Modular Metal Casting Flasks (part5) - 3D printed modules - pattern updates

[@swdweeb]

Dang, I wanted to be the dislike and someone beat me to it 😆 Absolutely nothing to dislike about this video mate. Well done. Now fix the gate size on those feeders and cast it! 😆😆

[@JulianMakes]

swdweeb haha thanks buddy!!! The good news is I’ve actually just sorted those feeders out properly (and the two modules they fit into), I’ve guessed at 11mm feeder gates for the first go, the prints will be running over night for casting tomorrow!!! Omg so excited! Thanks again for your awesome help mate!

[@swdweeb]

@@JulianMakes Well, you've got people all over the world excited to see the pour... no pressure 😆

[@ralphmourik]

I admire your determination for this project, I just love watching your work, can't wait to see where this will go! 👍👊

[@JulianMakes]

Ralph Mourik thank you so much Ralph!

[@stoneomountain2390]

The slots can be done with a core method like how they cast cylinders. All these fancy innovations, it'll be awesome to see how they turn out.

[@JulianMakes]

Stone o'Mountain thank you stone’o

[@RotarySMP]

Great tenacity. I really like this latest design. Look forward to seeing your casting, and your release on Thingiverse.

[@JulianMakes]

RotarySMP thank you rotary!

[@RotarySMP]

The spruce and gate look great, although you have sharp corners in the cross, where the melt will probably knock loose sand off the corners.

[@swdweeb]

He can always smooth the corners in the sand before he pours

[@tobhomott]

Amazing! I think you've got it nailed down, you may not even need the feeders since the changes in thickness have now been decreased bigtime by removing the fat ribs. Those gates on the hopefully unnecesaary feeders really do look a bit small, but hopefully that's moot anyhow. I hope you cast 8 sides... we want to see a whole flask assembled! 😀 No pressure. Great job!

[@JulianMakes]

Tobho Mott thanks mate, yeah I’m feeling good forfo this one, it just looks good, it better cast ok omg! I’ve actually redone those feeders tonight to be finished for tomorrow’s test casting (I hope!) cheers 🍻

[@John-kc7ko]

If you alternate the holes and fingers, I think you can get rid of the chirality.

[@JulianMakes]

John omg!!! ‘Ahhhhhhhhhhhh’ this didn’t occur to me as I was trying to reuse the old slots to save time (and they dictated where and the order on the fingers). If this casts well I shall certainly do just that when I sort the slots and feeder pin areas. You beauty John!!!

[@John-kc7ko]

Happy to help! I love your channel :)

[@videotracx]

Your videos provide some interesting concepts and information. I have a 3D Printer is used for personal projects. We also have a large Kiln to melt metal. I want to try this. Thank you for posting these videos and sharing.

[@JulianMakes]

no problem videotracx! my pleasure, thanks so much for your comment (sorry this is so late!)

[@gordon6029]

Should give a shout out to Myford Boy. Basically his design.

[@MeltandCast]

Brilliant Julian... Can't wait to see how this works out, this looks a lot better than the previous versions. If you do use a feeder, let me share a comment from Olfoundryman on my first aluminium casting, which shrunk horribly... "it should have connected to the casting via a gate of length about 1/2 the feeder diameter rather than be hard up against it. this gate should flare from about 2/3 the feeder diameter at the casting to full diameter at the feeder in particular it needs to flare a lot on the top side." I think what he is saying is that i needed a lot more contact area on the casting, a wedge shaped end to your feeder connected to the casting rather than a pointy end should do it. If you want more context to this you can read the comments from Olfoundryman in full on my moon video. It was aimed more at my failure to construct the feeder corrrectly and my use of poor aluminium stock, but I think this general rule on feeder shape probably applies to any casting. He also mentions that my incorrectly constructed feeder had the opposite effect and actually sucked metal out the casting, so I think it might be worth your while having a quick flick through the video where I build the flask and reading his comments in full. Of course this may be mute, as your casting is a lot thinner and you are using much better stock. Anyway good luck with the casting, hope to see all 8 sections soon.... (I apologise for referencing one of my own videos in your comments, please feel free to delete this comment once you've had a look). Best wishes Andy 👍👍

[@JulianMakes]

MeltandCast thank you mate! and do not worry! I will def have a look at your moon video and the comments too. Cheers so much for the advice, I’ll do it tomorrow while I’m waiting for the new (fatter gated feeders to finish printing). If I get time I’m casting it tomorrow. Omg can’t wait!

[@MeltandCast]

@@JulianMakes Haha I can't wait either !! Good luck mate 🤞🤞🤞 Cheers 🍺

[@askquestionstrythings]

You could make those feeder gates oblong in shape. Like a oval or rectangle coming off the cylindrical feeder to match with the area you have to work with.

[@markusjohansson159]

Its looks great

[@JulianMakes]

Markus Johansson thanks Markus :)

[@markusjohansson159]

@@JulianMakes I believe you can modifie the wider riser to fit both middle pieces.

[@raschellesherwood6347]

Wow omg I need to see you succeed with this awesome project of yours.. so pour the bloody thing lol. Glad to see your Gunna have some good size feeders... They might be a little small but my fingers are crossed for ya. Also you may have to encorperate some flow extenders to travel the distance, 8mm hmmm I can do 10mm sheet at almost A3 paper sheet size no problem without flow extenders. I'm very excited to see you complete this.

[@JulianMakes]

Raschelle Sherwood thank you so much Raschelle!!!

[@stevebray71]

Could you have the dove tails where the pins are printed separately so you may be able to to the top modules together and you've got the best on both counts

[@imconfused666]

I really love this project and I am currently printing what I need to cast my own. Printing on a CR-10 and my one complaint (probably caused by me doing something wrong in my settings) is that the fingers fit so tightly in the grooves, I have to really hammer them together and then they cannot be separated. What am I doing wrong?

[@JulianMakes]

Hi weasel. Thanks for your comment and tyring them out! Quite a few people have made a flask with them now and a few people have complained that the fingers are too tight. I guess it's just variation between printers because some have said it's perfect fit. some of those that say it's too tight have had sucess with trimming off some of the finger length (for example halving the fingers), that way the friction to remove is way less and they may fit together better. I'd suggest trying that. i really should do an update on these designs some day. and i think i should revise the fingers to be shorter and more blunt to allow more printers to print them and have them work ok for the most people. Thanks loads and if you manage to make a flask please send me some pics :) cheers o/

[@jaredjones6570]

What is stopping you from casting each modular piece separately and then assembling whatever flask you need whenever you need it? Is it really just the shrinkage in the aluminum parts that makes tolerances hard to achieve? Or is it that you're worried that it won't be rigid? If you could quickly make any flask dimensions whenever then you could save on sand, upgrade over time, potentially have less to lift, make several mini flasks that are independent for the same pouring session, and easily store the pieces in a box until they are needed.

[@mikeharmon4901]

Use a belt sander on green part to remove bow?

[@charles1379]

Julian, teh runner appears too small a cross section and causes the melt velocity to be too high

[@WarGrade]

STOP hammer time...... Errrrrr no no no not hammer time just stop!!! ( I will email you asap) Ok your feeders will freeze before they do any good and quite possibly do harm. Your size of feeder I'd be looking at a 10mm o/d join (absolute MIN) with the bulk as close to the pattern as possible. loving the redesign too

[@stevehonour9668]

Were not awesome you are !

Steve Honour haha thank you Steve! You are awesome!
