Re: Building a closet for dust collector
All forms of energy ultimately end in heat, so yes, 8KW of energy coming in results in 8KW of heat in your shop.
?
A 3KW 5HP motor produces 3KW worth of heat ¨C electrical resistance heat in the power cord and motor windings, sliding friction heat in the bearings and air friction in parts rotating in air. Even the work output of the motor ¨C the cutting,
sanding, blowing, etc., ultimately ends up as heat ¨C if you stick your hand in a pile of just cut sawdust, it will be quite warm from the cutting tool friction and the forced deformation of the wood.
?
It is accurate to say that a 3KW motor itself doesn¡¯t itself give off 10,000 BTU of heat, but if you factor all of the losses in the system and especially the work output into whatever the motor is doing, you end up with 10,000 BTU of heat
in your room as a result of the motor running. It¡¯s counter-intuitive, but it¡¯s true.
?
I am not an expert but I am pretty sure this is not correct.
¡°?That's about 8KW of electric coming in that all turns to heat, either motor heat, or friction heat from cutting etc.¡±
Only a small portion of power being consumed is generating heat.

Re: Building a closet for dust collector
Hey Joe, ?I live in Mesa. I used a variety of materials and staggered studs, on my closet. Most of the noise is from the return vent
You¡¯re welcome to come see the 5 hp dust collector closet if you wish.?

? Hi all, the journey of building out the new shop continues.? I am now planning a closet to house the cyclone dust collector.? Being an engineer, I have to research everything.? I found a fantastic website with data on different wall construction and the STC (sound transmission coeff) for each.
I had been planning to do 2x6 plates and staggered 2x4 studs.? From the data at the site I was surprised at a couple of things.? First, steel studs are meaningfully better the wood studs.? Second if building two walls, having drywall only on the two exterior sides is better than having drywall sides of the studs facing inside the double wall.??
I have decided to do double steel stud walls with 2 1/2" steel studs.? I think I want 20 gauge and not the cheaper 25 gauge. any input on that?
I will install 5/8" drywall inside, a layer of green glue, and a second layer of 5/8" drywall over that and then 5/8" drywall outside. If not quiet enough I will install green glue and a second layer of 5/8" drywall outside.
I need a door to access the drum and a door to access the filters.? I am fairly certain I will do some sort of stress skin construction for the doors.
Any suggestions on how to get the dust inlet sealed to the sound proof wall?? I am doing a folded duct with 5X the cross sectional area of the exhaust port for flow the air conditioned air back into the room.

Single pivot will not allow a full 180 degree articulation unless 1 arm is above the other, but then that does not work out well for the hose. ?As for extra hose, for any boom arm, you need hose going from the vac to the boom arm, across the boom arm, and down to the tool. ?Smooth pipe is better than flex for maintaining CFM.?
With this boom arm, you will have the flex hose going vac to the boom arm and from the top of the boom arm to the tool, but within the boom arm, you have smooth wall pipe instead of flex hose (except at the mid pivot point.

Looks very good. I have two questions. One, I can't quite get my head around the gears function in the knuckle joint. Is there a reason a single pivot point won't work? Two, I'm wondering how that much extra hose is going to effect performance of the vac.

Come on Imran. Don¡¯t need to be so humble. You are most definitely correct.

Of course.. Joel and I will be posting how to make this so anyone else who wants, can make their own.. all the details will be posted as well as where to buy the parts..

No..actually I drilled and used an adjustable reamer to bore the hole where I could press the bearings into the plate..it worked very well and there is no sag or loose play at all
