It appears to be cam operated between the bed rails? Can you have Benny take a few more pictures of the mechanism that drives the saddle back and forth please. Thanks, Rich

Benny is me, I think, :nuts: and no I don’t make bushings. I had noticed a topic about how to cut the internal oil grooves in another forum and it caught my interest. While visiting family in Fort Worth during the Thanksgiving holidays I got to see the old machine in the video. It belongs to a friend that I worked with about 25 years ago. He has a machine shop that does all kinds of maintenance type machine work. He has an interesting collection of machines and adopted this machine and gave it a home among his planer, shaper, gear cutter (both shaper & hob), plus the usual manual and CNC machine shop tools. The original post is here: http://www.hobby-machinist.com/show...eve-bearings-in-the-old-days?highlight=groove
Not sure how the carriage is moved. Gary, the owner, did mention that it could be adjusted to cut more than just the figure 8 grooves.
I can't take more pictures right now as I am back in Tennessee. I plan on being back in Fort Worth around Christmas and will ask Gary if I can come over and dig up more information on how it works. I would kind of like to know myself. Gary did mention that the machine was designed so that the tool bar on the carriage held a single point tool like a shaper but that he used a die grinder to cut the gooves since it is quicker.

yes, there are some designs that need a valley for grease or oil. as a matter of fact a type of hamburger patty making machine i work on frequently has a bushing that has 8 criss crossing grooves on the i.d. that were formed then impregnated with carbon,then reamed to dimension. they work very well in moderate stress conditions where the operators forget to grease up. the carbon acts as a lubricant , and the shafts seem to wear nicely even after 100,000 cycles.
