Small world! I am the one who bought the head that used to belong to Ramsay1 (thank you again!!) around a year ago. I'd also corresponded with Brockwood on the VN Yahoogroup forum. My VN 1R3 has 3 bolt mount pattern on the machine and the head I bought from Ramsay1 has a 4 bolt mount flange. Meanwhile, Brockwood has a VN22 mill that has a 4 bolt mount pattern on the machine and his head has a three bolt mount flange. It's possible that the three bolt mount flange on Brockwood's head, if it might interchange with the 4 bolt head on my head that I bought from Ramsay1, might give both me and Brockwood both heads that would be "native fit" for our machines. I am hoping that maybe just the flanges can interchange, because there are other aspects of the head that I got from Ramsay1 that I prefer to keep. That'd also be a lot easier with shipping if we can just trade flanges. Brockwood and I are now exchanging details, although it may be a while before I can get out in my unheated VT shop to get the details from my head, because I am getting over some aggressive germs.
Yes a K&T vertical would make a good pattern, but I have no idea where I might find one in person to take measurements from, kind of a machine tool desert here and a-bouts. I have a few projects lined up ahead of this one but am trying to form a solid plan and gather the bits and pieces I'll need to pull it off. Now if I can only find/scrounge the skills required to do the old gal proud. LOL.
Any idea what taper the head might have in it? the mill has a 40 taper, so the drawing of the drive adapter above will come in handy.
Also. while I have ya'all, I have some 3/4" steel plate here, but my thought is that it might not be thick enough by the time I clean it up and square it, I'm hoping to scrounge some 1" or thicker......
Thanks again, Don.
Abom79 & James Kilroy have both shown installing & removing the stock vertical head from their K&Ts on YouTube. Might get some ideas from them.
Essentially, the head centers on the spindle & a bar on each side clamps it to the vertical ram. Similar to how Van Norman did it on their horizontal mill as seen below.
December kicked my ______ on schedule, between me being sick, things at work, helping my parents with winter/ holiday/ medical issues, etc...But I am starting to be able to come up for air. I hope to be able to remove and at least begin to measure the rear subsection of my VN head tomorrow (Sunday) evening.
If it turns out that Brockwood and I can swap the read portions of our heads, so that my head bolts up to my 1R3 with nothing in-between, and his bolts up to his machine with nothing in-between, then I will have as a "leftover" the adapter plate that Ramsay1 (who I bought my head from) had used to previously adapt the head onto his K&T- which means that the adapter would be available for 140mower (if the dimensions of his K&T are similar to the K&T Ramsay1 had the VN head on).
That would be nice if it works, but I have my doubts, as the 1A is a pretty small mill....... The column on mine is 10" to the widest part of the dovetail. Either way, if possible I'd appreciate it if you could take a picture of the adapter Ramsay1 made to see if the picture in my mind matches what's known to work.
Thanks, Don
I made that bracket for a K&T 2hl which has a 9 inch column....Ramsay 1
