Casting fluted bronze bells 

and that is all that maters 😄

And it sounds like the caster is a blessed man!!!

@@dannywilsher4165 No doubt about it 😄

Thanks Everett, that means a lot. Glad you enjoyed it.

Thanks mate

Yeah, I'm still lurking out here. I see your live streams but they're past my bedtime 😄😄 Hope the new house is working out well.

Thanks 😄

Well chalk it up to messing up the first one. If I had made the correct alloy the first time around there would have been no comparison 😄

Congratulations! 😄 Thanks for letting me know.

She’s not alone. Most people watch to see the metal poured

Thanks bud, I think it was easier than drilling and tapping... I think 😄

Thanks for letting me know.

Thanks Mark. I had another person tell me the first one sounded more like a ship's bell and thought it sounded better. After listening again, I see that.

They say adding a little silver to the alloy helps the sound too. Of course I have no idea what sort of percentage of silver to add 😄

Well, experimenting if part of the game... and fun.

Thanks!

Thanks 😄

Thanks James

My pleasure. I was hoping to meet Professor Campbell this fall but it looks like my trip to the UK is off. It would have been great to meet him face to face.

Thanks bud

Thanks brother

With a name like that (John Campbell) metal casting ought to be part of your DNA 😄 I appreciate the comments, thank you. Casting cymbals seems to be a pretty ambitious goal. I have no idea how I'd get the metal to flow that far given the thinness. Best of luck with that. Always happy to chat if you have questions or just want to float an idea.

DOnt they use metal spinning for that ? Sounds alot easier to amke that shape out of sheet metal disc than to cast it.You could cast i thicker and machine it-still too much time consuming compared to metal spinning.

@@zumbazumba1 I think spin casting is the only way you could do it. I would guess the molds have to be pretty hot as well. This video kinda confirms the sheet metal approach ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4SmZsFZTeIQ.html

@@swdweeb Yeah, so if cymbals are B8 they usually make them out of sheet, but B20 doesn't work well into sheet. B20 cymbals are usually cast into a rough sort of puck shape, hot rolled out like a pizza, then bell pressed, hammered, and lathed. I'd like to attempt casting it as thin as I can manage and then lathing down from there. I'm aware that it will be a large challenge and start with lots of failure. But I'm a chemist and the idea being able to experiment with the sonic differences of bronze alloys is too interesting to me not to try. :)

@@tylerjohncampbell3846 It'll be an interesting experiment. I'd love to see how you progress.

Thanks brother

Yours is getting closer. The canon molds were fired over the weekend... maybe next weekend if I can get them back. Keep your fingers crossed 😄

@@swdweeb I'll do! I just hope it sounds good!

Thanks Richard. Yeah, answering comments makes me realize I missed being away

Second watch trying to emulate your set up. I'll never be a brilliant forger but practicing every weekend. Hopefully practice makes me a little better.

I’ve been at it, just not making videos of stuff. Working through decisions on where to head and what to show on the channel.

Didn't want to think I was ignoring you. I started to watch your video from back in August "J.A.M. 13: First Attempt at Sand Casting (This is The Way)" and saw my channel come up in your notebook. I was afraid to see what you said so I stopped. 😄 Actually I got pulled away and just now got back to it but the getting scared story sounded better 😄. Thanks for all the mentions and links in your videos. I really do appreciate it.

@@swdweeb well thank you Sir! I have loved your videos since I first found them through Paul's Garage, and I have watched through everything and taken notes, I have the book by Professor John Campbell on its way (hopefully), and I repeatedly come back to them as a form of motivation as I learn to cast. I am extremely grateful to you for what you've taught through your videos, and your sense of humor keeps me laughing.

Thank you sir! 😄

Thanks David

Clearly you don’t follow me on Instagram cap’n 😂. instagram.com/p/CbTP1dNOyPX/

Thanks Dustin

The walls are pretty thin and uniform so shrinkage wouldn’t really be noticeable but I’m always just happy to see them fill completely 😄

spasibo tovarisch 😄

Bell casting is the coolest. You'll get hooked immediately

@@swdweeb im sure i will!! I was hesitant to start casting for just that reason! Lol.

Thanks for coming by and thanks for letting me know BigD sent you. 😄

😄 Thanks

Thanks, and thanks for letting me know he sent you

Yeah, it makes a huge difference. Here's another example of a "wrong" alloy ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LO9j4KodTsE.html

Hey Oliver, yes it has been a long time. You're the second person to make that tinny observation 😄 Take care

Thank you and thanks for letting me know he sent you

Thanks!

Absolutely 😄

Thank you sir

Just been reading that the clappers are supposed to be a certain percentage of the bell weight... who knew. From what I've seen they really should be poured by design. So much to learn

@@swdweeb Wow! Who knew. I figured it was just a rod with a bulge in it.

@@alanbabcock1438 So did I until I found a DOD spec on how to make them

Cool idea. I've been thinking along the lines of modifying my table and never thought about modifying the flask. Thanks!

