Bushwacked

hah! all good ... I too was super surprised at how loud the exhaust was over the motor ..

I hooked up the CNC for a few run and its working beautifully for that ... I started working on the ducting for the garage, but need 1 damn piece no HD had in stock around my area so had to order it and should be here tomorrow. Hoping to get everything installed and hooked up by this weekend?? depends on how cold it is in the garage and if I feel like doing it haha.

I might even take a look at this as well. the first couple tests with the box were not all that great. I do have some gaps on the sides which I am thinking about filling, but thinking now if its even worth it as its still pretty loud. the panels did not cut out 50% or even close haha. So that is why I may give that muffler a shot and see how that goes.

so, I am sure @Kev can go way deeper on the MDF application and all that based on his experiences .. I dont really know much about that. However, the box I am making is actually to reduce the exhaust sound. The motor is actually not that loud compared to the exhaust. So that is where I am attacking this first.

welcome! It would be awesome to see a journal of a clock build! Beautiful work like Kev mentioned for sure ... Looking forward to the seeing more on the current builds too

mine are 3/4" with 20"D base and seems about right ... I think anything thinner might look "off" ?? If you were just a little under 3/4 I think it would be fine but not much. If you were making a smaller one, I think you could get away with 1/2" That's just my thoughts lol

yes

ah missed that comment ... yes outside rings. 4/4 original board my CnC just to get it done quick

what rigid foam are you talking about? It will be enclosed with 3/4 ply ... its gonna be a heavy B! haha all good, I like when you get on a roll and I get some paragraphs out of you ... always learn something. I was thinking about doing a double layer with a gap in the middle with those tiles as well to possibly make it even better. Hopefully will have a good amount of it finished up tomorrow to hopefully get a test on it

Sanded with a 2000 grit foam pad to just get the nibs off after spraying it … then applied my BB conditioner and this one’s a wrap! Learned a good deal on this one haha. came out way better than I thought it would a few times after some issues but if I ever have to make another one it shouldn’t be as bad haha thanks for the help through this one guys!!

oh awesome! Definitely will be looking into this once I get my box built .. So dumb sound question ... IF this thing reduces sound by 50% supposedly, and those tiles I linked above reduce by 50% as well ... is it safe to say I could, in theory, reduce the sound by 75% with both?

Also .. talked to my bro in law about noise reduction ideas … he thought the powerful blower might blow apart the more porous foam type panels. He thought maybe the ceiling tiles might be better. https://www.homedepot.com/p/USG-Ceilings-2-ft-x-4-ft-Radar-Basic-White-Square-Edge-Lay-In-Ceiling-Tile-carton-of-8-64-sq-ft-R2310/203628901 something like those and just double them up. the NRC is 55 supposed to reduce by 50% ish which should be good enough I think.

I must be behind ... I have never seen either haha

Got some more work done on it … then started on my super silencer box build 🤣 .... It had been so long since I worked with HD 2x6 pine, cant say I missed it. cupped/twisted/garbage and those were the straight ones haha. I had 1 board, THANKFULLY, I took to the bandsaw after it gave me some issue on the tablesaw that blew apart the last 6-8 inches there was so much stress. Put them back together after that, there was like a 3" gap in the widest middle part of the boards without dust collection it’s such a dang mess after just a little cutting. It’s crazy!!

true, just thought it was blocking out more dbs ... have you thought about finishing it out or you good with how it is now?

even behind the wall?

Great tip for people coop! Any reason you didn’t add in the cyclone attachment before the barrel?

There’s the noise readings I’m sure it will muffle a little bit more with everything hooked up, but for now it’s hitting around 90ish dB

Here’s the motor mounted …

I did just stumble upon this ... Which leaves me with a couple questions ... How is he cleaning out his fine dust? Assuming after a year or so it would need some cleaning?? Just unscrew from wall and clean? What is that foam stuff he is using? Standard Insulation panels? Would adding 3/4 ply instead of the 1/8 hardboard from what it looks like add even more noise blockage? Not sure what type of outdoor paint/protection would be needed to stop rotting from the elements?

got the dust collector mounted and everything ... did a noise test and daaaaamn this thing got louder is seems. Wife heard it and threw a fit about pissing the neighbors off. Soooo now I am trying to figure out a way to decrease the noise of the outside vent. Anyone got any ideas on muffling the sound? I found this ... https://billpentz.com/woodworking/cyclone/muffler.php Not quite sure what the final product should look like since none of the pictures show up and some of the materials I am not familiar with. I will go grab pictures of it in a little bit, forgot to get them after installing it.

very nice Coop!! Will the 43 to 38 drop in suction actually be noticeable? Also, what are the wooden hanger attachment things holding onto the pipes? How are they attached to the ceiling?

so overall, I like the way it came out ... the bottom is annoying with the gaps, but I guess you dont really see it all that much so I can get past that. The height of the edges I think actually are a perfect height, 2" on those, with the 1/2" bottom. Still real light weight ... but I did use alder, so weights may vary with some other woods. - the glue up .. I would look for a better way to go about that. The struggle was real with that one haha. Not sure if there is one?? But I would be up for trying something else, it was messy and was probably red lining the working time of the glue. - I would more than likely also go with Kev's idea of the donut model to make it a perfect circle on at least the inside (ties in with the hatred of the gaps) Plus this would alleviate all the glue that I apparently missed cleaning up on the inside that was an absolute nightmare to hand sand off. - Cutting out the pieces, I would make sure the sacrificial fence was on both sides of the blade. A couple people had some tear out and when glued together those spots look kinda goofy.

LOL! I cant wait to see what kind of dust comes flying out. I am curious on noise level of it blowing out there too .. think that will piss off the older neighbors more than dust haha You dont remember my garage update thread from like '20? 😞 But yes, 3 of the 4 walls are 3/4 ply to make mounting anything and everything easier. Awesome to hear!! Do you have some before and after's of the new setup on here yet?

Got some work done on this too … gluing up
