damn the file attachement aint working.. anyone want to tell me how to attach jpeg files?

[kong]

Should work ok unless it is a big file?

[balsaman]

Don't forget to click "upload" after browsing for the file.

Is that mill a scratch build or did you start with something?

I started with a very used Ruttland round column bench top mill. Motomitch's square column conversion inspired me to do the same. The one thing I'm doing alot different is using a Air cyclinder as a counter balance insted of a large weight.

I tried to upload the jpeg file (converted from solidworks) the same way I did the initial photos and it dosen't seem to work.

I am giving it another go so if there is a picture then.....

here is some more progress on the very expensive not enough time in the day hobby project! The first is a close up of the spindle assembly and the second shows the spindle assemble with a spindle motor mount.. which i should have bolted up by tomorow But I still haven't got the pullys (do to lack of brainpower in ordering).

[miljnor]

wow those realy shrunk quite abit I will post them again with a little biger picture!

[miljnor]

here are the bigger pictures TIR was Much less than .0005 (Didn't have a .0001 gauge handy )

Is that the spindle assembly from the Ruttland mill??

[miljnor]

the actual spindle is from the ruttland. I have just removed all of the casting and the lame quill down feed and re-used the spindle and the housing for the spindle. I have replaced the bearings with high quality Nipponees bearings. and use Kluber highspeed grease (the best on the plant @115.00 tube, I got it free ).

With this bearing grease combo i got very smooth action and have no perceptible deflection and in the tenths runout. (didn't have a .0001 gauge handy but will recheck soon).

The onlything I have to still do to the spindle assem. is make a front grease seal as the original is either non existant or missing. I plan to run flood coolant so this is a must!
