riveting

Ok someone who has experience fitting their own chain & riveting please shed some light on this for me: please ignore the slight scratching of the links either side, it is surface scratches only because i had to file some links down to cut the chain to size prior to fitment... why the hell...

Any hints on hot to? Tsubakis link is not hollow point as in D.I.D, but it is level and finished work should be "quad riveted" e.g. a mushroom type of riveting. If you have done it please share your experience
