What keeps you from using your rotary axis?
I'm putting together some training material on wrapped rotary machining.
I'd like to hear from those of you who are curious about rotary axis, but haven't really done anything with it.
Do you have a rotary axis?
If not, why?
If you do have one, have done anything with it yet? (Mine sat under the CNC table for 2-3 years before I did anything with it)
If not, why?
If yes, what problems did you encounter?
What are the very basic questions you wish someone would address regarding rotary?

Nervous because I haven't the first idea how to begin.
I look forward to your instructions.

Re: What keeps you from using your rotary axis?
I don't personally have questions, as I understand how to use my rotary axis pretty well. My students get a puzzled look on their faces when I point to the rotary axis. It's the same confused look they had when I pointed to our many conventional lathes.
We do use it though. Often just as an indexing jig for parts that need work done on different sides a precise turn from each other. Very often to turn simple tapered legs for furniture projects. Simple cylindrical or elliptical legs or stretchers. I've caught students making baseball bats with it. I can't seem to get anyone interested in making anything more complicated though. "Mid century modern" is the youthful depth of their imaginations.

Re: What keeps you from using your rotary axis?
I have done a lot of rotary work. Several issues that always seems to cause caution and require a lot of thinking/designing:
1. Finding suitable materials for bowl type work. Warping while carving can be disastrous.
2. Finding the right balance between what to do on the lathe vs the CNC and in what sequence
3. When wrapping around an object there is no "beginning" and "end" in the traditional sense as it is a continuous circle. Creating a design in those cases is complex.
Looking forward to your lessons.

Re: What keeps you from using your rotary axis?
I've used it several times to make a few canes and then tried walking sticks which I find more fun. They turned out great. It's really nice to be able to do something like this and be able to either v-carve details into the cane/walking stick or to add in 3D models onto the cane.
I stopped because of the length versus support issue for the walking sticks. I have the Stinger 1 and am able to get a length of about 32" of finished cane/walking stick on the rotary axis then on the table I cut a 2-sided handle and use large diameter dowels to join the two pieces together. However, due to the downward pressure of the bit, the blank sagged in the middle and the carving was less detailed in the middle sections.
As a result, I started the next trials making the blanks in 3 pieces to keep them shorter, about 16" each. This solved the flex problem. I then used pool cue joiners to assemble the pieces into a 3-piece walking stick. A good idea as it can be disassembled for storage BUT the joints are not solid enough for walking with and will break. So basically...a fancy show piece now.
Attached pictures shows 2 walking sticks...one screwed together with a wrap-around snake and the other in its 3 pieces...v-carved mostly.

Re: What keeps you from using your rotary axis?
Yes, I'll try and address some of the problems people run into that keeps them from using rotary. I will focus on the very elementary things that trip people up.Is this information going to be shown / shared at Jim McGrew's Camp in April ??
Gary will handle the part of the presentation where he gets the rotary to sing, dance, and impersonate Elvis. <wink>

Re: What keeps you from using your rotary axis?
I use mine all the time. There's not a room here to show all my the projects I use my rotary on. Last year I got a bigger one...after all I needed to carve a pumpkin.If you do have one, have done anything with it yet?
On a machine I sold shortly after I bought it, I had to switch the X axis to the A axis and recalibrate it everytime I switched, so if anyone is going to get one, a dedicated 4th drive to run the axis is recommended.

Re: What keeps you from using your rotary axis?
For those with an unused rotary...
Do you have to swap a controller and/or a motor in order to use it?
Does it sit in/on the bed of the table or off to the side? i.e. do you have to set up/tear down something to use it, or can you quickly switch between table work and rotary work?
Have you ever hooked it up, and can you turn it with your control software?

Here are some goodies for you all to think about.

Randal: "Gary will handle the part of the presentation where he gets the rotary to sing, dance, and impersonate Elvis. <wink>"
Only if Elvis poked hornets nests with a stick
I doubt that, but.... How about a little VCPro "conversational" input to make one of these bolts?
Did you "rotary heads" know that VCPro will:
Allow you to mix indexed and wrapped cutting in the same job?
Allow you to rotate the rotary axis between multiple 2d toolpaths on indexed machining?
Allow you to do continuous rotary machining of a "spun" profile such as a hourglass or bat, etc.?
That you do not need a "Rotary Wrapped Setup" gadjet for anything? Or any of the rotary gadgets, for that matter?
That outta stir the pot

Re: What keeps you from using your rotary axis?
Hi: My smaller CNC has a removable 4th axis rotary drive. I use it to engrave pens made by others. I've made rope twist molding
both left and right direction. I make Corian cups and do lithopanes on them with a votive candle inside. Norm

Re: What keeps you from using your rotary axis?
I aquired a rotary axis along with another pile of bits I bought but I've never connected it.
I don't need it.... do I?
I can program my way round it like I've always done
Oh go on then, please ease me into it gently with some irresistable projects :-p
