Hi
Today i bought myself 12-13 sheets of biofoam from sitaram stationeries of various thickness - 3mm-10mm.
Well biofoam/depron is now what actually i wanted to buy, i wanted EPO but it wasn't available sadly 

So, i tried cutting foam first time using a precision knife( bought from rchobbyaddict) , which was ok but bit hard to cut depron.
Using a scale,  but still cutting had many mistakes, like cutting in wrong direction in between,etc.

What are the best tips to start with aeromodelling using biofoam? What instruments are must?
Yes i have watched many videos in youtube, but i will want someone to guide me properly with this.

Thanks
Rahul

you only need xacto type knife which i bought from sitaram stationers and also foam from them.. i have been using the knife for all my builds and really works great...
you should also get cutting mat as it is a good addition to clean cuts..
remember to buy extra blades for knife too...

Thanks!   

Yash can you share the address of the vendor who sells Exacto Foam cutter knife and delivers in India.
If I do a google search, all search entries show US and mentions it will not ship to your country   

Any help will be appreciated.

Regards

@tahmadblr its not exactly xacto orignal but there are hobby knifes available in big art supplier shops like sitaram stationers in delhi its usually used by professional artists and not sold under hobby knife search your local stores and ask them if they have knife with aluminum handle they would understand then

yash yes i bought a knife too which came with 5 blades (extra), but i tried cutting the foam(biofoam) keeping it on a thermocol as a cutting mat, but it didnt cut nicely and properly

Maybe your blade is not sharp enough,i use the normal hobby knife i got from them and it cuts precisely on the the biofoam.

rahul its not about blade or foam its about surface while piercing through biofoam it could easily get stuck between thermocole granules so use cutting mat its the only reason
all the best

alright what is the cheapest cutting mat i can buy in india and from where?

can this biofoam be cut using hot wire cutter?

thanks everyone

i think cutting mat is available at sitaram stationers and i bought for myself from hk so it cheap but has weight i bought it when i placed an order of 3kg... it will be between 500-750rs

@Rahul check out my thread i have posted some depron cutting tools. http://www.rcindia.org/electric-planes/'airavata'-scratch-built-t-tail-plane-with-parachute-dropping-for-sweepstakes-14/

Great @nithinraj, very helpful, will go through it once again, after i decide what to make, shall I go with a flying wing ( synapse ) or nutball??
Is my 10mm and 5mm foam good for this purpose?

Go for nutball and use 6mm and 3mm depron.

Rahul,cutting mat is available with sitaram stationers for Rs 400 for an A3 size sheet which i bought a few days back,works like a charm.

alright, will get it ASAP. other than that what glue you using?

I was frankly surprised when I saw the title of this thread. What's the big deal in cutting Depron? I've made 5 models in this material, and never noticed anything about the cutting. Use a normal box-cutter or any hobby knife, just make sure it's sharp.

If you want the ultimate, buy a surgical scalpel with disposable blades.

I use a 20W hotglue gun which works wonders on biofoam,no melting,just pure strong joints.

Okay great, Thanks priyum and sanjay sir
will give surgical scalpel a try..
