It’s addictive. I’ve been pacing around trying to figure out what I want to make next myself.

Thats a good idea. It’s amazing the amount of swarf vs the resulting ingut. Swarf takes up a lot of space....

Correction to earlier statement. Sodium Carbonate not Calcium

Light salt ( potassium chloride & sodium chloride. Degass the aluminum with calcium carbonate (washing powder) not to be confused with calcium bicarbonate (baking powder).

Lol. When I was in college one of the local homeless but industrious guys used to come by my fraternity house and collect all the beer cans in a grocery cart...one day he showed up in a brand new f150 truck. I often wondered how much money we literally tossed and he gave me the assurance at...

If I melt some soon I'll try to snap a picture with the steel in the mix. I obviously try to avoid it but sometimes a small spiral of steel gets through.

Yeah I only notice the aluminum if I'm pouring at night. In normal daylight it looks like quicksilver. It's kind of neat at night because it's a dull orange but shiny at the same time. The graphite crucible is usually brighter than the aluminum. The steel however is pretty bright even in...

The steel is easy to spot in the melt though since it will glow bright orange and not melt.

Oil will burn off. The steel will do as you said and either sink or float up as dross. Keep in mind the muffins are just a convenient way to store it so further processing can be done down the road. Mines kind of mixed too. If you have a strong magnet you can get most of the steel to...

I use revit most of the time for work. Occasionally cad but I pretty much stopped using cad 10years ago and went to revit. Inventor for me took over for cad. I work for an electrical contractor. When I got inventor hsm a couple years ago I knew it was time to turn the mill into a Cnc mill...

Thanks for the link. Been reading through it. I’m actually looking forward to winter. It’s some hot work right now with it being around 90f outside. What did you model in fusion? I use inventor personally but I do 3D drawings for a living so I’ve got several different options software wise.

Took me a while to decide on a tank but I’ve had this one a while and finally used up the helium so figured it was as good as any. Ive seen propane tanks used. Just make sure it’s purged of any gas before you cut it or it could be a rather enlightening experience lol. Most expensive part is...

That’s my next step. I don’t have a 3D printer but I built a CNC mill and a printer is basicly the same principle so that also might be on the horizon. So far I’ve just made wood molds except for the hinge pin since I had an original.

The little pin was for an old safe that was missing one and here is the finished rifle saddle.
