In this video, I make a small solid copper hammer for use in my shop. I made pattern using fusion 360 and the 3d printed the patterns in a plastic called PLA. Then I made a sand mold with a sand called petrobond.

Non-marring copper hammer was my first serious tool that I cast. I chose to keep a wooden handle, and make a couple, from 1 lb to 5lbs. The first one I made, a 3 lb sledge, I made with pure copper wire. That thing is >>SOFT
The pipes maybe still had some solder on them, which also melted, and made some kind of bronze
I love how the layers on the hammer head were captured in the sand and transferred to the casting
It's crazy how the 3d print layers stay through the process! Amazing the level of detail here!
Love your videos. Your craftsmanship is top notch. Nice work. Hope your family is doing well.
perfect for use next to live wires or electrical circuits
Copper is my favorite metal so seeing people make copper tools that look really nice is cool
Loved the hammer. Excellent point of having a hammer that won't smash or mark up materials that need a good tap. Great video.
Commenting here until Robinson Foundry collabs with us! 🫡
Another interesting chapter in tool making! There's nothing quite like the feeling of successfully designing and manufacturing your own tools. Keep up the good work.
That.is.one.BAD.ASS.looking.hammer.love.your.work.BRAVO 🏴☠️🇺🇲😃
One of your cleanest castings so far! Congratulations!
Your sandcasting techniques are spotless 👍
Your videos are so relaxing and fascinating!
Lovely work, it's fascinating to watch the process.
This is the first video where i see amateur casting with feeders and feeling system. I like it.
I love it when you make copper or other metal hammers good job man keep it up 😊
Excellent work and content, thanks for sharing!
Its a hammer that will get harder the more you use it! Thats pretty cool!
have you considered switching to using an induction smelter? if so, why are you not using one?
So therapeutic to watch! thanks.
Beautiful work as always!
I need a hammer like that! It's amazing
you need to make yourself some copper casting tools.... maybe a small trowel for carving out channels, a cone for forming spouts, a tamping hamer and maybe a levelling beam for flatting off the top and bottom of the sand
Thanks for all your videos! I setup a foundry cuz of you with the copper penny sledgehammer build. It’s been a wonderful journey!
That is one damn fine thumb-detecting swing press!
Good to have you back
Simple and useful nothing wrong with that. Hope to see it in use in a future video.
you're very good at casting. i want to try this summer
So satisfying watching casting videos like this, thanks
So explain how it's satisfying. I don't understand
Supercool - great work
Great work as always.
Came out great.👍😎
So nice and clean! Really comforting❤️
Wow thats a cool hammer!
OOh...V2.0 copper head, polished aluminum handle, 2 part hammer (where you can machine the aluminum to press into the head) [plus it would concentrate the weight at the head] Such a great design and setup! Very cool! Keep em coming!!!!
Looks like it would be great to use in the kitchen
I want to get into casting like this. Thanks for the video.
I used to make lead head mallets by taking apart dead car batteries and smelting the plates to pour into soup cans with a gas pipe handle, I sold them to English car owners that had knock off wire wheels, the lead mallets don't damage the knock off ears
Being able to hammer metal without damaging it is always handy, nice tool.
Very nice hammer. The casting was interesting to see. Regards
Totally rad
Very nice work
Nice hammer !!
We liked this!
nice design
Hammer time🔨!
Keep having fun
cool hammer for sure.
Superb!
Nice job.
Another finely-made work! I dub it "Pincher", for while its bigger sister (which I dubbed "Penny's Revenge") can pack a punch, this one works in a pinch! Also because of the funny pun.
The first think i though was: what use can have some "soft metal" hammer? Nice the addition of tin , awesome 😁
Cute dog! And nice hammer.
Maybe next time throw in pop corn 😂😂😂. Nice casting, thanks for sharing
You could cast just the head, cored to take a wooden handle. That might help bring the weight down a little. This one looks pretty nice as-is though. 👍
he did that before
cool hammer
That dog was so cute
For milling machines and the sort, I prefer rubber dead blow hammers, but copper and lead are good alternatives.
