- I recently bought a Precision Matthews PM-30MV milling machine so I thought it would be fun to machine a brass ingot. I cast the ingot in my homemade metal foundry using old brass plumbing fittings.

Just a few milling tipps that came to my mind:
- always look up what cut depth is recommended for your tool and material, otherwise you'll shred your tools in no time
- when you wanna set the zero point on your work piece, you can put a small piece of paper in between the cutter and the piece, lower the cutter slowly while shifting the paper a bit, until the paper gets stuck. That's your point
- when you cut anything harder than brass, like steel, use cooling liquid, or you'll burn your tools and reduce their life span
The milling machine adds a new dimension to the creativity that emanates from the fertile mind of the guy behind Robinson Foundry. As usual, well done!
I'd suggest getting in touch with This Old Tony. He's a metalworker on youtube and machining some custom casts sounds like something he'd like to do.
1000% this
hands down the most beautiful brass ingot ive ever seen in my life
Absolutely loved the "trash to shining bar" part of the whole deal.
And congratulations on the milling machine - onwards to other projects!
I did casting back in highschool and one of the favorite things I made was just a tiny aluminum cube I spent hours on with a file and sandpaper to square up and chamfer the edges to the best of my ability. This reminds me of that and makes me want to revisit it, beautiful stuff!
9 minutes ago I believed paperweights where useless. Now I need one to.... hold my manuals open. A common problem.
Wow. Shiny stone is shiny.
These bros are getting things which are can't even imagined by my mind
Since it is a representation of what the milling machine can do, I agree with leaving the milling marks on the faces. It looks amazing.
If I was casting an ingot that I wanted to be 2" x 4" x 6" I would 3d print pieces that were 2.5 x 4.5 x 6.5 to give myself plenty of material to machine off.
Seeing all the metal shavings I was taken back to my grandfathers shed. The dirt floor was inches deep in sawdust, metal shavings, nails and screws and general debris. A stark contrast to his indoor space where he repaired watches and clocks. Keep on making great things.
Looks like you have a little helper there. Or is that the supervisor? 😁🤣💖 Great video, thank you for sharing.
I admire the way you showed your entire process, including the avoidable mistake. No ego there which is great to see. Lovely result & fascinating to watch, thankyou.
pretty good finish
This was not just any run-of-the-mill video :)
so fucking glad to see an american taking the time to make the conversion to the metric system!
Congrats on the new mill! This was really satisfying to watch and I'd love to see more "castings turned into nice stock" as a regular thing
First!
lol!
Yarrrrr
Lol
well thats not really fair.
I'm in advanced manufacturing and use the tool in this video. You did a great job, keep it up.
Like the new machine, bar looks amazing 😊
That thing is gorgeous
The ingot looked amazing. That milling machine did a fanominal job!!🙂👍
One thing I will say is that you'll need to build a shroud behind your mill and if you get to the point where you need fluid then you'll definitely want something to catch the chips and fluid. Good project video?
Your doing what I did when I first started running manual machines at work. These machines can handle a lot more than you think. So you can take deeper depths of cut just got to adjust you feeds and speeds until your machine is happy. My main problem was babying the machine going to slow and to little depth of cut. This causes chatter and rubs the carbide to death. It also makes it sound like your machine is falling apart even though you aren't really doing anything pretty easily. Your not going to be doing this on your machine but at work when I have to put a flat on the bottom side of an aluminum/ bronze alloy acme pillow nut I can take a half inch depth of cut quite happily. But the machine I have to work with has probably 6 times more weight and power than your machine has or more. A lot of it comes down to the rigidity of the spindle, tool (stick out), and work holding. I am but an apprentice so I'm sure others will have more and better advice but I will leave you with a quote from my boss, "You won't know how much the tools you are using can take until you break some".
This is what I do for my ingots, it makes all the difference in appearance. It’s nice to find other people that have the same interests. Also give a fly cutter a go.
