Michael: Thank you for sharing Many questions
What are the gears and where were they sourced?
What is the ratio?
How many teeth on each? They are really big teeth.
What are the outside diameters of the gears?
How are the gears fixed to the shafts?
How much horsepower/torque has been put through these?
What car is this in?
From what I can see the thick plate in the back ground bolts in and the pinion and changes gears are mounted on that is that correct?
Thanks again really appreciated.

Progress to date. The gears and coupler arrived from SCS the gears look pretty stout. I have been working on a pattern and core box for the right angle drive section, the final drive and change gears will be housed in billet plate sections sandwiched to the right angle drive section. Couple of photos attached one separately due to size limitations.

The parts in the cart are the intake faces cut off a couple of flathead blocks I am working on. One I was using brazing to modify which didn't work out, too much distortion, the current build has the block filled with aluminum.

It's kind of a Kiwi trait. We grew up in the middle of nowhere so if we wanted something we'd probably have to build it.

We (kiwis) have quite a bit of Scottish heritage, especially the Mainlanders (South Island).

Scots have deep pockets and short arms so its hard to pay for stuff. Lots of immigration after WWII as well so the make do and mend generation traveled to NZ on a 10 bob (pound) ticket - my father was one of those but insists that the term POM applies to the Aussies, not the Brits as it stands for Prisoners of His Majesty and should be POHM.

Sorry, NZ history hijack.

Even worse..An American doing a Kiwi/Aus. Hi-jack. On FerrariChat.com there was a New Z'er who referred  to Aussies  as "Shackle Draggers". OK Grant, back to you. :cheers:

Flat
Have you considered sprockets and tooth belts to and from an offset shaft parallel to the driveshaft with a conventional rear . Simple and low drag .

Jerry, Sid et al : Thanks for the comments I think one of the many things I like about LSR is that it is a motor sport that is still deeply rooted in a garagista culture so there are all sorts of amazing things going on in garages around the world, it sits well with the Kiwi psyche, but the can do, make do philosophy is clearly wide spread within this community. The build diaries are really interesting and enjoyable to follow.

John: Looked at a few belt drive options but not the idea of a counter shaft, I struggled to find a belt option that would allow an easy ratio change but accept that the counter shaft option would allow that, its a bit moot now as I have hitched my wagon/dollars to the gear drive  :-(.

Progress the miter gears arrived (Photo) I feel a bit vulnerable about these given I have no hard evidence that they will be strong enough the other gears are all proven items. The miter gears are Module 5 and the change gears are DP 6 ( Mod 4.233) so technically they are bigger than the change gears. Anybody who knows about this stuff please chip in.
