is attached.  Cannot tell...)

 

[Ken Nagrod]

For Alan or anyone else wondering, in Mike's picture above, in black, attached to the saw and pvc pipe is what appears to be a no-hub connector.  Maybe Mike could just verify that for everyone?

That's a nice mod Mike.

I have no pics. The mod I was talking about Alan actually diverts the dust at the point of the blade, about 2" behind where the dust comes off the blade. It uses a hard rubber(or hard plastic) chute to funnel the dust from the blade into the factory dust port on the saw. This mod is not at the exit of the factory port, but at the inlet of the port. About 50% of the dust flies all over and never even gets into the factory port on the DeWalt. At least that's how it was on the older model I had. The saw seems designed similar so I assume you get the same thing.

Funneling more dust into the factory port really helps. Even if you hook up the best vac in the world to the Vac port outlet the other 50% of the dust just sprays and floats. The catcher behind the saw works okay to get a lot of that, but a lot of dust still gets in the air.

If I can not find a similar mod on the web I will draw one up in sketchup in the next few days..

Hi, I think you are referring to this. I made the same mod to my slider and while I dont think it is a good as a kapex - makes a huge noticeable difference. One thing to also make sure is that the ports are clear. I only realized that the saws ports were clogged once my saw started making a mess and had dust all over it.

Forgot to add that the saw has to be connected to a shopvac or CT.

 

[mike1967]

Yes, it is a no-hub coupling.  I have often called these things mission bands.  Easy to use, pretty inexpensive, air-tight.

 

[Wonderwino]

The no-hub connections are available in a number of sizes and configurations in the US.  They constrict without folding when a metal hose clamp is tightened.  I don't know what they call them in Europe or if they are available.

The mod posted by bijeshj is what I did to my saw, only I cut "fringe" on the lower half to let it clear taller stock.

Thats a good point. The "hood" I created is fixed to the saw via Velcro and I have a smaller one for tall stock.
