Mills

I'm planning on getting one of the HF Micro Mills and was wondering who on here has experience with them. (or just mills in general)

I think I have it pretty much figured out except for how to hold the bit in place and clamping my work to the table.

To hold on the bit I've heard that its better to use a collet rather than a chuck.? Say if I was only using 3/8 in bits this would be all I need?


And on the clamping part I'm completely clueless. Any help there would be gladly appreciated.

Is there anything else that I would absolutely need to have?

And wheres the best places to buy Aluminum sheet? I bought a piece off of ebay a while ago, but since then it seems the selection has gone way down.

Thanks
