for anyone that is curious, this is a preliminary idea of the rooftop exhaust fan that is going to be used

If I remember correctly, there’s an old saying…‘if you have to ask how much something is, you can’t afford it’. Usually the truth. At least for me.

Thats a beast of a laser system!! My 2 lasers which are conciderably small in comparison (12×24" beds) run around 15k each…I’m guessing that one is closer to 30-40K. So dont screw it up…lmao
If you goto ULS.com, there is a specs requirement listing for what exhaust configuration is needed…

So, he wrote back. He didn’t indicate any of this was confidential and i made it clear that we were talking about it in the forum so I feal comfortable sharing :slight_smile here is a bit of th e conversation.
“When you get it I’ll fly out and train you (and evaluate it) if I haven’t already seen one.”
I can always get my hands on a used Universal at a great price but an ILS is in the $40-60K range retail. An average machine is about $20k and a new desktop unit starts about $10K.
Whatever you do - use it in your garage or vent to the outside or you will kill yourself. And keep a fire extinguisher handy - I’m not a fan of their plastic box."
So yeah, I won’t be getting one of those any time soon. …
On a side not he mentioned some interesting software he initiated development on. I’ll be thrilled to see him and hopefully get a copy of that software

LOL yeah just a tad out of my range… but the company we’re doing the small ventilation job for bought two of them oy.
yeah I have all the paperwork sitting in front of me cause the president was doing all of these calculations - all of a sudden I hear
"Josh, you see where there’s an exhaust outlet?"
“yeah, right there”
“where”
“very end”
“oh”
“here, you take care of it”
“ooh, laser? ok”
edit: 1000 CFM at 6in of static pressure, split between two 4in ports. So were going to tie each of the 4 4in exhausts into a single ~6in duct per unit, and then tie those two ducts together into one ~8in duct, run that up to a skylight were going to convert into a roof pad for the exhaust fan and call it a day. thats the plan for now anyway

I have both my lasers come to a junction then converge into one pipe leading to the roof where the blower sits. All 4" piping. When you enlarge the diameter of the pipe, it seems you loose some of the suction…at least thats what my HVAC guy said…and the sliders to cut off air from the outside are a must…
Dont mind the munchkin in front of the lasers…lol

lol, yeah that was my impression as well (loss of suction when you increase the pipe diameter. however I am just the peon that does whatever the engineer suggests 
till I finish getting my degrees anyway lol
edit: I’ve been meaning to say that is such a cute picture. once I get the GF, I’ll have to take one with my daughter standing in front (significantly out of arms reach - she’s in the everything-is-a-drum-to-beat-on-and-or-knock-over stage… It’d be a miracle if I could convince her to have even one of her arms by her side at any given moment

In general, girls are easier than boys.
Don’t remember the artist, but he wrote a song for his daughter - “Butterfly Kisses and Hugs” that was a hit for him.
In an interview he was asked if he was going to write a song for his son. He paused and said yeah, called “Get Down off That”.
@smcgathyfay, if I may ask, where did you find the air gate?

I remember that song - My parents used to sing it to me all the time! Ahh, the soothing memories of being a difficult child

Oh I dont know about that…I’ve got a pretty strong willed daughter…lol
I got the air gates from my laser distributor Engravers Network.

Yeah, I’m absolutely positive that ours has inherited my (and her mothers, but you never heard me say that ;)) positively unshakable stubborn attitude. she has not even learned how to speak more than single two syllable words and yet she somehow manages to effectively convey how supremely irked she is by my abilities to move her away from things she should not touch. I have never had anyone hang their head in such an exasperatedly disgusted fashion at me before. I don’t know how much longer my poor soul can take her disapproval lol.
and she’s going to grow up knowing how to use a laser… oh lord
yes, I am guilty of quoting myself quoting starwars. I’m bored at work

Oh, I have one too! My mother called it “pig-headed”. … so I know where she got it!
Mine is 24 now, and that characteristic has served her well. She thinks for herself.
Hehehe, @dhanvinddvs you reminded me of my daughter before she learned to speak. You knew she wanted something in particular because she was so animated about it but couldn’t make us understand. She would try and try, and we kind of played charades trying to understand. She would turn red in the face from frustration and disgust at being unable to make herself understood - then bust out in tears.
You could see that little intellect stuck inside this little person who couldn’t communicate.

Mine is now 25…very accomplished for her age.
She started speaking in complete sentences at the age of 2…(and hasnt shut up since…lmao)

yes, it’s quite beautiful and frightening at the same time - beautiful because you’re just so darn proud of her, and terrifying because you’re pretty certain she’s already smarter than you are, but hasn’t quite figured out how to express it verbally yet.

I am so looking forward to the day she has mastered the art of the silver tongue, and yet oh so fearful of the verbal lashings that I know will hurt so much[quote=“printolaser, post:2, topic:1711”]
