You have a really nice process going. Your videos are really nice and informative. They also remind me of when we were doing bronze casting with my father (he was pouring sculptures but it is the same as a process) and i feel both sad and nice at the same time while watching you work. Thank you!
I am never bored of seeing the process of mold casting. Fascinating each time, and eahc time is a lesson Do you teach these techniques to people in real life ?
Have you ever considered building the ingate and a "boss" to hold the sprue pipe, to your printed patterns (provided there's room on the print bed, of course)? It might simplify the process of ramming up the mold. No more having to cut the ingate, and something more rigid to hold the pipe you use to make the sprue.
I do actually do this on patterns if I need to make a lot of them. Here is one example. ruclips.net/video/gtMxhDlLKsc/видео.html More on this one ruclips.net/video/sIBQWh-1eYk/видео.html
Do you recommend this mold/liquid metal pouring technique to mold something like the sheet metal of a car door? is it even possible to use this method for something as thin as a car door??
I've noticed that you don't seem to vent your molds like I learned in the Gingery books. He had you stick a thin wire through the sand in a few places after you removed the pattern, to prevent steam build-up. Do you ever have a problem with that?
I always get a little nervous when I see 3D printed parts that are designed to fit together, personally I've always had trouble to get parts to fit. Anyway I thought the answer to "I'm off" was "I wondered what that smell was."
Even if it costs more doing it yourself, learning/perfecting new skills is often worth more than any amount of time or money you would save by sending it off to be done elsewhere.
See you are still using blue tape on the printer. Maybe try an Ikea mirror tile and watered down pva glue? It's what I use on mine with great results. Damp sponge to refresh the pva every so often.
you're getting some really nice castings...that 3d printer is going to get a work out when you come up with more things to make. I can't help but feel you're thinking "oh man, this would have been SO nice to have when I was making my steam engine" haha I haven't cast anything for a while, going to have to get back into it. I don't have a source locally for small quantities of green sand and my kitty litter stuff just isn't that good.....
Are you planning on doing any further machining to this clamp? Installing an acme threaded rod with a foot on one end and a turn bar on the other? Or is this the final product?
That would have to be Tungsten. No, the man is actually an accomplished guitar craftsman who was the first person to officially make a production 5 string bass. Here he is making an acrylic guitar.... ruclips.net/video/G-tWnPAXOTQ/видео.html
I was wondering if you did any sanding or filling on that pattern before you cast it? If not, do the layer lines give you any trouble? What draft do you normaly use? Love your videos. You may enjoy the excercise you get on the hacksaw, but I was able to pick up an old 3 wheel bandsaw at a junk store for $45 USD, I had to redo the drive and purchased some pulleys (which you could easily make) and I have about $100 in it now, and I always wondered how I got by without it. A real timesaver. They may be more rare where you are, though. Take care.
I just sanded the edges a little on this one. I have added filler on some of the larger ones as the vertical surfaces need to be smooth. I usualy add about 2 deg draft. More on the edges that are machined. I have a bandsaw but not a problem sawing of the gating. On most occasions you would not be able to get the casting and gate lined up to saw it off.
Okay, the title of your video got my interest, and, of course, I enjoy all your backyard casting videos. However, I am still mystified about what a guitar bridge clamp is. Does it actually have anything to do with guitar bridges (I know what those are)? Or is it just a name? Showing a few other castings you had done earlier doesn't elucidate things at all!
The casting will be made into a long G clamp. It is used to clamp a guitar bridge in place when making the instrument. A google search for guitar bridge clamp will show you what they are.
Your videos are a constant source of education and inspiration. Thank you so much!
Very nice video. What kind of gloves do you have? Where did you get them and for how much please. Everything I have purchased melt.
They are just regular welding gloves.

Thanks for showing how you dealt with sand that was a bit wet.

No I don't do teaching!

A great specialist in casting
Nice job.
I've always been curious how and where you learned all these skills, its very impressive
Just self taught from books.
What is the name of the aluminum that contains the most silicon?
Do you recommend this mold/liquid metal pouring technique to mold
something like the sheet metal of a car door? is it even possible to use
this method for something as thin as a car door??
You won't be able to cast something that thin unless it's really tiny.
Very good

I only vent cores. I have not found it necessary to add numerous vent like some show.

You make it look so easy! Nice!!
I'm curious how much cheaper is doing all of this by hand compared to sending a bulk load of plans to a mill to have it done for you?
The cost does come into it. This my hobby and I like making things.
Even if it costs more doing it yourself, learning/perfecting new skills is often worth more than any amount of time or money you would save by sending it off to be done elsewhere.
Very nice job, as usual!!

I wanted to know how much sodium carbonate to put when melting aluminum
It's not critical, I add about a teaspoon full.

That's how they will be finished but I made these for a friend and he will be machining them.
What is the purpose of the cross piece which is cut out? To prevent distortion during cooling?
It forms part of the casting by adding some sections under the main part. Also it gives a rirer to feed metal into the mould as it cools.
bravo ben fatto complimenti 👍👍👍👍
Suddenly I am reminded of a gentleman who wanted to create solid cast aluminum guitars.
I wonder if he ever succeeded.
An instrument for playing heavy metal?
That would have to be Tungsten.
No, the man is actually an accomplished guitar craftsman who was the first person to officially make a production 5 string bass.
Here he is making an acrylic guitar.... ruclips.net/video/G-tWnPAXOTQ/видео.html
He has also played and composed music for decades... www.allmusic.com/artist/philip-nestor-mn0000397914
His contribution to the group Gryphon en.wikipedia.org/wiki/Gryphon_(band)
Deep throat clamps for gluing bridges on acoustics.
Have you ever tried to cast with 3d-printed parts just like people cast lost foam?(some kind of lost ABS or something like that)
There is wax filament for this purpose.
Yes I have tried it but have not had anything to cast since that needed it. Video here ruclips.net/video/kgakfi8Ibjc/видео.html
I seem to understand these are used in building a guitar. Do you build guitars in addition to the other awesome stuff you do?
I don't make guitars ( or play them! ) these are for a friend.

Jesteś SUPER! pozdrowienia z Polski.
What density had the pattern at 3D printer cam? You use Cura?
IDMA 95 depending on your printer bridging ability. The percentage infill is to support the start of the top wall thickness. Looks like 15 or 20%.
I use Cura, I don't recall exactly it would be about 15% infill.
Nice mutant horse shoes lol cool project
I've seen people put the talk in a cotton shirt and puff the talk on, Is there a reason why you apply it liberally like that?
I find it easier like this, just it straight from the talc bottle.
What do they actually do?
They will become clamps to hold a guitar bridge in place during the building.

I bet you’ve got a whole room full of those patterns.
I’m guessing your whole life was being a machinist?
No casting and machining is just my hobby. Lifetime work as electrician.
ok, saw this 75th time now
p p Same for me, and I continue to enjoy it.
