Would this work?

Same vacuume setup
lay the cold zepron over the model and pinned down.
Then use a heat gun.

I dont think so.....There is no Vacume......The vacum sucks the hot foam...down....you can even get detail..

Now, This is getting interesting.

Hey,

Let's work together. I'm really interested in what you've been accomplishing. I've been experimenting with the BlueCor, but because of its thickness (I think) it needs to be heated evenly before it can be formed.

This stuff cools too quickly to make it from the oven to the mold. That's why until now, I've been doing the entire process inside the oven. That's a bit of a problem, since I need parts that are larger than the oven is. The other problem is the mold material. I've been trying wood as a mold, but it doesn't hold up to the heat very well. The Frisbee mold is starting to warp from the repeated heating and cooling. I'm working on it though.

I'll keep you all posted. Thanks for getting me moving again. Let's get this to work.

-Dan

Convergence

What I am particularly jazzed about is the convergence of my experiments in slicing F3 and this very simple and inexpensive vacuum forming apparatus. I always thought of this process as requiring much more sophisticated equipment and as being more limited in the materials which could be formed.

Beyond using existing models, this could allow for building quick airframes with small variations.

Great stuff. Looks the home center gets a visit tomorrow.

I have Several box's made......12by12 12by24....The Sheet's I get
only come in 12by24 Plus most oven's are not over 24 inches


For you guys that do not have the cash to build the rig....
all most ever on has a home vacume cleaner
Use one of your mom's/wife's....3 inch deep Cooking pan's
cut a hole in it.....For the vacume hose......Get some plywood That will cover the pan drill hole's every 1/2inch.....and all you will need to buy is the angle Aluminum and weather stiping.....and Clips and your set.....

Guys, you might want to try polyurethane foam for your molds. This is commonly known as sign foam. It comes from 1/2in to 12in by 48''X96'' sheet, that I have used. You can coat this foam with just about anything,primers of all sort polyester resin, etc., m.e.k. doesn't even bother it! This foam sands like basswood without the grain.
I work in a plastics jobshop and we make all of our patterns and plugs out of this foam. If you want to see some photos of this go to my web site.
Thanks,

me too, I'm sure they wait for us to go to bed before they post the best stuff

It looks great, might have to try it myself with Depron. Matt Keennon has done it with the really thin 1mm depron but in that case you need a really good oven as 1mm depron is stange stuff. His oven is industrial I think and has indirect heating and high velocity airflow around it to give even heating. It looks like this Zepron and probably 3mm/2mm Depron as well are more tolerant.

HEHE...I was in bed too

My school has 2 vacuum formers, so I guess I could try using the real thing

They have heaters that you pull over the plastic/foam, and then remove when forming

I have used them for plastic forming, but i dont see why it would not work with 2/3mm depron

Kirby Well You allways could ......Buy A used oven for cheap
or Build you a Vacumfrom Oven.....Its really not that hard....
I havent had time to build mine.....but I have a the parts to do it

As for Order's.....Of what?....
All kits are Copy Righted So I dont Its a good idea to Sell Copys
of foam model kit's I dunno...

But for Sure a Bardering system would work
back In the day I did this all the time with model's kit's
I think the Tradeing should be Free....or just the cost of the Foam
and shiping......When you get 100 or so guys....Maken Kits you wont have to buy so many model's

Well That just my 2 Cents on that subject...
