If you've been following this, I decided to shorten the dual gearboxes as toyota in there cheap manor cop'ed out on design and left alot of wasted space in the rear of there G52 gearboxs
I'm fixing that!!
So far I've cut 100mm out of the rear case and milled the end piece ready to weld up the the front part once I have the shaft all go and am able to use the shaft to align the two halves
For the shaft what I'm doing is removing 5th gear in my second box as this isn't needed (gives me a way to high ratio that I'd never use! ) so I've lathed its spline off and cut a new output spline in its place (there's just enough meat to do it
)
To do this I've had to make a arbour to hold the specail grinding disks
long story not worth going into again 
after all that and a simple jig.... I've finished cutting the spline.... and it works!!! 
a little bit tight but not bad enough to worrent regrinding it
Heres a pic of the shortened shaft and female female joiner sleeve and the part of the shaft I've cut out... I've removed a total of 110mm in the end
you might notice a couple of blue dots on the sleve... this is non-splined area inbetween the two shafts (gearbox main and transfercase main) and has me seriously thinking about making a new sleve that dosn't have this... if I do make a new one it will shorten things up by another 35mm
As it stands with just the shortened shaft and clocking the dual gearbox adapter plate I've reduced my drive shaft angle down from 30deg to 25deg which will allow me to run a DC jiont but it will wear out fast as its pretty close to its max
Its late enough now so I'm off to bed
Cheers Reece
