Help with drill-Mill conversion

[BillTodd]

possibly 6mm and then it will be a springy drawbar

If it screws upwards it'll only be about 6" long

Those heatsinks are 425X300mm

I built an amplifier with a similar sized one :)

Bill, just re-read your first post and realised you suggested mounting the chuck from underneath then, sorry I didnt twig.

Anyway just ordered the angular contact bearings for the spindle and found a suitable ER collect chuck. But not sure wether to go for the ER32 on a morse 2 taper so i can use the collets on the big mill when I make it.

Any one know if will this be ok on that size taper? and In reallity will I need 20mm capacity for milling Ali?

Any one used the cheap chineese stuff? ER32 collet set is still £50 so not that cheap if its useless
Cheers
