all going for cleaning tomorrow so I can then weld it up.
Just out of interest, if I was to offer this machining/welding what would someone be prepared to pay ?
All i would want to be the two front half cases empty, I havent got the time to be stripping filthy gearboxes for people lol

Nice, you clocking up the bore in the skyline box then using that as a datum on the mill to set the hole points out on the ford bellhousing before tacking together?

see below
the flywheel was already made to take an AP clutch, i used it in my last car.
not sure whatyou mean by bushing the bellhousing, if you mean for input alignment, I have had the input shaft fitted and a very tight crank bush fitted to hold the input front case inlign all along, and will still be in whilst welding.

This is going to be a good thread mate. Followed the fella with the xr4x4 on his conversion .
In terms of the input shaft how much shorter is it needed to be than the v6. Because from what I can remember it was a bit tight for the amount of spline left on the shaft. But by the looks of it you gave no problem as the clutch is there.
Also how are you going about the release bearing arrangement?
I have been researching alot on this as I will be doing this myself sometime soon,
well when my funds have stop being sucked up by my misses for our wedding. Lol

the 4 pot vs the 6 pot inout is about 20mm shorter, i dont know the exact comparison as to how mush of that is into the crankshaft, though from the looks of it i would say quite a bit.
The skyline input shaft has a very short run of splines, compared to the ford input shaft, but im pretty confident i can get a set of tripple plates on it.
for me, clutch release will be a concentric cylinder, but no reason why a std 'push' skyline system couldnt be used.

If you bushed the bellhousing dowel holes and re-machined them after welding using the input shaft bearing hole as a reference you can ensure it's spot on.
Easy way to check is sticking a mag base on the flywheel and running a DTI around the input shaft bearing hole in the case after the welding is done.
If there is no more than 0.004" total variation it should be fine, any more and it would be worth bushing the dowel holes.

what spigot bearing are you using aswell as flywheel or have i missed that?
as the skyline input shaft is a lot larger in diameter than a cossie one, so did you machine the input shaft diameter of the skyline or use a different bearing in the end of the crank?
i for one will be very interested in this if you can offer this service

Sounds like you will be pretty close, but things do move around when welding.

If I bush the dowel holes then I wouldnt be able to bolt it up, thus removing two points of location for pulling the case to the block, plus the cool down period will be very slow, the case will be - de-heated to prevent stress on the welds.
ther will be a good couple of hours welding to be had!

I had the cases cleaned so we had all the oil off, but there is some sort of zinc coating on the cases, as we started to weld we realised this needs to be removed.
But all in all well pleased with the result.
As the first one we have done (the prototype lol) I have no doubts it will be fine.
there are a few things I would do differant if I did another, differance in the prep, and the filler but, well happy !

I'll build the box back up now, and then start the fitting.
But all in all well pleased with the result.

looks great mate, lets hope when you launch hard the whole gearbox doesnt break free and spin around the engine! (only joking!) Great craftmanship there, did it move around much? or is everything pretty much still inline?
