  1. Nice machine! I wish my VN12 had a quill!

    Thank you. This is the idea I will try to implement.

    I am going to make a simple clamp to hold a scale on the table edge, as you describe.
    BTW,did Hauser supply tape for the fingers with the machine? I am told it is the best way to keep track of...
  4. Ya think? Have you ever lost count of anything?...

    Ya think? Have you ever lost count of anything? Never been interrupted?
    You think those guys who wrote the book "Accurate Tool Work" needed tape on their fingers? They seemed quite enamored of a...

    1910 give or take- I don't have the book in front of me, but they were speaking of gauge blocks like they had just pulled the sword from the stone.
  6. I pulled "Accurate Machine Work" off the shelf...

    I pulled "Accurate Machine Work" off the shelf and did some remedial reading,as johnoder put it.
    They talk a lot about the use of vernier scales and micrometer stops to retain and return to...

    I am not concerned with holding .0001", or even .001"- I am concerned about being .200 off, because of having lost count of turns.

    I did make a stop block for the table travel, but the lead...
  8. retaining position locations on mill without DRO- vernier scales, stops, ?

    Seems most mills these days have a DRO. Let's talk about the old days:)

    When a series of features are called out, and referenced by location to a zero point, either by absolute or incremental, it...
  9. I will try that.

    I will try that.

    I got a standard ER16 to 1/2" straight shank toolholder, not a VN to ER.

    It is being used in a 1/2" VN collet.
  11. The Maritool ER16 collet holder came in today,...

    The Maritool ER16 collet holder came in today, and on the old VN it is running .0015 out on the drill I have in it. Very much better than any chuck I have, and at least three inches of space saved! ...

    Cool tool! I had never seen one. The platens run vertical behind the belt? Post up a few pic's if you have the inclination, when you are doing the repair. Curious as to how the belt tracking is done...

    Your mascot called me on the phone. Needs a counseling referral. :)

    BTW, what is a Zimmerman profile sander?

    Fair enough:)
    Another way to approach this is to glue it up as you suggest, then use a long radius scarf cut along the axis of the break on the inside, from almost through to feather edge a few...

    Thank you.
    I was surprised at the Hardinge quote, as they must have programs for the 5V and the ER , and they build an R8 to er arbor also- so I was thinking the development time would be minimal-...

    The customer is not always right. My response would be to simply say "No" to a repair. Buy a replacement, or laminate up a new piece.
    What do they gain by a very expensive, marginal, repair?

    Cal, where would I get small quantities?

    My only experience with the 4140 steels is in the annealed state, and they were very sticky and hard to get a good finish on . (for me as an novice). I...

    VN 5c/ Hardinge 5V.
    Now there is an interesting idea! I was figuring on clamping the ER16 toolholder in a 1/2" collet or endmill holder. Never thought of silver soldering it in. I could also just...

    I am liking the freeze spray idea to shrink the arbor.

    OK- how long have we been using chucks and arbors- and Jacobs says you STILL have to drill a hole in the chuck? And STILL the tapers do not...

    Cal, on the MT collet to VN5c- the collets would need a separate drawbar, yes? So the MT collet drawbar would either go through the hollow VN drawbar, opr replace it entirely, or the MT collets would...

    You understand correctly.
    Inertia- the hammer blow drives the chuck away from the arbor. The mass of the arbor wants to stay where it is. The wood block is just to cushion the chuck so you don't...

    I had to switch around some tapers and took a short piece of pipe that would just slide over the Morse and Jacobs taper and sit on the chuck body. Unscrewed the jaws till they retracted, put the face...
  24. Thoughts on tooling the Van Norman 12 for drilling.

    The VN 12 has three main limitations as a drilling machine- no quill, the limited space between the spindle and table, and the lack of VN 5c toolholders. When used as a vertical milling machine, this...

    Make end mill holder- bore or ream?

    I want to make a endmill holder-7/16". This is for an old machine, so holding tenths is not necessary. I can make the arbor ok, but have a question on the hole- should I bore the hole to final...
