A nice clean piece of engineering.

Tanks for the compliments.
It's only possible to do some of these things as I have access to the equipment. Otherwise the alternator bracket would be mild steel which would be perfectly good but not as pretty as shiny stainless.
Anyway things might change as I'm moving job at the end of the month.

So I made more pretty bits.
Master cylinder plate
Clutch cable bulkhead plate
Billet dipstick (with yellow bits)

I'm going to remake the bulkhead plate as it warped and looks crap.

I have remade the clutch cable bulkhead plate and tack welded it at the moment.

The problem is that the clutch cable adjuster thread is now touching the clutch arm. I could cut a bit off but there isn't going to be much adjustment left.

Can't make the tube at the bulkhead any longer as the steel pipe on the outer cable is touching the scuttle.

The lug I welded on to the clutch pedal (to pull the cable downwards) was a pure guess! Looks like it's not long enough as there isn't enough movement of the cable.
I should concentrate on correcting this first. It would probably be easier to work out with the engine running!

I had to lengthen the arm on the pedal by a good 3/4" or so, and cut a relief slot into the top of the pedal box to get enough movement. Mine is spot on, plenty of travel, bites nice in the center and works great.

When you say you lengthened the arm, Do you mean the pedal or the part that pulls on the cable?
Did you work yours out when you had your engine running or were you just lucky?

I lengthened the arm on top to give a longer pull, not the pedal part. It you look at the micra pedal, its arm is a lot longer, and this length is offset by a helper spring. I didnt go the same length as the micras pedal, but certainly made it a lot longer. I was planning on setting it up after getting it running. I set it up by feel without it running, but when I got it all going the clutch just worked perfectly. All my fears were for nothing. 

Ive done over 300 miles in mine now and the clutch works perfectly, and isnt overly heavy as I had feared. 

 

Heres a pic of mine, before I actually made it longer and added the bracing back up to the bulkhead. Will look for the final pics on my phone.

I did mine by pulling the micra pedal box out and roughly measuring the travel, you then have to achieve the same or similar travel. Because the two move over different ranges it makes it more complicated than just having the same lever length.

Cheers guys.

I think this is definitely a job to finish off when I am up and running.

I have also been working on the gear linkage and that's another job to be finished off later. It will be much easier with the seats in.

Plenty other jobs to be done. Most important is the final position of the engine now that the rear engine mount is finished.
It's looking mighty close between the dif and steering rack.
