MG TD TF 1500 - TF Body ID Plate Install

I figured out the TF body ID plate goes on the underside of the left side of the tool box cover, but how to attach? It had unusual rivets attaching it when I drilled it off. Would 1/8th pop rivets be inappropriate? Is there anything better?
thanks,
Tyler

Tyler,

Originally the TF Body Plate was attached to the lid of the Tool Box by solid aluminium rivets.The 'tail' of the rivet was peened over on the outside of the lid,not the inside.

If you can recall,I would be interested to know the orientation of your plate before you took it off the lid ie.was the plate able to be read left to right from the front of the car or from the Driver's side?
I have had several TFs with the original rivets intact,however,each car was different in its orientation.

Cheers

Hi Rob
I am in the process of painting my body tub The lid on my tool box and plate is secured with the original aluminiun rivets and when open reads from left to right from the front of the car. Hope this is of some use.

A pic of my untouched plate. Note the black paint under the lid on all cars. Other end of the rivets were peened over as Rob mentioned.

Cheers,
Matthew.


M Magilton

Rob, I have 3 originals packed away, will have a look But Blair is correct on most that I can remember. Matthew shows the same.

Black is correct for underneath as is the space behind the Battery,or battery box.

Blair, I was Tim Gibbes Co Driver in the BDA Escort all those many years ago.

Note on the image the top surface was painted on the ply rear when the body was painted, there by masking off the black underneath. There is traces of the black being painted first then turned over.


Rod Brayshaw

Hi,

Matt.,
Is your plate orientated the same direction as Blair's,ie.read from the front,left to right after the lid is raised?

I have been under the impression that the outside 'tail' of the rivets were left unpainted?

Rod.,
Look forward to confirmation re the orientation of the Body Plates from your stored originals.

Cheers
Rob.Grantham
Rob Grantham

rivets seem to have been left unpainted.

J K Barter

On my TF the body plate is upside down - cannot be read from left to right when opened. I guess they were not paying a lot of attention when they riveted them on.
JB


J K Barter

Same type of rivets used on the TD running board strips but in that case they are counter sunk while these are considered flush rivets.

I got mine from www.rivetsinstock.com

Sorry for the blurry photo.


Chris Couper

Rob

I have only two, the third has been striped for painting but was the same as the two in the image. They are both TF1500.

If the rivets were dabbed with colour like the rivets that assemble the side screen box sections I would expect the alloy rivet would shed any paint as time passed.



Rod Brayshaw

looks like you read them through the windscreen!


Rod Brayshaw

top side


Rod Brayshaw

Mine is orientated the same.
Its not very clear but factory shots like this one of a pre-production car seem to suggest unpainted rivets.
Rob, do you happen to have a chassis number for the lid with the NSW dealers plate?

Matthew.


M Magilton

My Plate is opposite to many of these . It can be read from the engine side

TF
Body NO. 16167

Chassis number TF5663


Max Irvine

Matthew

It is either TF9140 or TF9651 it's a long time ago that we restored those two. TF9140 went to japan and TF9651 went to Guam or Singapore.

The image is TF9140 in Tokyo Japan 1988 at NZ house the trade commissioners property.



Rod Brayshaw

Rod, that picture is so classic!
Frank Cronin

Thank you Rod. It is probably 9651 which was sold new in Sydney and registered in Victoria GJS.200 on 22/8/55, no later info. One well travelled TF.

Matthew.
M Magilton

Rod,
Did you say the back of the battery box was painted black? Was it just the back surface or the whole insides of the battery box?
Thanks,
James
J K Barter

Yes James the entire battery enclosure 4 surfaces see images


Rod Brayshaw

the other angle. Also the base had the black painted thin ply section with two wooden blocks one at each end, secured with bolts.


Rod Brayshaw

Great photos here.

Matt.,the PRE production shot shows the 'erroneous'wire clips(breather pipe hoses
to carby) which were later changed to the Jubilee type clips!

It looks like as suspected the 'tails'of the
rivets affixing the body plate to the lid,were not painted.

