Best way to cut plans from foam?

I am going to be taking a shot at my first scratch build tonight and was wondering the best way to cut the plans from foam? After taping the plans together should I trim close to the plane outline, lay it on the foam and then cut along the lines(cutting thru foam and paper) to cut out my model? Or should I cut the plans on the exact plane outline, lay on top of my foam, and then just trim around my paper template(only having to cut around the outside of the plan)? Hope this makes sense the way I wrote it

Thanks,
Jared

I use sewing pins to fix each part (from paper plan) on the foam, and then use craft knife to trace around the edge.

Good luck on the build! There will probably be a bunch of different ways of doing it and you have to try a few to find the one that works for you. The way I do it is to cut out the plan along the lines. After that I lay the plan on the foam and trace around the plan with a ball point pen. Then use a scalpel to cut out the plane. I like scapels with a #11 blade, they are real sharp, cheap and I just replace the blade after it gets dull. I got the box I use off Ebay and it came with a free handle. Whatever method you use just make sure you have a sharp blade and go slow, you don't have to cut all the way through on the first pass.

Hope this helps

I glue the plans on posterbord, then cut out templates from it. The templates can them be traced out on the foam, and they are reusable for later build/repairs.

sticking plans to foam

I have been using a Scotch Restickable Glue Stick (catalog # 6314) to temporally attach plans to fff, epp, metal and balsa. The plans don't move around and it comes off cleanly. You can also leave it on for a couple of days as well. Just rub the stick directly on the back of your plans in spots, lay it on your material and rub it down. It is like the glue on Post-It-Notes.

ForceFedDSM, if I were you, I would use this. www.phlatboyz.com It's the Phlatprinter. We're probably a little biased though

I can't wait to use mine!

For now I am stuck with printing on paper, taping the freaking pages, cutting out the templates, taping the templates to teh foam, cutting the foam around the templates.....and finally actually building the plane......

Like I said....I can't wait to actually use my PhlatPrinter......

I saw that, but since this is my first model, I figured it would be a little overkill for now BTW great work!

I cut out patterns and then apply glue stick to back around the perimeter(heavy).
Then I use a jumbo magic marker and put tip half on paper edge and other half on foam and trace it out. After you peel pattern off you can cut the patterns out with a rotary razor cutter(use large and small) and then use x-acto for sharp corners.

Then take patterns and stick on posterboard to save for next plane.

BB52, could you describe this cutter and how it works? how is it better than a knife? Is it like a Dremel or what?

It is basically a razor blade that is disc shaped mounted in a handle.
I use the larger one on long strait cuts and smaller one on more curved cuts. Be very, very careful with this cutter as it will cut you bad if you slip. Stay's sharper longer than regular razor blades and would not trade them for nothing. Needs to be used with a cutting pad or similar surface to keep it from being dulled. Buy mine at a dollar store 3 in a pack for kitchen chopping veggies(cutting pads).

I have a Fiskars rotary cutter that I use. I bought it at Walmart, and it is designed to use either 45mm or 65mm blades in it. It also have a nice full grip on it, a thumb release for retracting the blade, and a full wrap guard over your fingers. What I like about this is that if you put a 65mm blade on it and extend it to the 45mm setting. With this setting, you can easily cut 2 layers of FFF in one pass.
