Vertical Milling Device????

 

Some years ago there was a member of this group who built an add on device for accurate vertical positioning. I think it was known as a Unimat Vertical Positioning Device. I believe he sold a few copies.
Would anyone here be able to point me in the direction to a picture of this device?

Here are pics of such a modified Unimat that was on ebay sometime last year. I'm not certain if this is the same as the kit you're referring to but it looks quite well done and effective.

Thanks, Kevin!
This one is very similar to the one I was referring to, and very well done.
As most of my milling operations are carried out on the Unimat I could definitely definitely benefit from a more accurate means of location than what I currently use as well as a dedicated setup.

If you search the messages for "UPVLA" a bunch of messages discussing it come UP.?


Here's a review from Martin

And here is a photo album from John K when he developed the prototype.?

After looking through the album, I think this is the same modification the eBay listing had. If I remember correctly, that sold for ~$550.

These are very useful photos.? I am currently working on something similar , as per attached photo.? However, I machined an aluminum block to fit into the Unimat mount and am securing with screws.? Am I to assume that the screw is 1/4-20 and the support rod is 5/16?
Please note that this device is supported with a cut off Unimat bed.? When I did this previously, some here were crying and complaining what a sacrilege it was to cut up a Unimat.
