Seat Diaghragms

Post by scimjim » Thu Nov 15, 2018 11:00 pm

Bought mine some time in 2016 but I can’t find the receipt to show where I got them from :oops:

Anyway, they appear to be in perfect condition - and they’ve had some use too.

Of course the SE6A used the Nylon Net and bonded rubber side strips that seem to have lasted better than the 100% moulded rubber diaphragms.

But even these do split and break.

A bullet proof repair seems to be the Old School type of webbing if fitted correctly, and the right type fitted.

SE4c rebuilding. SE5a similar it seems!

Speaking of seats, I have a few Black plus Tan Vinyl Original seat covers.

Bases and backs still in plastic.

No one seems to list them so I suppose I should get them out and offer them on scimweb.

I also have a few SE6 interior parts such as Sun Visor panels, rear seat backs, some with hinges, Rear boot area transom panels, in OE and Fibreglass.

I can see a sale coming on for Chrimbo LOL.

I honestly can`t remember what I have Phil

This was compounded when I was given 12 weeks to vacate my premises after 15 years, so most of it was just boxed or bagged and thrown into my mates workshop.

Got lots of Fibreglass repair panels etc, including a New bare SS1 door and inner wing ( I think).

I found an MGB diaphragm which fitted the frame of my SE6a quite well.
Drilling of additional holes in the frame was needed and the clips were replaced. If I remember correctly they came as a kit with the rubber.

Is it possible/worth amending the topic spelling mistake for this thread......Diaphragm instead of diaghragm for easier finding on search?

Oh dear I bought and fitted these rubber ones from MGBhive in my GTC. After 4,700 miles the drivers one has now torn at 3 hook positions.and the passenger one (much less use) on very quick look while still in car has at least torn on the nearside rear diagonal corner. I am only 13 stone and can honestly say car has not been use in trials where "bouncing in seats" is required.
The first one I received had already got one metal bar pulled and was immediately replaced.
I would therefore recommend NOT using this type (it should be noted that several retailers sell the rubbers but I believe they are all from the same source.

As a (temporary) remedial measure I have fitted 2 plywood sections that sit on the metal angle that the seat cover clips onto (thanks for the idea frog giddo). BUT on first trying it out I was found to be sitting noticeably higher and had to further recline the seat back to achieve a good sighting forward position (I am 5 foot 11 inches). Also after one 35 mile journey I feel that the seat is now obviously harder and not as comfortable as previously. I shall wait and see how it feels after further use. So I would definitely say use the good quality rubber/fabric strips as per AJL repair. Has anyone used the fabric strips also done by MGBhive??

That is why I convert seats to Pirelli Webbing when they come in for restoration. Never yet had one fail. Work out to about the same price too. Four extra holes to drill and a couple of extra hooks to fabricate to fit them.
This is one in progress, the four here are supplemented with two diagonals...

1. How are those metal parts fixed to the webbing?

2 .I have (used) the 2 sizes of hooks when fitting the rotten rubber diaphragm. 1 3/8 inch for the 8 parallel to frame hooks....2 front, 2 rear and 4 at sides; and 1 5/8 inch for the two front corner diagonal-to-frame ones. (as per the photo of the green one back in this thread)

3. Extra holes already had to be drilled. I am trying to get away with least amount of work/cost so thinking of just removal of rear of the 2 ply bases to fit 2 cross webbings so perhaps only having to disturb only one corner of the upholstery and its clips along the rear and 2/3 on side in front of corners.
Perhaps wishful thinking as that would not allow the front to rear support. (would be leaving in torn rubber diaphragm)

4. How much for you to make the webbing to send to me (per strip)? Looks like maybe have to bite bullet and remove full upholstery and its clips :cry:

Here is my ply base.

Alternative is to strip off seat cover and copy your layout BUT with diagonals being hooked on existing front outer holes.......this would have advantage of moving rearwards the crossover point of the two to nearer where the most body weight is located.
I wonder how much give there is? how far does the strap sink at that area where the max body weight is located??
