Parts and information on a Agate Master faceting machine
« on: March 31, 2019, 03:50:49 PM »
Hello ALL,

I am new to lapidary and a friend of mine has given me an old 6" Agate master faceting machine (see Attached) which I was hoping to refurbish. I think the company is no longer in business as I cannot track them down on the Web.  I was hoping that someone on the forum could give me a lead on where I can acquire copies of owners or workshop manuals, sets of index gears and possibly other spares \ laps etc

Thanks in Advance

Peter

I will start with the easy one, the laps.
The very nice people at Aussie Sapphire will be able to fix you up with them.

Other parts will need to be made by someone with a machine shop.
Dops I think are Quarter inch dia brass rod which is reasonably easy to source.
Do you have any index wheels, I am thinking you will probably have a 64 so if you want a 96 you will need to get that made, most faceting diagrams these days are for 96 index wheels. 80 72 are a bit esoteric so you will not normally require them unless you want to facet pentagon shapes.
Gear cutting shops will be able to make your index wheels for you  but they may be a bit pricey.
Another essential is a transfer jig.
As it's an old machine make sure the wiring is up to scratch, those old rubber coated leads and wires can get brittle or gooey neither is good as it could leave bare wires touching things.

Also have a look on the forum, there was a rebuild thread for an Agatemaster about a year ago.

One other thing I forgot was the 45 degree dop for doing the table, It's a strange looking thing with a hole drilled through at 45 degrees, to go with this there should be a large flat dop as well for lining up your 45Deg dop with the lap.

Thanks Rusted for replying

Yes I contacted Aussie Sapphire and have been kitted out with laps and other things. 

Luckily I also received a pretty good set of Dops of various shapes and sizes from my friend.

In regard to the 45 degree dop and large dop, I have included a picture of what I have, is this what you were referring to?

The transfer jig I have is a bit worn from age, but appears functional - time will tell as I start  to practice on some low quality quartz stones I have to get my eye in.

There are two 64 index wheels one looks unused - I'll search around to see about getting a other index wheels and hopefully it won't be too expensive.  I am in a gem club in Brisbane and they tell me that they have some conversion charts and I another member on the forum is also helping in this regard.

While the machine itself is old the electric motor appears more modern and appears in very good condition, no frayed wires.

I'll check back in the forum for the earlier posts you mentioned

On the Web Site : Facet Designs Database, search on designs for 64 index and you will get 848 results, of which 262 are downloadable.   These are designs you can use in addition to those that will be available from the conversion charts.
The conversions charts work as thus: If a 96 index design's index numbers divided by three and multiplied by two results in all whole numbers then you can use the design in a 64 index machine.
Regards, Ghost.

Hi PCH,

Which club are you in?

I'm in Waterloo Bay club, and the Facetors Guild.

Conversion from 96 index isn't hard, just multiply each index by 64/96 or 2/3.

Ideally you will find 96 index diagrams with indexes that are multiples of 3, otherwise you'll be working with fractional indicies  :-[

There are a number of 64 indes designs out there.  The Murray Bridge Gemboree had some in their competition.  Some also appear from time to time in the Australian Facetors Guild magazine, Facet Talk.

Pm me if you need help sourcing 64 index designs.  I have quite a few in my database.

Dean Baker on the Facebook Group, Faceting Technical, recently had a 96 index made for his Agate Master.  It cost him $120.

Regards
Gordon
Yours Sincerely

Yes PCH thats the 45 degree dop.
For cutting the table put the 45 dop in your quill then the big flat one in the 45. set your angle to 45 on the scale, that 45 and the 45 in your dop gives you 90 degrees. line up your flat dop with the lap, keep in mind that depending on the state of adjustment of your machine the 45 on the scale may need tweaking to get the flat dop flat against the lap. replace the flat dop with the dop that has your stone attached and carefully cut your table by slowly winding the stone down onto the lap.

I live on the western side of Brisbane and joined the Ipswich club who are a great crew really helpful.  I joined the FaceBook group and will check it out further after some practice.

Hi PCH,

 Graeme McLean is one of your club members, he's also a judge and member of the Moreton Bay Group of the Australian Facetors Guild.  If you get a chance  have a chat to him about faceting and the Guild.

The Guild publisheas a bi monthly magazine that is well worth the annual membership fee.  There's a sample on the Guild's website.

Regards
Gordon.
Yours Sincerely

The facetors guild magazine is definitely worth the modest cost of membership - cutting designs along with other articles of interest.


cheers
