OK, here are the pictures I promised.
First pic is of the box, I keep it in the box for transport. It is a bit of a hassle to put it back in the box so it so point it will just ride in the back of the truck. It on my MFT to give you a sense of scale.
Next pic is of the ChopShop out of the box in its folded state. It has Velcro straps to cinch down the nylon to make storing a bit easier, not cinched in this pic.
Here is the ChopShop unfolded, it has metal framework to hold its shape.
The frame can be folded, seen in the second pic, the metal rods have a slip fit joint with two cables inside the rods to hold the two sections to together.
Heres the rig all together, you can see it is pretty big.
To mount the unit I drilled two holes in the MDF of the Sawhelper stand. Two rods just slips in the drilled holes to mount the thing, pretty simple. It can be mounted in a number of different ways. I'm sure you could mount it to almost any saw/stand combo. Also not in the pic the Velcro straps used to cinch the unit closed can be attached to the stand to better hold the hood in place. And I have a bucket to collect the dust, a cardboard box may be a better choice.
Here are a couple more pics.
Alright, time for the good and the bad....
The good, it works well collecting almost all of the dust, some airborne dust does make its way out. It assembles/disassembles and transports easily. It doesn't interfere with the saw in any way.
The bad, its very big, you'll need a lot of space for this hood. It bigger in reality than it looks in the photos. I think it couldn't be used outside on a windy day, I don't know for sure I haven't tried it yet.
While the nylon is heavy duty (like a light weight Cordura type of nylon) the rest of the construction is a bit light weight. Long term durability isn't known yet, I could image this thing getting caught in a wind storm or a heavy piece of stock hitting it and doing some damage. I haven't used it much, so someone else can offer a better opinion about durability or general thoughts.
Overall thoughts, its a nice piece of equipment. It will work well for my needs. I won't bring it to every job, it will stay home on jobs where space is at a minimum. I cut a lot of Azek (PVC trim) every summer, since the PVC won't biodegrade I don't blast the dust in the clients yard. The ChopShop will make containing the PVC dust much easier.
My opinion of the Rousseau Downdrafter are much like Nick's. I have the Rousseau, with its own stand on wheels, with my miter saw (non slider) in my basement. Since this saw is most for cross cutting and very seldomly used for miters it works out pretty well. The Rousseau takes up much less space, but doesn't work nearly as well.
One more comparison, since the I mentioned the ChopShop in a Kapex thread I give my thoughts here too. The overall size of the miter saw and the ChopShop is much larger that of the Kapex.I haven't used the Kapex, but I'm going to guess the results are about close to the same. Maybe a slight edge to the ChopShop at the cost of a bigger foot print. The Kapex may collect a bit more of the airborne dust with the ChopShop collecting almost the dust the course dust the Kapex can't get. Keep in mind I haven't used the Kapex, if anyone has used both I'd love to hear your thoughts.
ChopShop hood retails in the US around $130 USD.
