I recently read somewhere about a company who will machine new parts based on plans that you submit to them and then send those parts to you. Unfortunately, I can’t recall where I found the original article (I think it may have been here but aren’t sure) and am asking if anyone recalls seeing such a firm mentioned here and might know their web address.
 
There was a company referred to on “The Mighty Garage” YouTube channel, where silencer brackets and some other stuff was made.



Called SendCutSend.
 
I believe that @ Time Warp (long time member in here) does this for members, when work / life permits.

Worth a DM…

Greg,
Would they skim the rotor for my charging system?
Thanks,
Mike

Don't think so. Using their free software, you design a part and submit it. They make the part in whatever quantity you specify and send them to you.

Any fabricator equipped with a lathe or a grinder should be able to help you. There are also privateers offering such wervices. Ask around with car and motorcycle clubs in your area.

By skimming do you mean reduce diameter ? If so then anyone competent with a lathe should be able to take care of that - unless there is something I don’t understand about dealing with rotors - magnets , etc .

I had mine skimmed by a reliable local machine shop. Turned out perfect.

how much did you skim off? 😏 The reason my bike was sold to me was because the rotor fouled the stator, overheated it and caused it to fail. The previous owner didn't want to deal with it and sold it to me when I was 19 years old. I got the rotor/ stator distance worked out, but if a little extra space was possible, it certainly would preclude a re-occurrence...

I had the mine machined down by 6 thou. I wasn’t able to get the recommended clearance with the rotor as delivered.

I've had many parts made by Sendcutsend.com and Xometry.com. Again, send them a vector file drawing, they cut/make the parts, and you choose the finishing services you require. You can end up with a fully finished part. I would recommend getting things at least de-burred and tumbled. I generally use them for laser/water jet cutting. I was considering buying a water jet machine a couple years ago, but these services are so cheap, there's no way it would be worth owning my own machine. The last order I placed was 6 separate parts in a dozen quantity each, and the order was in the mail in 3 days. Incredible.

Any local machine shop should be able to turn a rotor, but if you can't find someone, I certainly can. I've done it several times with good results. DM me if you need it.
 
For those turning rotors please be sure to use a ceramic insert and take very light cuts. Rubbing steel on magnets can demagnetize them. Also realize that it is usually not the rotor that is a problem but is often the insulation on the inside of the stator and/or the spacers behind the stator being slightly different lengths.

The magnets are underneath laminated caps so it shouldn't be possible for the tool to come into contact with the magnets.

Post in thread 'Lucas Alternator rotors'

I wanted to see what was inside these rotors so I sacrificed an old rotor (part number 54212006). I melted all of the zinc away and this is what I found. It appears as though the hub is made from a hexagon bar stock and the magnets are simply attached to the hub. Then there are laminated 'caps' that are placed on top of each magnet. Each of the laminated caps are held together with one rivet. You can see that the laminated caps are made in such a way that they are held in position once the zinc casting is poured. Even though the magnets were weak this rotor appeared to be in good shape...

The caps extend the magnets. A HSS cutter will become magnetized and will affect the magnets. As usual, I tried to simplify. Turning with HSS can reduce the magnetism. Turning with ceramic cannot.
 
When I was living in Melbourne, the most accurate machining was done by the guys who made dies for plastics injection moulding. I now live in a regional town and the best work is done by the guy who reconditions car engines. There are two other engineering shops - only one of those is worthwhile. After a while, you get used to farming work out to machine shops. I live in Benalla, Victoria - in Euroa which is about 30 kilometres away, there is a machine shop which had quality certification during WW2 - they can do anything - even gear-hobbing. The guy who set it up died decades ago, and his son died recently. He raced motorcycles, and was running the business. I know a guy who still works there - so the business is surviving. For jobbing work, Melbourne would be pretty hopeless these days.
