Lost wax casting a emblem

I'm currently working out of a bag of Prestige Optima by Certus.
Www.certus-int.com
Needing a burnout kin & a place to keep it when not in use,

 

I priced the perforated flasks on fleabay, $35US + shipping. I could make the chamber. Not too sure about the flask itself.

 

I have a question. Being ignorant on the subject.
I have a 2 Hp blower very similar to the one pictured. This blower mover a large volume of air and produces a fair vacuum.
I originally used it in a vacuum sorting machine but now it collects dust.
My question is would such a blower have any use in vacuum casting?

I'm probably not the best person to answer that. But that looks like a monster. I picture it being able to suck a bouncy house into oblivion like the place at the end of Poltergeist.
I use this one https://www.harborfreight.com/25-cfm-vacuum-pump-98076.html for my vacuum chamber (investment & molding silicone). I was hoping it could do double duty for vacuum casting, if I ever stumble down that trail.

 

The vacuum pump you listed will pull a much stronger vacuum. The one in the picture, like mine. Does not produce near as high a vacuum. It has a 2inch NPT in and out that moves a large volume of air. If you try to restrict the input with your hand. It will pull hard enough to cause moderate discomfort immediately.

Ya need a vacuum pump that will go WAYY DOWN..... Here is the cheapy I use. https://www.harborfreight.com/25-cfm-vacuum-pump-98076.html
I also suggest a plastic dome for vacuum work. Ya sit it down on a silicone mat and suck from the bottom. A plate under it with a vacuum hose fitting and a hole in the silicone mat. DONE!
Have fun vacuum crap like pudding, styrofoam peanuts and cat turds. Hours of cheap entertainment. Never apply vacuum from one of these pumps to your hand or other body parts. *ahem
Bad things can happen to you.

 

I take it you are referring to joes whatever that thing is....right?

 

Deal of the century right here!

Jason,
I saw that one when I was building my vacuum chamber a while back. After doing some math I came out with a similar price (I got a used vac pump of of c-list, already had the pot.)
That is a good price tho.

 

Not quite,
European voltage, $129 shipping.

 

I'm thinking this one might be a better option.

Yeah I saw the insane shipping and thought I should buy 3 of these! I had posted an edit. Funny it didn't take. oh well. F it.
