very very interesting. Many thanks. I just bought a 12t press

That works great. Great idea with the insert

I'm working on an older (similar) crank (1973 RD125) and the manual shows the left and right cranks being separated first with a simple tools which clamp on to the perimeter of each crank and are then pushed apart by turning bolts threaded in to one of the tools. They then press the conrod pins out of the individual cranks. Would this perhaps have been a method used if there was no tube like yours available?

interesting video, im looking to swap out the conrods on a 125 twin for ones off a 200 twin.. but having never done crank rebuilding i looked to see if a company can do it, but so far nobody local cant take the ends off ,like in your video on two cranks to swap the conrods over and rebuild n true .. i may look to do this myself

Can you tell what is the OD of that 10mm wall press tube, I'm guessing 6.6" maybe, x 12" tall with 10" x 2" slot? And the size of the Magnetic V-block is it 4" long?

Here is an interesting view of how a crankshaft production line works, notice how the crankshaft operator uses a solid copper block instead of a hammer, also the large copper drift instead of a hammer, if you use a copper hammer the hammer eventually mushrooms and tiny fragments can flake off that can work there way into and contaminate and or damage the soft white metal big end bearing cage, which is what you want to avoid if you can,

Another superb product in the making,

It is good to see that production is coming back home again, Hotrods USA,
