Slate Coasters
« on: September 22, 2018, 10:02:30 PM »

I caught the slate coaster bug bad, and I've actually got my first sale
already.  The owner of the card house where I deal poker has agreed
to buy coasters with the card house logo on them and sell them to
members.  Here is what I'll be selling.  I'm working on other coasters,
and I'll be posting pictures in this thread.

Thanks for infecting me with the bug y'all.  You've managed to eat up
all of my free time and money :-)

Here's a set of Star Wars based coasters I'm making for my lightsaber group.
I'm going to add ones with the group logos, but they're a little more difficult
and complex.  So nailing down the image is taking some time.

Here are two demo coasters I made for a charity event being held next month.
Once I decide on a final design, I'll make a couple of sets and put them in an
auction along with a medal hanger I'm engraving on a Basswood plank.  I'm
hoping they'll fetch a nice return for the charity.

If you buy nice thick slate coasters you can sand any images off and start over, I found this to be very useful when engraving pictures as they are more complicated (sometimes you need to invert the black / white for the picture to look human!).
This way if you have a test piece of slate you can sand it and keep testing on the same piece of slate, I use a belt sander, careful of the dust produced!
Nice results, well done!

I have been able to sand the image off and reuse the coaster of test purposes. The original finish is much better. Wonder if it is wet sanded or polished. My stack of dead coasters is growing!!

or it could be the natural finish from when they cut and split the slate...?

I use:
Speed: 850 / 1000
Power: 0 / 255
Resolution: 0.1

The image files are 800mm square, reduced to 80mm by T2. I've had
Some success doing fine lines and shading but mostly stick to simple
Black and white.

Please elaborate on greyscale. If my understanding is correct (very questionable) the laser heat causes the slate to fracture. The etching basically a series of small explosions. Either the rock fractures or not. I have seen no noticeable difference in depth or color. I have seen differences in line width and kerf depending on laser power and speed.

BTW Sir Nottingham - you are responsible for over 300 slate tiles being tortured in my basement.

News Flash - "Slate Abuse scandal rocks Washington"

President Trump has announced that he will appoint internationally renowned rocktologist Steve Notinghham to to lead the investigation into the alleged wide scale abuse of native slate.

Democrats question the wisdom in appointing the "accused" chief abuser and have asked the FBI to investigate and as this will require Senate approval the wish to defer any action for 7 years.

23 slate owners have filed papers stating that they are sure that their slates were molested and demand that they be allowed to present their case before Congress.

ASPCT (American Society for Prevention of Cruelty to Rocks) has started a national program designed to educate the public and raise funds for sheltering abused slate times.

The Michaels for Mens club says things are going great.
