Now that I have good drawings, piece of cake, although I did grab some 
bad material and spent quite a bit of time chiseling the packed up tool 
out, and used a good cup of ButterCutt keeping it clean.  So thats made 
and partially assembled.

Being out in the hinterlands of WV, nobody stocks metric bolts deep 
enough to keep me in the right bolts. so I now have about 6 to bite off 
8 to 10mm of, and grind away the cut end until it fits the threads 
again. By then my back said it was quitting time, so thats tomorrows 
job.

Then I should have mounted it about 2mm left as I don't have room to put 
a grease fitting in the nut unless its a straight 1/4-28, but I don't 
think even that will allow a gun nozzle's access.

And everytime I look up lube recommendations I get a different story.  
This writer for so-and-so wants 10w non-detergent, the next guy wants a 
high grade 10w-40 detergent, and the third guy wants white lithium 
grease.

Cheap, rolled C7 grade screw, what would you folks put in it at about one 
gun pump a month?

Thanks everybody.

Cheers, Gene Heskett

Mainly because I don't have a boring head, even fly cutter style.  Its on 
my list of tools to acquire though.  Once you get above the 1/4" mark in 
carbide mills, it rapidly escalates out of my pay grade. But with good 
drawings, I can make this pad I need.  It was, maybe still is, a lack of 
good drawings that brought this subject up.

Thanks Andy.

Why would you buy a mount when you have a mill? surely one that you
make yourself will fit with fewer compromises?

Not a lot Roland, that several page long chart is for the nuts 
themselves. Nut mounts, other than what they should do well in terms of 
alignment with the nut to screw axis, aren't mentioned anyplace in that 
nominally 206 page pdf.

Google for "ball nut mount footprints", and this one fits the screw I 
have perfectly, is the "hip roofed" style for a 2505 screw. There are 
also square topped varieties.

Go here:

scroll to the bottom of the page. The lower left image is the style of 
nut mount I have. Clicking on that image, which I didn't know you could 
do, links eventually to:


Which agrees 100% with the DSG charts for a 2505.  So now I have 2 
different sources for a footprint drawing whose data match.  It looks 
like I have some measurements to double check once the pills and coffee 
kick in. Thats sort of an osmosis like process. :)

Thanks Roland. I appreciate the effort to help.
