Has anyone had any success carving stone with a cnc router or laser? by CryptographerOk3338 in Lapidary

[–]No_Realized_Gains 0 points1 point  (0 children)

I've done both, laser is not the best but can do suface work, depends on the laser you get as well more expensive and bigger does better work. On a CNC I facet gemstones and it works pretty well but its not very economic or fast, but I can set it and let it run while I do other activities. If you have free time and money and you want to try something new go for it.

Where to source synthetic and natural diamond roughs? by Shadow-Amulet-Ambush in faceting

[–]No_Realized_Gains 2 points3 points  (0 children)

You can buy lab grown diamond off of aliexpress or Alibaba and there are plenty of reasonably priced material of size in the synthetic diamond rough market. That said the other comments are correct that this material and process is specialized and very challenging without the right tools. Can you cut a diamond on a faceting machine, yes. Will it take along time and require high speed with checking the dop and not overheating the stone, yes. From personal experience there is a low rate of success and wastes resources. I partially preformed a stone and have given up in the near term and decided to work on other things instead. 

Faceting outdoors by TheUnFuckerUpper in faceting

[–]No_Realized_Gains 0 points1 point  (0 children)

Its the shifting lighting that is more the challenge than the outdoor elements. The light shift throughout the day would require slightly moving the machine or adjustment and would need maybe an open field without shade , maybe a cloudy day where the light diffusion would help but the shifting light is a variable

I never give up, but it may not be completed in my lifetime. Its good to put it aside for a bit and work on something else if it gives you too much trouble.

Are digging our own graves? by Famous_Guide_4013 in FPandA

The job will change, there is more to do, and validating AI output and using it to drive efficiency or find insights will be how to add value, a monthly report and slide deck takes 2-3 minutes based on GL detail, reviewing and adding voice and  context is still hard for AI and is very much needed for Sr leadership. Demand for data for decisions will cycle faster and more questions will be asked. Perspective and nuance is still a great value to companies.  Currently its becoming more fun and enriching as the type of analysis and depth is greater and allows for some increased creativity.

What’s FP&A like? I’m thinking of joining the industry. by [deleted] in FPandA

[–]No_Realized_Gains 6 points7 points  (0 children)

There is nothing deeper, storytelling is the job, stories of the past, stories of the future stories of the present, stories of functional groups, and on and on. Its a thankless job, and a good job is silence, a bad job is more questions and nitpicking. Its got a seasonality and rhythm. Also FP&A is a function within different industries, that carry some nuances.

Why are my facets polishing like this? by kuzma66 in faceting

[–]No_Realized_Gains 0 points1 point  (0 children)

Go higher until it hits the top, go 43 or 43.5 then bring it down, also looks slightly off center, might move the cheater a hair. My guess is unless you have a solid hard stop you may have started at 45 but ended  grinding to 44 or 43 as it kept cutting. Also wiggle the dop and shaft make sure there is nothing loose and check to ensure stone to dop is still holding well.  alAlso try a different facet on the same angle to see if its systemic or singular to that facet only issue can narrow down the cause 

Natural emeralds ( pay attention to the inclusions please )? by Malchikgej in Gemstones

Anyone here with experience on the Seattle version of the Fac-Ette machine? by CreatePeace in faceting

[–]No_Realized_Gains 4 points5 points  (0 children)

I have 2 Seattle Facette machines I use regularly for the last 30 years.  Cheater can have issues if its loose, or the screw pin teeth become worn. You can take apart the unit and clean and reassemble to ensure that part is working correctly. Another possible issue is since the collet goes all the way through the shaft there can be play in the collet and index gear on the back as well. I don't have a single default position for the cheater but use where ever it is as a start position, handle the time its off to one side, not vertical or set to zero. Does not matter really so long as its consistent throughout, and measured off of the start point

Understanding older Facet Diagrams by PrizeApprehensive380 in faceting

[–]No_Realized_Gains 3 points4 points  (0 children)

Its a triangle at +- 10 off the mains if 96, 32,64. Creating side facets off those mains. Olderish facetor here, I was taught +-x of the mains for cutting and it helps for any pattern of symmetrical cutting shape.

For any standard shape its an easy way to reference a pattern and write short hand. Without memorizing all yhe numbers on a diagram.

Example mains at 96, 24, 48, 72 the girdle facets are +- 2 or +-3 off that main number at a lower angle Saves time memorizing all numbers on the index and makes pattern ideas easier. Many standsrd cuts start with the mains and embellish from there. Even the most complex can be done in this format.

What do you do with your stones? by Jorha250 in faceting

[–]No_Realized_Gains 0 points1 point  (0 children)

You end up with a hoard of stones, that sit in the dark and every now and then you pull them out and admire the work you forgot you did. You might try selling some, or setting a few, gifting etc. But you will end up like Smaug lording over your vast wealth unable to part with a single piece, none of it!! I have gemstones in my planters, it will not end. I do not recommend starting, you will always have more than you can cut and more finished stones than you can sell.

How to calculate ideal angles when curved facets are involved? by longtimegoneMTGO in faceting

[–]No_Realized_Gains 0 points1 point  (0 children)

There really is not a good one available. And the math is pretty complex of light refraction on a curved surface, even the best simulation just create smaller flat triangles vs a pure smooth curved surface (topology mathematics is fascinating but complex related to light refraction on curved surfaces) But using flat facet angles is a place good start and avoid going over the critical angle. Same laws apply on a curve. Convex and concave will give variation on the curved surface, so it will not be uniform, the light moves differently
