Lost Foam Casting CrankShaft Truing Stand

In this video, we lost the foam cast of the base for our crankshaft truing stand. We start with machining the parts out of high-density foam and then cover them in drywall slurry to improve the surface finish. Then we bury it in sand and cast it with aluminum scrap metal.

Technically what you have is a furnace and not a foundry. The problem is some newbies did early videos years ago and misused the term and not it is quite often used. A foundry is a place where metal casting is done.
As far as the heavy weight of your loaded box. Why not two boxes? Less awkward and less weight. Reserve the big box for the jobs that need it.
I found your channel yesterday. Its nice to see useful stuff being cast along with decorative items.

Yes perhaps i used Foundry out of context .lol . Yes smaller boxes are a good idea . I built the box quick and dirty with minimal supplies on hand and am suffering for it now.
Glad to have you added to the chanel . Keep in mind im always open for constructive critisism and help if you want to.
Thank you rudycandu

This came up in my feed today. Very interesting. It's been some time since I tried my hand at some lost wax casting. I can see the advantages of being able to easily shape the foam - and that it is readily available - compared to the wax. I'll have to check out your other videos on the subject.

Awsome . Let me know if you have amy queations . :)

I really like the simplicity of your methods

[@Wrighmachining]

Thanks tkelker ! !

Could you build your box without a bottom, stick it in your job box, fill it with sand, then do your pour directly into your job box? That way you can just lift the box off when you are done. Any overflow would be into the sand in the job box. It means lifting the molten metal higher so that might be a problem.

[@Wrighmachining]

That is an awsome idea i like the direction of thought on that. The only draw back is that i would be running very high for pouring . I will think more on that idea and see if i can incorperate it into the set up .
Thank you mark !

@@Wrighmachining Maybe use a rope and pully attached to the garage?

[@joell439]

Or dig a big hole to bury the job box 😉

Instead of the tap magic, try some denatured alcohol or turpentine. Lots cheaper and smells better. The DNA evaporates off and dont make a mess at all and prevents chip weld.

[@Wrighmachining]

Thank you . I will try that

[@qianjinTV]

Friend, I think your work is great. If you buy a sandblasting machine. Your work will be more perfect.

[@Wrighmachining]

Thank you for your sugestion and kind words

[@MarkATrombley]

Just noticed there is a typo in the title - loat instead of lost.

[@Wrighmachining]

Fixed !! Thank you

What you spray on foam before cnc foam

[@Wrighmachining]

Good question , its 3m adhisive spray . I only spray on side and stick it down . Some times i even lift it once to reduce how sticky it is .
