I am trying to find out the best placement for the duct to be placed in my Unisaw. It was made in the 90's. The right side is open except for the motor protrusion. I do not want to cut a hole in the cabinet. I would butcher any attempt at this.
The only way I can see is to build a box around the opening. This would enclose the motor. I would place the duct in the box.
I plan on using a HF 2hp DC and flex hose to the saw, jointer, planer and SCMS. The hose would be moved from machine to machine as needed.
I understand the HF DC has a 5" intake that the two 4'' wyes come off of. I would be using only the 5'' port.
It is also in the works to use a Thien separator and a Wyn filter.
Space and cost are the main problems. My shop is in my garage. The longest run would be around 10 feet
I don't want to put too much money into a system as I am 71 years old and how much more time I have left in the shop or on Earth is an unknown.
I have never had any dust collection in the shop for 25 years and the main reason is I am tired of cleaning up dust and fine dust does present an explosive possibility. No need to expound on the health aspects.
So does this sound as though it may work?

I find my saw was made in May 1989. It does not have a motor cover. I will have to give some thought as how to make one. It does, however have the rectangular area as you mentioned.
Thanks for the help.

I found a site that sells Unisaw plastic motor covers. I need to do some measurements to see if it will fit.
If it does I would be able to do a set up similar to Fred's.
First I have to hoe out the shop and I have enlisted my grandson to do the boring work. I am a slob in the shop and it needs it now more than ever. We have built 6 Shaker wall clocks plus a few this and that's with no cleanup.
Thanks.

DC

I am still in the thinking stage. The Harbor Freight DC has a 5'' port after removing the 4'' wye. I cannot, yet, find 5'' PVC pipe. I can order 5'' flex hose that is smooth on the inside and run it straight to the DC. I could also do the same to my 8'' jointer.
I would have to build a dust port for the jointer as I can find no 5'' ones on the web.
I would probably use rare earth magnets to attach the Unisaw motor cover as well as the jointer device.
I have a 12'' SCMS. I have a "Big Gulp" device behind it that is worthless using a shop vac. If I recall it has a 4'' port. It would seem that connecting the DC 5'' hose with a reducer may do the job.
I do not like the big gulp as it is a space hog.
At present I plan on using the HF DC with a Wyn filter only. I will do the Thien separator later. Does the Wyn filter have a method to remove dust such as a built in "scraper?"
Thanks everyone for the help.

DC

I went to Harbor freight and looked their unit over. It is 110v only and nowhere on the site does it say it can be made re-wired to 220v.
I looked at various Grizzly DC and found one with a 6'' port, more cfm and 220v. It also has a 1 micron canister. I know everyone recommends a 0.5 mc but with the amount of shop time and life expectancy I have I think this will do the job.
By the time I get done fiddling with the HF unit it seems this would not cost me that much more. It is $530 shipped to the house. Some other companies want $170 shipping for similar items.

DC

Remember I have, as of yet, no motor cover. There is a rectangular area just up from the base. It would have to be seal off with plywood except for the insertion area of the 6'' pipe.
This will be down stream a bit until I do a serious shop clean out and rat hole some money. I have a 30'' razee jointer I have used very little that I may put out on the market. It is one of Steve Knight's last ones. I have several hand tools I should, not shall, unload. You know how that is.

DC

I have finally just said to hell with it. I read a long article by Bill Pentz. In order to serve my needs and cut dust to 0.5 mc the unit I would need would cost $2000. Then I have the pipe, etc.
I cannot exhaust the fine dust outside. At my age and an unknown time left WW it does not add up.
Thanks to everyone's feed back and help.
I am the most happy these days when I take a shower and nothing falls off.;)
