    The mill has a 2HP motor.

    should drive a 2.5” facemill I think

    Good condition Clarkson S-type with 40INT 5/8BSW turned up this morning. Only 3 collets and was missing the spanner but it’s in its box which is a bonus. The collets are metric so I now have a full set of imperial and metric collets, I already had a 16mm metric collet spare.

    burnt up the only good sharp endmill I have though on this cast steady. Need to order a bunch of cutters.

    Really I should get a tool & cutter grinder!

    Yep I’m headed that way. Insert end mills will work out cheaper in the long run I’m sure. Still, nice to have HSS tools for softer metals.

    This is as far as I got before we were blunt. Conventional milling too, not climbing. 25thou of cut. Probably needed a deep cut if it is induction hardened.

    Wicked thanks, I just chuck random stuff on there, mostly new tools! Haven’t used the collet blocks yet but I’m quite happy with them for the money.
    First job for the square block will be to reduce the size of a nice chuck key I have that doesn’t fit any of my chucks. Second job will be a hex chuck key for the 4 jaw so I don’t have to use an Allen key.

    Were you cutting that dry or with coolant. Feeds and speeds are very critical with hss tools on mills

    Dry.

    That’s exactly what it was mate, I was at 888rpm and 0.024ipr which I was cutting aluminium at the other day. Looking in the clarkson manual they recommend 385RPM and 3-1/8 inches per minute. I was pushing the cutter too hard.

    Every day is a school day.

    Looking on my mill, the speed closest is 416RPM and I do have a feed rate that will get me close, 0.008” per rev, which would be 3.25” per minute of travel. Little bit fast but probably wouldn’t have burnt the tip up.

    Cast iron should be machined dry.
