The Mounting tension.

This week I have mostly been making the overdrive mount. This has required my most bestest 3D thinking. The mount needs to attach to the bottom of the overdrive adaptor, and then attach to the gearbox mount on the chassis.

So I made up a jig, using the old gearbox rear extension to mark it out.

Lined up the mounting holes with some pieces of wood for a datum.

And put some screws through the jig to capture the position of the flange. Then it was a simple matter of putting the overdrive adaptor onto the screws and building the new mount around it.



Zap zap with the welder and - hey presto, one proto-gearbox mount.


It's not finished yet, but its a good start. It needs lots more welding and the right hand side looks a little wonky (I'll check that out later). I've also been having a crack at sorting the overdrive wiring. And that was a pain, and it doesn't work properly. The spare solenoid doesn't work and I couldn't get the switch to do the right thing. Its supposed to toggle the solenoid on and off (returning to the neutral position in between). But it didn't do that so more work is required. To be honest, I'm not that bothered, I might even stick the gearbox in and roll Jessica like that and sort the wiring at a later stage. But then again I might not...

Molly has had a little attention too, I've been over the wiring again as the lights packed in - new loom required I think. I have changed over the fuse box too (2 fuses - cool) which might improve reliability a bit... maybe.


Nice to see all 4 wheels on the ground again. The todo list is quite short now. In fact I have to think quite hard before coming up with anything concrete.... I need to change the front offside wheel.... and bleed the brakes..finish off the seatbelts.... Is that it?

Impressive work on the gearbox mounting. :)

its a bit agricultural, but the theory is sound I think....

the proof will be in the pudding I recon!

nice proto-gearbox mount - looks like the rear spoiler for a certain DeLoren...

Hey Rupert nicely done with the gearbox mouting brkt like your jigging concept.
Molly is looking good now I bet you see light at the end of the tunnel.
gearbox - gears = gearless gearbox

Hi Richard, yeah its all coming together nicely now, shouldn't say that really - inviting trouble! As far as molly goes, that's not light at the end of the tunnel - its a broken commer!