Would it be worth making the indentations in the handle deeper, and even continuing more up the rest of the handle to shave some weight?
Two thumbs way Up !!!!!!!!!!!!
Adding the peanuts could cause all future pours to have allergies now. ;)
You should try using PolyCast PVB filament instead of PLA. You should also give ZA-12 alloy a try for casting.
Very cool i love the whole need a tool make a tool thing.
Sand yer prints! Or fill them. It's worth it. Saw layer lines from the thumbnail
I'm sure you can drill the bottom of the handle out a bit to lighten it up a bit; just don't drill too far in or drill too much out, I'd venture to say you can run a 1/2" drill about 5 inches up with no real issue to integrity or strength. Cheer's...
Will you seal the copper hammer to preserve the copper color or allow it to oxidize and eventually turn green?
Nice hammer
Thanks for sharing this insightful video. Do you ever add borax to your metal melting process.? It is used to remove impurities from metals that are being melted and refined. Wishing you a great week filled with gentle seasonally appropriate weather and restful evenings. Peace brother
Any particular reason you make the majority of your hammer heads square as opposed to rounded?
how long did this take from start to finish after you had the mold made??
What's it used for ? For beating solid copper nails !
Very cool project! I too made a copper hammer for my mini mill and I'm sure you will find your hammer fun and useful! (There is something very satisfactory in making hammers, isn't it?)
Hello! Question. Is the petrosand reusable after the casting? Can you scrap off the burnt parts and reuse it? Thank you.
Just curious do you think you could do a head bust of a famous person, both printing and casting?
What is a good flux / degasser for copper? Thanks.
Need to get yourself some starrett die cutter bandsaw blades
This is a great video, and the casting came out very nice, and I hate to nitpick, however the title list this as "solid copper" and it's simply not. That chunk of tin/antimony pewter made all the difference in how this came out.
Did you think of making that wooden 'Petrobond' casting frame out of metal 'boards' that you can just screw or bolt together? That would make for a really nice video or two, and you never have to worry about about it catching fire or making a new one. - I'm hoping you like this idea and we get to see you making it AND add some really cool design 'final- touches' :)
I definitely like the music you are using these days way better. The quality of the video overall is good as usual. Have you thought about gettting a resin printer?
He has one
Do you use flux when melting copper?
Loved the way the hammer turned out, but hate to see the line left by the two parts of the sand mold.
I have a video suggestion! How about you compare molds made with petrobond and plasture+silica sand?
Are you happy with your PM-30? Do you wish tou would have purchased a larger mill?
Is there a reason you don’t remove the line where the two 3D printed pieces came together
That came out so nice! I saw someone get rid of those print lines by covering the print in wax before taking the mold, could be an interesting experiment. Keep up the good work!
I absolutely love your channel I wish you would do videos more often
Why did you choose to use the hand file to clean up the handle and the belt sander to clean up the ends of the hammer?
what kind of forge do you use?
didn't sand the flashing on the handle?
dont you wanna pound tubes flat before smelting them as there is a chance an air bubble can get trapped and cause an explosion of sorts (explosion as a little pop but sprays hot metal around)
you can, but flattening the pipe can also cause air to be trapped in it. the only thing you really have to worry about with casting metal is your medium being wet or moist, thats what causes the explosion
please make another video about lost pla of complex object.
Schaut toll aus! Ein Handgriff aus Holz wäre mir aber lieber, da Kupfer doch leicht toxisch ist.
Stupid question: wouldn't it be better to mold the feeders onto the original mold? Seems like you would risk collapsing the edges of the sand mold while carving them less...
Can you electrify it like in the games?
you seem like a dwarf to me having fun in the forge so maybe you chould make some dwarven esc fantasy things i don't know what but it would be cool!
“I threw some peanuts into the red hot crucible” caught me off guard haha
Nice, but I still prefer that skeletonised hammer from a while back. That is an epic looking little hammer.
😊
nothing is better to start a day than watching peanuts burn
Hey try 3d printed electroplated full copper process, no melting hot temps, just electricity
Also can make metal molds with same electroplating technique
Like nickel and chromium metal molds for high temp casting
