    Your pic is a little small, but it looks like a bridgeport with a J head, and an M head. Also has a riser under the ram.

    I have both heads on mine.

    Here is a shot - keep in mind that the motor...

    Thanks guys.



    I just figured the travel I needed and marked the extrusion all around. I made the 1st cut on one of the sides - thru down to the glass. Then I made another cut beside the 1st...

  8. Some Bridgeport DRO scale mounting pictures for your review

    Finally getting around to putting a DRO on my Bridgeport. Wet with a Chinese import. Scales shipped from USA, but the DRO is stated to ship on the 10th(Monday) I home the shit hitting the fan in...

    Motor tag is the FLA amp rating of the motor - full load amp.

    Running the motor with the belt off, you should not get close to that number for amp draw. I would say 50-60% max.

    You mention VFD...

    Thanks Bob, certainly is a rabbit hole I'm in.

    I understand about the thread title, but wasn't keen on how strict.

    Looks like I might have to settle for a TCMT, as the TNMT seems to be pretty hard to find.

    And the 1.5 size is even more rare, I think. But perhaps the 1.8 (9mm) would fit? I know the tcmt 21.51...

    The sides of the pocket do look square. The leading angle is achieved by the orientation of the flats on the main part of the bar. So you are right, I would probably be better served with a "N"...

    I think I have them all figured out except my small boring bar.

    It's a trigon with 8mm sides, but the thickness is 2.61mm or .102. That seems to make it a WCMT 4" " Blank.

    But that size...

    Thanks for that link. That's one of the ones I looked over. But now, giving it a 2nd look, it makes more sense that it did initially.

    I just might pick up that book - looks great. Lots better...

    Just a home hobbyist looking for carbides.

    I realize this thread is rather old, but I have the same question - Anyone familiar with ZS Instruments LCD DRO kits?

    Priced similar to the DRO Pros but have optical rather than magnetic scales.

    I just did a calculation of the 5/8" bit - at 750 rpm, that is 122 fpm at the cutter head. Correct"

    So, that does NOT factor in the travel speed. How do you factor in the travel speed? Just...

    Forgive my newbie questions. :lol:
    So, is the 50 fpm a good baseline for cutter head speed when using HSS? What about carbide? Is your 100 fpm just cutter head speed, or a combination of that and...
