skway riveting

<< < (2/10) > >>

oberonspacefruit:
why are they tapered, and to which end?

fischflo:
Good question - as to which end (i.e : how to remove old rivets):
I think i read somewhere that the right side to drill the caps of the rivets is where they are untouched/original/flat, NOT the side where they seem pressed.

Seems illogical though to me :crazy2: ....shouldn't they look pressed on the slim side of the conic/tapered rivet...? "help"

here's a pic of an original rivet .....and some info in that thread about the machine (TAUMEL spin riveter or smth like that)

looptail on the museum about how to remove the rivets:
Take a centre punch to the centre of the rivet head. Drill out starting with a small bit, say 1/8. Then gradually use bigger ones until the head comes off onto the drill bit, making sure you dont use a drill bit bigger than the pin itself. By then you should be able to punch out the pin. Patience plus a good hand!

waza there says: "use a mill with an 5mm end mill"

That's a fair comment Marty. It would be nice to have the know how and tools to sort the hubs, not as a business tho.. It,d beat the filed down nuts n bolts trick some people have done which does look good for show builds..

And the postage to Oz or usa is ridiculous.

Tapered skyway bolts? Is that true. ???

my guess is the top pic shows the pressed side = the flat side = the slim side of the rivet = the side you need to drill off (in order to get the rivet out without cracking the mag)

someone please clear us up for us :-\

Fischflo, good find! I read that too.. The Taumel machines look rather pricey tho don't they.
