I believe no, those are 'bumpers' or 'stops' that keep the door from opening too far and damaging the leading edge.

I don't mean to answer for Hachille, but that's my English translation of what I've read so far.

The doors don’t have a well defined opening stop. Hachille added these to give the door some way of stopping in the open position. Otherwise the door might bang into the body and chip paint.

What stops them with the original setup?

Before I took mine apart, an edge of the door kind of jammed into the weatherstrip around the door opening. Pretty vague stop, really. I could imagine a differently adjusted door getting paint on paint contact, which would eventually chip.

I really like the big idea here. I have a new body with doors etc arriving soon.
Initial questions - are there any other drawings photos sketches etc of the installation?
And in detail - how are the plastic ball housings retained in the door? -  adhesive or mechanical  ie small screws.
Or have I missed something
Which is entirely possible.

Thanks
Grant

If I am not mistaken they are a press fit in the door bobbin after you drill them out with a 26mm drill bit?
Is that correct Hachille?

yes that's correct. It could also be glued or screwed in if needed. But I've never needed it.

Thanks for the quick response.
As far as I know, the new doors do not have the metal bobbins moulded in.
The body is from Banks/Lotus Supplies and I guess they expect that you will use their door hinge system.
Guess I'll have to do some re engineering!
To be expected on Lotus projects.

There is a vertical thick foam strip at the front inside corner of  the body where you can imagine that the leading edge of the door would strike the opening.  If you look from the outside as you CAREFULLY open the door, look where the leading edge of the door moves in relation to the body, and that will inform where to put the replacement.  I just used foam weatherstripping with a spit coat of adhesive on both the body and the foam (so as to not ruin the freshly painted body) to 'improve' the bond (yeah that is my story I'm sticking to...) where the Hethel gnomes originally placed it.

YMMV.  It held up for the 12 years subsequent to the refinishing, so I guess it was a good idea and never chipped the leading edge of the door.  Was it right?  It worked.  That's what counts.  Can you overthink it?  Yeah, but pretty sure they didn't back in the day.

Hachille does the door rest on the nylon piece you machined to set the height and rotate on it too?

It is the ball joint that presses on the part that must be manufactured for the height. But since the outer ring of the ball joint is fixed on the door, I can say yes.

'Web lied to me!
I was going to buy these today, but there is NO McMaster Carr in Reno.
So I will order a set in the morning to get this sorted out.

McMaster-Carr  1071K25 four pieces ordered.
So now I will have parts to work with.
Once they are in hand this should not be too hard to sort out.
