I had a machine shop turn a mandrel for me. Cost $10, but that was decades ago (and I have no idea where it is today). That, plus some 3/4" threaded rod, nuts and a flat bar with a 3/4" hole was enough to build a suitable substitute.
The rearmost bearing is particularly tricky, as it's the only one that has a front & back (even though the 3 bearings are identical). IOW, the middle two bearings can be installed with either side to the front, but the rear bearing must be turned correctly or it will block the oil feed to the rocker shaft.

Outside of the really basic stuff, it seems as though every "involved" task I give the local shops gets mucked up. Like the aforementioned oilway. Or the oil pressure relief valve on my MGB-GT a couple of months ago (you do NOT want to try to change that bad boy whilst the motor is in the car)...anyway, would like to eliminate that kind of stuff by doing more myself.
Was hoping there was a commercially available tool that could be somehow modified.
Your home-made version has me thinking.....
Thanks
