@nprofile…g4j5 Yep. Granted it was less so welding and more filling in a hole then grinding it smooth.

Tried welding for the first time last night to fix a mistake I made on a cast I’m working on right now. I’ve got to give it to welders because it’s definitely a lot harder than YouTube makes it seem.

Shes finished! I patinated her with the same oxide colors as the statue of liberty, but kept the flame covered to give it the golden look

@nprofile…g4j5 Nope. Just a personal project thats been on the back burner for awhile now

@nprofile…g4j5 Shes around 5.5in without the cement base, but i'll happily do that one I take the finished pictures.

A few more photos from different angles

WIP of a casting I've been working on. She'll be getting a verdigris patina to properly look like the statue of liberty soon enough.

@nprofile…g4j5 You can use a propane furnace, though it will be a hassle. Burnout schedules are pretty precise, long, and go up in down in temperature. If you used a 6"x8" flask like I use, you'd need to frequently measure, adjust and run the propane for the entire 14 hour burnout. You might be able to get away with iffy to decently results without firing if you use wax for your model, but the resin doesnt burnout until 1350f and the investment needs to be fired properly so it doesnt break at the temp

@nprofile…g4j5 Vogman also has a good video on the resin. Though Siraya Tech themselves told me can avoid the mess of glycerin if it suits your work flow. Though they did also promote a blog saying you could wash off the glycerin with soapy water as long as you quickly dry it, despite saying never to put it in water. I think their instructions are for full certainty and as a hobbyist you can try stuff to see what works for you
If you do use glycerin though, keep it sealed as its very hygroscopic

@nprofile…g4j5 basically i wouldnt say its needed in my experience, but it definitely cant hurt to follow the exact directions when first starting as long as its not too much trouble.

@nprofile…g4j5 Ive tried it on and off, but didnt do it in this project and still got good results. A lot of casters online and even siraya tech themselves seem split on if its needed. Some casters and a siraya tech page say you need it to shed oxygen, but I emailed them and they said its only to help it cure faster and only needed to stop o2 absorption if you dont plan to immediately make the mold. One jeweler I trust even lists curing as not needed for it. I would recommend the ethanol over IPA tho

@nprofile…g4j5 I mix the purple and blue version of it and then then use r&r plasticast to make the mold. Not sure how it’d mix with other castable resins, but mixing with normal resin would probably ruin it

@nprofile…g4j5 it’s cheapest on Amazon right now
https://www.amazon.com/Siraya-Tech-Cast-1kg-Castable/dp/B092MZRW5T/
make sure to get the proper investment powder since resin expands while heated and will crack normal investment
It also won’t work for sand casting like lost pla or lost foam since it’s burnout temp is much higher

@nprofile…g4j5 for this cast I used a 50/50 mix of siraya tech true blue and purple castable resin. In my own experience burns out well, provides the best of both worlds between the 2, and is easily much cheaper than a lot of high end castable resins.
For FDM printing though there’s a filament called polycast which is made to burn out clean and can be smoothed with ipa to remove layer lines before the cast

you spin my mare right round right round

Solid bronze plushe crocs and a new photo box for pictures. There are imperfections, but I'm happy how these came out since it was thin wall casting practice

@nprofile…g4j5 but it just looks so tasty

@nprofile…g4j5 Kek I’m pretty lucky to have no injuries. Just a broke graphite crucible and a bit of heat damage such as a slightly melted trash can

2024-12-29 06:13:27

Just had an oopsie with my latest cast. Always a good reminder to be safe when working with metal

@nprofile…g4j5 Sand casting is fun and where I started, but I moved away from it since its not super fit for sculpture casting due to how it handles overhangs. There are some methods that ignore these problems, but they only work well with low temp metals like aluminum or zamak.
The downside of vacuum casting is you need an electric kiln to fire the investment, which gets expensive. If you do ever decide to get into it though you could probably build your own since you seem to have the tool and skills

@nprofile…g4j5 The mild vacuum created by air being pulled will pull the metal into all of the tiny details in the mold while also removing gas bubbles so you don't need venting tubes. I'll take some proper pictures next time I do a cast.
I'd also recommend checking out ceramic shell casting which isn't as detailed since it doesn't use a vacuum, but isn't limited by the size of the flask making it good for big casts. Investment is my personal favorite way to go for small ones though.

@nprofile…g4j5 Here some pictures of my (very messy) vacuum caster.
Its basically just a pot with a connection for a vacuum pump tube with a hole in the top. When the metal is ready to pour, the flask is inserted and sealed with a gasket, or as I prefer liquid silicone, where the flanges touch. The top of the flask is left open to have access to the pouring point of the mold, but the investment is slightly porous which means the vacuum tried and pull air through the it.
