Robin,

I know of the e-mail list to. Just to lazy.

I have the model that came after the redwing, the BattWing.
It uses an outer band of BATT alloy and a Darkside alloy on the inside for polishing.

I've looked at Jon's webbsite, also many good tips.
Been following his progress a while now..

Gotta run though,
Willie

Wow, it sure looks like there is a lot of interest in faceting among our members, not to mention some great talent! There is lots of great info in this thread, but the thread is getting so long I am afraid some of that info may get hard to find... I think it may be time for a faceting board on this forum. Just promise me you guys will keep contributing new posts and populating the board with great info like that found in this thread!

My wife gave me a old American Facetor for Christmas of 2010. I have yet to use it. I really need to break that machine out and start making mistakes so I can learn.

I still am a little baffled by the pavilion. When you are roughing it in at the beginning how do you know how deep to go, especially with an odd shaped piece of rough? Maybe that is a silly question because of the indicator but that only gives me the angle. Is it pretty much trial and error until you can fit all your facets cleanly on the pavilion? I guess what I am getting at is how do you estimate a piece of rough? How thick does it have to be?
Thank you for your patience everyone.

I have a old facetor with a burned out motor. :( I would like to try faceting someday but till I can get my hands on a machine that works or make something that'll work it'll be awhile till I get to.

   A good faceting design will have ratios available. These ratios are length / width , height to width, pavillion / width etc. The design will also indicate which facet will cut to the depth of the pavillion and whether this is the permanent meet or a temporary meet. A beginning meetpoint book that takes you from easy cuts to harder cuts in a logical learning progression is worth it's weight in gold.

Nuevo, no promises but we'll do our best! lol

Christopher,

It depends on the pavilion, let's say we have 2 types of pavilions on "standard" designs:

1. Knife edge culet, basically just a long, thin line in the centre of the stone.

In the roughing in stage, lets as an example say you use a 360 lap.
You grind until everything is in that nice little line, every facet "touches" that line.
Something like this:


Compare with this one which hasn't been cut deep enough, you can see not all facets are "meeting" that line, some are down right missing!



2. Culet, basically a centerpoint where all the "main" facets meet.

How to cut it varies, I like to cut in the break facets on the pavilion first to a centerpoint. They would all make a sharp point on the stone, and no facet should look longer/shorter then the other under magnification.

I'm not sure this makes sense if your new, if I remember I'll take pics next time I facet a stone to show what I'm talking about. Pics can say more then a thousand words.
But it looks like I have some re-cuts first in line. dancer5

Connie, depending on what kind of motor maybe it can be replaced?

Frank,
I agree a good book is helpful. But these ratios is something I've never cared about, except to make out the size of the table.

Christopher, I'll get started on my little faceting tutorial "re: how deep to cut?"
Just dopped a topaz, It'll take a while though.

Lots to do the next couple of days. :)
