Here is the cross slide set-up; the Bronze handwheel was todays effort; the alumi support was also made today (tool post is beside the cross slide)
The circle you can see is the referance locator for the compound slide; it keeps it on center as you swing the compound through the arc; an 8mm screw locks the compound
Looking right down the cross slides center; the small setscrew deep down is the adjustment for backlash; there is a small teflon button under the screw; it presses the leadscrew into the nut to reduce the backlash; the other 2 cap head screws hold the nut under for the leadscrew
Compound slide being attached; the 6mm allen key is in the locking 8mm caphead
Here is a bottom shot of the compound; the locating ring can be seen; the 2 small holes in the alumi handle extention are for gaining access to the locking 6x32 setscrews that lock the handwheel and the leadscrew adjuster
The compound on the cross slide; the allen key has locked the compound at an angle to show how tapers can be cut; the bronze insert in the middle is the nut for the 1/4"x20 leadscrew (0.05"/rev)
The final normal setting for the compound slide; the access hole for the taper setting is now closed as it's quite far ahead of this position; also helps to keep crap out of the allen head; tool post is on; the round guide bars for the main way are visible too; these are Thompson shafting; held with 4mm capheads into a CNC machined 90dgr each side of the main bed; these are accurate to within 0.001
Shot of the collet set-up; also in the shot is the main leadscrew bearing (just under the collet chuck) this will support the 7/16"x20 (0.05/rev) leadscrew
The collet chuck still need 2 holes drilled into it for tightening; the adjusters for the main carrage can be seen too with locking nuts; these again like the leadscrews have teflon buttons to help maintain accuracy; the cross slide has smaller set screws for the same reason (2 small holes just above the main section of the carrage)
Drive end of the spindle; the 1.125 dia is threaded ready to hold the 8 step pulley; the main bearing can be seen; another is right behind the collet chuck; the spindle can take 0.650" through; the run out is 0.0004" at this time; once the drive is complete I'll grind it totally true with a pencil grinder in the tool post
I'm also going to add chinese scales and make the ShumaTech DRO; there will be a tail stock added and a 90dgr block to make the compound into a vertical slide; the tool post will be removed and a small vice added to hold small parts
Top speed wil be over 12,000 and lowest speed will be just over 1400 with 8 steps
One day (after my NC mill) I'll CNC it
I should add; the project was designed in SurfCam 2001; the machines used to make the parts were a Supermax 56 and a Fanuc wire
I don't work at that place anymore (projects like this are not allowed; and I had to hide it all the time); my new place the boss says "hey just build whatever you want" (in my time) The Mill project is coming nicely in SurfCam 2002 and I'll post a photo of the shaded surfaces soon
