    Thanks folks, really appreciate the help.
    My bed is 15x13 inches
    I worked out with Aspire that a 6x7 inch pocket, .75 inches deep will take almost 10 hours with a 1/8 spindle... That's quite long!

    There's a spindle on eBay that has a 1/2 inch collet (12mm) for about $70 delivered. Not sure what the quality would be like?

    It says engraver but I think it's ok for milling...

    Any other suggestions of larger sized spindles?

    Hardwood.
    16 inches per minute (machine max)
    1/8in pass depth
    Step over of 40%

    I increased if there to 90% step over and 1/4 pass depth and dropped it to about 5 hours

    Ok well the Low feed is the killer but even then with your 1/8 DOC and 16" feed & 40%STO it still comes out at 6hr 7mins in SolidCam and thats with Spiral down Entry. 5hrs 27min with 45%STO.

    With 90%STO 2hrs 48min.

    So back to to the spindle then about the best value for money IMO is the Chinese WC spindles, the smaller 1.5Kw would do nicely on a little machine and take cutters upto 7mm.
    They have relatively low run out and high duty cycle so can run continuously unlike most cheap air cooled spindles that often have Low duty cycles so will need to be turned off and rested after just an hour or so's continuous running.!! . . . To get anything to even compete you'll be spending lot more money.!!
