I'm really struggling to get this job done.
I've not been able to find much in the way of a rivet snap for semi-tubular rivets on-line and the ones I have found seem designed to fit in a mini press which I think are actually for brake linings. They are also quite expensive for a one off job.
People have mentioned eylelet tools but just going by the pictures on e-bay the form looks as though it wouldn't work on the thicker wall of a rivet. I tried various local suppliers in the hope of being able to have a close look at the form but all they have are eyelet pliers.
I tried using a large centre punch and then following this up with the domed head of a coach bolt and finally a flat ended punch made from a large diameter bolt.
The results look a bit messy although no worse than the ones I removed but the rivets aren't tight.
I have hit them much harder than I felt should be necessary and even tried a using a plain hemispherical rivet snap I happened to have to see if I could get the swaged out flange created by the coach bolt to curve back and contact the pressure plate but whatever I do there is still axial movement of the rivet.
It almost looks as though the hollow portion of the rivet isn't deep enough but I don't have any way of altering this.
I'm beginning to think that with the very limited equipment I have available I'm not going to get a satisfactory result.
Any advice or does anyone know of a company around South Devon who may be able to do this for me?
John.