I checked an untouched Toolbox Lid/Body Plate today from my garage,and the Body Plate on this TF was read from the engine side!Same as Max Irvines.In this instance,the cars may have varied in the plate orientation.
The underside of the lid had the usual Factory black paint applied.

Agree with Rod that the entire Battery
enclosure was painted black originally.

I noticed from the various photos that the majority of the Body Plates seem to be left unplated? There is no evidence that the plate I checked on today was plated and yet Matt.,your own very original TF1500 has what looks like a nickel plated Body Plate?

Rod,from your experience,were they plated originally or does it vary between TFs?

Cheers

Rob
I must admit I really had not noticed over the years, just got on with the job. Also in the days where we had rolls of film we were frugal on what images to take so lots of items never got recorded.

I am scanning a photo file on a TF we restored for a Sydney owner during 1987 and have some great shots as we dismantled and many of the restoration process we use but the body plate was not a priority to record.

I have 7 plates on hand (some owners request new, so I kept the originals as owners did not want them).

Two TD plates are plated on the back and gone from the front face.

TF there is plating under the rivet head on all that are off the lids.

It looks like a very thin flash could be chrome may be nickel. I wonder if they were silver plated? All the TF plates have traces of plating on the back unlike the TD. Could be a poorer plating type or a reaction to the black paint why there is little left?

I would say yes all were plated TD and TF.
Rod Brayshaw

Hi Rod,

Appreciate your prompt reply and evidence
on the plating query for the TF Body Plate.

I suspect there was similar 'flash' plating only on the small Patent Nos.Plate located under the main car identifying plate located on the lefthand side of the bulkhead.
On most TFs,the black coloured print may survive but the plating is usually pretty much gone on original cars.

Cheers.
TF3719("Aramis"),TF9177("Athos").
Rob Grantham

Tiny bit of plating remains on mine.

Matthew.


M Magilton

Rod,
Thanks, I had not noticed the detail of black paint in the battery box.

J K Barter

Hi Matt.

Thanks Matthew,as I supected the Patent Nos Plate was lightly plated. Appreciate for your spot on photo.

Cheers.
Rob Grantham
Rob Grantham

My patent plate has traces of plating but no evidence that it ever had any black paint.
JB


J K Barter

The untouched body plate on my TF looks similar to the other examples, but it looks more like some kind of lacquer to me than plating.
JB


J K Barter

Attached is a nice survivor example of a TF from the GOF in NY this year.

The patent plate looks to be a nickel plating flash with black paint in the background.




Frank Cronin

Frank,
Thanks for the survivor photo-I guess all of the paint wore off of my patent plate.
JB
J K Barter

Frank, your image shows the aero nut facing upwards holding the bonnet side panel to the firewall bracket.

I have tried to convince others that this was original for years. This TF looks untouched and confirms my findings.
Rod Brayshaw

Rod,
Here is an unrestored car with the same nut on the radiator end of the panel.

J K Barter

Rod B,JB and Matt. M,

I was about to raise the point of the aero nut,(side engine panel to bulkhead) noted being on the top of the bolt connection.

Matt. Magilton showed me a photo of his very original TF1500s side panel being affixed in the same manner.I also seem to remember a few years ago Matt. noticing this set up on another USA original TF.

Although this seems unusual practice,perhaps the bolting up exercise in the Factory may have been done this way for easier fitting.The bolt was a Rubery Owen I suspect,
the same brand as the bolts holding the bonnet top lock part.

I assume the aero nuts were orientated this way for all four(4) bolts? ie.for both the side engine panels?

Cheers

Rob Grantham

Great unrestored car photos there Frank and JB! Keep them coming.

Matthew.
M Magilton

Interesting to see how much packing there is under the forward side panel fixing on the original TF. My car needed at least that much. My radiator has evidence of the attachment brackets being replaced at some time. I did think about taking both side brackets off the radiator and raising them so that I would not need as much packing.
Max Irvine

What I find fascinating these aircraft fasteners is after the side bonnets where bolted up and assembled, they painted the washer and nut body color. Even the tip of the bolt is red body color. As for this anchor nut, there could be several sources. Nyloc - Simmonds Accessories Ltd. Philidas - Whitehouse Industries Ltd.
Oddie - Brown Bros. (Aircraft) Ltd.

