Sounds like you have the expensive parts already, if you have time to put into it I would say go for it as the interface you would need to make up would give a...
Hi all, I am starting to lay out a mini-mill retrofit and am thinking about using a fixed screw and a rotating ball nut. Anyone have plans ? ideas ? warnings ?...
Dave, Take a look at Hoss's mini-mill retrofit. I have plans from Ron Steele and they also show what you are looking for. Once I find a nice affordable...
McMaster seems to have about as good a price on ball screw as you are going to get new. they also have round and regtangular nuts. the round cost quite a bit...
Hello, I wonder if it is possible to built with hobby machines a lathe air spindle or a fluid spindle for a lathe. I am interested in this because of the very...
... See also: http://www.pic-design.com/ I think they might be significantly cheaper for the nuts at least. Their on-line catalog can be a little hard to...
John, I don't think you can get a Rutex at this point. The analog drive is a good option, maybe expensive if not surplus. You will also need to find a Rutex...
Please excuse my ignorance but....... I just ordered a ball screw and nut from McMaster/Carr and it appears that they are shipping it in two seperate...
hi- it's easy. the ballnut comes with a tube through it. you just screw the ballscrew into the nut while holding the tube. there should be instructions there....
Its easy. Put the cardboard tube against the end of the ballscrew. Scotch tape them together (3m magic tape etc). THEN roll the nut on it. Cant miss, canīt...
There will probably be a sleeve in the ball nut part that you will need to keep in place as you thread the ball nut onto the screw portion. At least that is...

This subject was discussed at length on the "Quorn universal cutter and grinder" group. Nobody got it to work! Matthew Cristi <wtherapy@...> wrote:...
Dave, They were out of the one I wanted. Will have to look again shortly to see if they are in stock. Ron's design calls for a fairly coarse screw that will...
Awe, that sounds too easy! No counter clockwise electronic spanners required? You guys could have had some fun with that question. Thanks David! Now...

... There was an article in home shop machinist several years ago. Some fairly crude procedures were used, and the author said it works. I think a good home...
... Yes, you can use the Pico Systems Universal Steper Controller and the Gecko Servo Interface with the Gecko drives. The Gecko interface powers the...
... This would be fine to do with a collet directly in the spindle, but would be a very bad idea with the typical manual machine 6" lathe chuck! As in...
Hi Jon, my lathe is converted to CNC and I will attach linear encoders with 1 micron steps. I presume this is fairly precise ( although I know at 1 micron...

It was more for fun than for necesity. BTW, I found this http://home.insightbb.com/~joevicar3/Air_Spindle_Plans.htm - has anyone tried/ built this? My lathe...
