- This is a response to Muskrat Outdoors, when he train to make a brass crawdad. My version only turned out slightly better.
Here is a link to his video. • Casting a Brass Crawda...

Watching him attach these little future bronze critters reminds me of the photography my uncle used to do. Someone once asked him how he got the bugs to stay still for him, and he'd just say "superglue"
It looks really cool! But what I really want to know is how it smelled during the burnout. I can equally imagine it being delicious or terrible.
It was too slow to give off any smell I think. I didn’t smell anything.
imagine how this would look from the view of a crayfish hahahaha
some maniac is glueing joe on a stick and is gonne turn him into bronze
😆
Another great video! I have used sandblasting and it works great BUT pressure washing works even better! A cheep electric one from harbor freight will work fine. I have seen someone use a sandblasting cabinet with the pressure washer cuz they live up north like you. With cabinet indoors you can stay warm ish and dry.
Pressure washing sounds like a great option.
Its called a Mud Bug. Love the videos. :)
Love the comparison between two methods. If shell is like bone then has high % of calcium which I think is a metal. Wonder what effect calcium has on mold, burnout, alloying, etc. Another interesting experiment some would have not published. It is great learning with you on this journey. Much appreciated - many thanks and happy holidays!
Crayfish/daddies are not so big in these parts. That one looked mighty tasty. 🙂
HOW DID I MISS THIS VIDEO??? THANK YOU SOOOO MUCH!! Ha! I need to get back to playing with this stuff! I was having fun, and watching your videos really got me interested! I've been busy with some other stuff, but I'll get back to playing with this again before too long! Thanks again Lucus!
You’ve been busy trapping! It’s been years since I’ve done any trapping.
Hi Lucas, looks fabulous just needs a large aquarium for it to live in … is there a chemical or acid that might dissolve the investment that your sculpture could sit in. Not sure if you got to see my key casting video, would love to try something a bit bigger but rather nervous of large amounts of molten bronze in my small workshop … cheers … Nick
No I didn’t see the key video I’ll look it up right now!
I will never build a furnace, own a Dremel Tool, handle dead spiders, or polish a sculpture but- I love your videos. Informatice and entertaining. You are a maker in the best sense of the word. Please keep making videos.
I want yo try aluminum and plaster of paris, what could go wrong?
Always fun experimenting as long as it’s done safely.
Thanks for contrasting the two methods and explaining the differences.
I see you using something in a tube/caulk gun to seal your flask with the vacuum casting setup. Is it just plain silicon sealant? I tried a red high temp silicon gasket cut from a sheet on my first attempt, but it burns up and is expensive as a consumable? Would love to try the silicon if it's worked well for you?
Yeah I tried that red sheet too burned up right away. So I just use 100% clear silicone. Works just fine.
Great info. Thanks! Do you cast with the silicon still wet, or wait for the bead to dry before you set your flask down on it?
@@landoncmichaels I cast with it still wet. Sometimes it bursts into flames when the flask it really hot and can smoke a lot but I try not to breath it in.
Great work, dude. I guess the grains structure on the bronze surface comes from the sand?
No that was likely do to the crayfish not burning out completely or residue that got left behind. You can see where the wax wood was it had no grain structure.
@@lundgrenbronzestudios OK, I have difficulties in seeing exactly in my small laptop. Anyways, you did a remarkable job in this case. I try to follow your tracks as soon as I get my stuff together in the workshop.
I've mostly used a vibrating tumbler, but filled with water and a couple of pounds of small, stainless-steel pins, about 3/16 of an inch long. Works beautifully, and very quickly, too. Of course, I've never done anything quite as large as your stuff, so I might need to vary the quantities and times. I know there are also pickling solutions available, but I've never tried that.
Looks so good..love the ambiguousness of the finish.
🇦🇺🤜🏼🤛🏼😎🇦🇺🍀
well on the Crayfish Crawdad Yabbie debate theyre all actually different species...Crayfish are a UK species Yabbies are of course an Aussie invention and Signal Crays or Crawdads are from the USA ....
How long do you need to leave the plaster/ investment before heating? presumably the steaming wets down the cast somewhat
Intriguing and I imagine a particularly difficult subject due to the wet nature of frozen crustaceans
I like the result but as you said it would be great to get the antennae as well.
Very cool and illustrates the benefit of vacuum casting very well.
Have you tried soda blasting?
Great job, looks a great casting.
I have a little bit. It’s a gentle way to sand blast.
Glass beads or ''bead blasting'' is very low impact.
