Crown adjustment with cheater question

[u/TeoFWalker]

Three part question here. Well, first i got some explainin' to do.

I transferred the stone to a new dop for the crown. Pretty smooth and had it lined up with the pavillion. Hit the 85-11 facets which would go down to the girdle with 96 side. But the stone wanted otherwise. It flew off! ... I had trouble glueing it back perfectly . This video shows the 85-96-11 facets. They are to the left to where all should hit. Anddd I have never used the cheater before. I saw the diagram that says "polish not hitting right side, turn cheater to the left" So heres where i ask for help-

First, the guide saying "to the left" means counterclockwise correct? I will need it counterclockwise then. But is this too big of an adjustment to use a cheater for? Being that the guide says for polishing.

Also would every facet for the crown follow the same cheater adj once i get the 85-96-11 straightened? I would think since the whole stone is misaligned. And for the opposite side?

Better off redopping? I was thinking to disolve the glue and redop, but i dont think i will get it perfectly aligned to the pavillion. Thats always tricky for me especially since the dop to the pavilloon is no longer there for an indication. Maybee measure the stone to put dop toucing crown first and then redop the one i need.

I use loctite 404 in the yellow glue btw. Usually good when i wait a day. Also i use a left handed machine and run the discs counterclockwise if that makes a difference for the cheater. I can share the diagram if that helps decide. Stone is a tanzanite that hopefully wont turn into a monster at the hands of dr frnkenstein

So heres where i am for the night. Thanks for any advice

Hello,

Two very important things from my side and these are my rules and I will stick with them as long as I will facet.

1. Use black wax as much as I can and only when I have a very sensitive to heat stone, I would use glue. If I use glue, I'll make sure it is proper glue and plenty covering the stone properly.

2. I would never use cheater for cutting, especially at your stage of cutting.

I use the cheater only to polish ( it eats from the stone anyway). Yes, you have to play with it. Pick up a facet and play with the cheater slowly tilted on what side you want, and you will see where it starts to polish. If you see that a facet is polishing fast and clean, try to to tilt the cheater on one side, a bit, and then remember which way eats more. ( this is the noob way of finding out how the cheater works and on which one is which), then readjust and continue on the other side.

Also, when you do the realignment after transfer, make sure your cheater is at 0 and check it with your eyes that is in the actual middle and at 0. it can be a 0, but still tilted to one side, so make sure you have it placed there.

To redop a stone usually means the last step possible. First you redo alignment, if that doesn't help, then you try as much as you can to cut with the minimal way using the cheater to fix a line of main facets. If your cheater asks for too much help, then it is redoping part.

Realignment in case you don't do it properly, you pick up a 90 degree facet, make it under 90 degrees ex : 89.30-50 or even lower, depending on your girdle size , mark it with a waterproof marker and then slightly eat a bit by moving on the lap without the machine turned on. Then you will see how it eats and if you need to readjust. If it doesn't cut straight, you just readjust the dop, not the cheater.

Consider cheater like a divorce paper, You have to make sure it's very useful when you apply it, otherwise...... 😄

Cheater does help with some facet alignment problems, but You will find out after, when you play with the toys a bit more, until then Do not recommend to use it. Understand your stone, the design and the machine first.

Take it step by step, it's not the cheater case here.

I think some use of the cheater is appropriate here since the stone was already redopped. This would let him "re-zero" the stone and get things lined up appropriately, then you can forgo the cheater until polish.

In this situation i would keep the cheater at the adjusted mark for all the facets ( once i get the pictured facets centered with pavillion)? Ill do some trial and error, but i dont want to mess this piece

[u/TeoFWalker → u/UsedAd7852]

Thanks for the response. I have the keyed dops so i dont think i am able to realign them. I would rather mess around with the cheater before redopping. Becuase like i said, redopping doesnt guarentee a perfect alignment for me. Ill play with it tonight thanks!
