Acetone burnout of lost foam.

I have been looking for a way to make sure that i get a full burnout of my lost foam. I find the gas created in using the metal really makes it hard to get a perfect casting. It was suggested to me by this guy that i try using acetone.

Very happy with the result. I have not poured yet but I have a clean mold. This mold is another lost foam packaging peanut bull but with extra vents. I test all of the vents by putting a piece of paper in them and seeing if it gets wet. I have also determined the exact volume of metal needed by collecting the acetone that filled the mold. Another upgrade is the large mold in an existing bucket instead of simply burying a thinly coated bull in sand. Hopefully this will make a mold blowout impossible.

How to cut a wine bottle with acetone and a string

Written instructions below


(there is an obvious burn risk with this project. You could also loose an eye. )

• put on some safety goggles and gloves THESE ARE THE SAFETY PRECAUTIONS I USE BUT MAY NOT BE SUFFICIENT.
• wrap a string around a wine bottle two or three times and then tie it. I used kitchen string that you use wrapping meat.
• fill a pot with cold water.
• soak the string in Acetone , nail polish remover, and put it around the bottle. (presumably other flammables could work for this but I have not tried them. White gas, gasoline, rubbing alcohol..... I make no claims to the safety of this)
• light the string and rotate is as shown in the video.
• quickly put the bottle in the water when the acetone is about to go out.
• you may need to try a few times.
• this is not a good technique for making drinking glasses because the cut is not that clean. for a cleaner cut check out: How to cut wine bottles with a dremel tool, How to cut beer bottles with a dremel tool

NOW WHAT
This is the technique I used to make the hydroponic zucchini planter from a wine bottle in this post:
