Ask a "Silly" Question / Re: Boulder Opal/Yowah Nuts HELP
« on: September 17, 2020, 07:06:33 AM »
You could google Opticon fracture sealer and see if that will do what you want. I read the instructions but found them unclear.


Apologies for posting a product link but if you go to the listing here and click on the small pdf icon just below the product photo, there is a document we have posted describing how to use Opticon in a bit more relevant way for lapidary.

Might be helpful??

If you posted a way to contact yourself I could give you a phone number for the owner,  but I wont do it on line.

You can private message the OP.  Yes - agree not to post phone numbers online without permission but send can send PM.

Point taken. I will put it all together on my PC, text, pictures, drawings, in a building sequence that I'm happy with. Then post the whole lot on a new thread in one hit. That way its all together and can easily be followed. Not sure on how I go about claiming copyright and have never written anything in pdf format. So will just stick to posting to a thread.

No problems.  I or Andrew can help with putting together IF you decide you want to. Also really valuable to post it in a thread here as well.

For pdf, just needs to be put together in a Word document or similar - it can then easily be saved as a pdf with your name in the footer - an author's name is all that is required to retain copyright of your work.  By saving it as a pdf, it makes it slightly less easy for others to modify in ways that you might not want.  Of course, a thread here allows others to contribute as well which helps the overall knowledge base.

Don't have any interest in copyright.

Even if you intend to post the information for the benefit of others with no intention of monetary profit to yourself, I always think you should at least make sure your work is credited to you - that is only fair.

Hi Frank,


this information is likely to be of great interest to many people.


When you have finished getting all the drawings and instructions together and are happy with it all, you might think about putting it all in one separate thread or uploaded as a single pdf file.  Obviously your choice how you want to publish but we can make it a sticky topic to make it easier for people to find.  Remember if you do put it in a pdf file to attach your name to it as a footer or something similar so you retain ownership and copyright as this stuff can be copied and sent far and wide.


Cheers
Leah

Not getting the size of the drawings when posting them to the forum for some reason. I have to save them from .CAD to .JPG before posting and they occupy the full screen on my computer. After posting them they are surrounded by all this blank space, making them tiny and difficult to see.
So will have to work out how to maintain the size.

Can you crop the jpg file to remove all the white space?  Any image editor will be able to do this.

cheers

Just to rehash a 4 year old thread with a newer one - original and updated links no longer work possibly related to Downloads not loading from the menu?

I will look into this this afternoon and fix up.

The 33B is a great option but unfortunately we (Aussie Sapphire) and other Australian dealers have run out of this model.  Due to covid19 factory shutdowns in the US, Lortone were only able to supply half of our last order and have made little progress on our current order (placed immediately when we got our previous order).


To date, they have been unable to tell us when they can supply more stock (has been on order for at least 3 months).


So doesnt look like we will get more 33B's any time soon.  Getting low on all other models as well but not quite run out.


We will give updates on our facebook page when we know more about ETA.


The 45C is a good tumbler with a bit larger capacity than the 3A but is only a single barrel tumbler.  All comes down to what size batch and up to what size rock you want to tumble.


Cheers

Get well soon.


My Dad fell off a ladder a couple years ago - was not a good experience.
Was a completely ridiculous situation and when we asked him why did he get up there in the first place (2 minutes thinking about the job would have made anyone think twice), he answered, it was his ladder and he was the youngest bloke there.  We have since banned him from ladders - maybe your "boss" will do the same.


Hope your injuries heal quickly.


cheers

Got it! But my gem photography needs to improve. Having trouble uploading a photo. Getting a massage, Not A Valid Picture File? Never had this before!
Any ideas?

Cheers

What file format are you using?  There are lots out there but I think the Gallery is set to accept only the main ones.

The cut with 3k on brass is fairly aggressive, I'm not sure if going straight to 100k on aluminum will pollish harder materials.

We have sold a zinc lap from Gearloose that tended to be quite aggressive with #3000 as a pre-polish.  He used to recommend using #8000 diamond instead for pre-polishing on that more aggressive lap.  Maybe that might be worth considering on your brass mandrel.

Possible they are mesh labels??

If so, 0/2 would be #14,000 grit.

This reference chart may help:

God I hate these file restrictions

We ask members not to post photos as attachments to messages as there is a size limit on that folder.
Please post them in the Media Gallery instead and then add it to your message using the BBC codes.

More info here.

It really helps us out if you do it this way and is better for those viewing the thread.
ALF is provided as a free service to the lapidary community but it does cost us money for hosting space, etc.  We choose not to offset that by selling advertising because I feel that is annoying to those using the forum but admin-wise, it is a lot easier for us to store photos in the Gallery folders instead of the Attachments folder.

The motor is actually 230 Volt.  The 3A or 33B tumbler motors are 0.33 Amps so pretty cheap to run.
