No don't think I need to do that, my plan is to finish off the pinion shaft modifications and use that as the alignment tool, the shaft will be easy enough to protect from weld spatter so I will tighten up the taper bearings tight enough where it has clamped the two halves but still in a position to turn and check freedom of movement. I will support the "pinion clamp" with something a bit more substantial, maybe even hold it in my press until I'm satisfied the initial welds have fixed it into position. Then I can weld, test movement, weld etc until welding complete. I have had success with cast iron welding on smaller projects in the past with good results but, nothing as critical as this is going to be , but nothing ventured nothing gained regards Stephen 

Sounds like a good plan :D

Bit more machining this morning and that's the lathe side of things done on the pinion

Shaft down to completed size

Removed and one of nuts put on and shaft re- clocked in with dti

First cut of threads

Threads complete and nut test fitted, very happy with the result as that's the first time I've cut threads on a lathe in anger so to speak, now I need to suss out cutting the splines in regards Stephen

So my vee block jig contraption is to big for bench top mill gonna have to get some smaller vee blocks 

20210602_150155.thumb.jpg.b745a13a5a0b212b6b16162909167b71.jpg

That got me thinking I dont need splines in yet to set it up for welding so diff built back up seems to have gone back together ok up to now

20210602_145939.thumb.jpg.18140ceb30e697f05556d2c0c7a5d6e9.jpg

I'm thinking of cutting some steel  and welding it to my work table and clamping down on cast sections of diff to leave shaft turning freely  and be able to check it through the process, I'm also thinking if I clamp this into one corner of my bench I should be able to access all areas

That's it for today need to track down some small vee blocks and more importantly feed the dogs regards Stephen

@Anderzander Diff clamp!! Lol 

First some steel 5" channel and 30mm square bar  drilled and tapped to m12 with my Ross wouldn't approve taps from Lidl

Welded together

Ran some m12 bolts down with die nut

Welded onto my bench and diff clamped regards Stephen

Clamp release time

20210604_172414.thumb.jpg.45f7188f6b6a45134b40459cbf58a7a5.jpg

The good news, it hasn't fallen apart, there is no obvious cracks and I can turn pinion by hand very happy regards Stephen 

 

just to add diff casting length is now 190mm it was 317mm regards Stephen

It seems like Dann only shared the picture a few days ago ... and here you are welding it up. Remarkable.

A month on tuesday, had to have a go, there's always the danger I could have talked myself out of it lol Regards Stephen

Next step, clamping it up again and build up the weld?

Definitely build up the weld, but not clamping only doing short runs in different areas to keep heat down until all built up obviously testing rotation as I go regards Stephen

Reckon you could end up with as much weight in rods as original casting at this rate 😉

Sshhh don't tell Ross, he'll have a fit lol Regards Stephen

5” ! 

5" out of diff and 1 3/4" off pinion length, makes a hell of a difference to prop shaft length, a!so using modified front radius arms that are longer than trailing arms, so either axle or pivot end to alter also if it's axle I gain a bit more prop length regards Stephen

This welding up is taking a long time about two rods per half hour so the heat does not build up

20210605_152023.thumb.jpg.711dfcbf764225d6ce5bb8480777ab1f.jpg

Also constantly moving diff to stop heat build up in one area along with altering diff angle to get optimum welding position

Some thin walled pipe over shaft doing its job but so far so good no cracking regards Stephen