Those chamfers make that look a bit like a LEGO ingot piece
Absolutely beautiful
Oooo. I’ve been asking BigstackD to mill one of his ingots forever now.
It's so-so amazing crafts I like it very much
Beautiful, well done. I love the sound of a milling machine.
There is a whole art to making decorative tooling marks, or machining something so the toolmarks look good. I'm glad you left them. Watchmakers have a similar decoration called Geneva Stripes. Arch motorcycles programs their CNC with special attention to how the toolpath effects the finish.
Your final result is 😍
Given the size of parts I think I'll deal with I'd have cleaned up all the chunks you got, even the riders themselves.
Fantastic! Just ordered a 30MV for my studio. Glad to see your casting process.
Very cool . I remember when I got my first machine . Lots to learn even for those who’ve been machining for years like myself.
Now that you have cast and milled your first ingot are you going to collect a ton of castings similar to the horde being accumulated on the BigstackD Casting UA-cam channel. He usually posts a video every Friday.
Nice seeing your milling machine in operation. I hope it brings you years of enjoyment and income. Cheers
Dunno why but I smiled at the mention of BigStackD. Been watching his videos every week ever since I discovered his channel
I don’t think I’ve ever seen your face 🤯🤯 wow! Nice ingot and I love your vids 😉🙂🙂🙃🙃🙃
Amazing work, congratulations 👍👍
Oh dam!you got the milling machine!
That thing is sweet!
I'd suggest use copper wire on moving jaw side of vise when squaring stock. :) Nice result.
Now you need a surface grinder, then you can really take over the ingot polishing game! 😂
I think It's definitely worth spending the dough on a milling machine 👍 the ingot turned out really shiny after the pass with the milling machine 👍
This is the perfect Brass bar!
I'd really love to see the same with a copper bar. Those qre my favorit!
That's the great thing about casting. If you don't like the cast, you can just remelt it and try again.
Hey man I absolutely love your work, you make really sick castings
Please make more of this videos
Great finish by milling machine.
Beautiful work!
Nice job seth!
3d printed parts are usually too rough to make good sand molds unless you finish the surface nice and smooth. I know you use 3d printing for basically all you've shown on youtube (i think) but I do think if you are making simple things you should use wood. Plus, wood is easily biodegradable.
In addition... using wood will give you an excuse to buy a cnc router. 😉
Painting a varnish over 3d prints improve their surface. This could also work.
Wish you'd followed through with the mirror finish, but only because I'm obsessive. Great video, very satisfying to watch.
The milling machine definitely makes the surfaces smooth but the as cast surface texture is my preferred result.
Interesting to see how many skills you have, modeling, casting, 3d printing...
Great video
I would love to see a video where you talk about how much flux you use/what kind etc. Your castings always look top notch and I would like to be able to use a similar process to improve my own
you can sieve beach sand into dust and then use the petrobond oil, pretty cheap
Beautiful ingots here folks. Top notch work there. I found you and now I'm subbed! Keep it up and you will pass BigStacked!
Sand your prints than primer and paint them and it makes it easier to get them out
I enjoyed yours videos
Do a video on Penny! Where did she come from, what does she like and dislike, little things about her personality, etc
Relaxing crafting
You have the power to do what most machinists can't do. it's recycling your Chips for new material.
I think all CNC shops squeeze their chips to recover coolant and have rollaways for iron, steel, aluminum and whatever other scrap.
Just a thought in one of your videos i just watched, which was the Copper Hammer if you put a piece of cardboard down on the fire brick the crucible won’t stick
very nice mate .
Something I would love to see is a shaving catcher of some sort. Maybe after a while we can see those shavings be turned into something🤔. Anyways congrats on the new mill
hey good idea man =) I saw someone use a bunch of different kinds of metal chips mixed with clear epoxy make some amazing things, it was a reeeeaaally cool look
since you are new to milling to get a better finish, 4 flute end mills are for hard materials like steel. For soft materials like brass, aluminium and plastics use a 2 flute end mill. the difference is night and day.
