I thought some of you might be interested in this. I was looking for an overarm dust collection for my Unisaw and I looked at everything from making one to all the manufactures. I knew I wanted as big of hose connection as possible 4” is what I wanted. I wanted it to be clear and have lots of room around the blade. I am getting ready to set my shop up with a clear vue cyclone and all metal ducting and decided to tackle this first. I went with the grizzly because from what I could see from the pictures it looked like it could be converted easily for my space and it had all the features I wanted. The price as usual from them was also very good. It came packaged nice and because I have my table saw up against a wall and space is limited I knew I would most likely not be able to use their stand. If someone wanted to use the stand it does looks very sturdy. Here is some pictures of the simple bracket I came up with. I am using a small clamp to keep it locked into position for now until I come up with a better idea.
I had to cut a lot of the pipe off to shorten this up for my space.
