Too late to do the maths but +/- 0.4mm looks like the tolerance for the diameter of laser masts

Is it even a custom extrusion?

That’s from the EN standard and I would say it would be hard to improve on. Only ever seam the process once but pretty awesome. A very long hall, the extrusion comes out of the die very fast, at some point a sled grabs it pulls it to stretch it and cuts it. All very fast, it is a high volume process.

Nominal is ~ 1.5mm thickness so +/- 0.4 is biig for boat spars. I think you can influence the range by replacing dies more often but that adds cost.

I'd be pretty surprised if it wasn't a stock tube...

That a what i'm thinking. So all the talk of die wear is irrelevant. Its not going to be extruded to especially high tolerances but on then flip side once these tolerances are exceeded the die will probably be replaced and because they are making kilometres of the stuff its not a financial drama to do this.

Just noticed that a Laser/ILCA 7 with covers, trollety etc will be near£7.5K
Initially a bit shocked but I guess its half of an OK or a quarter of a Finn now ? So, despite the low tech etc its a very good buy to get racing ? Remembering that in the 90s you could get one for £2K ish |

And in the 70s about £400!
