Someday, when my router is done, I'm going to have to see about carving some foam...

oops, didn't realize how much profanity was on this site so I pulled the url...

Sorry about the post.

Thanks for policing your own post. ;)

This is a greats site and one of the things that I like about it is the fact that there is a higher standard here. -Doug

What type of foam isfoil?
Pink/Blue foam like the Home Depot or HDU's?

Laff Riot,
Spray Foam... at least thats the idea. Someday I hope to carve foam for marine applications. I have some goofy ideas about hydrofoils and have been dreaming about doing something for years. The computer case the guy posted was of hand carved packing foam. I am juiced to carve shapes and foam would be the fastest...

One of my suppliers, Industrial Polymers has some stuff you need to look at. I highly recommend this company.

Check out thier expanding hydrospan.

" When parts cast from HydroSpan™ are soaked in water they accurately increase in size 60%. By making larger silicone molds from the expanded HydroSpan™ , you can produce a series of progressively larger molds. "

For minimum investment you can create small scale master parts - scale them up - then use there spray foam series for the final.

Thanks Laff Riot, I'll check it out. I've never heard of anything like it....

Thanks for posting the site! A new source other than smooth-on, replicast, etc. :banana:
Hopefully they sell small batch sizes in all their products.
Thanks heaps - cheers, Jim

Glad I could help.
Please post any sites you have for other chemical companies.

Never know when goop in a can will spark another line of thought..
