Thanks Rusted will check out the areas you suggested.
A few people have suggested that digging is also worthwhile and can produce better specimens than just specking (I have a digging machine that doesn’t mind the heat....runs well on home cooking and beer beers
Chat with everyone, a lot of people will help. Last visit I had a good hole that was producing crystal and I was able to trade days in other people digs.

Got another couple of questions on the location around Gemtree & Hart's Ranges. What is there locally for fuel and provisions?

Cheers  beers

PS Does Gemtree  C/Park have cabins?
It's 280kn return Gemtree to Alice Springs, best to get all your food and fuel at Alice Springs. Fuel at Gemtree was about $2.50lt so only for emergency imo. I did a return trip to Alice halfway though our trip to resupply. They have some accommodation.

We were there in July, thought the weather was pretty good. We had the van at gemtree and day tripped. Days were warm enough for shorts.

When I was on Flinders Island last, they lady selling topaz in a shop had a 3300ct blue on display. Was a bit cloudy, she said she had turned down an offer of $20k for it.

Thanks Flash, I wouldn't worry about the oscillation bearings too much just keep a bit of light grease on your rails. I'm going to use plastic ones as they will run a lot smoother. My brother has them on his 3d printers and they are really nice.Easy to swap into the housings you have if you decided to.

Sounds like the police and mining inspectors need to be told of the trucks behaviour.  Not supposed to be in convoy like that
Got to wonder about the economics of trucking gold ore 600km to process. Operation has got to be marginal. Maybe it won't last too long.

I think you can also visit the information centre and get directions/pay a small amount to go to a number of digging locations.

How much horizontal adjustment have you on your machine Flash ? How much do you reckon you need?

That's a monster, bigger than the one stolen from Mt Surprise. Is it cloudy or fairly clean?A stone that big can command a big premium due to being so rare.

Quartz is one of those materials where each faceter has his/her own special mix.

To add my 'two bobs' worth, I polish quartz using 60k diamond on a pure tin lap running fast, having pre-polished using 8k on copper. Yes it squeaks and growls, but I've never had a failure and I use an LED work light which causes cat hairs or any other fault to scream at you. Couple of wipes across the lap with a little pressure and the facet is done.

I tried Cerium once and it was a disaster, never been back
I do as well but 100k diamond on what I think is a tin tap, but not 100% sure. It just doesn't want to scratch anything. I also knurl the lap when I load it.

The opal from opalton(near Winton) I think they call it fairy opal(in sandstone). I was told to form to rough shape and soak in superglue then polish. I'm not sure you cook it like he andamooka opal.

What diameter are you using for your mandrels? I have 6mm stainless from printers aswell, that may be better to use as most of the brass rod I have is very slightly bent. Brass should be nice for a prepolish/polish.

Yes the lathe is new and I was pleasantly surprised the 3 jaw is as good as it is, I haven't used my independent 4 jaw chuck yet.  You can see it in the youtube clip. I have fitted steppers to it and can use manually or cnc. I have a quick change tool post I have to fit to it which is on the to do list aswell.

One cut might even do, that is how I was machining dops.  But I was thinking I might just try drilling the stock, turn to size, loctite in the brass then part off the mandrel.

Welcome Lily, Vibration mounts could well help. If you can isolate the motor from the faceting machine frame it will most likely get rid of heaps of noise. Maybe make a rubber gasket and use grommets/washers on the mounting bolts.

 I also used FatMat car sound dampering mat to get rid of a heap of noise in my lathe coming from the motor, but that may not help much on a faceting machine.
