FridgeFreezer Posted June 13, 2021 Share Posted June 13, 2021 I've got a manual lathe and a CNC mill and I can totally screw things up on either of them equally well Great work as ever. 1 Quote Link to comment Share on other sites More sharing options...

Jamie_grieve Posted June 15, 2021 Share Posted June 15, 2021 That's looking fantastic, it's a bit late now but would the diameter of that pinion shaft lend itself to having the 16 splines of a propshaft slip yoke cut into it? I ask as a Discovery or range rover solid front prop has a very convenient yoke that could be used potentially adding an inch or two to propshaft length in builds where the prop length is marginal. 1 Quote Link to comment Share on other sites More sharing options...

Thanks absolutely no idea with the slip splines one thing I have discovered is that the mog pinion is very hard HSS cutters will not even scratch it and the tipped cutter I'm using was the only one I could find that was narrow enough to do the job so I would probably have difficulties sourcing a smaller tipped cutter also the one I'm using is 11/4" bore and bench top mill table is 1" so I had to make a holding bush for it, the joys, I guess no build is straightforward but I seem to be spending about as much time making jigs and rigs as I am actually working on axle mods but it will be worth it in the end regards Stephen 1 Quote Link to comment Share on other sites More sharing options...

I'm rough enough not to hesitate to put a grinder in the tool post that would have a real machinist horrified. 1 Quote Link to comment Share on other sites More sharing options...

No, the whole lot is very hard it's actually hammering my cutting tool to death but I have a plan. Up to now I have just been extending the splines because it is easier to set up when the reality is I'm cutting material I don't need, because I'm going to chop 5" off the end of the pinion, so why cut what I don't need. The plan is to take pinion out of mill and set up in lathe and turn down most of the diameter I don't want and only leave a bit at the end to set cutter up against then the cutter will travel across the reduced area and cut only the section I want this causing less distress to my cutters hope that's clear enough, future pictures will explain better regards Stephen 5 Quote Link to comment Share on other sites More sharing options...

Just to add to this I have been checking out tool cutter grinders, how expensive are they really only havnt got one as yet because you can buy a lot of cutting tools for several hundred quid and of course I've only had my milling machine for a couple of years and my lathe two years longer, both of which were bought to assist with mog axle conversion, not that I'll be getting rid of them once the axles are finished lol Regards Stephen Quote Link to comment Share on other sites More sharing options...
