I presently have 4” flex line running from my HF 2HP DC to a 4” S&D nipple from my Thien separator. I want to up-size this to 5”, and I have found 5” flex, as well as clamps, and 5” stove pipe that should work, but what about the elbow, or is this an opportunity to go side inlet screaming at me?

The whole point behind wanting to do this is so that I can use the HF 5×4x4 Wye fitting to branch off with a blast gate so that I can run a 4” port to my shark guard. (I am upgrading, and getting rid of the shop vac for all dust collection, going totally to the DC / Thien rig, except of course for sanders…

David, If you can can accomplish the side entry it should eliminate up to two bends in your airstream and help keep the volume up.

I am wanting to, but a bit fearful of chopping up my barrel without knowing EXACTLY how to do this…

I posted about the separator HERE
Thien separator. Thien separator pic 2

it’s a pretty basic 55 gallon drum with the ports set up through the lid. I can plug the hole for the inlet elbow but I need to know how to make the hole for the side inlet. I am thinking make the right hole, pass a piece of 5” stove pipe through, line it up the way I want, mark it, make accomodations for mounting / screw tabs, cut and clean up with the Dremel, install, seal with clear silicone…

Would that be the right track? Eliminating those 2 bends would go a LONG way to making my system happier…

FWIW, I am thinking about grabbing 5”x10’ wire reinforced clear hose from Kencraft as well as the 5” hose clamps and 5” Snap Lock pipe from there as well.

The thought process is to EVENTUALLY upgrade to a full 5” main trunk, and use 5×5x4 Wyes to the machine drops. That SHOULD maximize what I can get out of the HF DC… I think…

OK placing the lines horizontally would only lead to problems so don’t cut up your barrel for nothing, the easiest method would be to place a 6” dia PVC 90 degree elbow in place of the current one on the outside feed and fitting the 5” pipe in the 6” duct using a converter ring made from wood plastic etc. the other thing would serve as a nice shop project is to build a drop box separator large wood plants us these with air locks but building one from plywood would serve a better purpose as far as lineal air flow to your D/C you can Google drop chip separators and get a basic idea how these things work.
keep me posted:)

Well, I can use a 5” adjustable elbow I guess… Going from 5” to 6” at the elbow sounds like trouble to me. I am probably wrong but it sounds funny…

I can’t find it but there is a website that gives you a formula to make templates to install the pipe into the side of the barrel. AHA found it http://harderwoods.com/tools.html

Okay, check my sanity here for me will ya?

If my drum is 23” diameter (according to the MFG specs it is…), I enter 90 degrees for the joint angle 23” for the diameter of the main pipe, 5” for the branch pipe, and .0276” (24 gauge for sheet metal) for branch pipe thickness, with a lateral offset of 9” since I want this inletting nearly into the side. The template that it spits out looks a LOT like what I expect the hole to look like…

I think that got me going in the right direction for sure! Thanks…
