Lowe’s Ducting (to my Griz BS)
I mentioned to Glenn that the hard DC ducting to my Grizzly BS was from Lowe’s. (This Excludes the 6in ducting going to the DC, blast gate and a piece of “stay put” flexable ducting). The stay put duct exits from a small box I made that fits under the table, right next to the blade. This 2.5in duct terminates in a wye going into 4in ducting that ends in the six inch going to the DC itself.
Anyway, Glenn thought some members might be interested. So here are the pics and a brief description.
The first pic is an overall view from the operator’s side of the saw. This shows the 4 inch duct terminating into the six inch main duct.
Second: This is under the table on the backside (away from the operator). The 15 inches of stay put ducting comes from a box I made. It is just under the table and held in place with magnets. Glenn saw this idea someplace and modified it for his Grizzly. I had to do it a bit differently since my Griz is slightly different than Glenn’s. It is amazing how well it works.
The stay put feeds into a wye. The wye consist of 4 in flow straight through with the 2.5 in feeding into the main air stream at a 45 degree angle.
Third: This shows the 2.5 inch duct into 4 inch wye, the blast gate and two 45 degree els. The two els make a 90 degree turn. Notice on the BS, just to the left of the motor, there is a 4 in opening coming out of the saw. This is to attach another hose. With this system it does not need another hose. In fact it is not even closed.
Fourth: This is an “aside” slightly off of the topic. This is a pic inside of the lower wheel cover. The sawdust in there has NOT been cleaned out. What is there is all that is there since the DC was attached to the BS several months ago.
Fifth: Meanwhile back at the Dust Collection Plumbing from Lowe’s. (Understand that any big box hardware/home store will have the same. So will places that sell to plumbers, landscape workers and others. I just happened to purchase it at Lowe’s).
This is the non-operator side of the saw and the ducting. Notice the standard 4 inch plumbing pipe and els. To attach a piece of 4 inch flex to 4 inch plumbing els, tees, wyes, etc. cut off a four inch piece of pipe and fit one end into the el. Two inches of the regular pipe fits into the fittings for 4 inch plumbing. The 4 inch flex will stretch enough to slowly fit it over the pipe extending out of the el. I doubt that it will work if it is cold.
Tomorrow night (hopefully) I will show pics of the small box that fits under the table next to the blade. I think the pics are good enough that most 17 inch Griz BS owners can make one. I say most owners because the design of the saw has been improving over the years. I made a mock up using cardboard from a box, blue tape, razor knife, scissors and a bit of patience. (the last phrase in that sentence will come as a surprise to Glenn and Myrna) If you need help PM me.
OK I added a pic. However you have to lay down to view it properly. Notice the piece of 1/8 inch thick plywood that was added just after the blade enters the lower wheel well. This is a Zero Clearance Insert so to speak. The dust carried down by the blade now goes through a small compartment and is moved out into the 4 inch duct. There is also a brush that wipes the inside of the blade in this compartment.
If you look at the thread "Glenn n JimB BS Total Dust Collection Solution" (or a name very similar to that) you will see what feeds the 2.5 duct just above that 4 incher.
