Scottie's Tribute A352 build

31 Jul 2014, 3:24pm
I had thought of that WCA, but discarded it as too much work, but may give it more thought.

You are right, in that it needs to push the door outwards like a cupboard door does.

Perhaps cupboard door hinges are the answer!

When I mpdified the hinges the first time round, in order to make the door fit at all, I most likely made the problem worse.

The angles can get very complex and difficult to work around, which is why I shied away from it in the first place!

I have to do SOMETHING though.

Here you go, the problems i had with door hinges.

Metal plate to hold hinge cut to fit in the body


Scimitar door hinge fitted in plate


Plate and hinge fitted in car


First doubts creep in


Quick look inside and it looks okay


No, that hinge lloks to be at the wrong angle to mount the door


Arrows and MS Paint shows thAT IT WILL NEVER WORK



I really wish you better luck

What were you building there?
It looks a very similar shape to my shell at the sides?

Not sure if your pics will help me, but I understand where you are coming from!

It was a G46 from Gary Kanes who started the Sammio stuff. Crap quality body compared to the stuff Chris kicks out but sat on top of a Scimitar

Look at the Swan neck bit of the hinge to see how they can push out as well as open the door.

I made a couple of versions using card and drawing pins for pivots in an attempt to get the angles right

Scottie - Sorry to hear you are having a bit of a bad run at the moment. :icon_sad:

I dug out this old photo I took of the A352 demonstrator...



It would seem that the side screen had to be cut at an angle to avoid the main wind screen/deflector when the doors opened.

Although I know that is not much help with your problem. :rolleyes:

Good luck, Paul. :)

Thanks for the input Paul, yes you are right, the slightest angle of change, seems to make a HUGE difference as to how the door performs when it opens.

I think before I do any huge amount of work (possibly in the wrong direction) I need to play with it a lot to see all the possibilties, and to figure out what the correct thing to do is!!

Quarter Lights

Scottie

Could you not have perspex quarter lights fixed with a bottom swivel to the door perspex so that they only needed to be folded backwards and downwards flush with the door top to open the door? Some sort of inconspicuous catch would be needed at the top join but it wouldn't (IMHO!) look as out of place as fixed quarter lights.

Whatever, I do Mick, if its in the area of quarter lights, the door must be able to open without doing anything else first.

Otherewise passengers would always need to be briefed, or something would be broken if they opened the door normally.

I really did think of a similar thing, and discarded it for that very reason. Just think how irritating it would be to have to remember to do something else every time the door needed to be open?

Looking at the picture of the demonstrator and then your car shows the problem. The door pivots around its front edge which on the demonstrator is aligned with the back edge of the windscreen. Because the pivot point is aligned with the front of the door and the back of the screen the two stay aligned when the door opens so nothing touches.

On yours, the windscreen stops a couple of inches in front of the door edge. This means if you extend the side window to meet the screen it will be in front of the pivot point and so clash when the door is opened.

The choices are to move the windscreen back (or fit a quarter light) or move the pivot point forward. To moved the pivot point forward you would need some long and strange shaped hinges. I am guessing a quarter light may be your better option if you plan on keeping that windscreen.

Thinking a bit more, could you get away with just widening the screen at the base?

You would need to mock it up with cardboard or something to check, also might look worse

Just like in my Dutton Phaetons and Westfield Seven - "Don't hold onto the windscreen frame to get in or out!"

In the above picture, when the door starts to open, the front edge of that ally, which would be the window, moves at a 45 degree angle outwards, but also forwards, so putting a bit at the bottom would actually make it worse WCA

My thought was the side window would move into the car like on the door below. Looking now I guess that would cause sealing issues though.

Closed


Open

Mmmmmmmmm.

It is a bit of a bummer. However, it is an engineering problem and can be solved, I just have to work out how I am going to do it.
I still lean towards a quarter light though.....

Thanks for all the input fellahs,

Watch this space..........

Can't you put the hinges in the back so they open like "suicide doors"?
1 Aug 2014, 3:05pm
Well, I have given this some thought and a cunning plan is forming....

No.

Later on Friday

I thank you all for your input, and I do consider all your options.

Putting the hinges on the rear and making the doors into suicide doors, is a good idea, but like they say on "Catchphrase" sorry, its the wrong one!

Re-doing the door hinges WCA, is so "last week"

So, on with the cunning plan..........

I will go ahead with what was my first gut feeling when I realised with horror that I had screwed up badly, which is ------quarter lights.

Quarter lights seem to have put some people off a bit, but not me.
I see them as my salvation, and my reasonably easy way out of this mess I'm in.

I will make them in stainless steel, so they look like chrome, they will match the rest of the exterior trim, and be elegant and hopefully look the part and look as though they should be there.

I have made a mock up to give myself an idea of what to aim for, and here it is:


Watcha think? Look okay?

Lower the car even more, fix the doors and just step over them to get in?

The hassle I had with the doors on my G46 build was what inpired me to keep the BMW doors on the Z300s
1 Aug 2014, 6:39pm
If it was just the doors WCA I would, but stepping over the side windows as well, I'd need to be 8 feet tall, then I'd not fit in the car anyway!
1 Aug 2014, 6:41pm
Do you have any pics of your G46 completed?

Would be nice to see if you have. I'm sure they would be popular with all on the forum.
