(sorry to post off topic)

i am really wanting to join in on topics such as this but you people are so far beyond me its not funny... could anyone recomend a way for a newby to these things some way to "catch up" a good conprehendable book to bring me up to speed? i am afraid i am to far behind to catch up this way but i will attempt anyhow. thanks

Hi Danny,

First off all I think everyone is welcome to join. I suggest if you haven't already done so to read this topic from beginning to end and have a good look at all the pictures and ecplanations given. That way you might get up to standards really quick. If things are still unclear about what we're trying to achieve just ask. The who;e idea is to make this a common project...

Let me mention also about the HD which I prefer before the CD 'cause it's sturdier. My HD has aluminum casting which is very hard to do anything with and is surrounding the disc - disc is simehow dipped in this aluminum shell. Anybody with exerience with these HD's? Probably we should agree on a certain diameter of the HD disc as well.

Should be able to get the whole engine and platters out of the casing. I think just go for the 3.5 inch HD. Thats a standard size. Everyone agreed on that?

Hey guys, I think we may be putting the wagon in front of the horses...

We may need to find the MAGNETS (size and shape) we need first, THEN design the sizes accordingly. I am looking now.

Also, we may want to design the first out of soft wood, even balsa...so that it can be worked easily, and parts can even be cut without expensive tools (even hand tools)...when we get a design that works (or close) we can progress to a metal design.

Hi Jay,

You could be right here. Once we've created one stator segment we know how big it is and we can work out the diameter of the circle they sit along (in case of 16 stator segments: (16 * width of one segment / Pi Right??) From there we can also derive the size of the rotor (little bit smaller then the inner circle of the stator).
I'm not sure about the balsa wood. Isn't it better to start with a readily available U frame (aluminium) ?

Quotedutchy1966: I'm not sure about the balsa wood. Isn't it better to start with a readily available U frame (aluminium) ?

? That would be pretty simple to work with also... the only thing is that we may have to purchase an entire stock length, which is the case around here (unless you have a metal shop willing to sell cut-length). The metal shops close to me only carry a small line of aluminum, usually square tubing and rod, but I will look for some I-beam and channel today...

EDIT:

These magnets are interesting, but may be too small of diameter (43mm OD)...but it is possible...Part # M5005
