My VFDs are controlled from both the VN factory pendant, which can be placed anywhere, as well as the side buttons. I'm running two, one for the spindle and another for the feed motor. They live in a...

Is there no access plate on the VN 38 to open up the cutterhead? There's a large access plate on the 1R3, more than enough to measure the ring gear without taking off the head.

There is a...

Yes, and on the 1R series you don't even drain the transmission as there's an oil seal on the output shaft to the cutterhead. You can work it off supported by wood blocks on the table. The spud the...

Using it as-is certainly isn't an attractive choice, but you stated your use is for hobby use, so I figured you can afford to "go easy" on the machine and/or have downtime if it eventually breaks. I...

Wow, that is awful. I'm really sorry to see such critical pieces in such poor condition, and I have to think you're right - if there isn't a ton of gear detritus in the housing, someone must have...

The lower end seal closest to the spindle nose is marked 'J-M' and '5355'. My upper seal was a bit crusty but seems to be marked 'J-M' and '5627 P0'

I added photos with these markings to my...

This thread starts with a discussion of spindle bearing grease and then moves on to me pulling the spindle and describing how things were cleaned up, gear lash checked, and a link to an album with...

Nice!! That's going to be a great machine - quill, bigger table, more X-Y travels, 3-axis powerfeeds with rapids :drool5:

Mike,

Sad to see you leave the ranks of 1R owners, and thanks again for the help you've given other VN owners. What is coming along to prompt you to give up both your VNs? Feel free to point me to...

Rich,

As far as I know, the 1R-3 series came only with NMTB 40 spindles (the 1RQ-3 spindle, which has to fit inside a quill, came with NMTB 30). I know you have mechanical aptitude as you had your...

Richard,

Not too late at all! I've been using the machine as-is for now (though not as much as I'd like between the holidays and some bitter cold), and hadn't yet decided what to do about this,...

Good thought - as you know you weren't measuring the runout of the spindle taper, but rather the runout of a system that includes the spindle, the toolholder or collet and the tool itself. Lots of...

Good advice from Paolo. Horses for courses:

-If you only need to work to loose tolerances (.01" or so - lining up bolt holes for example), spotting on the mill and drilling on the drill press is a...

I have a combination center/edge finder but it never occurred to me to use the center finder for anything but small holes (those too small to locate using the edge finder in each of the two axis of...

:o Of course, why didn't I think of those. Thanks!

I have the same question - with the gears not anchored to the shafts, there's no way I can think of to push the shaft fore and aft, nor a place to put a test indicator on, in order to measure the end...

As you mentioned, the spindle requires class 0 bearings (or better, but I'd say it's overkill as sub-thousandth tolerances are too much to expect of most any milling machine). Standard class 2...

I think you're making the right choice. At least, you can start with a fairly low commitment item: Pull the top of the transmission off - you will be able to really look at everything, be able to...

I know how you feel - I'm no machine restorer, either. I bought my machine having tested it under power and making cuts, so I figured it was good to go. That said, every single thing I've taken apart...

After running 10 minutes at 1530RPM:

You might say, "Huh? Ben promised to run it wide open at 2000RPM." Well, as described here, my belts are slipping and need replacement:...

Attached are the results - I'd say that in terms of air entrainment/foaming, the oil performed admirably.

Before running:

After running for 5 minutes at ~400RPM to warm up a bit:...

Again with the caveat that my limited knowledge is built mostly on what I've read from other people's experiences and recommendations, I have to say I've never seen gear oil recommended (the opposite...

I don't mean to be difficult, because I certainly have no special knowledge of any lubrication subject. All I know is this is what I bought, and it has everything you mentioned:

Advance Auto Parts...

The serial number on mine is 6103-363, which seems to indicate it was built in late 1963. Pretty early in the run - perhaps the 93rd of 452 machines built.

Very interesting! I wonder why they changed the lubrication spec from (effectively) ISO 32 to 68. I also see something that looks like "...LIFETIME GREASE" for the spindle bearings, whereas my...