You need to make your mold larger than the intended final dimensions. Figure out exactly what metal or alloy you have, then look up it's thermal expansion, and then make the mold that % larger based on what temperature you will heat it too. You can also reduce some thermal expansion by heating it exactly to it's melting temperature but this can cause the mold to clog before it's full.
very nice
You should make custom made putters
Nice!
Did you add a draft angle on the 3D printed patterns to enable them to be removed from the sandmould easier?
Great work on the trash to treasure ingot love the new machine. You should do a cast for the new Jurassic Park movie. Maybe the logo in copper or bronze like in the trailer?
I enjoy your videos and have been impressed with your work. Out of curiosity does your milling machine have power feeds? It is hard to tell looking at the video when you speed up the frame rates. If you don't have power feeds you might look at adding them in the future. The quality and performance of your maching depends on keeping the right feed rates, which depend on the depth of cut, speed ot the cutter, and the feed rate of the material into the cutter. Going from bronze to something like stainless makes a world of difference.
Many years ago they could not machine the Chevy Vega aluminum blocks. A combination of wrong cutters, wrong feed rates, wrong rotational speeds stopped the machines from milling the engine blocks. They paid a lot to a consultant to be told why machines weren't working.

5:30 Inspector Doggo says it looks pretty good.
Approximately how long will it take for a noticeable oxide layer to form on the ingot?
Can you identify the alloy, find the density, and then measure the volume of your ingot to determine if there are internal voids?
Yes
So how was the very first mill made without a mill
I assume its minimal as possible but what %infill do you use for doing lost pla casting?
Is lost pla method suitable for stainless steel casting?
did you put anything on to protect it after?
You should look up you feeds and speeds if you haven’t already.
I want a mill machine now
You should create sustain blocks for Tremolo guitars (Floyd Rose)
Would you do the same thing with the copper and aluminium, please
Would removing the corrosion from the brass fittings help appreciably with removing the impurities?
Maybe a little, but I think most of that stuff just ends up sludge that you can scrape off the top of the metal before you pour it.
Maybe a high polish brass ingot but stamped as gold.
I'd take a look at the tormac TTS system, it's alot of money but those R8 collets for tool changes are super frustrating having to touch off your z axis all the time, also take a look at practical Renaissance yt channel, he did a power drawbar conversion, that in my opinion is totally worth your time to do , cheers !
Crazy
I dont know why but I want it.
Awesome result as always, are you planning to collect metal ingots? It would be cool shiny collections
You should've hit the brass bar after setting it in the vise. Not extremly hard, just hit it once or tap with hammer few times.
(No idea why people do that, but A lot of people, including my teachers say that its needed.)
"Most of the large metal parts of this mill were cast and carefully machined"
"I used the -stones- *mill* to -destroy- *create* the -stones- *mill* "
Gud vid
Do you put flux on your brass
Why was this petrobond black at 1:56? Was it used multiple times?
Fuking awesome. How accurate is the precision Mathew’s milling machine?
It is as accurate as the person using it. No machine will give you more accuracy than you give it.
With proper set-up and proper usage, this mill can give you accuracy down to about +/- 0.0002”(ish)
it does have something that unpolished
looks tough like this
What a fun idea! And the end result was beautiful! What bronze alloy is this?
It's brass so copper and zinc
@@nothingnothing1799 d'oh! I'm bad at reading. Thanks.
Ok but, where did you get those boots?
6:54 anyone hear bagpipes coming from the mill?
Can you cast Soldier Boy's shield? (From the TV show The Boys, if you don't know what I'm talkign about)
I don’t know if you considered selling machined ingots? I guess if I’m asking it means I’m interested if the price is not too $$$ I’d be interested in a copper ingot.
I’m a machinist!
Can we have a VOD for UA-cam please?? 🙏🙏
