What tool actually did the pinning of badges onto vintage frames?
Postby feelthewheel » Thu Nov 15, 2018 10:35 pm
And given the passage of time and updated manufacturing techniques, would any of these still exist (and the pins) or have they been consigned to the scrapheap? Every restoration I've seen so far that's taken cast/pressed badges off for painting has either glued them back on or used modern pop-riveting (which looks either a bit naff or risks falling off due to a weak adhesive bond - and some of these badges are super-rare).
Does anyone have any thoughts/images? Or have the actual tool in their collection? Look forward to seeing what everyone can share on this topic!

I would have gone down this route if I had found a replacement badge for my Pinarello. Alas, I never found one and used a decal instead. There were no holes in the head tube, so it probably never had a riveted badge to start with.
Apparently the original rivets, or drive screws, are hard to find. I bet the rivet press is a valuable bit of kit, too.

There is also a headbadge rivet that you tap in with a drift and hammer. It has a small round head and a twisted fast thread body. I use a largish nail punch as the drift and a couple of taps drives it into the frame and the 'thread' grips the metal. They protrude only a mm or so from the inside (depends on the badge) so you can file the excess off if you so wish. I've got a jar of them somewhere, I'll try and get a picture up. These days I must admit I generally stick to alloy pop rivets and fill the hole with Liquid Metal or soft solder to make it look better.

PS as an aside I have seen brass machine screws used on some British frames, dunno if they were original mind you

Ten minutes work with an angle grinder and drill and we have a headset rivet press. Not something I'd want to use putting 5000 rivets into an aircraft but for two rivets occasionally it works fine. I did a quick test with a bit of tin as a dummy head badge and a scrap frame tube and it worked well. May need a recess in the anvil for thinner badges/tubing.
Go make one!

these pins are called Hammer drive pins, if you google that name you will find many suppliers. Quite commonly used in engineering circles on many equipment that you need to fix on a badge or plate of some sort. have used them plenty of times.
a press can be used, but really there is no need for a special tool, just need a hammer - though if pedantic you could use a punch with a recessed head. The spiral knurling on the pin is designed to bite into the sides of the hole and not easily come out - without any need to pein the back side.
