Dashboard binnacle repairs

Postby CJH » 09 Jul 2018, 21:40

I've been tidying up my dashboard - I've fitted my PCB to replace the crumbling foil circuit board, and I'm working on adapting a diesel tachometer to work with a coil pulse from a petrol engine. So I've retrieved my original binnacle from the shed, because I will no longer need the knob in the middle of the right-hand window to adjust the clock. But my original binnacle has some issues - just like every other binnacle I've ever seen!

A couple of the corners are cracked/broken, and won't take a screw.
Image

The mounting tabs on one side have both snapped off.
Image

And on top of that, a couple of the screw holes in the corners of my speedo have broken.
Image

To fix these various bits I've been making repair pieces using AutoCAD and my 3D printer.

First off - a repair piece for the broken binnacle corners. I made a piece that has an integral screw hole that can be glued to the outside of the binnacle.
Image

To fit this I first needed to tidy up the broken corner. So I marked where I needed to cut away some broken plastic...
Image

....then I Dremeled away the broken plastic...
Image

...and finally I epoxied the repair piece in place...
Image

Next up - a corner 'clamp' for the broken corners of the speedo. I designed it with an oval screw hole so that it would work on an unbroken binnacle corner and also on one where I've glued the above repair piece to the outside.

Image

Image

This part doesn't glue in place - it just screws down and clamps the speedo corners in place.
Image

Image

Image

Finally, I made a repair piece for the binnacle mounting tabs. The mounting tabs are on a slight curve, so the repair piece is simply a clamp which stops the binnacle from moving in any direction. It should work no matter how much of the original tabs has snapped off. The original binnacle self-tappers aren't long enough to secure the clamp, so I've ordered some slightly longer ones. I've made the stepped section thick enough so that the screws can be done up nice and tight without putting any stress on the binnacle plastic.

So if you see someone at Busfest snapping up all the broken binnacles, that'll be me, looking to rescue them with my repair pieces!

That’s brilliant! Any chance of making me a set of the ones for the mounting tabs?

I was looking at these, your solution looks much better.

Sure - I can run another set off. How does £5 for the pair sound, plus £1 postage? The other parts I could do at £1.50 each, but the tab clamps take MUCH longer to print - about 90 minutes each.

There's actually a couple more pieces I want to make. They're not needed for my binnacle, but if the binnacle corner near the mounting tab has broken, or the speedo frame on the same corner has snapped, then the full corner pieces won't fit because of the mounting tab frame.

That will include 4 of the longer self-tappers.

Brickwerks do a similar simple catch that holds the binnacle on the dash - simple but effective (Absolutely LOVE your version of solving the problem 1980's German plastic obviously didn't have the "lasting" factor built in ;-)

I'm sure you will have seen these http://www.gowesty.com/product/bundles-and-kits/24612/instrument-cluster-corner-repair-kit already - they'd be much easier to print. Actually no use to me. Corner is still there its the other part thats broken

Mine wins for having deteriorated more - this is 1982 plastic :) I’d go for the corners as well except I’m afraid to disturb anything because surprisingly it all still works at the moment.

If you could print the whole thing it might be better :)

Actually I hadn't seen that. The little crescent shaped part would be marginally easier to print, but there isn't much in it actually - the vertical 'walls' on mine don't take long to print, and I think they help to locate the piece so that it doesn't lift or turn when you tighten the screw.

You'll have to be more specific! That GoWesty kit has a part for the binnacle corner and a part for the gauges corner.

How about I finish off the parts for the last corner, then do a post showing all the different parts, and I'll try to give them sensible names so that you can specify exactly which piece(s) you need.

If you can do me a sketch with the necessary dimensions I'll be glad to have a go. Do you have a photo of an original part, and/or a photo of where it fits?

Piece of cake. You can have any colour you like, as long as it's black or white. But I suppose you're going to want it in brown.

Is that 12.8mm internal diameter small enough to make it a nice tight fit over the bolt?

Scan reading as usual. I hadn't noticed that it had both. It's the right angled piece I need.