The black battery box discussion is interesting. I haven't gotten to that part of the restoration but I was always under the assumption this was painted body color when the tub was painted. Are we saying the only the interior of the battery box is black and the exterior is body color? That will be next on my investigation. I know the thin wood base (probably left over supply of wood skins from aircraft WWII) and the blocks and two bolts were painted black.

Frank
Frank Cronin

All of these firewall plates that are made of brass were originally plated nickel. Note there are two versions of the patent plate (early TD's had a reverse image). Of course the TF car number plate is not brass.

I am still on the hunt for any evidence that the rocker setting plate on the valve cover had been plated nickel. So far no plating has been found.

I will work to get the TF plate added to the etchings page over the next several weeks now that I have some great examples.

Chris Couper

Frank,

The interior of the battery(total enclosure)
was painted black on TFs with the exterior
painted body colour.

With regard to the aero nuts and side engine panels,looks like I will need to change the position of the bolt heads(4) so that the aero nut is on the bottom aspect for the current TF1250.

Cheers
Rob Grantham
Rob Grantham

Hi Tyler,

To answer your original question knock out the central "nail" in you pop rivets, push the aluminium rivet through the plate/tool box flap, start to flatten the reivet with a centre punch(this will open out the body of the rivet) and then finally peen over. If you use pop rivet pliers you will end up with the head of the "nail" in the underside of the lid - very ugly.


Jan T
J Targosz

does anyone have a picture of the plywood battery box floor bolted in place?
J K Barter

This does not show the whole battery tray on a TD but you might get enough of the view.



Chris Couper

JK, here is a good link on TTalk

http://www.ttalk.info/BatteryBoxWood.htm
Frank Cronin

Frank, the red paint you see on the aero nut and bolt is just overspray from a respray. The aero nuts used were "Simmonds speed nuts" according to the Service Parts List.

Cheers,
Matthew.
M Magilton

Thanks Matthew for the proper identification of the anchor nuts used on the TF. The picture of the red TF #891 I posted earlier is an original car with the original factory paint. When you say “re-spray” do you mean re-spray to paint exposed bolts red body color after the car’s body panels construction on the assembly line or a re-spray was done later in the car’s life to care for faded paint? Just trying to understand how the factory assembled these cars. Your input is always appreciated.

On the discussion of the battery box interior color which peaked my interest. I found a picture of my battery box when doing disassembly. It clearly shows the interior of the TF battery box was black. I will inspect it closer in person but it looks glossy – similar to the same paint used under the tool box lid.

Since this thread discussed the inside of the tool box was painted black and the “ghost mark” painted edged outline of this tool box color on the ply rear, do you suppose think the interior of the battery box and the wood was painted black the same time the tool box lid was painted on the assembly line?

JK, not much to look at but you can see the remnants of the surviving wood used as the base, the wood side rails, and the two bolts.

Great discussion guys.

Frank



Frank Cronin

Here's the battery box area from a 53 TD. You can see the bolts that held down the wood. Bud


Bud Krueger

Thanks for the pictures of the battery box wood- mine was in similar condition to Franks picture when i removed it but I am not sure if I still have the remains. I seem to remember the wood looked like mahogany.
JB
J K Barter

Matthew Magilton,

On your original TF1500,could you check and see if the 'aero nuts'on all four(4) affixing points re the side engine panel,are in the 'top' position on your car?

Thanks and cheers.

Rob Grantham
TF3719("Aramis"),TF9177("Athos").
Rob Grantham

Rob, the rear two Simmonds nuts are as pictured, but the front two are gone, probably when the radiator was taken out at some point in the past.

Frank, the red paint on the nut and bracket only shows to the left side of the picture because the side panel was creating a 'shadow' over the right side when the spay gun was applied to the side panel (and probably the bonnet top at the same time) and some paint escaped through the bonnet gap and hit the nut. This could not have been a bodyworks paint error as the car was not assembled when these panels were painted. I surmise this happened either as a factory rectification repair or a later paint job. I cant tell if this involved the whole car or just a patch. Do you happen to have other detail pictures of this car?

