Scratch built GT40 finally running
Discussion
Thank you for the kind words Paul. Yes - it is noisy. My partner wears ear defenders. I turn my hearing aids off and they act as ear plugs. My final drive is lower than in a Le Mans box, so I'm at 2500 rpm at 70 mph.
It is indeed fun to take on these trips, and we are always joined by some other wonderful machinery. You would have appreciated this.

Absolutely gorgeous. For a second there I though you had a second one with number 99 on it!
Please make sure no rodents can nest in there, I had a rat carry a Tux dog biscuit up into my engine bay once and when it had half eaten that it then proceded to chew through my wiring loom at the bulkhead

Thanks for the heads up, but I have rodent control all sorted.Please make sure no rodents can nest in there, I had a rat carry a Tux dog biscuit up into my engine bay once and when it had half eaten that it then proceeded to chew through my wiring loom at the bulkhead
What an amazing car and road trip!
I did a lot of those roads while travelling in NZ in Dec 2019, unfortunately floods and landslides blocked the roads around franz josef. I thought the weather changed quickly here in Scotland but NZ was something else!
Hope to go back some day and do another tour but hopefully in something a bit sportier than a Land Cruiser.

Took the 40 out for a test run today with the Otago Branch of the Vintage Car Club. Wanted to check out all was in order after the winter maintenance programme and before embarking on the Avid 2000.
All went well apart, from some brake pad rattle, which seems to have been a feature of the car since we finished it. May give some CRC Disc Brake Quiet a try. Only work really needed was to adjust a tiny bit of play out of the front right wheel bearing.
Route for the Avid 2000, which starts on Thursday.

That should well and truly take care of any cobwebs, looking forward to the photos 
Any chance of more videos? The shakedown video (on page 14) from a couple of years ago is great, but now that you have a lot more seat time would love to hear it in full song out in the wild.
Really appreciate the thread updates, it is brilliant seeing the miles rack up.

The trip started out fantastically with clear blue skies.
We were in company with 65 other interesting cars, covering some of the best driving roads in NZ.
On day 2 the rain set in, but we got the GT40 in to Milford Sound.
The fiord is always spectacular, and even more so in the pouring rain.
However, on the way back to the evening base the clutch slave cylinder let go and we had to limp home, then get the car trailered back to Dunedin the following day. Very disappointing as it was a part I had only recently had rebuilt.
All was not lost however, and we were able to rejoin the tour in the ST205 GT4, which didn't look out of place among the more exotic machinery.

Replacement parts have all arrived and transaxle casing machined to accept the new, more robust, dash-2 clutch release shaft. New clutch release lever installed and safety stop added as a precaution (initially relied on just the pedal stop inside).
Gradually getting things back together now (bell-housing on, starter installed and wired up, transaxle back in). Hopefully have it running before the weekend.

Looks like that should fix it for good, however if it happens again it looks like there is the opportunity to sling an outer support bearing off the bellhousing bolt just above (inline with the release shaft axis). The previous failure looked like the breakage originated at a stress concentration on the spline so an outer bearing could help take the bending component out of the slave thrust.

Thanks. Yes - that is an option. The guys at Leitch Motorsports reckoned the old shaft looked as though it had not been heat treated properly. New shaft is thicker, so should be stronger. Time will tell...
