Kev,

I came to the same conclusion as you, that's why I am making one which is not as difficult as you may think if you have access to a lathe to do the mods to the ER16 milling chuck.

My spindle will consist of 2 angular contact bearings at the top to take out the end float and 2 bearings at the bottom to take the side loads, all housed in a steel housing which will be mounted with a couple of 20mm aluminium plates top and bottom.

Your housing could be made to your own design using whatever size bearings you think will be suitable for your machine but what I have should suit what you are after. If you want I could do some drawings of what I have to give you a starting point.

If there are parts that you need making that you can't do yourself then Johns your man, just speak to him nicely, take a couple of packs of hobnobs round and don't take the piss by 'borrowing' too much stuff off of him.....
