Gemstone Faceting / TV glass toxicity?
« on: January 26, 2019, 10:26:00 AM »
I've got a huge amount of test cutting to do and thought TV glass would be good. Soft with a reasonably high RI. Just the thing for quick nasty faceting.

So I dragged the big old 90cm CRTV out of the bottom room, pulled it to bits, removed the vacuum, put contact film on the screen(left over from the kids school books), covered with a towel and carpet tiles. Then gave it a good wack with the sledge hammer. The shattering radiated nicely from the impact point and in no time at all I had a bucket full of glass ready from faceting  ;D .

Cubed a few bits by hand on the saw, but then....
Hmm, I got thinking about lead :o and hmm ??? though it might not be a good idea. So I did some reading and luckily the glass from the screen fronts is usually fairly low in lead. The screen glass I have has a light grey tint to it.
So the question is has anyone here got exp with tv glass?? Is it safe for me to facet it. It was from one of the last models produced (about 2004 Panasonic). I realized the tube glass is very high in lead, I'm hoping the screen glass might be ok. I've read screen glass for colour tv's was commonly lead free barium/strontium glass.

General Discussion / 403 errors
« on: December 16, 2018, 11:32:11 AM »
Hi,
I'm getting 403 errors, especially if our VPN is running. But I've also noticed with the VPN off I get errors when replying to other posts if I quote the previous post.
Using firefox, maybe I should update it.
Anyone else getting these errors.
Cheers

This appeared in my saved search. Nice little saw by the look. Could try to get the price down a bit. In South Australia. They want $350

Cabbing and More / Fern Knife
« on: December 08, 2017, 09:13:02 PM »
Finally got my act together today and finished a knife(one of three) that I've been meaning to do for about a year. Didn't take too long.
Happy with the result, inlay is close to perfect, metal bolsters still need a bit more if a polish. They have a few fine scratches but I'll probably just leave as they are hardly noticeable as will easily get more.
Jamo, I think you wanted me to do a tutorial, I'll try on the next one.
Pretty sure it's a buck squire, it was/is a new knife.

Gemstone Faceting / Mystery Stones
« on: May 18, 2017, 09:58:05 PM »
Have a guess what these are? I cut them a couple of days ago  ;D Great colour and sparkle nicely, look a good bit better than in photo. 7 fold srb' cut on my 28 index. I cut them fairly fast so a few meets are slightly off. Should have cleaned them a bit better looking at the photo.