Saya pernah mencoba membuat patung dari bahan logam ternyata sungguh sangat sulit 😅
Дякую тобі , багато чому
навчився від тебе.
I like the PLA version. 😄 Great result!
I notice that your foundry furnace appears to be a DIY from a propane tank. You might someday consider doing a video on constructing one. I'll bet that would get a lot of views.
Oh, never mind, I just realized you had already done this. My bad.
can you explain how the vacuum works? It looks like the only hole is the sprue hole for the metal to go into. How is the vacuum pulling inside the mold?
The investment is porous so air can be drawn through it.
That wax tree piece looks like the best beef jerky ever
Down in the south we call um crawfish.
As Julia Childs said, that's a crawfish.

I wonder if anyone had tried really fine wood dust mixed with plaster of Paris, to improve porosity ???
I’ve heard of that. I’ve never tried it myself.
for cleaning he should see about getting an ultrasonic cleaner. its more gentle than sandblasting and usually shines up metal pretty good
I tried one and sent it back because it didn’t work very well.
Love your channel, I learn a lot.
A pressure washer works well for cleaning off investment.
I should get one of those.
Bronze bonsai lobster.
I’d say the crawdad was too hydrated, like 80-90 % water of fleshy mass inside that shell, insects dry out and the delicate remains are almost nothing but dry paper that burns……call the guy at the crematorium he might have a body mass to cooking time chart on his wall…🤐
Well. I had it at about 400° F over night and about 1100° for about 10 hours so some sure the water had time to disappear.
More ‘residue in the lobster, like cholesterol…..that’s hard to shift, ask my aorta…@@lundgrenbronzestudios
I love your channel, I'm from VA, so of course, I say Crawdad, and I absolutely love how much you are willing to teach. I'm storing away info every time we meet.😅
Salut Lucas !
When i saw the pouring of the liquid metal i noticed something "tumbeling" from the crucible and think that second "that's not good" ...
Everithing must be perfect in order to have a good result ... perfect temperature of the liquid , not too cold but not too high either because it might boil and make bubels ... no impurities in the mould , no moisture in the mold , the cooking of it must be also perfect otherwise it will crak - start slow , maintain , descend slowly ... lots of variables ... that's why it's an "art" ...
and that's only the technical side of the "story" , the object itself must express an artistic thrill ...
Good luck for your next projects !
So good
❤❤❤❤❤❤❤😊
👍👍👍
I like your stuff. I am building a diesel fired furnace to get the max heat. I will not use a #20 crucible but would like to size the furnace to accommodate one if needed but I do not want to build one so big I lose a ton of heat. You have any suggestions on what would be a perfect size for this??
That’s a pretty big crucible and I’ve never played around with things that big, but there is a great forum called thehomefoundry.org
Those guys are very knowledgeable.
By the way, you won the drawing for the two headed coin. If you give me your contact info I can send you the coin.
@@lundgrenbronzestudios Forgot all about this. Not sure the best way to get you my info? Thanks for the link by the way.
@@rufustoad1 can you find me on Facebook at Lundgren bronze studios. Or email me at lund1060@gmail.com.
🤙👍
What size vacuum do you use 3.5 4, 5, 7 cfm ?!?
The pump I got was 8cfm
@@lundgrenbronzestudios Thank you! I couldn't figure out what is needed… guess it’s based on volume and more is better.
Why do you need to quench bronze
It’s not so much to quench the bronze as it is to quench the investment. When you quench the investment the boiling action dissolved the investment away so you don’t have to take an hour chipping the sculpture out of your flask.
Very nice!
You didn’t even have time to watch it!
@@lundgrenbronzestudios I seen the picture and it looked very nice 🤣
I'm thinking the shell is more bone like and may take twice the time to burn out and maybe more heat. Maybe as you are doing the burn out, lay another one next to it and when its gone, the one inside hopefully would be too.
Yeah. I think the next time I do a burn out I’ll try a test to see how much burns away.
no clue why this came across my home page but glad it did! watched the whole thing and learned a whole lot even though i know nothing about metal casting lol.
good on you for showing the two different methods. the final product looked great on the vacuum cast.
I guess that’s a good sign when I can finally entertain people outside of the metal casting niche. Thanks for watching!
Another nice job! Nice to see the different options!
You misspelled Crawfish!
😆
I thought they are called crawdads.
they have many names but the natives to louisiana call them Crawfish. @@stevesahr1752
Man the brother bear are you ready hit the heart strings
