How to Cast Bronze by Lost Wax, S2-E56

[@thomasarussellsr]

Cool visit to the college. Thanks for taking us along, and thanks to the college for having us for a video visit. Loved the host's and his students' art work/sculptures.

I grew up in the 60s and back then, boys (sorry that’s just the way it was), had manual arts classes. Metal working, including casting was part of it. This needs to come back to our k-12 education so we can develop more Bob AND Barbara Emsers.

[@TheArtofBoatBuilding]

Hi Matthew, I couldn't agree more. Back in my day it was called Industrial Arts. The skills I learned back in the last sixty's I call on almost daily. Thanks for watching! Cheers, Bob

@@TheArtofBoatBuilding Hi Bob, so cool that you replied. Yes, it was “industrial” arts, thanks for jogging my memory. My 3 sons and daughter have all eventually picked up from me woodworking, construction and general DIY activities . What you are teaching the world with your videos is incredible. However, looking back at the jewelry boxes, spice racks, chess boards etc etc that we had to make in school shop class with our own hands were such indispensable lessons. Honestly my kids were a little shy around my tools until after they were grown. Happily they saw what I did and came back to it on their own. BTW we had met a few years back at the Mystic Wooden Boat Show (my boys were with me). Love your work, especially the tools you’ve made.

Great episode Bob. Thanks for sharing!

[@michaelc.3812]

Bob, your videos are terrific, and I only wish they were more frequent.

[@dwaynekoblitz6032]

Those left handed threads have saved countless lives. I'm so anxious to watch you actually making the molds and pouring the bronze. I'm seriously looking forward to it!!

[@jamesbain2791]

Always a joy to discovery a new video from Bob and the Art of Boat Building!

[@JenkinsBoatWorks]

always learn something Bob.. Thanks, Chuck

[@Rsama60]

Can’t wait for the next steps.

[@MCsCreations]

Pretty impressive, Bob! 😃 That's a fantastic process! Thanks for sharing!!! Stay safe there with your family! 🖖😊

[@tomtruesdale6901]

Very good lesson on casting. Looking forward to your casting of the parts

[@cerberus333dog]

I really enjoyed this. Thanks!

[@TheArtofBoatBuilding]

Hi Perry, Glad you enjoyed it! Thanks for watching. Cheers, Bob

I did several semesters of Bronze Casting over 20 years ago in my college Art Dept. Our equipment wasn't nearly as sophisticated as that nice set up that Bradley U. has, I'm def jealous of those students, lol! Our foundry was in an outdoor yard behind the Art Studios, we did have an I-beam sort of pergola over the area and it supported our small rolling crane for the crucible. We did pours in the dead of winter and man was that furnace heat great, while the snow was flying we only wore regular shirts under the safety leathers and never got cold. The one thing I noticed the most in this video was the molds, they used a ceramic slurry with sand in multiple coats. We were much more 'old school', we poured plaster/sand molds around our wax copies and those had to fired in the ceramics kiln. Our huge molds were a lot heavier, used more material and generated far more waste.

[@TheArtofBoatBuilding]

Hi Luke, Great casting memories. Bradley does have a great foundry setup. The small school I taught at was much like your experience of doing plaster/sand molds. They where heavy molds. The up side is it was much easier to clean off the investment unlike ceramic shell which is very hard. Can hardly wait to get some patterns made and start casting. Thanks for watching and sharing your foundry experience. Cheers, Bob

[@bendriggs]

Great videos! I'm amazed to find out you're in Eureka and taking a field trip to Bradley.. I grew up in Tremont. I found this series as I was looking for tong and shank designs and kept watching because the videos are so good.

[@The1stKukuDrifter]

My nephew goes to Bradley. Was cool to see his campus. 😃

[@mattevans-koch9353]

As always an excellent video Bob. Enjoyed seeing the casting at the University and looking forward to seeing you do your castings. Take care, stay well and have a great week ahead.

[@stujd1539]

Did you leave a can opener for the guy you parked in front of so they could get out?

[@TheArtofBoatBuilding]

LOL. There was more room that it looks on the video. I did look to see that there was plenty of space behind so that He/She could get out ok. Cheers, Bob

[@andyhastings5950]

Great episode.

[@steveschwartz6138]

You make it look easy. Very interesting video.

[@mickfisch96]

Thanks Bob. Very informative and interesting to watch.

[@TheArtofBoatBuilding]

Glad you enjoyed it

[@pcahill10]

Another great video, Bob. Can't wait to see your castings.

[@MaShcode]

So you’ll be using the same lost wax method? Apologies if I missed any mention of your casting plan. You got a nice mention in the last Arabella episode.

[@TheArtofBoatBuilding]

I'll be doing sand casting. Cheers, Bob

[@MaShcode]

@@TheArtofBoatBuilding had a hunch 🤫

[@drop_dtuned6167]

Oh ya, first lighting of the furnace. Loved hearing that distinctive growl and how it changed as you dialled in the burner. Similar to the changing pitch when putting new strings on a guitar.

[@garyfroeschner2523]

good stuff

[@bitengoleg2653]

Красивое видео Я тоже это проходил для своей лодки

[@TheArtofBoatBuilding]

Спасибо. Спасибо за просмотр. ваше здоровье Bob

[@markbrinton6815]

I'm surprised you don't use a blower on the furnace. The propane pressure just out of the tank is sufficient? Every setup I used before had "forced air" .

[@TheArtofBoatBuilding]

I do have a regulator on my tanks. Propane burners don’t require a blower. In fact they won’t work with one. All for my earlier burner’s were natural gas that had blowers. Thanks for watching.

[@markbrinton6815]

@@TheArtofBoatBuilding THANKS!

[@shanek6582]

What would I look for to buy a propane regulator like that? I’ve got a huge bbq grill and I can’t find a regulator that’ll put out enough psi for all the burners, that looks like my remedy.

[@TheArtofBoatBuilding]

Hi Shane, I bought my gauge from Devils Forge. Hope that work for you. Cheers

[@petterandersson7429]

Nice field trip 👌 So I'm curious if your going to model from wood or wax or maybe even 3D printing!

[@BrunoWiebelt]

hi , I propose to test the crucible for cracks by taking it out when it is max temp and burn a page of newspaper in it . if there are cracks you see it as small lines nice video . all brons is SICu or 10% TNCu?

[@thomasnewton9818]

Thank you for your videos on casting bronze. It can be difficult to find information on the process. Your equipment looks great. Will you have any problems with loss of pressure with the small propane tank?

[@TheArtofBoatBuilding]

Hi Thomas, As you may know propane tank pressure can change depending on the amount of fuel in the tank. That is why having a pressure valve is important. It will keep the pressure constant. I’ll have several tanks ready if it runs out. Great question and thanks for watching.

[@christianrogers2361]

It appears Fisher has visited Sloss Furnaces in Birmingham.

[@fisherstolz5114]

Yes, I have been to several conferences at Sloss

[@Mike-h1k]

40 pounds.I wish I could go to the local college and grab 40 pounds of bronze.Wonder how much that cost?

[@TheArtofBoatBuilding]

The current cost of bronze in my area is $6.50 per pound. Thanks for watching!

[@barneygoogle4003]

Casting looks very dangerous. One mistake is too many. My guess is there are a lot of people with scars from a lapse of caution?

[@TheArtofBoatBuilding]

Indeed! Always worries me being other channels I see are not taking the proper precautions. Thanks for watching. Cheers, Bob
