Hi everyone, thanks for your input. The baffle box is working as designed and the room air is now running through the box before entering the Glowforge. The baffle box and Glowforge are mated by stacked pieces of plywood cut on the Glowforge to fit around the vent. Four pieces of 1/8" glue laminated plywood make up this mating piece. I adhered this mating piece to the bottom of the Glowforge with cyanoacrylate and activator. Filled gaps with cyanoacrylate because clamping pressure dented wood.
Four pieces of 1/8" ply wood glued together. There’s an .svg file if you want to make it yourself. You need about a half inch thick mating piece to make it from the bottom of the intake fan to mate to a hole level with the table surface your Glowforge is resting on. Note: only make this if you intend to reroute intake air from somewhere else, resting this on a flat table will result in no air being brought into your Glowforge. Look at the top of the thread, there is a hole in my box.
That circle to the left of the intake is a speaker. It draws no air.
Fits around the torsion bar support.
So, was this baffle box successful at abating noise?
Just like most people suggested, most of the noise is coming from the exhaust duct. Because I have a pro I will next make a box that totally encapsulates my Glowforge, and doubles as an outfeed and infeed table for utility of the Passthrough slot. I will keep the baffle box and incorporate it into this next box. Noise will most likely be reduced drastically. And I’ll incorporate the insulated exhaust duct into the design
An aside, I am super happy with the Kilmat sound deadening product, very easy to apply and works well.
Will keep you updated in a new topic when I build the Whole Enchilada Box.
