Jared BrinkerMy latest tool
Just picked this up on ebay. Might have cost me $100 to get it, but with 4-5,000 crystals i have that are unmarked on their size, it will pay for itself tenfold!

Edward L. Parsons, Jr.Nice item, I've found my crystal gauge very useful for sizing crystals w/o labels. I write the size on the crystal with an alcohol marker.

Mike LaForestWouldn't that make a dandy thing for IHC to reproduce and make available to IHC members at a more affordable cost...

Chris AbellSteve,
is there anyway you could also include the MM conversion
CHART also I find the fractional lables not to be accurate between brands
June 25, 2011, 09:42
Steve MiddlesworthChris,
I'm sure that could be converted, it would just have to scaled a little differently to try and work in even metric increments.

C. Keith JohnsonHi all. I have a conversion chart that came with my crystal cabinet. It is a hand drawn three way conversion chart Ligne-metric-and American sizes. My scan was too large to send. If anyone wants a copy just eMail me your address and I will send you one.........Keith ..ckeithjohnson@eriecoast.com

Edward L. Parsons, Jr.If anyone would see how these gauges are used to determine crystal size, check out this prior topic:

Francis BowmanQuestion???? is this only for round crystal or can be used for all types? squares for WW???
June 25, 2011, 18:50
Edward L. Parsons, Jr.Francis,
There's no reason you couldn't measure a square crystal with this type of gauge, but determining the point of tangency where you read off the intercept would be somewhat more tricky than for a round crystal.
Personally, I would prefer to use a caliper for a square crystal.
Best Regards,

David AbbeI still find accuracy is my best friend so I use a dial caliper to measure the bezel and "convert" the size (INCHES) with A "Size Chart"
BELOW. Of course we have William White, the A1 grade crystal maker right here to "fill in" with the actual correctly ground and sized crystal . . .

Francis BowmanThat is what i love about this site. Throw out a question and U results plus much more...what a great awesome group to belong too.

Cecil McGeeHey David, Thanks for posting that chart. I printed out a copy,and checked it out. Works good.
June 29, 2011, 17:06
Stephen John WardI simply use a 1"-2" micrometer which gives a very accurate diameter easily to within 0.001" and better.

Jared BrinkerLindell and David-
I emailed you a PDF version of the crystal gauge to look at and check for accuracy. Let me know if you didn't receive my email with it.
Thanks,
Jared

David AbbeJared, I received you picture and am checking a frind who does laser etching to see if we can make an all metal "edition" of this gauge. I would like to help design it so we can use it to scale Crystal Bezels also as what we need these days is a reliable way to size bezels for replacements.

Dr. Debbie Irvine
Both Steve Middlesworth and Jared Brinker sent Lin copies of the drawings and they look very promising.
Thank you,
Debbie

Steve MiddlesworthDave,
I can send you a dxf file if that lazer etcher is cnc.

David AbbeThe laser shop can use the picture Jared made and fine tune it with the dimensional chart I gave them. It will look and work like the one Jared has but also has a "hole pattern" to use small dowel pins to gauge crystal bezels in the 12-18 sizes.
I will to mount this on a nice walnut base at it will be printed on a brushed stainless laminated black plastic to show black inset printing. When a sample is ready I will show pics.

Richard M. JonesA great idea and what a fun group IHC185 is!
