Boots and hoods versus straight duct efficiency - 5 replies

In terms of efficiency and loss of CFM, what is the difference between using a HVAC tapered air handing boot at the bottom of a miter saw hood versus just cutting a hole for the 6” duct? The cost is about ten bucks and difficulty is essentially the same. You can install an HVAC boot on the bottom of a miter saw hood which is a 4”x...

Actual numbers for comparing a long radius 90deg vs 2 45deg elbows - 7 replies

My main ducting is all above the 8’ ceiling of my garage workshop. For my drops I have enough room to use a 45 deg wye to the wall, straight duct, and then a 45deg elbow down the wall. I also have room for 90deg long radius elbows. I keep reading the rule of thumb upside to the dual 45’s is less CFM loss compared to a long radius ...

duct transition change in elevation, or why parallel lines will never meet without an angle - 13 replies

My cyclone is in a big closet off of the garage. The ducting will be above the ceiling. I need to go from the 6” inlet from my cyclone up and through the ceiling of the closet where the ducting will run across the joists and drop down through the ceiling at the machines. The inlet to the cyclone has a bit of an up angle but not enough to ...

fan cover optional? Missing fan cover on Delta 83-651 - 8 replies

I picked up a late 40’s Unisaw that has been rehabbed with a 3hp Delta 83-651 motor. It is missing the fan cover. To my way of thinking this is not essential. The motor is TEFC “totally enclosed” and the fan itself is protected from chunks of wood dropping through the insert. So, no fingers or foreign objects to contend with, i...

Accurate Technology DigiFence vs. Wixey Saw Fence Digital Read Out - 6 replies

I did a search and found a half dozen reviews of the Wixey DRO but nothing on the Accurate Technology DRO. There is a significant price difference but it’s currently on sale. Sometimes more expensive units are less fiddly, sometimes not. I would be interested in anyone who actually has experience with the Accurate Technology DigiFence to w...

Miter saw hood Ducting question and muscle mod - 5 replies

No one would confuse me with an engineer. But I have an idea that I’m going to start playing with in a miter saw hood build. I will have a 6” drop coming down into the top of the surrounding plywood hood. The saw is a 12” DeWalt that is pretty messy but there are hacks that make it’s dust port more effective by widening it with wings so it funne...

I have never heard of Soontools and I haven’t found any reviews for their equipment. Anybody know anything about them? This seems a bit risky but the Siren song of cost savings has got my attention.

Anyone have trouble with clogging Clearvue mini-cyclones? - 5 replies

I am building a cart for my Clearvue mini using the carcass/cart of an old dust collector stand. There is going to be a vacuum unit built over the top of the mini eliminating the hose. The mini will be “permanently” sandwiched between the vacuum motor and the bin lid making the mini-cyclone to be difficult to get to if it were to clo...

12" Disk Sander choices; $100 range of distinctions with no difference? - 8 replies

I have looked online at 12” disk sanders from Harbor Freight, Wen, Shop Fox, Delta, among others. There is an old saying that there are distinctions with no difference, and all of these sanders look like they got squeezed out of the same mold. Maybe there is better quality control between the Delta and the Harbor Freight, but the Harbor...
