Hi All… As some are aware, I’m getting lose to completing my backyard workshop, it’s 12X21, with a 6” comcrete poured floor, because my shop will have not only woodworking tools, but some metal working tools as well, ...a BF20Lv Milling Machine, as well as an aluminum / steel build 30 X 50 CNC router… noise is a factor, therefore I am making the building as ‘Sound Proof” as I can… I am using resillwent channel on the walls and ceilings, to cut down on vibration…. also… all the “Contact Points” where the drywall meets the R Channel are having foam inserts sandwiched between… that and some good ole’ ‘Cross My fingers and hope for the best. So here’s my question, I will be building several work benches around the walls of the shop….also the Milling machine comes with a metal stand…. now what I’m wondering is…. should the benches…. in particular the CNC router, and the Stand for the milling machine…simply rest on the floor, or be bolted on….also… would I be better off cutting heavy foam mats ( in either the resting or bolting scenario ) and sandwiching them between the Benches / stands and the concrete floor? keep in mind that sound is of course vibration…and I don’t really know much about how vibration travels through floor. Any help / suggestions or advise, is greatly appreciated… I want the shop to be as soundproof as possible… but I don’t want to waste time and or money incorporating something that’s not going to help with sound.

Cheers

Paul

It might be a good Idea to put down a few inch layer of foam… I am just worried about loss of balance…

On a side note: Besure to have your metal working machines on the opposite end of the shop as the woodworking machines… it sux to get metal in your wood…

Yes true enough… the layout plan is to have the metal working stuff and woodworking stuff at opposite ends. I’m alos thinking of building enslosures for both the Milling machine and The CNC Router. I’ve got quite abit of gear to go in the shop… so the closer I get to completion.. ‘Space management” becomes more & more important.

If I put a ‘Significant” amount of foam on the floor as a seperation… I’m thinking I would definately have to bolt the benches to the floor… so the delima arises… does bolting to the floor negate the help that the foam added? Oh the dilemas!...lol

Thanks

I have used those thick rubber truck bed mats under equipment before, they help. But it sounds like Shopgurlyl may have found something that is made for it.

I would hesitate to bolt anything down that didn’t have to be bolted down. I tend to rearrange things all the time so I’ve made it a habit to put almost everything on wheels. If it’s feasible put the CNC in an enclosure that is lined with foam on the inside.

I worked in very large aerospace factories programming giant machines that were all isolated from the surrounding structure but bolted to 6 feet of concrete. The isolation is a hole cut in the floor to pour the foundation for the machine bound by a rubber sealer. I have fought with machines that were not correctly mounted and chased consistency all the time.
I am not recommending that you isolate your machine, but a wood CNC moves quickly, and the quick repetitive momentum changes might move the machine, thereby affect the accuracy. I’d speak to the manufacture rep to see what his take is on bolting the table down.
IMHO, I’d bolt it down, it takes only a few minutes to drill holes, install bolts with Pour Stone, and lock them down. You just have to saw them off when you want to move the table. In my experience this will take a lot less time than trying to find out why the machine isn’t repeating thickness as it once did.

Thanks for the Info… it’s a real dilema… on one had I’m sure that bolting things into the concrete firm, will make them very sturdy, and help with accuracy on th CNC’s… but the issuse is sound then traveling…so I’m thinking… about bolting the machines to the benches separated by foam…and the benches to the concrete floors seperated by foam…. But I’m still up in the ait over it.

If I am following this correctly I don’t think foam is an answer. I don’t think it will stand up. As someone else suggested I’d use rubber blocks and bolt the equipment to the floor isolated by the blocks. If you happened to have a malfunction of some sort you don’t want the machine”walking ” all over the place.
If you use “Kwik Bolts” when you drill the hole just drill it deep enough(even thru the slab if it isn’t thick enough) so that if you wanted to move the machine you just drive the bolts down into the floor. If you install the anchors right you will not be able to pull them out(defeats the purpose) and you would not have to cut them off.
Just my $.02

Thanks Guys…. Yes I agree Howie…walking machines…sounds way more fun that the reality of it. Although I keep saying ‘Foam… I am think rubber I wasn’t able to see the link that shop gurl posted….. and I also like the look of the Isolation pads that Traupman posted as well. My floors are an at least 5 inches thick concrete, so there are lots of options for anchors, and I don’t mind drilling them in permanantly, so all options are really open. In terms of manufactureres reccommendations….. the CNC router 30” X 60” is a home build… so I guess that makes me the manufacturer…lol… and i don’t seem to have the answer yet…. the other Mill is A BF20Lv Mill it weighs close to 300lbs…and unfortunately they make them without the ‘Noise Factor” as a consideration…lol… I sort of have to go with the..’limit / Isolate the vibrations” and I’ll cut down on noise.

BTW…... I do plan on casing both Mills in their own housing to cut down on particles, as well as the ‘Airborne Noise”..ie the source of noise from both these machines is two fold….1.) Airborne ( for lack of a better term ), and 2.) Physical contact Vibration. I think I have to deal with each seperately….at least in my imaginings.

Ahhh ok… Thanks Shopgurl… worked that time..and i can see the pic.. Those may be perfect, designed for my purpose exactly… I like the ‘Air Space” in the design…the less surface contact the better I’m sure.. Not a bad price either.

Thanks
