please elaborate as bonnet and hoods are the same things!
are you talking about the toms air scoops or are you talking about the front hood with the drop down centre?

[airforceone]

Bonnet=Hood
Boot=Trunk

Chris is on the right track, what exactly are you trying to do? Remember that things are a bit different in Yurp

Lorry=truck
water closet=bathroom
etc....

I hope u dont mind me using ur picture Chris, this is what he is talking about. He wants to know how to make the part that angels up, he already knows how to make the air hole, but just needs to know how the scoop curves up.

It's an amaxing technique really.
You use sheet styrene as a frame and putty to create the curved sections.
You then use sandpaper to smooth the surface and create the final form.

If I remember correctly, appleseed created a little "how-to" in his FTO thread. Maybe a quick search can help you.

^^ just what i was gonna say

try using cotton thread to cut the holes though, thats what i did for the slot for the velocity stack on my superbee, drill a whole in the center of the areas you are gonna cut, run a piece of cotton sewing thread through and go back and forth cutting it out all nice like

Using thread would be alottt.... harder than just using a detal scribe & xacto, cuz if u use thread its alot harder to menuver than a xacto can do, it would also save the trouble, thread is alot faster but not as accurate and as easy.

Actually, I would think it would be just the opposite? Cutting curves with an exacto is difficult, but with the slow sawing action that can be acheived with thread, you can easily change direction, follow complex curves, and do fine cutting. Like a jig saw as opposed to a circular saw.

i agree completely, plus an exacto can slip up and slide all the way across styrene then you hafta fill and fix yadda yadda, thread is much more controlled and easier to handle around corners with even better speed!

IMO i think a xacto would be easier to handle, but a thread would be easier to menuever, thats whut u was trying to say. But IMO i like using a xacto.

Whenever I've tried to cut with a thread it always ends up snapping after cutting a few mm. So I revert back to a #11 blade and etched saws. Don't know what I'm doing wrong, what type of thread do you guys who have been sucessful use?

[jgmodelcars]

well its just personal preference, i like each for different reasons

i just raid my moms sewing basket for thread, you have to draw it back and forth a few times to heat up you can't just start into it, it snaps sometimes but just cut a long piece

hope this helps!

Perhaps that is it. Maybe I'm using too short a length, localising the heat and causing it to snap. I'll try a longer piece next time. Thanks!
