Round Speedo for a Fiver
jonti - 21/3/04 at 06:30 PM

Some of you high tech types may scoff at this as a bodge and my apologies if it's old stuff that I've only just stumbled upon.

Anyway.....I think I've hit on a super cheap way to get a nice Round Speedo using the standard Sierra module and ANY old 100mm DIA clock.

I extracted the speedo bit out of the Sierra Intrument Pod (see pikkie in my archive) then I got an old speedo and cut the bezel off about 10mm fom the end. (I had one in my bits box but you could get an old knacker from an autojumble for a fiver) and, as I said ANY 100m DIA clock will do.
This was then sprayed matt black and affixed in the hole in the dash with three tiny screws and copiuos amounts of araldite (also see archive). The Sierra Module was then fixed to the back of the dash held by four clips over the edge of it and screwed.

Say what you like but I think it looks ok and it cost nowt.(true LOCOST ) Plus its the standard car instrument which should please Mr SVA.

Shame the other clocks cost nearly £100 !!!!

Cheers

Jonti

no arguments with that jonti, ive squished the old speedo into a tight hole in the dash, didnt think to get a bezel for it but thats any easy way to tidy it up.


Kitlooney1000 - 21/3/04 at 08:26 PM

problems is that the bezel you have used doesnt look like it will pass thr SVA radius test. but i might be wrong. bloody good idea though


gjn200 - 21/3/04 at 08:30 PM

er I think odear!! I've got a racetech gauge and the bezel wont pass SVA. Admittidly its hard to tell how much its recessed in the padding from your pic.


jonti - 21/3/04 at 08:59 PM

Speedo and Tacho are well recessed actually you can put a straight edge across without touching the bezels.

You're right though, the racetech ones do stick up a bit.

Thought I might make an additional, sort of padded 'mask' to fit over all of them for SVA if I needed too though.

Nice one, my smiths gauges don't meet MR SVA's approval. I was thinking of moulding some rounded bezel covers using black silicone or car filler.

Not worked out exactly how to do this but making moulds from plasticene or clay would seem possible. Or even allowing the car filler to go off enough to be workable like clay ? Rescued attachment bezel.JPG

Why not just fit the guages into the exempt area, which is anywhere behind and to the right of the steering wheel ,and an amount i cant remember to the left of the wheel of about 120mm.

I thought about getting a sheet of black squidgy rubber mat and making a mask to fit over the intrument cluster with holes cut slightly smaller than the bezels. this could be stuck on with double sided tape then peeled off after SVA.
D'yer think it might work ? Or is this just a cynical dodge of which I should be ashamed ?

I'd need a bloody big wheel to cover that lot I fear !

You should be applauded


Fifer - 22/3/04 at 01:56 PM

I like givemethebighammer's idea. If someone could make something like this in various diameters with the correct radius on the face and a groove on the back to take most sharp bezels, these could be stuck on for the SVA man then removed (or not if they look good !) after test !


jonti - 22/3/04 at 08:02 PM

I agree but they'd have to be bespoke I think....
No two clocks manufacturers seem to use the same bezel.


stephen_gusterson - 22/3/04 at 09:03 PM

i have some nice guages that have illegal bezels.

I am gonna make up either a plastic cover sheet or use the padded idea.

Bought some black silicone today, think I may have ago at making some covers this weekend..... or making a right mess, whatever I will keep you informed !!!!


jonti - 22/3/04 at 10:49 PM

Be interested in seein' how you get on chuck make sure you let us know...

Wonder if there's such a thing as half round self adhesive rubber strip ?

Boat chandlers maybe ?....mmmm.......might check that one out.

You might want to look up the thread I posted on this search for 'Smiths Instruments'

The moral is put they car through SVA with a minimum of dials and switches all in the "safe zone" and add extra dials after SVA.


James - 25/3/04 at 02:31 PM

Looking good Jonti!

Britishtrident,

Just out of interest- your profile's a bit sparse- what are you building? Locost? Kit? Or still deciding? Would be cool to see some pictures.

Cheers,
James

Update

Tried to mould a new bezel from body filler using plasticene as a mould.

New new bezel came out the right shape and looked OK, except the plasticene has stuck all over it and looks impossible to completely clean off without breaking the new bezel. Pain as I was intending to spray the finished article matt black.

So... looking for something better to make a mould out of, I have thought maybe clay ?


James - 16/4/04 at 09:58 AM

What about modelling putty?

Back in the day I used to use some stuff called 'Milliput'. It's two part and lovely to work with. When hard is file/sandable if need be too.

It wasn't barry bargain cheap but cheap enough! Local modelling shop should be able to help you.

HTH,

James


ned - 16/4/04 at 10:42 AM

how about putting a thin layer of grease and some cling film so the stuff doesn't stick to the mould. Not a tried and tested combination on my part, but there must be something that you can use to stop the mould sticking to the workpiece.

DaveFJ - 16/4/04 at 12:17 PM

How about using Flexane? it's a rubber compound available from Frosts and as long a your 'mould' has some release agent (wax?) it gives a really good result.
