Sir, This was a fantastic video. Thank you so much for the humility you showed in not editing out your mistakes; it makes the whole process so much more authentic and relatable. You also had some excellent ideas, such as the tip about using a sand positive to align both halves - which was inspired. Please keep sharing your work.

So many steps and such patience! Good job! :)

I actually had to make a note to myself that I posted next to my flask on those first dozen or so pours, "Cut the damn gates." Even so, I eventually 3D printed some thin rectangles. I can't use them on every pour, due to shape restrictions, but just having that visual reminder helps me a ton. It's amazing how often I skip steps in my excitement when something turns out really well with the rammed sand pattern, which then gets wasted because the metal has zero chance to get to the mold. It's sort of like that issue I often had in math class when I would drop the negative sign, or forget to carry the one, in those big, long, multistep problems. 😉

I really really like your videos. You are an excellent teacher!

Paste wax and a vpa. Vinal parting agent work real good

Kudos for video work! I couldn't fathom doing both my work & make a video, it's enough just to do my work! Expert multitasker! Thanks

Nice 👍

When i checked the content of your channel and compared to the number of subscribers it is so obvious how stupid human population is day to day... At least you have one more subscriber here. Thanks!

Great job of hanging into the finish. My trade was a dental lab tech. I did the lost wax tech many times weekly. I do believe it could be done in this application faster and with perdictable results. I feel too old for this game now. Good LUCK!

Agree, fiberglass is not a very friendly media, shrinking, gluing itself, etc. I worked a little bit with fiberglass & bondo when restoring a Chevy my grandfather gifted me. The car turned out great, just like your mold. Sometimes the best way to learn is just do it. You learn new skills and perfect them with lots of hard work and creativity. I can still recall coming up with an innovative way to get an almost mirror like finish by topping the resin and fiberglass mat with sheet metal while its curing, then pealing off metal when plastic is hard. Congrats again, and as always, thanks for sharing.

I use wax paper works some of the time. But great job congrats . For quick decoy molds I use cement it works for least 2 doz

Mate you made awesome work I don't understand why you not using Instagram platform... Hope see you and spoken with you about your hobby. Cheers with Ukraine ❤️🇺🇦

Hi Can you make airscrew with aluminum or brass

yooo you listen to crowder! very good!

It looks like you're missing some grooves in the sandcasting flask. They make it less likely that the sand falls out. Nothing fancy, you can just route a groove somewhere on all sides on the inside, so the sand has something more to grab on to. Doesn't need to be aligned or even straight.

if you need a solid mould for the sand just do a plaster case, you can layer it with something to give it strength if needed but plaster would seem like it would do what you need here, and you can use Vaseline to stop the 2 sides from sticking

have you considered to use wax instead of resin and just going the lost wax route from there? If so, what made you decide against it?

I can't stand polyester resin anymore, but if you're going to work with that regularly, do get yourself a bottle of PVA release film. Makes the task so much easier. Bonus is that it's water soluble and will just wash off with warm water when you're done.

Whatvis your souce for expanding EPS beads. I picked up some heads and body molds. And have no knowledge of resources. Thx in advance.

Don't pour the resin into the mold and let it harden. Just wet the surface with a brush, put a layer of fiberglass fabric on, and wet it through. One or two layers of fabric are enough. The less resin the better as long as the fiberglass is wetted through. The resin is just brittle. The glass is what gives it strength. And do not use a spray type of mold release. You need a hard surface. Use a specific wax for fiberglass molds or beeswax and polish it to a hard shiny surface.

Man, I read the title wrong at first... I'm sorry hahaha 😂
