A Tale Of Two Sprockets .............

[colin400four]

Hi to all,

as you all know to try and find a new rear sprocket with an original gaurd fitted for the 400/4 is pretty difficult, so I came about this " used Sprocket " which looked like it had plenty of life left in it, but still classed as usedand tatty, SO, out came the paint and I "tarted " up the sprocket and guard.

Not bad I thought, but still a niggling thought that no matter what I did it was always going to be a used Sprocket.......... see first set of pics.

So, plan 2, get a new after market spocket, an old guard, restore the old guard and then rivet the gaurd to the new sprocket, Looks o.k and now with a new sprocket  see second set of pics

How did you rivet it up without chipping the paint?

Thans for the kind remarks,

With regards to the rivets, I had to use 5x16 mm rivets, big buggers, which on a test piece broke my crap cheepo pop rivet gun, didn't help I guess as I was asking the gun to "pop" a size it was not made for , so I invested in a big bad lazy tongue pop riveter and this did the job with no problems.

With regards to chipping the paint, the way that you insert / pop the rivet, all the force seems to be taken on the actual rivet face , and the way you use a lazy tongue riveter as apposed to the little hand held riveters gave a much easier way to pop the rivet, (didn't need as much force ) so chipping was not a problem.
