wow how good the survace of the cross looks
Thank you!
Very nice. The cross came out great good vid
Thanks
So glad to see a person using proper safety gear. Will subscribe for that only. Looks outstanding!
Thank you. I still plan on obtaining more safety gear.(welding spats for my shins and leathers with more coverage) I have been raked over the coals for my pouring tongs that I never liked that came with the forge. I would pour towards me because of the awkwardness of the tongs but I kept the crucible as low as possible so if it slipped there would be minimal splash. I have been working on a solution for several months and have a constructed a new set I will talk about in my next video. Thanks again!
Just found your channel and watched this video. Good job. It looks great. I hit like, subscribed, and smashed the bell. 👍
Thank you so much for subscribing to my channel and liking my video!
Also just founded your channel.love your casting quality
Thanks alot, I appreciate your comment. I try to make my patterns as smooth as I can with primer/filler and paint.
came out great 👍 nice work and video
Thank you!
i just added a video on my channel that goes over the noise your burner is making and how to fix it
Thank you. I will check it out.
I checked it out, thanks for posting that video. I left a comment on your channel and subbed.
@@DamonsMetalCasting thank you . good to see it helped
Good cast. I agree with you about the cast aluminium. I keep my cast and extruded aluminium separate. Subscribed and rung the bell.
Thank you for the sub and leaving a comment!
It`s a German Iron Cross not a Maltese one, the Maltese cross has eight ends. Great job.
en.wikipedia.org/wiki/Cross_patt%C3%A9e I guess it could be for alot of cross styles.

@@DamonsMetalCasting The second picture is what i know as a Maltese cross, thank you for answering.
the burner is making that noise because the air and gas flow is not adjusted properly. can try a more expensive regulator. i ended up making a frosty T burner. i bought a forge online and the flare end of the burner is too long

Nice casting. How did you avoid porosity?
I am not sure about the porosity because I think that refers to the voids inside the casting. There is a little pitting on the outside of the casting which now I believe I have better control over. Something I was doing wrong at first was not creating vents away from the mold cavity. I made them on the back side of the casting. This would cause sand to possibly fall back in during casting and cause pits from where the aluminum would flow around the lose sand grains. The other improvement I later made was using an air compressor to gently blow any loose sand out of the mold. There is also a video called "CASTcon 2018 - Latest Techniques for Castings" on youtube. The presenter explains how to avoid the metal from carrying air down with it and reduce turbulence. Using a tapered sprue helps reduce air entrapment along with having the metal flow past the mold first then evenly filling it up. That’s why I use my little 3d printed spin trap and sprue. This information I either found or people took the time to give me constructive criticism on my posts to improve my castings. One last thing, the casting sand used was very fine at 180mesh. Thanks for watching my video I hope this helps.
@@DamonsMetalCasting Has helped ALOT. Thank you
Do you use green sand
In this video I did use green sand. Its 180 mesh, which is pretty fine. In the videos that use this grey looking sand its my green sand and in the videos where I use brownish red type sand it's petrobond. Both types of sand I purchased from a manufacturer.
It came out great! Just a fyi if your didn't know, your burner is sputtering. Definitely not burning to its full potential.
Thanks! Yeah, for my burner it's off of amazon, I am not too impressed with it. It's burner is located dead center, not off center for that nice swirl of heat. I have noticed the burner sputtering, I just haven't adressed it yet. Thank you for the advice.
Not bad not bad at all. But a few things that might help. 1: Your moulding bench is drying out your sand - either paint it or get a non water absorbent material.
2: Runner in the drag and gate in the cope to the back of the casting
3: Don't ruin the back of the casting with those vents, instead just scratch very shallow and narrow vents across the parting surface from each corner of the casting 4: get yourself an air compress or so you can blow the mould out properly and get rid of those annoying little loose grains that detract from your otherwise excellent surface finish
5:Use an old power hacksaw blade or a piece of light angle material to strike off the mould, that great big steel sheet is crazy awkward.
6 And please leave the Goddamn pins in place - do NOT do a Myford with them, its just crazy. One pin hole should be a slot.... Martin
Thank you for taking the time to view my video and leave helpful comments. I just started sand casting this year. There are a few TH-cam creators that inspired me before I started sand casting and you are one of them. I will definitely try your suggestions, I really like your idea of pulling the vent off to the side, I think sometimes sand breaks loose from my vents and causes flaws/pitting in my parts.
