hey guys

i build my first (scale) flip flop hinge yesterday and i thought i would share how i did it
first off, the tools needed



we have
gleu
super gleu
metal rod
styrene tube
a knife
sidecutters

we start of by putting a little angle on the rod (i used metal but you can use whatever you like)
this little angle will end up being the hinge point on the hood (or trunk if thats what you are building)



once we have the first angle in there it is time to consider how long the first part of the hinge needs to be
it should reach from where ever you put the hinge on the frame to a point past the front bumper BUT it should NOT be longer then the space between the hood and the top of the frame or the hood wont close



once we have decided on the right length we can make another 90 degree angle in the rod, this one facing away from the first angle by 90 degrees (hard to explain so here is the picture)

now it is time to put the third angle in the rod
(once this angle is in the little hinge point on the very top and the long end of the rod should be pointing the same way)
the one thing to consider when making this angle is that in order to lift the hood over the front end of the car this section needs to be AT LEAST as long as the distance from the top of the frame (if thats where we mount it) to the top of the front end



congratulations, we have now made one side of the hinge
this is the time to cut down the styrene tube and slide it on the rod
make sure it is long enough so that the hinges will clear then engine but narrow enough to fit in the engine bay

the car i used to do this on was perfect for this since it doesnt have inner fenders
if your car does have those you might want to consider cutting a groove in them for the hinges to travel in

with the styrene tube in place it is time to repeat the first steps and replicate the hinge on the other side of the rod

once that is done it should look something like this



and with the "hood" open



as you can tell i have allready gleud my hinge in place

now is also the time to build the hinge points for the hood
for this we will cut two little pieces of styrene tube and put them on the very ends of the hinges



now it gets tricky
we have to figure out a way to mount the little styrene hinge points to the hood

i did the following...i mocked up the body and the frame and then put a tiny drop of superglue on each one of the styrene hinge points
then i put the hood in place and while holding it with my hand i turned the model upside down
with the remainder of the styrene tube i reached through the bottom of the frame and pressed each point down for about 10 seconds for the superglue to settle

this is what it looks like closed



on its way open



and open all the way




well, there you have it
this is the way i do it let me know what you think

that is pretty cool and I like what you did to the hood. Thought about puttin Pink Lady on my next build but goota get done with Jimmie first. I sprayed gloss enamel clear coat today and it seems pithy lookin...not smoooth. And thru the advise from the hobby shop..I sprayed with the windows in. Might have been too cool. Can I lightly buff the body and respray.Without messin up the decals ? Should have sent you a picture but still workin on that. Maybe later. thanks

as you can tell, the body on mine isnt done yet either, i just sprayed on two quick coats of clear to keep from rubbing the paint while handling it
thanks for the compliments

what do you mean with the windows in?
you mean you glued the glass in place and then clear coated it ?

thats new to me
anyway, yes, you can buff the paint but what i usually do is wetsand it first
go on ebay and look for a "polishing kit"
it should run you less then 20 dollars shipped and include several cloths ranging from 4000 to 12000 grit

that should smooth your paint right out

HOWEVER keep in mind that when you polish the high spots get more of a treatment then the low spots so be very careful around edges
i always put 2-3 coats of base down and 3 coats of clear and it is not uncommon for me to polish down to the primer

If I had seen this a month ago I would have done this a little differently.



Im gonna keep this in mind for a future project though, great tip! Will it work the same for trunk too?

that came out pretty nice

i see you figured the picture posting down aswell, good

if you ONLY buff it with some compound then you should be ok
BUT i always apply at least 3 coats of clear

then again, i do wetsand my paintjobs

love the paint sceme on that one

it might not be to hard to redo the hood
but then again, if you are pleased with it you can always save this for a future build as you said

it should work the same way for a trunk
might even be easyer because there is more room in the trunk for the hinges

plus, you can go with the "standard" way of flipflopping a trunk
(like such)



or you could go with a radical but completly useless flip flop and put the hinge in the same way as the front is done and have the trunklid sit in the back of the car



what would be really spiffy is if you were to build a james bondish pickup truck with this hinge under the bed so that the bed could hinge up to display the missle launcher

[vaughn]

On the posting thing...kinda. I go around the world to get across the street, if you know what I mean. I could probaly cut out about half of the steps I go thru. will get better.
