Rotary Projects

[joeblow]

Interest in rotary seems to be picking up a little bit here so I thought I would post a couple pics of my best rotary jobs completed in 2020.  Funny thing is I actually got into the CNC world specifically for the rotary and I couldn't be happier with it.

Easter Egg Grade A large

Osage Orange with silver, turquoise and cayenne pepper inlays. 

Walnut "basket" with osage orange inlay.

All inlays were completed while on the rotary.

Jack Daniel's bottle in white oak with walnut inlay.

Inlay completed while on the rotary.

Thanks for looking.

I am more than a little impressed here and curious as to the process. If you are willing to discuss:
EGG:
1. Did you create a glueup and do the egg and stand as a single piece? If not, how did you make the hollow in the stand to match the egg bottom?
2. For the inlay, did you cut all the female parts while on the rotary, then cut the male parts and insert them one at a time? Must be a very fine (like 10 deg) to get that detail yes?
3. You cut turquoise on your cnc? No shattering?

JD bottle: Must go try today. That's awesome!

Awesome work. What software did you use to model these?

Thanks Zmuda.  I used Aspire for the modeling.

Thanks DustyPilot.

1.  I was wondering if someone would notice the egg depression in the basket.  The egg and the basket were cut separately on the rotary.  The egg itself was a glue-up because I didn't have a large enough piece of osage orange at the time.  Anyways, the "petals' or top of the basket were cut on the rotary after the 3d finishing toolpath.  I used a squiggly line as the vector and a 2d profile toolpath with a cut depth of .15".  Then I cut a small fixture/jig for the basket and hollowed out the egg depression with a small dish model.  This was the only cut done off the rotary.

2.  All female cuts were done on the rotary for both the JD bottle and the egg.  The egg did not require male parts to be cut as the turquoise and cayenne pepper inlays were both in "powder" form.  The silver was a thin silver beading wire.  I like to use the cnc for male waste removal so once the inlays were complete I ran the finishing toolpath one last time.

The male inlay for the JD bottle was cut on the flat and glued in while the piece was on the rotary.  Once again I ran the finishing toolpath for waste removal.

3.  Turquoise is actually quite soft in its natural form.  The majority of turquoise on the market is stabilized and I would suspect it would not cut so well on the cnc.  The turquoise I have is in its natural state and I ground it down and used the CA method of gluing.  I've done a couple of turquoise inlays so far and each time they cut beautifully on the cnc.

Vectric's tutorial "Modeling a spindle on the rotary" was essential to creating the JD bottle.  Very informative video and I used every strategy presented to complete this piece.  I just had to make it usable as well....
