I have done some preliminary drawings. The way I did them was to draw a circle with a diameter matching the maximum allowable amount and worked backwards.

This has resulted in as you have...

The finished OD will be without magnets. Because I'm wrapping it in Carbon Fiber I have allowed 5mm for the magnets + CF (magnets are 3.2mm high).

So if the desired overall OD is 108mm, the OD of...

Sorry for the incorrect terminology. Learn something new every day.

If the outer tube was thick enough he could remove some of the steel from the inner side?

Tonight after work/training I will...

Lol and there it is! I di'nt realise it wasn't automatic. I feel a bit silly...

Anyway the magnets are flat blocks. Due to the way motors are designed I need to use 6 to create one pole- hence...

Also I've tried replying to a PM stix012 sent me. After I hit send I would think the message would show up in my sent box. But it's not. So if you're not receiving them what the? But if you got 3...

OK I've sat down and done the numbers on the flat surfaces required to be machined on the outside of the main tube.

The easiest solution (but not ideal) I came up with was a flat surface 19mm wide...

If that's the easiest way to go about it then I'm all for it.

The only problem might be that the claw is a very tight fit at the moment (inside the stator) and once you machine that down and take...

I have an offer from someone in Brisbane to help me so I'll see what he can do. I will however post everything here just in case it falls through/for people who are interested.

I should stop...

n the interest of making this a bit better I'll actually sit down and draw some semi-decent pictures tonight.

Your comment on the rotor warping with the application of heat is something I never...

Hey no worries. If no one else replies I'll be in touch :2tsup:

Just to add some detail - the actual wall thickness is up for discussion. The total OD of the tube is the important part (so it fits...

Hi all,

I hope this is not inappropriate to post here ( I read the stickies about posting rules and it’s not mentioned…I hope) so here goes…

I need a custom piece of metal made up for me. I...

1500mm is a bit shorter than I was hoping for...I might wing it and go for 2000mm and if they sag i'll put some floating posts in.

Yeha I think some twisting may only occur if I don't get the footing right, but if it does I cna easily fix it like you have suggested. The capping is looking like it may go on anyway at this stage.

Hey thanks for the link - it's given me a few good ideas that I'm defintely going to take on board.

Not sure about capping yet - I'll ahve to see how it goes without it first because my...

Well the slats by default are 100mmx15mm, but I feel that they are too wide for the look required so I'm going to probably trim about 10mm off them to bring them down to 90mmx15mm. A bit of wasted...

Hi all,

First post so please go easy on me…sorry if this in the wrong part of the forum, please move it if it is!

I wrote a bit of a missive explaining my exact story but bugger it no one...