Thanks Greg. Just out of curiosity gave you seen this playlist? ru-vid.com/group/PLU1QP34Dv8Y70lJsPZDGnnW2n0A_fhF0w

I hadn't seen them, at least I didn't know them by that name. You're right, they are very similar. Thanks, you too

I did make my own alloy. That probably means that 80/20 is an approximation. 😄 I am using a "flux" and a new process for making my bronze. I should probably open myself to piles of criticism and show what I'm doing in a video.

I've heard the same thing that bell metal and gun metal are similar. Canons are pretty thick so maybe not much ringing but you're right ear ringing would have probably drown any canon ringing out 😄

I've actually heard that before. Makes sense that they'd be similar. Thanks for sharing this.

there's also a B8 bronze for cymbals but those are generally lower quality cymbals. 8% tin This alloy evidently is easier to work (hammer and shape) where the B20 is more brittle

Man, you're never happy 😄 If you look quick at the beginning when I'm waving the plastic pattern around you can see inside that there is a hole drilled at the top. I just stuck the threaded part of the eye bolt in the hole so the "eye" part would be in sand of the core. It's hard to show ramming harder when it looks very similar to ramming lighter on video. The second bell core wasn't all that great either. but I didn't record any of the ramming process on the second one. Most people only care about seeing metal come out of the crucible, then they want to see if the mold filled. After that, there's really only a handful that care about all of the set up. Yes I cast the brackets as well. I do have video of the first one. I think the clapper is also in there. I'll have to see. Given that I was holding it where it will get bolted to the hanger I doubt that they will sound any different hung. In fact the first bell sounds the same hung and held.

I must be your biggest fan then because I already watched this video twice (after my bedtime 🌙). And I expect I'll watch it a few more times, it really is that good. The bell pattern is exquisite! Thank you for the extra explanation. I'm going add another request, I'd love to see more about your source metal and alloy concocting process. Don't even get me started about the price of tin!!! Thanks for everything you are doing. Cheers Greg

I'm alive and well, just wasnt posting any videos. 😄

Back at ya 😄

yeah, the reports of my demise were greatly exaggerated 😄

Yep. A lot of the release comes from the pattern prep. This one was pretty smooth on the inside but not like glass. As a result it wants to grab sand as it is being lifted.

Yes and like most of my videos it's a smash hit, generating six views per hour 🤣🤣

@@swdweeb 6!? Thats not good. We must make a plan.

@@frikkiesmit327 It is what it is. There is simply very little demand on RU-vid for what I do. Its no big deal, I don't do it for the money :-D

First of all, congratulations on casting bells! One thing I've done is to make ingots with the copper/tin alloy and then remelt the ingots to cast the bell. I've seen the same problem of not getting it mixed well and this has helped me. I try not to stir the metal in the crucible but some gentle stirring is often times necessary. You just don't want to introduce a bunch of air into the metal. The other thing I do is put the tin in with a small amount of copper. The tin will melt almost immediately and the copper will take longer. Once the copper has melted you can start adding more copper to that puddle. Finally, and this has nothing to do with what you asked, I've started heating the crucible empty. Get it good and hot before adding any metal. This will really reduce the time the metal sits and oxidizes in the flame. If you can, and this is going to sound weird, add a little borax and a small piece of broken glass to the metal early on. The borax and glass will melt and form a glassy goo on the top of the metal. The goo will also reduce the oxidation. You can simple add new copper through the goo. It will sink below while the goo stays on top. When you're ready to pour clean the goo out just like you're cleaning dross.

Thanks a lot! I think I can profit very much from your answer... I already used the leftover material from the last pour, but it wasn't quite enough so I had to mix some additional copper and tin to it... But I just realized, that I always start with a fully filled crucible, and that maybe is the real issue... there is always a big unmelted clonk of copper at the bottom, that needs to be stirred quite hard in order to loose up... I will also try the borax-glass-method. So far I had a great experience following your tips and tricks, so I am really sure that wont hurt. thanks again!@@swdweeb

Thanks Ron. I did get your email and the pictures. I thought I replied, if I didn't, I apologize. I'll go look now.

Thanks. No I haven't

@@swdweeb Maybe a future video project? I'm trying to find out the shrinkage rate compared to aluminum bronze. 😉

I have not. I've never printed with any filament except PLA and I've never done sintering. Not sure how I would apply the pressure involved with sintering

I use Designspark mechanical

I do, but to be honest I just designed mine to something that "felt" right. My spin/surge trap is 34mm in diameter and is attached to a runner that is 8mm x ~8mm. (the runner is tapered for easily removal from the sand.)

DesignSpark Mechanical

Woohoo!

You beat me by 4 seconds lol!

Ha 😂 Thanks

Ha! Chuck Berry wrote a song about me 😄

Saltwater, great name 😄. I dont think I’m done, just needed some time away. There may be a #short coming out in a couple of weeks I’ve got it shot, just need to edit it

@@swdweeb if nothing else you can always show work you doing on the car 👍

@@martijamesn well... to be honest, I'd have to show work being done on the car. I'm paying a neighbor who is a mechanic to finish it and get it running. It got to the point where a lot of it was over my head. I hope to be driving it by spring... we'll see.
