Thanks Roger and all,

Lokut nuts. Better do some counting and measuring, of the missing and those that are no longer man enough for the job.

Looks like I am going to be spending all my 'mullah' on fixings.

Cheers

Steve

A bag of 50 is about £8 - I think I got mine from one of the Silicone hose suppliers as part of an order from ebay. The 7mm ones ring a bell, and a bag of 50 will pretty much do a whole car.

That's just the sort of information I needed.

Thanks

Dumb question - Spare wheel support plates...And stuff

Post by drcdb15 » Sun Jun 09, 2019 10:28 pm

Has anyone got any thoughts about plastic rivets? (oooh doctor, it's me rivits...)

I've been taking apart all the high tech hardboard panels in the back end of MB61, and found a plethora of screws holding inspection panels in place, with self tappers screwed into the GRP bodywork. When I say "screwed", well, in more ways than one - pretty much all of them are so loose you can almost pull them out by hand, so yet again I ponder what is really the best way to fix things into GRP panels.

On the Webster the builder (or may be OEM?) has used typical nylon inserts with a square profile, which are great for the headlamps which need to come out from time to time, as being square the insert resists turning. But there is the problem of how do you cut the square hole in the first place? (seriously, can you get any sort of tool to cut these square holes in a one-er? Morticer bits I've seen for wood look to me like they'd simply rip the GRP apart).

Then there are rivnuts and various other crimp-on designs which use a round hole, but then these (as on MB61) being round can be almost impossible to undo when the self-tapper seizes into the insert and trying to remove it only turns the whole lot in the GRP, making a sloppy hole even sloppier.

So... I thought, the whole problem here (sorry...) is trying to stop fixings rotating when a rotating screw is used to effect the fixing. How would it be if a fixing was used which doesn't need to be rotated, and hence won't damage the GRP? Rivets of course, which Reliant used so ubiquitously in the first place, but who wants to have to drill out zillions of metal rivets just to remove an inspection cover for five minutes?

Fast forward to today, and we have plastic rivets which cost pennies for a sackful, and you can just cut them off with a Stanley knife and stick in a new one for next to nuppence. The question then is, would plastic rivets and their ilk be strong enough to hold a typical panel in place?

Can anyone offer any experience here, and maybe recommend a particular supplier/size/style/tools etc etc?

Thanks as always for your thoughts.

Can you use spire clips?

I have used these ( or similar ) of various sizes to hold my MB door panels on - smaller fixing along the bottom an larger ones down the sides as I found screws and associated clips came to bits regularly - these have been much better and come in packs of plenty.

To make square holes in GRP, use a square file :D

You shouldn’t use self-rappers in rivnuts.

None of the panels are structural, so plastic rivets would be fine (although I’ve never used them myself).

I've used these before, and they're fine IF you have a handy edge to slip them over AND that edge is the right distance from the hole. On the plus side, you can get them in all stainless (also with just the captive nut in stainless, BZP the rest etc) so you can get a really strong fixing if you happen to need it like that.

Actually it's the one holding the rear wiper motor in place that I had particularly in mind when asking "are they strong enough". That panel isn't just decorative, and needs to stay rigidly in place. On MB61 some PO has already replaced the original self tappers with larger ones, and now there isn't a full complement of those... (note to self: never again buy a car with so many POs... :cry: )

I did 'discover' square files after I'd posted, but even so it's a right fag having to open out each hole like this before fitting the insert - and the big worry is what do you do when you open it out too much? Start patching with more GRP ? No, it's all getting too complicated. I much prefer Peter's 'christmas tree' fixing - drill hole, push in christmas tree, feel smug :D

The purist in me worries about the christmas tree damaging the GRP when it's pulled out. On the other hand, how often do you actually remove these panels in the life of the car? (Too often if the state of my car is anything to go by!). I will get a 'kit' of a zillion different sizes in a pretty tray from China and start experimenting...

Many thanks to all for your thoughts.

I will try and get it repaired I think, its only the little overflow nozzle, so should be able to run a bit of solder around it. Might strip all the old black paint off it and polish it up a bit. Bit of bling under the bonnet
that is what I did soldering is easy and the removing of paint looks better (although its black to help dissipate the heat )

photo of the larger fixings I used on the door panels - smaller ones along the door bottoms - hold the door panels on no bother and come out easily when and if you have to take the panels off

I have a drawing of the front nose plate (I made my own a few months ago and had it welded by a local chap)
Hi Will
Is there any possibility of you sending me a copy of your drawing as I will be having some (3) made in stainless steel?
The laser profiling, bending and welding will be carried out by my very friendly engineering company next door. They produce highly accurate work for JCB and other leading companies. These will be for my GTC’S so may be different but I can easily measure any differences. This is just for me to make my dinner breaks more interesting without having an obvious steel tray sitting on my desk.
Regards
Ron

Ah - you said access panels, that one’s a mounting plate.
