Whoo-hoo! ........ and you said the TÃœV were difficult to deal with.

Mmmm, black, brown, red, orange, yellow, green, ???, ??? grey, white. Violet's in there somewhere. Told you I didn't remember.

Oo-er, it's very green!

But where's the 12v power source to run the electrics and heat it up on cold mornings?

Same colours, different multiplier. Just as well I use a multimeter to test the value of resistors these days, to be perfectly honest I'm not even sure I remember the colour code.

Fancy looking bike, the one leaning against the car!

.... or even a Quiller Memorandum.

Cheers, I'd considered adding a chamfer, as in the first attempt, but the MGF rotor hasn't got one so I elected to specify the larger 66 mm straight sided centre hole. Thanks, putting a radius on the internal corners is something I would never have considered. Given the cost of labour in the PRC I'll leave it up to the supplier to decide how they want to make them but I'd imagine that machining them out of a billet may be the most cost effective option for a small run of 10 rotors.

Looks good Nick, if I were ever to return to England permanently that's the sort of bucolic setting I'd want to live in. I will be enjoying the "delight" of moving on the 26th of November. Will post images of the shed then, before I fill it full of junk necessary equipment, tools, a thousand pieces of Triumph Spitfire and an eclectic assortment of sundry, often duplicated, spares.

The latest and with luck, the last, version of the rotor diagram. No "Title Block", sorry John and somewhat different from the Brembo diagram, thanks MotoV8. I think I've included everything that needs to be there. Scale approx 1:1. Pick away!

I don't care what you say you can't beat a good electric fan! ....... and you were so close Nick. Welcome to Sideways.

Welcome indeed!

Thanks guys, I'm taking your comments on board and starting a new "improved" drawing. Hopefully I'll get enough information into it to make it idiot proof. More as I get closer.

Vielen Dank.

With regard to the "Title Block" are there any metallurgists, or just plain knowledgeable folk, out there that can tell me what an "everyday garden variety" disc brake rotor should be made out of?

All good John, thanks. I drew the countersunk holes in the side view like that because I thought it was supposed to indicate what the top view would look like if sliced through the middle? I would have added the stud holes but it would be more messy than it already is. The plan is to make the drawing "foolproof" so any Chinese machine shop could follow it and produce what I want first time. Nit pick away! Cheers. J.

Modified drawing: The MGF standard centre hole is not recessed, to make it a little easier to machine I removed the recess shown in the first drawing. This is basically a Mazda MX5 NA 231mm rear disc with MGF drilling.

Only one choice! Whoo-hoo!

Thank you gents.

I'm investigating the possibility of having some custom disc brake rotors made in the PRC. What I'd like to do is provide a "proper" drawing of the rotor that can be followed by a manufacturer. My problem, and why I need help, is that I haven't the foggiest idea of how to set the drawing out or label the key features. This is what I have so far, any pointers?

I hope you were working on the car today.

Gerrit-Jan of Volvo 340 onderdelen sent the replacement, an entire shaft with both Lobros, one was rust welded to the shaft but is in better condition than the Lobro above the other was fine.

Thanks gents, just a shame the answer is no.

Nick, is the Metro/100 shaft splined the same at both ends? Cheers, J.

Noooooooooooooo......... Dan, no. Don't go putting ideas into my head. Spitfire first, Spitfire first ....... FIRST.