My picture shows original finishes except that I have touched-up the black bracket.

Matthew.


M Magilton

Another Simmonds nut on the oil pipe union. I also have these on the horn mounts.

Matthew.


M Magilton

Hi Matt.,

Thankyou as per usual for your prompt reply re the Simmonds Nuts on the engine side panel to bulkhead orientation.

It may be my particular computer screen,but I can see remnants of Grey paint on your TF1500s
Simmonds Nut you have shown in the photo?
Particularly on the 'flats' of the nut.
Other areas on TFs with the Simmonds Nut type include the Bonnet Top Lock parts bolts(8) and the rear spare wheel carrier(3 in total).

From the evidence on original cars,I am confident that at least two(2) of the Simmonds Nuts-at the rear,were placed on the top of the bolting. We need to confirm whether the front pair were orientated similarly by having reference from another
untouched TF.

Great input on this Thread from many informed, enthusiastic owners and photo gatherers.

Cheers
Rob Grantham
Rob Grantham

Rob
I just did not take enough detail images in past years of details like this, but over the 30 TF's we have restored all that we stripped from original condition had the 2 radiator nuts on top like the rear ones.

You know how difficult it is to fit the nuts underneath at the radiator point, I have assumed the factory took the quickest method and fitted the aero nut on top where a speed brace or other socket driver would be much quicker, the adjustments required to align the panels would be easier to adjust this way also. Imagine winding the aero nut up from underneath with a spanner all the way, very time consuming.

It is against usual practice where the item that is being fixed to a bracket or chassis etc has the bolt through it.

Do we agree that there are 20 1/4 BSF Simmonds/aero nuts on a TF?
Rod Brayshaw

Rob, the grey you are seeing on my nuts (trying to keep a straight face here!) is the remains of cadmium plating.

Matthew.
M Magilton

Hi Matt.,

Oops! Apologies Matt. I should have realised that we TFers usually have shiny nuts !(lol).

Now Rod,thinking of the rebuild I did on the current TF1250 some 10 years ago,I will have to work from memory:

Eight(8)- 1/4" BSF Simmonds nuts on the top bonnet lock pieces.

Four(4)- 1/4" BSF Simmonds nuts on the engine side panel to bulhead bracket

Four(4)-1/4" BSF Simmonds nuts for the Lucas
Horn attachments

One(1)-1/4" BSF Simmonds nut for the oil line bracket

One(1) - 1/4" BSF Simmonds nut for the rear
spare wheel carrier(plus I think two(2) 7/16"
Simmonds nuts)

Two (2)- 1/4" BSF Simmonds nuts for the Exhaust Hanger Brackets.

I'll bet Rod you have an original TD and TF
Factory Manual of fastener numbers so you may be at a distinct advantage here!

Please let me know how I went on the 'scoresheet.

Cheers"

The SPL (May 1954 edition) mentions 33 Simmonds speed nuts for the grill assembly.

Matthew.
M Magilton

Matthew,
Where are the 33 simmonds nuts on the grille assembly? Mine is in pieces at the moment and I can only think of self tappers going in to spring clips to keep all the bars in. Are those clips made by simmonds or am I totally forgetting something. By the way I found replacement clips of the same type are available from Roverco.
Max Irvine

Matt., and Max,

Max I was thinking on the same lines as you re the 33 Simmonds SPEED Nuts for the grille assembly. I suspect these speed clips are different from the 'aero type nut' we have been discussing above?

On rebuilding many TF radiator shells and grilles,I don't recall the aero nuts but there were certainly plenty of the self tapping clip type.

Cheers
Rob Grantham
TF3719("Aramis"),TF9177("Athos").
Rob Grantham

I think Rob is correct. The "aero type nut" or also called "anchor" nut vs. the speed clips are two different things. Since the grill hardware is listed as Simmonds manufacture in the SPL, perhaps they produced this type of hardware as well. Just a typo when they published this in the SPL. We know the factory issued books and some pictures Rob has pointed out before (Jublie worm style hose clamps vs wire on the breather) was not always 100% accurate.

