Re: finding DEAD center on Rotary Table

Tim,
I think what Curtis is pointing out is:
You may have marked DEAD Center on the Rotary Table - BUT, if you don't have that point perfectly in line with the center line of the LOM, when you start milling (cutting rosettes), that slight misalignment will make itself known to you quickly.
Be Safe & do Good!

Thanks Curt,

Ok that all sounds good then finding the center to start your rosette is the challenge. 
I even started with center lines and set the bit in the exact dead center so I thought. hmmmm. 
better sleep on it. lol its getting late here. 
Kind Regards,

HI Tim

I have found the easiest way for me, is to use the "drill center hole" idea.  Then use a pointer mounted in the router of the Legacy. and align the table and the router, then you can use that for your 0 mark/ reference point, Once this table and Router are aligned you can touch off any know point, to take you measurements from.

Ok all you rosette guru's or rotary table users,
I have a question and I want some serious input
here on my subject. My whole WoodCraft Ind. career
I worked in the tool room as a Tooling Tech, so with
that said I worked with 10/thousands and even tighter
tolerances much lick anyone out there that is a machinist.
Ok so my point is even with cross marks on my table and
lining up a perfectly square piece with corners to lines 
Its still hard to find dead center. Now I have considered
boring a centering hole in my work piece but should not
have too. I also find the center of my work piece and center
the bit. So my point is I have a lot of skill centering but
some how I am not always hitting the center. 
Yes I have a square work piece. 
What are some of your secrets for finding DEAD center. 
Has anyone tried touching off the corners or?????
Usually you don't realize your out of center until you go around it 
with a bit especially if you are doing a sunburst or something. 
Lets dig up some good suggestions I need repeatability not hit
and miss. 
Thanks
