Controller circuit for Hilden Brandt motor needed..

Hi Larry,
Well I have a lathe and mill.
So that is about all you ever really need when doing these things.
And such precision is not all that special machining wise, for example when machining an axle to match a bearing I normally machine it 0.02mm too big so that a heated bearing will just fit. And so these precisions are regular use.
0.07mm is about as thick as a sheet of paper. And needed when dealing with these systems.

Regards,
Steven

Thanks Steven. But, I'm more interested in how much that accurate of a lathe and mill would cost. I don't have either, but have earlier training. Would the large neos cost more than the lathe and mill or visa versa?

Thanks,
Larry

Thanks Jack,

And Hi Larry,
My magnets are only going to be 20x20mm each.
Jacks machine is gigantic and one needs very serious machinery to work on these sizes. And also you would need a ship load of laminated steel plates. The magnets would be the least concern since that is 'only' a money issue.

Well I could give you some indications what good machines cost. I for one don't use these flimsy harborfreight stuff like the 'mini lathe' or 'mini mill' But I use industrial machinery BUT second (or more) hand. These machines are often still very good and indestructible and would probably outlive you with these 'simple' projects. And since they are second hand they are affordable. Plus these industrial machine have the capability to do relatively large workpieces. especially on a mill that is more then handy, well not that mine is that big and such.
Here is my tools:

The lathe is a Ai Hembrug dr1 - Cost 850euro
Info http://www.lathes.co.uk/hembrug/
The mill is a Van Norman - Cost 500euro
Both are probably from the 1960's

Depends on what project you do, but I use these machines almost daily and so I money well spend.

Steven

Thanks Steven, I'll check them out.
