Looking to cut'n'shut a Datsun L-series bellhousing onto a Nissan S15 6 speed gearbox.
I'm intending to make up a jig consisting of a mandrel that bolts through the main bearing caps of a spare block and continues through to the input shaft bearing / bearing recess in the bellhousing to keep it all aligned. The L-series bit of the bellhousing will bolt onto the rear of the spare block, and the bellhousing bit from the S15bellhousing will bolt onto the jig via a plate welded in the correct position.
Then take the whole lot to someone for welding.
Anyone see any issues / improvements / etc they can suggest ? What should I look for / ask for with regards to getting it welded up (my welding experience finishes at oxy/acetylene) ? Its been suggested to me that I need to pre-heat the lot prior to welding ? Anyone suggest an engineering place in Newcastle that would be happy to do this sort of thing ?
