MG MG Y Type - Sun Roof Trim.

G'Day,
I'm in the process of trimming the sunroof, at the rear on each side are 2 metal tabs with 2 holes in each tab. These must take felt, (or something similar) to guide the rear of the roof as it slides. Could anyone let me what it is, & how it is fixed to the tabs please? A photo would be even better!!!
Cheers,
Mike.

Do you mean these? - see picture.

Yes they are the guides and it was just a strip of felt I believe. As to how it is fixed, if you confirm that we are looking at the same thing I will check further for you.

Hi Paul,
No, those ones you show are at the front of the sunroof,(I have those), the ones I'm not sure about are at the rear. I can't find referance to them in LTBY's or any photo's anywhere. My car came in boxes already stripped! Thanks, Mike.

G'day from up above Mike.

I found a photo of an old sunroof - are these they of which you ask?

Unfortunately it was a long time ago since I pulled the sunroof out so I cannot tell you how the felt pieces attached or how big they were but hopefully if this is the right part of the roof, then someone else may know the answer.

Hi Mike,
Since reading your post, I have been racking my brains to remember if I had an old sunroof somewhere. Woke up early this morning with the answer. Been out to my shed this sunny morning and found it.
The two metal tabs are offset and support the roof on the frame that it slides on. They are felt covered and you will see from the attached photos that the felts are folded differently and are fixed with small bi-furcated rivets with the heads on opposite sides. This is so the legs of the rivets don't catch on the slide.
Let me know if you need any more photos. Good luck.

Tried to upload 3 photos?
Try again with one!.

Thanks Corry and Keith for helping out with additional photos.

Normally if you have problems uploading a photo to the Bulletin Board they are too large so a quick resizing will be required. I normally use 3.5 inches on the longest side and about 150 pixels per inch for photos on the website which gives a good compromise between definition of the picture and transmission and I think Mike Plumstead has a similar size limit on photos here too.

You can also use thin leather for these - well greased - a little more durable than felt.

The hard part is finding a hardware that still has or knows what a bifrocated rivet is ?.

Hi Mike and Tony,
Yes, leather can be used but make sure the heads of the bi-furcated rivets sink below the surface of the leather so they don't grind on the channel. With 1/8 inch thick felt, the heads sink in quite easily, that's probably why they used it in the factory. The bifurcated rivets are approx 1/2 inch x 1/8 inch. They are also used to secure the 1/4 inch thick strip of plywood that runs along the back edge of the sun roof to which the headlining is tacked.
Plenty of bifurcated rivets on Ebay if difficult to source locally.

Hi everyone, Thanks for your help, sorry to have disturbed your sleep Keith! A photo is worth a thousands words as they say. I have some felt which I will use. I also have some bifurcated rivets that I bought at a large hardware store (Bunnings) here in Canberra. Any up your way Tony? Thanks again everyone.
Cheers,
Mike.

Hi
coming slowly to an end of my restoring
last big step is the sunroof,
made a lot of pictures, about 1200 or more
but always the same
one picture is missing


i need a picture from the back to see how the cloth is fixed there


in the front i have a lot of pictures

my english is better than 2 years ago, but still a picture says more than 1000 words

I have installed the sunroof today and it works as it should, that's the best thing
now I have to put the cloth on

so if anyone needs information in the future
here is a lot of it

https://www.mgexp.com/forum/t-series-and-prewar-forum.46/mg-ya-no-1675-from-1948.4022768.4367557/page-58#msg-4367557

have some little problems on the roof, have to cut away some rusty parts, but no problem i hope

i can close it
i can open it
some work and it is ready M ;-)





FT Franz

now i have understood it,
in the back there should be a wood part to fix the cloth
i haven t seen the holes for the screws there
all black ;-)
so i have to cut a parkt fix it with some screws and i can fix the cloth tehre

i have seen and understand it when i have put the sunroof in the car and closed it

soem more pictures in my blog

Mike,

I fabricated the guides from a solid block of PTFE. I suspect nylon would work as well. These materials have several benefits over felt and leather: they are impervious to water; proide a much more precise fit on the roof rails; and are self lubricating - no wax or lubricant required which could soil the cloth headliner. I attached them using split rivets as original.

I sent Paul Barrow a set of engineering drawings of both the front and rear guides several years ago. I do not know if he posted them on the site. (sorry I do not have a digital version).
Rodney C "Rocky" von Dullen

good idea

you made the hole part or only the part which is normaly felt?

nylon printing in 3d is a little bit difficult, my printer can only print 250 degrees

but i could cut the front part in one part, the hole part, metal and felt, with my mill

could make a new 3d drawing, for printing too with freecad, easy part

you have done it ?


found ptfe in the bay for some euros ;-)


the only question ist
what is with rattel?
felt would stop it
FT Franz

Herr Franz,

I fabricated the felt guides from PTFE. The rear metal tabs were in fine condition - no rust. Same for the adjustable front guide holders.

I found a copy of the drawing I sent to Paul back when but it is too large to load as an image attached to this message,.

A solid PTFE bar stock 3/8" X 1" X 7" will make two front guides and four rear guides. I used only a router w/ 1/8" straight bit, a drill press w/ 1/8" and 60 deg countersink bits and a sharp knife. No 3D printers required!

PTFE bar stock is readily available on the internet.
