The simplest charcoal powered furnace for casting

This may be the most simple furnace for melting zinc there is. That is other then just a big pile of coal. I melted the zinc using a charcoal chimney that is normally used for starting a grill. I have always loved this product for starting my grill beacuse I always have newspaper around and don't need to buy fluid but now I am even happier. I just used a small can for the crucible and a larger can for a lid.

I pinched the can a little to make a nice pouring spout.

Zinc ingots are available at rotometals.com

I don't belive this is hot enough for aluminum but i did not have any on hand today.

Bamboo trellis for hops

This turned out to be a fun project all I used was twine and 15c bamboo from construction junction. It is about 10' tall and tied to the gutter.



Now hopefully this little guy will but up to the task.

Got lots of these flowers. I hope they actually turn into cones.

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:

sad day. I loved these ad's. I guess we have till the end of the month to enjoy them.

IKEA LACK record player stand.

Here it is the Official Mike-is-bored IKEA record stand. this is made of three Lack coffee tables stacked with 3M Scotch Mounting Squares. The top table was found by the trash with a missing leg and the others were from a friend who was moving. Should be pretty easy to score some of these ugly tables if you want to make your own. This LACK stuff pretty much belongs in the trash anyways as the one or two screw ins and you will strip them. The turntable is easily accessible from the missing leg. If the stickers are well attached the area above can support a fair amount of weight.

Not really brass? A future of sun powered Fresnel lense casting?

Official Google Blog: Will it lens?


As cool as this is I challenge the statement that the this middle penny is brass. To heat enough to get that alloy you would first need to melt the zinc and then the penny would be much more deformed. Heated pennies go thorough a lot of color changing phases. The middle penny is the suspect one.



Friends if you are reading this please buy me one of these giant ones. I would love to try to do zinc casting powered by the sun.
