Ive repaired a few things with superglue and bicarbonate of soda, try it, just put a small amount of bicarb in a small pile and drop some superglue on it. When its set hit it with an hammer, you will be surprised how hard it is.

I'm a guitar player, so I've used super glue for all sorts of repairs. The bicarb trick is commonly used to fill over-cut nut slots (where the strings are supported at the headstock). As bash says, it's s rock hard.
It's also used (without bicarb) as a drop-filler for dings in the lacquer finish. Once dried, you can scrape the glue filler with a Stanley blade then polish to a high gloss finish. Result is nearly undetectable.

I'm going to buy some bicarb and try it! Sounds useful.

We have this available as an "off the shelf" product - comes with 2 colours of filler and plenty of glue!

I find that I'm generally disappointed with the ability of superglue to stick things together....

PM sent. I tried earlier but it seems to have gone missing without ever being sent. Hopefully gets through this time.

It's all fixed!! I had a fun 3 days at the NEC Resto Show, with very welcome help from Alan_M (whose previous experience with dashboard removal was invaluable), Phil (Tanz) (who undid the undoable nut) and Tony (Metblue) removing the dashboard to gain access to the heater box.

The only slight glitch was that I left the heater box in place, and there wasn't quite enough space to get a standard cordless drill and drillbit in to drill the hole in the end of the lever. This was fixed by using my little electric screwdriver instead (having wandered off to the autojumble to find an appropriately sized drillbit with a hex fitting to go in the screwdriver).

Pete's nicely machined pin was glued in place using JB Weld - I needed something thick as the hole was a bit too big so there was a bit of slop to take up, superglue is to thin to fill the gap. Left overnight it was satisfactorily solid the next morning. With the cables lubricated too while I was in there, it now all functions nicely. I also took the opportunity to lubricate the blower motor, which had taken to squealing unpleasantly.

I've got a good picture, but it's only on my phone (and the Grand Tourers Facebook page) at the moment, so I'll move it somewhere I can link to later on...

Also, once I've got all the great pictures Alan took, I'll do a proper write-up of the dash removal procedure, while I can still remember how it went.

Here's a picture of the fixed box, with Pete's machined pin glued in (note I haven't connected the control cable yet!):

Good job Richard! Looks like a neat bond. I like the slow-cure JB Weld.
