Throwing my hat in the ring after making another one of my own cast aluminum flasks. This design doesn't exactly solve all of the issues mentioned...

That's great, sounds like this is worth giving a try.
This is the sort of thing I was wondering about, but maybe something that could be avoided by dialing in the amount of sand/agitator selection?...
I saw your previous posts on the topic, certainly got me thinking. My current muller also likes a pretty specific amount of sand, so that's not a...
Yea I'm talking about switching to just a plain cement mixer (paddles removed) with some sort of agitator floating in the drum. That's a good...
Been with my homemade rotating-drum muller for about a year now. It works just fine, and I've probably put an average of about 100lbs of petrobond...
Thank you! Feel free to message me if you need any advice for your project.
[ATTACH] [ATTACH] Really impressed with the detail resolution out of the sand on this one. Cast in C955 Ni-Fe-Al Bronze.
I'm making various bronze alloys from scratch for comparison/see what might be viable to make regularly vs buying and having shipped. For example...
Looking for some safety guidance for alloying bronzes containing manganese. I've been spending a lot of time experimenting with different alloys...
Thanks, I see we have similar taste ;)
[ATTACH] [ATTACH] [ATTACH] A little project that was requested by a friend of mine. These are made of my homebrew 953 aluminum bronze alloy,...
By breaking I mean complete observable failure, ie a loose estimation of ultimate strength and ductility. I am indeed only concerned with yield as...
Kelly, this is some really great info, thank you. I think I might want to clarify that what I'm trying to understand are the limitations of the...
I have some experience with design from college, but like Kelly mentioned, engineers prefer repeatable and reliable so we never touched on...
This is a good point, luckily most of what I have in mind currently are things like brackets, bases, and other custom mounting solutions like your...
By overengineering I mean taking a design that might be suitable for manufacture in a professional foundry and just adding an additional safety...
I'm looking for some guidance on how I can produce reliably strong one-off aluminum castings in a hobbyist foundry setup. At this point I'm fairly...
UPDATE: I've cast this piece a few more times since starting this thread and am seeing much less of this pitting defect in the finished products....
