OK, looks as though Delco model 981707 has the parts in it that I need to transplant to make this radio 12 Volt.

There's one on eBay right now that I'm going to try convince the in-house accountant I need.

 

This month has been horribly expensive and painful, however.

I'm having a think about that yet needs to be completed to make the car run.

The gearbox bands have to be set with the engine running, in gear, against the brakes.

 

I'm thinking I should be able to put the propshaft back on, turn it through 90 degrees and have it force itself against the floor?

The engine generates 230 lb/ft of torque at max throttle at 2000 RPM. The gearbox will quadruple that in first gear, the prop is about 6' long. I'm thinking that's going to be about 150 lb of force at the end of the shaft max which should be enough to be stopped- it's not set at maximum torque anyway, just high idle (700 RPM).

 

Then cleaning and painting. Steering box.

 

Engine refit.

 

Rewire.

 

That's pretty much it. Not a big list but one with some fairly in depth requirements each.

 

Summer may still happen.

.... Do you mean cradle mount engine + oil drum cooling rig?

The front of this radio was looking a little worse for wear. I took it out to the garage for a little TLC.

Buzzed it down to bare metal with my little DA, fine grit.

Painted it up in satin black, as it would have been originally.

 

Better!

Front panel screws were horrible. Coated them in copper.

...and then in nickel.

Then the front panel all back together.

Cleaned the knobs up and reassembled the fascia.

 

Looking good now.

The cone of that speaker looks rather sad. Top job on the rest of the wireless though.

That looks ace, I bet you cannot wait to get it installed.

The cone is in remarkably good shape. It's all still in line. There's a few stains on it that make it look kinked and warped in the picture. It doesn't buzz or click and still sounds pretty reasonable.

Surprised that the original finish wasn't Black Crackle Finish.

Still "Vauxhall Viva la Difference!" as they say in Luton...

Phil when you're done can I post you an Invacar for your next job?

 

Great work as always.

No, just plain black. Don't forget, most of that will never be seen, only the chrome bits stick out of the dash, the rest hides behind the big circular grille in the center of the dash.

I need to make up a foam rubber shroud for it also, to direct the sound out of the grille,

I have, somewhere, a sheet of the board like material you make PCB's from. I need to rebuild the connector blocks for the headlights.

 

Just need to find it because it's Somewhere Safe right now.

you forgot or the boss put it away :D

I just can't remember where I put it. It vanished during the house move last year.

I'm not looking forward to rebuilding this right at this very moment in time.

if its any condolences, I still cant read resistor colour codes...

 

(well more I cant remember which colour is which resistance etc)

Posted

That's a hot mess; is it susceptible to having a sub board made up to replace some of it?

Posted

Color codes aren't a problem. What is s problem is the thing is arranged in multiple layers of components, all placed in a rather haphazard way.

Possible yes. Any real point to it, no.

 

It's internally arranged in a fairly sensible way, it's just going to be difficult to pick apart and remember what goes back together where.

 

I'm glad I have a digital camera.

You can lie to us but not to yourself. Admit it, you love this shit. ;)

A quick reminder, if it were needed, of how much of an advance the the advent of the transistor and the PCB was.

Yup. If nothing else for power consumption.

 

That radio draws 7.1 amps at 6 volts.

My little portable Roberts transistorized radio from about 15 years later it's still on the same PP3 battery I put in it last year. It's meant to have a PP9 but you can't get them here. A Silver Seal carbon PP9 would run the radio for about 3 years.

 

It still works, even after having been dropped.
