Thank you!Rupes wrote:I think its fantastic. Its one of those things that open up new ways of making things you never thought of before. Who needs a 3d printer that makes useless nicknacks when you can melt down some scrap and pour your own castings.

Cool. Well, maybe HOT! What did you make the crucible out of? And what is the heat source fuel for this? Just curious as it does seem like it could come in handy for rough castings of aluminum. How much do you have in this build?exnailpounder wrote:20170206_112809.jpg20170206_110547.jpgGot her cured and made a makeshift crucible and cast this little ingot this morning. She gets plenty hot.
Fuel is propane with air assist. The crucible is just a 4 inch stainless casing cap....just temporary... just wanted to see it melt something..lol. The refractory cost me about $80, the keg, $25, the burner maybe $25. I pick up used regs at flea markets and garage sales and I am a hoarder of everything so I had almost everything laying around to build this. My friend retired from well drilling last year so he brought me a truck load of SS well casing to make shrouds out of. Being a pack rat pays off sometimes. This was a fun project.electrode wrote:Cool. Well, maybe HOT! What did you make the crucible out of? And what is the heat source fuel for this?

I too am a hoarder somewhat. Works for me. Looks like a great deal for melting aluminum etc as far as money spent. I will probably add this to my project list but my list has a lot of projects in front of it atm. Thanks for the info.exnailpounder wrote:Fuel is propane with air assist.

I agonize over getting rid of something or throwing it out to clean up my shop but it never fails that when I get rid of something, a project will show up that requires exactly what I just threw out. How the Hell does that happen?Poland308 wrote:We need to start a thread. Cheap/ free stuff that we have hoarded. If you want some come pick it up. With pics.

Hoarding can be bad if it's like 30 house cats and 3 litter boxes with 6 months of shit in em and pizza boxes with hair growing on em and a path from room to room, but shop stuff is ok right?electrode wrote:+1Poland308 wrote:Every time
I threw out a piece of 1/8" plexiglass some months ago as it was a leftover scrap (at least I think I did cause I sure couldn't find it) and a few days ago I needed a piece to fix an oiler for one of my machines. The sight glass (plastic) was found to be cracked when I was rebuilding the pump. The piece was 3/8" x about 1.5" inches long. I had to by a $5 piece to cut that little bit out of. Arrgghh!
Castings are only as rough as the sloppiness of the operator.electrode wrote:[ Just curious as it does seem like it could come in handy for rough castings of aluminum.

Excellent work there. I watched the whole process years ago on how to make the molds etc and it looks like a lot of fun. I also play around with some 3D stuff and have the software (or some that will make the files to print), and some skill, just never bought a 3D printer. I know the #D printers are really slow so that is one reason I have avoided them. What brand/model printer do you have and do you have any recommendations on the purchase of one??Jim FLinchbaugh wrote:Castings are only as rough as the sloppiness of the operator.electrode wrote:[ Just curious as it does seem like it could come in handy for rough castings of aluminum.

This one was done in 125 grit sand
3D printed patterns need to have the surface smoothed out. Most are using hi-build auto body primer/surfacers
then a quick coat of something smooth and shiny.
Otherwise, it wont come out of the sand mold well.
