Sodium Silica Sand Casting Rocks! * Fewer Failures * Faster Results * Bigger Castings * Less Equipment * No storage Resources: Foundry Practices http://movingimage.nls.uk/film/1529 Building a Furnace https://youtu.be/f10hqYGIJCE More Furnaces: http://svseeker.com/casting_furnaces.htm Building a Burner https://youtu.be/P-A8uoWdBB8 Casting Propellers: http://svseeker.com/casting_boat_props.htm OMG! Wear a respirator! Glass Micro Balloons will Destroy Your Lungs" and Other Myths: "In the case of GMBs the increased persistence, when sequestered in the epithelium did not result in any additional reaction to the particles. This is consistent with the known properties of these glasses which generally show little or no tissue reaction. A survey of 46 workers exposed to GMBs also showed no evidence for an effect on lung function or on increased prevalence of respiratory symptoms (I. P. Tarns—personal communication). Thus the retention of small numbers of GMBs for extended periods in the lung tissue is without demonstrable effect in rats or humans. The consequences for similar retention of a more reactive particle are unknown, but may be less benign." http://annhyg.oxfordjournals.org/content/41/inhaled_particles_VIII/588.full.pdf
This was very much appreciated! Great tutorial on how to make a successful cast! Most regards from sweden
For fine detail castings Dust your parts with a powder coat'r charge the particles, I find best results with Silica dust collected form Burning Man festival.
I see someone else realizes that homemade degassing/fluxing are a waste of time
I love to see that you have been learning from your mistakes, I remember when started to pour brass! I remember your mistakes.. but I have to say that the fact that you managed to find "Simple Yet Effective Solutions" for those problems!! That is golden my friend.. Please know that I do have been doing casting on a very, very smaller scale. and I have serious plans to use a few of your ideas!! wish you the best in your endeavors sir!.
great video, learned a lot again. Nice to see and hear all your experience on casting in one episode. Cheers.
Great video. Enjoyed the thorough explanation of the different steps in the process. Keep up the good work.
Another Churchill quote, "If you're going through hell, keep going!"
This was the first video of yours that I've come across.... and I watched the entire thing haha. You kept the knowledge coming the entire time man. Thank you.
Same ways. You've got an excellent channel yourself good sir.
I've watched some of the older videos starting maybe 6 years ago or more as was really inspirational when I lived on the Kalamazoo River since was researching building a steel or aluminum (titanium would be interesting though never verified materials performance and cost seemed unreasonable) electric hybrid jet boat with solar cells on the surface. I was also toying the idea of integrating into a larger sailboat catamaran or with jet boat motor room center hoist boom crane idea pod trimaran. I did get around to experimenting with using a 1000W gas generator with a computer power supply modified with higher current fuse and terminals as well as wiring and used with a trolling motor with the canoe and I think I used on the John Boat that was stolen prior too. Never got around to making a transom with the kayak, though did invest in a windsurf board to keep the project going. I was also looking into external combustion sterling engines since work better with more heat exchange potential and under higher pressure (maybe better for submarine or trench thermal vent power stations or maybe on some kind of high temperature volcanic tap desalination mine operations system). Well, I wound up being armed robbed and shot while watching a ferro-cement project since was looking into other systems like concrete ice breaker potential projects along with the water cistern and bio-gas generators (ICP/ARC Furnance and fermentation) I was looking into making on the hillside. Lately, I've been looking into and making rocket stoves and want to make a sodium/calcium/magnesium silica aluminum oxide sand with a titanium oxide liner. I was also thinking about adding a graphite liner too to store more heat on the outside and maybe prevent corrosion deeper. I have the materials and way more higher level enforcement now since I had to learn some far out ES/TS EW weapons systems worse than the Cuban Embassy U.S. Diplomats et.al. issues to determine what was targeting me in the first place. Excellent videos!
I agree. Well worth the time to watch the entire video. The portion about the riser and the quality explanation about that was awesome!
Easy way to make CO2: baking soda and vinegar.
That Vid was a beauty Doug you explained the process clearly and concisely enough taht anyone thinking of making their own castings could do it too.
My grampa was a foundryman in Glasgow I fancy giving it ago and you're video's are an inspiration so 2016 time to make cast a project or two.
+ryzo mcgregor Rock on.
Brings back memories back 40 years ago when i worked in a Foundries core room making sand cores for many things ,fire hydrant tops and hand Pitcher Pumps, gutter pipes .Thanks for the video.keep up the good work.