I still have my old hardware when I sent my grill for chrome plating.

In the bottom part of this photo are the old speed clips and small phillips round head machine screws to attach the grill slats.

The upper right corner are what was left of the hardware to the sideplates and bottom plates for the grill. Round button flat phillip head style machine screws.

The upper left are the clips and flat head machine screws that secure the top of the grill. The screws are exposed when opening the bonnet and not covered by the thin rubber webbing.

Frank


Frank Cronin

Matthew,

I scanned through the photos I have of this red TF #891. In the picture attached is the Simmonds "aero" nut on the other side of the bonnet. The bolt here is the Simmonds anchor nut on top and is also painted body color -- red. I do not have any pictures of this hardware that attaches the front of the bonnet.



I can not say with 100% accuracy if major engine work was done on this car that would require removal of the bonnet side panels. The paint on these Simmonds nuts look undisturbed and untouched.




Frank Cronin

A cropped photo of the picture above.



Frank Cronin

I will add this picture as well. Clearly the this bolt to the flasher unit is painted red. Why, I have no idea. The flasher unit probably has a cadmium plating to it that is fastened by a red bolt. The tool box is that this flasher unit is mounted to clearly is body color. "Close call" but this sort of throws out the "painted bolt rule" I have understood is that if a bolt was attached to a bracket or another colored piece of hardware, the bolt head was painted the same color.

I went to the Original mgtf midget picture gallery to check out Colin's red TF #6688. If only the camera was just a little to the left or to the right, we could see the orientation of the Simmond's hardware to fasten the top of the bonnet side panels and the color.

As for your picture of your grey TF Simmonds "aero" nut and when I first saw it, as Rod said as well earlier, it looked like to me like surviving grey paint. Cadmium does have whitish, silvery plating. This is a superior sacrificial coating to protect corrosion. In an electrochemical reaction, the plating material will corrode, and the fastener material will remain protected.

In your picture, the sharp corners of the nut are worn but there is either surviving paint or cad plating on the bolt flats as well on the tip of the bolt above the bolt heads.

Since I have cataloged all the bolts and labeled in zip lock bags when I did tear down I will inspect the hardware. My car is the same color as your but not in the greatest condition as yours. Mine was more "tired looking".

In any case, I am only giving my opinion and maybe Colin Stafford can take observe and take pictures of this hardware on his car and hopefully another original car will come to the surface so we can compare. I do recall a thread on a red TF in Georgia that caused quite a stir with the color of the valve color.... (did I just say that???) At least we have another car we can examine.

Again as Rob said, a great opened minded and great discussion on the originality of these cars.

Best,

Frank






Frank Cronin

Darn typo. In the post above this sentence -- "In your picture, the sharp corners of the nut are worn but there is either surviving paint or cad plating on the bolt flats as well on the tip of the bolt above the bolt heads."

should say -- the tip of the bolt above the bolt THREADS."
Frank Cronin

My mind and fingers are not synched to the keyboard it seems.....

Regarding the post on the grill slat speed clips...

"The upper right corner are what was left of the hardware to the sideplates and bottom plates for the grill. Round button flat phillip head style machine screws."

should say -- Round button flat head style machine screws."
Frank Cronin

Rob sounds correct, yes I do have separate build sheets for TD & TF must refresh on them I was working from memory.

I apologise for diverting this body plate thread into a simmonds nut discussion.

This latter topic will be hard to search for in the future
Rod Brayshaw

No apology needed Rob. It's all good. Very good. We're all learning. Although this thread perhaps got off track a bit, lots of excellent significant information on the various topics is being shared here in this round table discussion by enthusiasts in this current thread.

If someone does a word search for “Simmonds” or “aero” nut in the archive, this thread should appear in the search results.
Frank Cronin

I will start a new thread on Simmonds nuts so we can list them all. I found a few more. Great input here.

My photography could be playing tricks, but I can see only traces of cad plating on my nuts.

Cheers,
Matthew.
