My 4th axis build

[Thor]

Started working on my rotary axis for my table today. Lots of machining and welding to do now.

Don't forget pictures when your done, we like pictures

[WyoGreen]

Quite a pile of parts there, I'll assume all cut by your plasma. Make sure to post lots of pictures of your progress, as there is always interest in these rotary builds.

Good Luck, Steve

bump... subscribed for generous pics and hopefully plan files. ;D

[Thor]

I doubt too many would want plan files, lots of machining and this is for a 12" chuck.

[Thor]

Got a bit of welding done on the rotary frame as well as the chuck backplate. Need to order some tubing Monday for the spindle. Now I can start machining the frame for the bearing hole and mounting holes for the bearing flanges etc.

[Gamelord]

Looking pretty awesome there buddy.

[Thor]

Got most of the machining done on the main frame, still have to punch the holes for the jackshaft but first have to figure out where that will be more exactly.

Should be able to machine up the bearing flanges sometime tomorrow.

[Thor]

Got the bearing flanges machined. Still have to tap and countersink them for flat head screws yet then they will be done. Then have to design up a timing belt pulley and whenever the tube for the spindle gets here weld that to the chuck backplate and start machining it up.

Looks like it's going really good so far. I'd definitely be interested in the files as I'm looking to attempt the same thing shortly. I was planning to use an 8" chuck but I could always buy a 12" or scale this down. What motor/encoder are you using?

[Thor]

It will be using a 750 watt ac servo motor from DMM tech.

[Thor]

Got the spindle tube welded to the back plate and machined to fit the chuck. Decided to machine the tube while attached to the chuck so as to be sure everything is perfect alignment. Hopefully tomorrow I can get a bunch of turning done for the bearing fits.

For size ref the lathe chuck is 16"

[Thor]

Got the spindle tube all machined today. Just have to make a nut for it now.




And the obligatory trial fit. The bearing alignment in the frame isn't quite perfect but the way the flanges hold it, when the frame is in the mill for putting the jack shaft holes in I'll bump the hole ever so slightly in the frame.

Also can finally add another support gusset to the tables mount arms for the rotary now that I know where bolts are placed etc, should take the last of the wiggle out of that arm with a brace down to the tube support beam.

Nice old Monarch...parts look good.

[t-tracks]

is there any more work done on this? I am going to be building a tube cutter as well and this is good work.

[Thor]

Sadly no, been too busy. I did get a 3d printer and have been thinking about using some carbon fiber filled stuff to print a timing belt pulley for behind the chuck.
