VN Slotter Head

[BROCKWOOD]

Almost ready for paint is my newest acquisition - a Van Norman Slotter. Best I can tell there are 2 sizes that were offered. The difference being in whether it was made to receive 1/2" or 5/8" slotting tools. Having said that, a prospective buyer still needs to be aware of the mount portion & whether it will fit your mill or not. My slotter is the larger size - but with a mount for a no22 (same as my hi speed subhead). It came with an adaptor that fits it to the 24 & up sizes & a drive that fits a 1 - 1/4 tool holder. I found a 1 - 1/4 tool holder for a good price. Here is the drive & holder joined.



Well, the shoulder is too thick for the adaptor. Here is the adaptor all cleaned up.
Mill side.



Attachment side.



I'm just about ready for paint. Since I'm on night shift in a few hours, I'll leave these pics for now.

Paint! Well, humble beginnings. Still lots left to do to get it ready.




I coated all the bare surfaces in axle grease & fitted the ram in the slide. Before connecting the ram to the cam or even adding the gib adjustment screws, I worked the ram back & forth. Somehow it is tighter with hard spots. Getting close though.

The last pic in the previous post shows where 4 gib adjusters go + 2 gib locator pins. Those pins were the cause of my tightness as they were in too far. All adjusted now & working!







The hole in the mount should be at the top. There is a brass sleeve in it. I'll need to get a replacement oiler for it. What are the ones with the spring loaded caps called?

Mounted the adaptor to the mill spindle (it's upside down). Just needing measurements for now anyway. I have to make a 7/16 x 14 grub screw as the 4th mount. Finding the right NMTB 50 x 1 1/4 tool holder for cheap could be a challenge as the shoulder has to be less than 5/8 thick.

I've seen them called "ball oilers" or "ball detent oilers" or "ball valve oilers". McMaster-Carr carries them: https://www.mcmaster.com/#ball-oilers/=f8f5ed72b0c149a8bfac848638c6d215jw9rl1w0

Yes Cal, this slotter does have a couple of intact 'ball oilers'; but, they are not brass. I don't like ball oilers, generally speaking. Perhaps it is because the Grizzly's, MCS etc don't know how to stock an oil can (dispenser?) that actually works. I now have a collection of old Eagles that do the job admirably! But, what I want in this vertical spot is an 'oil cup' with the spring loaded cover. Sorry, I didn't know how to ask. McMaster carries these too! Now to remove the broken brass sleeve (of the original oiler) & see what threads are there. I actually expected a press fit based on the thin wall section of the oiler remains.

I've noticed few of these from Van Norman for the smaller mills that have a bracket or cover mounted to the top. Mine has no provision for it. Would it be beneficial to add 1?
