Looking at a Lincoln R3R-300 welder & the owner was telling me he was downsizing & as I was looking over things I found a very nice J Hrad Bridgeport with something I've never seen. Factory "Bridgeport Optical Measuring System". They're on the X & Y axis & have flip up covers that say Bridgeport. I called Bridgeport,no help. I called Matako & he'd never seen or heard of them he found the following picture. Just wonder if anyone can tell me the aprox age & if anyone has used them. Needless to say what's one more welder & mill. Thanks! Sorry it's upside down & they look much cooler in real life.:D http://i1119.photobucket.com/albums/k631/fly-lo/th_1342212566.jpg (http://s1119.photobucket.com/albums/k631/fly-lo/?action=view&current=1342212566.jpg)

There you go, a bit more info.


Ive seen several of these systems on various Bports, but never in working order. I believe they are from the early 60s, but could be wrong. Neat, but I would prefer a trav-a-dial or DRO.

Thank You, I should have looked there. This one works & the mill is in really clean & tight shape. This was just a little frosting on the cake. Now the bottom has fallen out of the scap market machines should be free for the moving.:eek:

be preprepared for eye strain ..

I have one..came with it ..I took it off

1. it takes away a few inches of your travel ..mine has the old power feed ..the box prevents the table traveling all the way from right to left, power feed box used to hit it.
2. it does not have a zero facility .
3..one of the scales replaces the way wiper
4 hard to see....you have to have your face a few inches from it .not good could be dangerous.

sell the system on ebay ..with tonys pictures ..there is a sucker out there who will think WOW .

with the money buy a digital system

all the best..markj

Flylo I bought an Excello that came equipped with them, while it may say BP I think they were made by another company, perhaps French.........heres my original thread that likely covers most of what you've discovered.....
