how to transfer paper plan on foam


I know this is a stupid question but I'm just looking for an idea to transfer from ink jet paper plan to a foam. Since I'll be using a cutting hot blade to cut the foam I can't just glue the paper on the foam because I won't be able to cut it. What's the easiest way to transfer paper plan to a foam without drawing the plan on the foam?

Al, no question is ever stupid. Its still got to be answered. The Fella's here might have different idea's but I just glue my my plan with a glue stick ( kids use them at school ) onto cardboard templates. Cut out the templetes and either, weight the plan on the foam or stick it on with double sided tape and cut. I've seen some of the fella's make templates from thin ply, circuit board plate etc. Something that doesn't burn easily. Hopefully this might help but one of the fella's hopefully will jump in here with other idea's.

I glue the paper plans onto big sheets of posterbord or other cardstock, and cut out the parts. The templates can then be used to trace onto the foam, and they are reuseable.

What


I'd do is use your iron and try to iron the inkjet printout onto the foam. I would work slowly and try to wet the paper after it's been laid down onto the foam. I've never tried this, so write back if it works.

I believe it works only with laser prints because I've done PCB's before that way.

Another technique. Scribble on the back of the plans with the darkest pencil you have. Doesn't have to be precise as long as you darken about where the lines are on the opposite side of the print. It helps to use light paper so you can see the lines on the reverse side. Once you've scribbled the outline, lay down on your foam and trace the plan from the printed side. It essentially becomes carbon paper and leaves a light imprint of the plans to be cut.

I have tried using sharpie and it doesn't work extremely well: tape the plan on your foam, and then write on the corners until it bleeds through. Then use a ruler to connect the dots .

I cut out the paper templates, set on top the foam sheets, outline with pen, and cut out. I'll have to give the card stock idea a go, would make for durable templates.

Acetone on posterboard


Transferring the plans to posterboard.

Posterboard makes an excellent template for foamies. The full size plans will fit on a typical 22" x 28" piece of posterboard. I get my posterboard from my local Staples office supply store. The stuff I get is the consistency of a poker card and is insanely cheap at about $2.50 for five sheets. To render your plans on the posterboard, simply lay the plans face-down on the posterboard and weigh it down with shot bags or pins.

Put plans face down over posterboard.

The next step is to use white towel (an old athletic sock works fine) to wipe on some Acetone. Make sure that you have adequate ventilation because the Acetone is smelly. You just want enough wiped on to render the plans "clear" from behind. Wipe down all areas where there is drawing data to be transferred to the posterboard. When complete and dry, slowly peel off the drawing and you have a set of plans on posterboard.

Is a "cutting hot blade" the same thing as a hot wire cutter?

Never tried it before but I'll be using a cheap method and it should work pretty decent. I'll be using my Soldering iron with attached hobby knife blade. It should probably cut the foam like water.

I just print out the plans, cut out the paper templates and then use a very light spray of 3M77 on the pack of the templates and put the templates on the foam sheet or blocks.
When finished, the templates just peel off. I have re-used them a couple of times. The 3M seems to stay tacky for long while.

After printing, cut out your paper parts and use double sided tape or glue stick to attach plans to foam.

Take foam safe spray paint and spray around the edges of each of your parts, let paint dry and remove your paper plans and you have a perfect outline of your parts. Just cut inside the spray paint line and you got it.

It's a lot easier and faster than tracing each part individually.

Unless you are trying to make multple copies o the same part, template is not needed.

A hot-knife may be good on a straight edge but it does not cut curve well. Might as well use hot-wire. That's what most foam cutting dude use.

For me, making a one-off foam parts is simple. Spray 3m77 or Elmar's spray can on the paper plan (I use letter size), somthime I rough-cut the parts first but most of time I just spay the wholesheet. Wait a few miniutes and stuck it on the foam. Now use a sharp knife, I use disposible single-edge razor blade from HomeDepot (100 for $8). Cut thru the paper onto the foam. That's it.

Remeber, change your blade often.

Enjoy!
