mmm good job I read the comments. I kept going back to the drilling of the block part as I couldn’t fathom what you had done, and you didn’t explain it very clearly.shame cos what you are teaching is a problem I’ve had on numerous occasions and would love to know what you did there at the drilling of the block phase cos it clearly works

I've built a few sound studios. It's the reverse of confining sound in a space; for a recording studio you want to keep sound out. In any case, the principle is the same: that you stop sound transmission with Mass. I.e, something Dense. For a sound studio the best is 12" of concrete. My suggestion for soundproofing for your vac cart would be to build the enclosure out of a couple layers of MDF.

You skipped over the process of making your centering jig. That's what people are coming here to learn.

You could do this much much easier with a disposable glove. Just fill the finger tip with ointment & slide it on

Thank you for the video. This is a great idea. I tried it on my Harbor Freight Bauer 6 gallon shop vac and it worked. The specifics of how I made it is a little different. I'll include them here for others who may try to duplicate what I have done. First, the exhaust hole of my shop vac was 2.25" ID, which was a bit smaller than the OD of standard 2" PVC pipe which is 2.375". So, I had to sand one end of the pipe to make it fit. In the end, I went a bit too far, so I added a couple of layers of blue painters tape and voila - perfect press fit without any screws. Doing the math like you did, the area of 2.25" hole is pi*2.25^2/4=3.976. The area of 0.5" holes on the inner pipe are: pi*0.5^2/4=0.196. So, one needs 3.976/0.196=20.286. holes. So I drilled 25 of them to be sure. I measured sound levels and I got 91-92 dbA without the 'muffler' and 85-86 dBA with the muffler, around 1 meter away, using an app on my phone. That's 5-6 dbA reduction with is about 50% like your case. I did run into one issue though - with the muffler and 25 holes, I noticed that suction power of the vacuum dropped significantly. So, I drilled a few more holes. In the end, I ended up with 41 holes (I just kept drilling and when I counted I had 41 total). This restored most of the suction power (I don't have a CFM meter to tell more accurately. Nevertheless, it looks like one needs more holes on the exhaust (like at least 50% more total area). I don't have a scientific explanation for it but I think it's because without the muffler, the air just exits the exhaust hole. With the muffler, the air needs to travel more torturous path and thru the little foam inserts. I'd love to hear a good explanation, if anyone has one.

Potential hearing damage: Prolonged exposure to sounds above 85 dB can cause hearing damage, making 95 dB a significantly higher risk level.

Too long winded.👎

I’m a beginner and have been looking for a video like this. Your video hit on just what I was looking for. I will start following you. Ty for the help!

I was glad to see your presentation here. I have 3 psi chucks that is 2 Barracuda 2s and 1 utility chuck previously I used a PSI utility truck for all my work and produced quite a few bowls up to about 6" in diameter. I just bought two Nova G3 one was the full kit the other one with just one set of Jaws I think.

booooring...

Small hole first then bigger hole. Good video!

Great Video 👍 is there an adapter for Women 😂💥😎 only kidding. Lol

Next video, how to make the jig to drill the hole, don't waste your time on this one

Wanna make a hole on 7 ft for my traditional blowpipe project.

I like your videos Ray Wayne West.

your vacuum cleaner really sucks dont it...

Thanks, great job on the video, im putting it to work... Note: pi r square , No pie are round cake are squared.😅😅

Thanks, great reviews what about VicMarc and OneWay ?

idk if I'm retarded or something but those instructions are not making any sense to me

wow did you save my bacon ,

Your filming is awful.

I actually did this twice today and it was a struggle dig your jig I will definitely use it

All the noise comes from the top, where the motor is, I tried it and all it accomplished was wasting my time.

After being so careful to count your holes to preserve the 4.9 in² cross section for airflow, you then stuff your pipe full of foam baffles? I reckon that will restrict the airflow a lot more than the little holes. Also, dB is not an absolute measurement, it very much depends on how far away from the noise source you measure, and in which direction. You can't compare two measurements unless you are sure your microphone is in precisely the same spot both times. And along those lines, I also wish you had measured the noise difference just from redirecting the opening away from the phone. I.e., an elbow and a short pipe but _no muffler._ 'Cause I bet that's a lot of it.

nice tutorial

DO NOT NEVER, EVER, EVER, NEVER HOLD YOUR DOWL IN ONE HAND AND DRILL INTO IT WITH THE OTHER (as shown, don't even think about it).

I don't need a hole in my dowels, I need punch centers for the lathe spurs, the trouble with wooden dowels, is that even though you have the punch flat ,dead center, it will wonder just like a drill bit, not because of the design of either, but because of the stubborn grain in the wood that will push the center punch or bit to the weakest part of the dowel end, and be off center, like 50 t0 70% of the time. This method in the video would work I'm sure, it's a good idea/concept. If any of you are going to try this, I think you need to get a Forstner bit the exact size of the dowel diameter, and go from there, the smaller bit, lol, may wonder on you, but a drill guide might help. You may have to do more than one 'rig' to get it right.

I just want to say THANK YOU for posting this and sharing this amazing tip. The “miracle spray” just SAVED the day for my delivery taking place @4pm! Bless you ❤

Do you have a video that shows this process for a square (or not so square) piece of wood. Eg. a pen blank. Thanks

You da man!

Explanation is not good at all. Should have taken more time.

80 from 90 isint a 50% reduction its actually only like an 11.2% reduction

Oh wow, drill a pilot hole. What a new revelation.

Thank you! I will be assembling one of these for my wife‘s vacuum cleaner! I hate that thing!

used this to make mouthpieces for cigars. AMAZING results. 2mm bit. INCREDIBLY straight jigs

Geez... The "science" is useless... And this does nothing of the motor is plain and simple LOUD!! Buy a quiet shop vac. I have 3 different brands, and the ShopVac brand is the worst! Stanley is okay. Canadian Tire MasterCraft is the quietest, and good suction too!

Not that easy. As others have pointed out, drilling the first hole straight is difficult due to the wood grain, which are going to deviate the drill bit off the wanted trajectory. And if you don't get that first hole right, then you have a problem. I find the best is to start by hand using a 1 mm think metal tool (not sure how it's called), then start to drill the hole slowly.

Its really quite simple brilliant. Thank you.

I tried this freehand and with a drill press, the drill kept wandering off center. Perhaps it works for most, but not for me.

Dude… that’s not reduced by 50%

We can see you working but we can't see what you're working with. Can't blame you if your filming yourself and you don't have a flip screen on your camera...

it would have been nice if you showed how you made the jig slower so it was easier to understand. I understand how you made the jig but how you got it large hole lined up with the larger hole.

nice thanks

Just use ear protection. Done.

Thanks. Very good and smart comments and conclusions. Always is good to learn something new. 👍🇺🇸🙏

Looks good. Boring machines rotate the stock, not the drill. Much more accurate because rotating the stock automatically corrects itself. The combination of small pilot holes and rotating the stock will give you a perfect hole.

Where is the material list man.. and bring the camera down to see what the hell your doing!! That was like watching a concert beside a column..

But how due you ensure the hole in the block is perpendicular/ true ?

Been doing that for years.A no brainer.

what about proper wood drills these drills on here are for metal.anybody got any ideas for using those.they have a flat shank mmmmm