Great job Doug, Cant wait to get back out there.
And looking forward to the lead keel pour.
Nice how-to.. you have really come a long way on the boat.. I can only imagine the self-satisfaction you have seeing your dreams come to reality.. congrats.. i'd like to see her one day.. maybe I can swing by next time i'm up that way..
Dog walking around like "I'm helping!"
Doing the extremely important job of providing moral support, of course!
I'd like to know a bit about Jack. I guess he lives close by? Is he an old friend or also somebody you learned to know through the SVSeeker build? Retired?
+larsmark Jack is friend and crew, and native Oklahoman. And always near when we need a strong back. :)
+SV Seeker Haha, its lovely with such friends ☺
Skillfully done, very educational for the people who want to get into the casting process.
Perfect explanation best i have learned from yet. Thank You so so much.
Mate, great tutorial.
Finally someone that can speak in a plain language. And keep it simple and to the point. thanks for not over complicating the crap out of this. Btw. nice peace of casting, looks good.
exactly. genius is accidental, not overcomplicated and draining. that was a breeze and a sweet token/momento ending
Cheers, that was pleasantly cathartic to watch. I did some sand casting of Ally when I was in school. One the I picked up on as an engineer myself, that identified that you're a good teacher and not an A' hole, is the fact that you readily credited the foundries from where you got various tips. Which shows a lack of Ego. Too often I've worked with, and experienced 'Experts', that talk down to you, like they were born with this sacred knowledge. Which always annoys the crap outta me. Your no bullshit approach, bought a subscriber. 👍🏻
Hey thanks for the video ( the K Thermal coupler ) was exactly what i needed to see . Think ill head out to the shop this week and look at making one . Keep the Videos coming !!!!
Never done Casting by myself befor, just collecting information about it :)
Thanks for this Video from Germany
Enjoyed this vid, keep up the great work inspired me to build my own backyard foundry...
Thanks I was wondering where I could get a step by step guide
Totally entertaining video... and I learned something too. Thank you for sharing your work with us.
Maybe it's an okie thing but I'm the same way. The easiest way is the best... usually.
Great tutorial on the home foundry. The safety nannies must just love you.
Keep on rocking in the free world....
Bruce from Canada
+MrPlusses Thanks. I think most of the safety nannies have given up on me. :)
awesome to see! good luck! hope to see more vids!
I look forward to every vid Doug! You make my day Sir.
I love what your doing. I hope someday to make it out to give you a hand. I am kinda a jack of all trades master of none. Keep up the good work.
wow great video! thank you for giving me some understanding of the mechanics that goes into an amazing proses. I have defiantly learned something today
I enjoyed that, cheers.
Thanks Doug. Reminds me of one of my favorites "No hill too big for a stepper". Probably because thats me.
Stepper
Bravo my friend, bravo!
Thank you for the safety tips and explaining everything you were doing! I learned more from this single video than any other I found.
That video was totally awesome! Iam really interested in making my own castings! Thanks for sharing!
Thx, walking us though the process!
Fun to see the hole casting process :)
Great step by step explanation!! i see this little cute pulley at the beginning easily casted with sand and a donut shaped core :-) no need for wax!
+Pierre-Yves Puech A core would work but I'd have to change the pattern some. The real goal is to get the process down for lost wax with NiBrAl.
nicely done!!!
When you play with the investment casting if you do your first dip then put the tree in a vacuum vessel and pull a vacuum you will pop the little bubbles that naturally form on the surface of the wax giving you a fantastic surface that in many cases will not need any machining. Just a little trick we used to get high definition back in the day
Love watching the Videos, please keep them coming!
+Marc wire Thanks for the tip.
Marc wire uui
I don't know why but i find this so interesting! Irs amazing how perfect it turned out!
I must admit that I indeed learned something today from this! This was truly excellent! \(^_^)/
That was a great how to video on casting.
I have learned so much watching your videos. I would love to come out and help you while learning more. Just one thing, I would never leave.
Great inspirational video thank you Doug!
I remember reading about microspheres falling out of favor because of the havoc they cause when reaching the ocean. They were used in cosmetic products.
I use a 110v hot water heater element right in the Used engine oil to pre-heat the oil worked great.
Cool! The narration was great - appreciate that!
Jim@MidOhio
One of the most informational casting videos I've seen. Very thorough, thank you!

That was a fantastic instructional video.
Thanks.....going to "favorite" this one for future reference.
