Would you like some more pics from different angles?

Some thoughts:Idris wrote:The problem with it being a tool malfunction is that the result still works. The proposal is that a correctly working peening tool rotated and moved up and down. However, what these three-way axle ends show is that the wheels still stayed on without the normal peening. That being so, why would Lesney have continued with the rotational element? Wouldn't it have been simpler (and therefore cheaper) to have rolled out the three-way ends across all models?
I think we do. There is some black and white footage of Lesney's and, at one stage, a model is shown being placed on its side underneath a piece of equipment strongly reminiscent of a pillar drill/drill press. It has always been assumed that this is an axle peening machine.DrJeep wrote:Do we know that the normal tool rotated?
Using a tool designed for spinning as a compression tool (without spinning) would likely break after a few hundred applications.Idris wrote:That being so, why would Lesney have continued with the rotational element?

Thanks George, it is a nice change away from the deciding if a model is fake and good to have a discussion with many good contributions, suggestions and opinions. Sometimes more is uncovered than what was originally thought. I live in hope of seeing photographs of the tooling one day.kerbside wrote:Thank you Bert for doing the research on the 3 way axel, very time consuming I should think.

I am quite sure the tool used to rivet/round/burr the end over rotated because on many of my axle ends the ends have very fine scoring and the minute shavings or very fine metal specs that came off are still stuck to the wheels. No stationary tool that I am aware of could create such particles. They were most likely stuck to plastic because they would have been warm.DrJeep wrote:- Do we know that the normal tool rotated? I think the striations wouldn't radiate from the centre if the tool rotated.
What a difference a few hours can make after reading all the overnight replies and some practical work today I was pleasantly surprised to read Hugh’s latest response. ESP working here.Idris wrote:Just a thought: if we are looking at a peening operation failure, there are two possible modes. In the first, the tool stops rotating. In the second, the tool continues to rotate but the axle is no longer clamped, i.e. it rotates with the tool.
