How to make a special holding tool for motorcycle fork disassembly! 

Right, that depends on the fork, there's a snap ring or clip underneath the dust boot and it holds in the seal and maybe a large flat steel washer -- again, depends on the fork -- but once that snap ring or clip is out, you just pull and slam the bush against the lower tube and kind of like a slide hammer, it comes out. If it won't, you missed a step. The video was about the holding tool for that part, not necessarily about fork disassembly. But I hope that helps. The service manual should tell you how to do it.

Yep. Two people can do it without anything so extravagant. Unfortunately, I'm chief cook and bottlewasher and don't have any help.

I have also. It sometimes works. Some of these though, are really stuck. I’ve had to heat a few with the torch.
