Seems simple enough, not mine. Tried it? Thoughts?

Thoughts on this????

I knew someone would post that sooner or later. That is a prototype. That I thought I had a verbal agreement that he would not sell it. But I guess not! Anyway, as soon as I get done testing the equipment that I had him make for me I will have these available as either a add on for existing machines or as a complete package.
Repeatability on a stepper motor and low priced lead screws are going to be a challenge.
Can that machine maintain .002 over the size of the carbide sanding mandrels on the last pass ?
It's a tall order I think.
Also, it being a 2-axis system will have some safety challenges I think.
Once the cuts are finished, your Home position has to be away from the centers.
On 3-axis, you could go home to X0Y0 on safe Z level.
Todd's a great guy and I hope the project becomes a great taperer.
Well, LOL, I guess I will be doing the DVD.
Joey, you are correct but no where is it written you can't add a 3rd or 4th axis.
I know this guy that makes dead nut center fixtures for that type Head Stock.
We could be seeing the future of cue building.

I tried this exact thing a few years back and it failed miserably on me. To many little problems and variences. Hope it works out and you do better than I did. Can't say I was the most knowledgable guy for the job then or even now.
Tom,
You said you were going to look for a lathe - now you've got one!!! All you have to do is learn enough G-Code to do tapers, though it's not that tough. Or you could go the CAD/CAM route and learn some more software.
One thing you may want to be looking into is a way to install reliable home/limit switches (I don't see any). Without limit switches, your new lathe could chew itself up on the first "oops!". Without accurate home switches, you'll be hard pressed to get the repeatability that you desire. Mach3 will let you do double-duty on those switches. It is all do-able.
Good Luck!! Have Fun!!! And keep us all posted on your progress!!

Gary,
Not many know this but during my RT Custom Cue days I owned my first CNC machine by L. Bludworth and was trained on BobCad 1 by Donald Bludworth in Leaky TX population 603. This is back when you needed a key in the back of your Pute to use BobCad.
We went on and had a 4 tier 4 saw blade vertical CNC by Blud that would cut 4 shafts or 4 butts at a time.
Oh, LOL, I will have to brush up quite a bit as I was by no means the mastermind, more like master of disaastor.
Your kind tips are registering though and appreciate the tips and any more that want to be given. It aint quite like riding a bike and I fell off my share of those as well.
